Individual Sovereignty Narrative Question

Hi all,
This is a probably a pretty basic question for any of the Bitcoin OGs who are into running their own nodes but I have been hitting my head against the wall here a bit lately and was hoping someone can ELI5 this for me.
As you can probably tell from some of my prior posts, I'm a huge advocate of people running their own nodes and using them to send and receive bitcoin transactions. That said I admittedly have been relying on outside entities to be able to gather the transition hash for my outbound transactions when moving my BTC from exchanges (i.e. Conbase and CashApp etc).

Typically what I do is the following:

1) Search blockstream dot info (or any other reputable Bitcoin blockchain explorer) for my address that I sent the BTC to.

2) pull up the transaction output number on my bitcoin node via CLI with gettxout command and wait for confirmation on my node.

The problem here is that I'm relying on a third party to get my transaction hash to search in my own node. That said, what's the best way that I can avoid this step in my verification process. I'd like to be able to run my own blockchain explorer with my own node but I am not a coder so I'm hoping that there is a pretty straightforward way to go about this for a non coder running a windows node. Note that i do have the TXindex =1 already enabled.
Thanks in advance for your help!

How To Stake/Mine Coinevo

EVO Staking/Evo mining

Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total.
Basic requirements for staking:
  1. Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
  2. Have some EVO in the wallet (fullnode)(Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings.
Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being.
Two ways to stake:
Either way works in the same way for staking, so you can choose either method you like.

Method 1:Staking with evod (command line)

1. Run evod

Follow the guidance to run evod :
./evod -daemon 
Staking is default on for evod, so no need for other options if you only want to stake.

2. Send some EVO to your wallet

First you can generate a new address with:
./evo-cli getnewaddress 
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent
Please do following steps after your coin is mature.

3. Check staking info

Check current staking info with:
./evo-cli getstakinginfo 
You might get the result like this:
{ "enabled": true, "staking": true, "errors": "", "currentblocktx": 0, "pooledtx": 0, "difficulty": 3693409.779133397, "search-interval": 1577, "weight": 309584575558555, "netstakeweight": 1948540143266404, "expectedtime": 805 } 
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.

4. How to stake if the wallet is encrypted?

If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet.
Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet:
{ "enabled": true, "staking": false, "errors": "", "currentblocksize": 1000, "currentblocktx": 0, "pooledtx": 94, "difficulty": 5788429.670171153, "search-interval": 0, "weight": 53206430, "netstakeweight": 2438496688951881, "expectedtime": 0 } 
See staking turns to false , which means wallet is not staking.
You can use walletpassphrase to unlock wallet for staking:
./evo-cli walletpassphrase "" 99999999 true 
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.

Method 2: Staking with evo-qt wallet (official PC wallet)

Current supported platform: Mac/Linux/Windows.

1. Open Evo qt wallet

Launch the wallet.

2. Send some EVO to your wallet

If you already have some EVO in your wallet, you might skip this step.
Note:The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..

3. Check staking status

The flash sign at the bottom of wallet shows staking info :
Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Hollow flash measn it is not staking
Possible reasons for not staking:
No flash sign means staking is disabled

About block reward

The block producer will get more than 6.5 EVO rewards, something to keep in mind:

How to disable staking?

Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below:
1 Add -staking=false when running Coinevo node:
./evod -staking=false -daemon 
For qt wallet, it is like:
./evo-qt -staking=false 
2 Add config staking=false in evo.conf;
3 Encrypt wallet, since encrypted wallet will automatically stop staking.

Fun out-of-the-box web commands for Windows 10

No WSL required; these commands work in the command prompt without any setup whatsoever:
 finger [email protected] - a nice meteogram (also works in XP/Vista/7/8 by default) ssh redditbox.us - a CLI Reddit client ssh netris.rocketnine.space - multiplayer tetris ssh sshtron.zachlatta.com - a multiplayer Tron clone ssh [email protected] - a fun roguelike game ssh [email protected] -p 2222 - guess free minesweeper; Pass: play ssh brow.sh - a CLI internet browser (I haven't been able to click on things unless I'm running it on macOS or Linux) ssh chat.shazow.net - a chat room full of strangers ssh [email protected] - play various games including checkers curl https://tgftp.nws.noaa.gov/data/observations/metastations/KATL.TXT - METAR, replace KATL with any other ICAO curl parrot.live - a cute parrot animation curl https://icanhazdadjoke.com - shitty jokes curl pseudorandom.name - generates a random name curl dict://dict.org/d:computer - dictionary curl 12.io/ip - fetches your IP curl ipinfo.io/8.8.8.8 - fetches your geolocation 
If you enter “reg add HKCU\Console /v VirtualTerminalLevel /t REG_DWORD /d 1” then ANSI escape sequences will format correctly, which allows the following additional commands to output correctly: (and it colors the parrot)
 curl wttr.in/moon - see the current phase of the moon curl http://getnews.tech - see the top headlines curl cheat.sh - the home display for sub commands to programming resources curl cmc.rjldev.com - get coinmarketcap top 100 cryptocurrencies 
If you navigate to "Control panel -> Regional settings -> Administrative tab-> Change system locale" and activate "Beta: Use Unicode UTF-8 for worldwide language support" the following additional curl commands will also output correctly, IF you're using an advanced command line application such as Cmder or the new Windows Terminal:
 curl rate.sx - bitcoin prices curl rate.sx/[email protected] - bitcoin trend graph curl qrenco.de/STRING - replace string and generate a QR code curl wttr.in/cityname - get the weather forecast for your city curl v2.wttr.in/cityname - get a graphical weather forecast for your city 
These commands are now possible on Windows 10 since support for finger, ssh, and curl was added and enabled by default. You can setup a doskey for cmd aliases. Note that curl commands in PowerShell must be entered as curl.exe. There are also some fun telnet game servers as well as the Star Wars Episode IV ASCII movie (alternatively you can watch it with Netcat on port 23, "nc towel.blinkenlights.nl 23" which can be installed with Scoop, also try "nc rya.nc 1987") but the telnet feature must be manually enabled (run "dism /online /Enable-Feature /FeatureName:TelnetClient") and its known for being an insecure protocol. If you still choose to enable it, here's a bitcoin ticker and some fun game servers:
 telnet ticker.bitcointicker.co 10080 telnet freechess.org telnet aardmud.org telnet telehack.com telnet milek7.gq telnet mud.darkerrealms.org 2000 
I'd recommend Scoop as well as Pip (bundled with Python installation, which can be installed through Scoop and includes twitter and term2048) if you enjoyed these commands and would like more. Let me know if there's any commands that I should add to this list, I found most of them here!

3rd(?) best day of my life! AMA!

I was sifting through my things in storage. I used to be self employed doing IT consulting. I found my old computer. I thought I might have part of a bitcoin or two on there as I’ve been an avid bitcoin evangelist. So opened up a command prompt and in C:\ typed “dir wallet.dat /a/s” and I found one. So I looked and apparently I had run the windows GUI for bitcoind on this machine at one point.
I opened up the bitcoin GUI and the balance stated: 55. I was confused for a second and asked myself “55? Why does it say 55?” I looked at the transaction log and I saw two things: an entry for having signed a block and a payment of 5 extra BTC.
I live down the street from my parents and I shot up, ran out the door down to my parents house “Dad! Dad! We gotta go, I need you to come to my house right now, don’t worry about shoes!” Being a once in a life time event I felt he could run to my house barefoot and see this with me ... dick move I know! He was excited, he’s one of those guys that got on the hype train at 5500 and threw a couple hundred bucks in lol!
So I grabbed the wallet.dat, threw it up on my “vault” server I run, and waited for it to convert and scan the whole blockchain again. An hour later ... I am surprised I have my fingernails left... I typed “bitcoin getbalance” on my box and sure enough.. “55.00000000”. Pretty sure my right hand still hurts from the high five I gave my dad! I also play Eve Online, and I might have been laughing my ass off and having a great time with my alliance as well ... god I’m a nerd! Went over to my best friend’s house, told her as she has had to suffer through endless bitcoin is great rants, she was like “stfu! No you didn’t! Omfg!”
In the summer of 2010 I was able to sign a block using a Core I7-920, and since it was worth (roughly) 7 cents a bitcoin then, I determined my computer power was better spent doing other stuff and/or not mining. A bit after that I upgraded my 3 drive raid 0 to an SSD and didn’t migrate everything. A couple years back I found a couple wallet.dat files on that SSD but didn’t check the raid array until Friday.
I called my cousin who is a CPA/lawyer, and I told her that I had felt like I had won the lottery and she said to me “every time I hear about bitcoin I think of you, you didn’t win the lottery, you were Into it before the hype, you knew what it was when other people thought it was and still think it is weird. The real thing is you’re lucky because you forgot about it!” This week, I’m going to pay off my house/cacredit cards, put at least 150k into a college fund for my two boys, start looking into paying my taxes and you know pinching myself to make sure I’m not dreaming!
While I should HODL... I have cashed out most of them ... I feel like not having a mortgage payment was a huge plus. And by the way, Bitcoin Cash and the other forks... bless your hearts! The day my two boys were born were the two best days of my life! Merry-f’ing-Christmas!
:edit: Now that I've dumped the wallet and things have been transfered.... not a shit post(?) lol
https://blockchain.info/address/1EfC5cAuagHguQzGdFNebuZS2zsvmWsbPC
:second edit:
I'd be just as skeptical on the internet as some of the people on here so...
Generation Address: 1EfC5cAuagHguQzGdFNebuZS2zsvmWsbPC
Signature: HGifhaImWOrhM/04LcjY94YBFxrba1G3lIRTUQUWPQs3RtEZGNXDnzzp6hQYc+gR4SuJKLDPrhU6xhAfL1TedNs=
Signed Message: https://www.reddit.com/Bitcoin/comments/18qy88/bitcoin_message_signing_and_verification/ 3rd best day!
So you can verify it with something like this:

Pretty sure that verifies it was my wallet :)

The best Tezos Wallets

The best Tezos Wallets
Tezos is a decentralized blockchain that simplifies formal verification, a method that mathematically proves the accuracy of the code controlling transactions. The Tezos blockchain has its own cryptocurrency called Tezos (XTZ), a cryptocurrency with two main functions – a self-administration system and the ability to form launch contracts using its own programming language – Michelson.
If you decide to convert your fiat savings into Tezos or exchange other cryptocurrencies for XTZ, you may have to make a choice among reliable wallets for this. In this article we will look into the best Tezos Wallets so that can help you understand them better.

Hardware Wallets

Hardware wallets are not liable to spam, viruses, phishing attacks, or malicious of the system. Moreover, they provide a high degree of protection to the private keys. Below is the list of hardware wallets that can be used for XTZ.
https://preview.redd.it/j79t9vbgeth31.jpg?width=800&format=pjpg&auto=webp&s=d828387479fc4a2efed4fc857eb9bdf03f9878e9
  • Ledger Nano S
Nano S is a hard wallet from the product line of Ledger, a French manufacturer company. As all other Ledger products, Nano S traditionally looks like a USB flash drive. But this time, you will need to use the USB cable that comes with the wallet to connect to a computer. Ledger Nano S has a chip that is similar with chips on bank cards or biometric passports. Your private key is stored in an isolated environment and is effectively protected. Ledger Nano S also has a screen on it where you can see each transaction made. In case you lose your Nano S wallet, the account can be easily restored on any other Ledger device. Ledger Nano S supports over 20 cryptocurrencies including Tezos (XTZ).
  • Trezor Model T
Trezor T is the flagship model from the well-known Czech manufacturer SatoshiLabs. Model T has a color Touch-Screen display, an SD port and a quantity of supported coins – XTZ is among those coins. When Trezor T is not connected to the computer, it turns off and disconnects from the Internet. Thus, user funds are stored on the device beyond the reach of attackers. Trezor hardware case is ultrasonically soldered, making it difficult to be restored after being damaged.

Web Wallets

Web wallets can be a simple way to get started investing in cryptocurrency. All web wallets can be used right from a browser without the need of downloading software. Beyond that, many of web wallets offer free mobile apps.
  • TezBox Wallet
TezBox was the first GUI released for Tezos. The wallet was developed by the Tezos community and released during the ICO period. TezBox is available for web, desktop and mobile wallets with its user-friendly interface. Users may be assured that all private keys will be stored on their devices safely due to the secured wallet interface. TexBox is the first wallet integrated with hardware wallets Trezor and Ledger Nano S that gives it the increased security.

  • Tezos CLI Wallet
The Tezos CLI wallet can be used by those users who have some coding understanding while it requires the use of command lines. Tezos has mentioned the wallet on its website and has been audited by an independent external security inspector. As the Tezos CLI needs some level of command line knowledge, it can be quite difficult to use.

How to keep your wallet safe

A cryptocurrency wallet can be regarded as a regular wallet with money, but it has advanced features, which increases the level of risk. Simple rules will help prevent the loss of your own savings:
  1. Do not store large amounts for long periods on wallets that do not provide full control. It is better to store large amounts for a long time only in wallets that provide full control over the private key and, accordingly, over digital assets. This will help protect your coins against fraud and cyber attacks.
  2. Encrypt information and back up private keys. In case of reinstalling the PC or the occurrence of force majeure situations, this will help to restore access to the wallet quickly.
  3. Store secret keys on an offline device. It is preferable to use a platform that is not accessible for hacking via the Internet.
  4. Use reliable antivirus software and update it regularly. This will prevent the leakage of personal data that hackers can use to crack passwords.
  5. Register several types of wallets. It will allow you to distribute your funds and use the most suitable wallet depending on the situation.
If you use your Tezos wallet wisely and do not neglect the precautions, the risk of funds loss will be minimized.

The Exhaustive EOS FAQ

The Exhaustive EOS FAQ

 
With the large number of new readers coming to this sub we need to make information easy to access so those readers can make informed decisions. We all know there is an unusually large amount of Fear, Uncertainty and Doubt (FUD) surrounding EOS. Frankly, when clear evidence is provided it’s not that difficult to see EOS for the extremely valuable project it is. This post hopes to begin to put an end to all the misinformation by doing the following:  
  • Giving a clear and concise answer to the most frequently asked questions in regards to EOS.
  • Giving a more in-depth answer for those who want to read more.
  • Allowing readers to make informed decisions by making credible information easy to access.
 
As EOS climbs the ranks we need to recognise there are going to be a lot of skeptical readers coming over and posting their questions. Sometimes they will be irrational, hostile and often just looking for a reaction. We should make it our responsibility to welcome everyone and refrain from responding emotionally to provocative posts, instead providing factual and rational answers.
I will add to this post as and when I can, if you have any ideas or spot any mistakes let me know and I'll get them fixed ASAP. Im planning to add a bit on the team, centralisation and DPOS, governance and EOS VC shortly but please let me hear your suggestions!
 

FAQ

1. How do you registeclaim your EOS tokens before June 2018?

 
Answer courtesy of endless. If you have not done so, you will need to create a new pair of EOS public and private keys and register them with an Ethereum address. This only needs to be done once.
On or around June 1, 2018 all EOS Tokens will become frozen and non-transferable on the Ethereum blockchain. Not long after, I suspect that EOS community members will create a snapshot of token balances that carry over onto a new community generated and selected EOS blockchain. block.one will not be launching EOS blockchains or operating any of their nodes. Additionally, this is a community subreddit unaffiliated in an official capacity with block.one

Did you buy your EOS tokens on an exchange? (Courtesy of IQOptionCoin)
REMEMBER YOU ONLY NEED TO REGISTER YOUR TOKENS IF YOU BOUGHT THEM ON AN EXCHANGE. YOU DON'T NEED TO CLAIM THEM.
  1. Go to the EOS website https://eos.io
  2. Scroll down and select "GET EOS"
  3. Tick all the required boxes and click "Continue"
  4. Scroll down and click "Register"
  5. Select Metamask, MyEtherWallet, or Ethereum Wallet
  6. Follow the guide.
  7. Remember that the reason you need to register your Ethereum ERC-20 address is to include your EOS tokens in order for the balance of your EOS Tokens to be included in the Snapshot if a Snapshot is created, you must register your Ethereum address with an EOS public key. The EOS snapshot will take place prior to the 1 June 2018. After this point your ERC-20 EOS tokens will be frozen. And you will be issued EOS tokens on the EOS blockchain.
So PLEASE REGISTER your Ethereum address NOW, don't forget about it, or plan on doing it some time in the near future.
There are a lot of submissions about this in /eos, so rather than making a new one please reply to this thread with any questions you may have. Don't forget to join the EOS mailing list: https://eos.io/#subscribe and join the EOS community on your platform(s) of choice: Telegram, Discord and/or Facebook.
And remember, if anyone instructs you to transfer ETH to an EOS contract address that doesn't match the address found on https://eos.io you are being scammed.

Official EOS FAQ
 

2. How will the token the ERC-20 EOS tokens be transferred to the native blockchain?

 

Quick answer:

There isn't one! Read the long answer then read it again, registering your Ethereum wallet is mandatory!
 

Long answer:

Within 23 hours after the end of the final period on June 1, 2018 at 22:59:59 UTC, all EOS Tokens will become fixed (ie. frozen) and will become non-transferrable on the Ethereum blockchain.
In order to ensure your tokens are transferred over to the native blockchain you must register your Ethereum address with an EOS public key, if you do not you will lose all your tokens! I am not going to link any tutorials as there are many that can be found by searching Google and YouTube.
block.one is helping with the development of snapshot software that can be used to capture the EOS token balance and registered EOS public key of wallets on the Ethereum blockchain. It is then down to the community to create the snapshot. This snapshot can be used when generating a genesis block for a blockchain implementing eos.io software. block.one will not be launching EOS blockchains or operating any of their nodes.
 
Exchange Support
Some exchanges have announced that they will support the token swap. Although using this method will undoubtedly be much simpler than registering the tokens yourself it also comes with its pitfalls.
  • It is highly likely there are going to be multiple networks running on the eos.io software that use the snapshot. It is highly unlikely that exchanges will support them all.
  • It is highly likely that exchanges will not support airdrops that use the snapshot.
Exchanges that have announced support for the token swap include:

3. What does EOS aim to achieve?

 

Quick answer:

EOS.IO software is aiming to provide a decentralized operating system which can support thousands of industrial scale DApps by enabling vertical and horizontal scaling.
 

Long answer:

EOS.IO is software that introduces a blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications. This is achieved through an operating system-like construct upon which applications can be built. The software provides accounts, authentication, databases, asynchronous communication and the scheduling of applications across multiple CPU cores and/or clusters. The resulting technology is a blockchain architecture that has the potential to scale to millions of transactions per second, eliminates user fees and allows for quick and easy deployment of decentralized applications.

6. Which consensus mechanism does EOS use and what are Block Producers?

 

Quick answer:

Delegated Proof of Stake (DPOS) with Byzantine Fault Tolerance. Block Producers (BPs) produce the blocks of the blockchain and are elected by token holders that vote for them. BPs will earn block rewards for their service, these block rewards come in the form of EOS tokens produced by token inflation.
 

Long answer:

Taken from the EOS.IO Technical White Paper v2:
“EOS.IO software utilizes the only known decentralized consensus algorithm proven capable of meeting the performance requirements of applications on the blockchain, Delegated Proof of Stake (DPOS). Under this algorithm, those who hold tokens on a blockchain adopting the EOS.IO software may select block producers through a continuous approval voting system. Anyone may choose to participate in block production and will be given an opportunity to produce blocks, provided they can persuade token holders to vote for them.
The EOS.IO software enables blocks to be produced exactly every 0.5 second and exactly one producer is authorized to produce a block at any given point in time. If the block is not produced at the scheduled time, then the block for that time slot is skipped. When one or more blocks are skipped, there is a 0.5 or more second gap in the blockchain.
Using the EOS.IO software, blocks are produced in rounds of 126 (6 blocks each, times 21 producers). At the start of each round 21 unique block producers are chosen by preference of votes cast by token holders. The selected producers are scheduled in an order agreed upon by 15 or more producers.
Byzantine Fault Tolerance is added to traditional DPOS by allowing all producers to sign all blocks so long as no producer signs two blocks with the same timestamp or the same block height. Once 15 producers have signed a block the block is deemed irreversible. Any byzantine producer would have to generate cryptographic evidence of their treason by signing two blocks with the same timestamp or blockheight. Under this model a irreversible consensus should be reachable within 1 second."
 

7. How does the voting process work?

 
The voting process will begin once the Block Producer community releases a joint statement ensuring that it is safe to import private keys and vote.
Broadly speaking there will be two methods of voting:
  1. Command Line Interface (CLI) tools
  2. Web portals
EOS Canada has created eosc, a CLI tool that supports Block Producer voting. Other Block Producer candidates such as LibertyBlock are a releasing web portal that will be ready for main net launch. There will be many more options over the coming weeks, please make sure you are always using a service from a trusted entity.
Remember: Do not import your private key until you have seen a joint statement released from at least five Block Producers that you trust which states when it is safe to do so. Ignoring this warning could result in tokens lost.
 

8. What makes EOS a good investment?

 
  • Team - EOS is spearheaded by the visionary that brought us the hugely successful Bitshares and Steem - arguably with two projects already under his belt there is no one more accomplished in the space.
  • Funding - EOS is one of the best funded projects in the space. The block.one team has committed $1B to investing in funds that grow the EOS echo system. EOS VC funds are managed by venture leaders distributed around the world to insure founders in all markets have the ability to work directly with local investors. Incentives such as the EOS hackathon are also in place with $1,500,000 USD in Prizes Across 4 Events.
  • Community Focus - The team is aware that the a projects success depends almost entirely on its adoption. For this reason there has been a huge push to develop a strong world wide community. There is already a surplus number of block producers that have registered their interest and started to ready themselves for the launch and incentives the EOS hackathon are being used to grow the community. A index of projects using EOS can be found at https://eosindex.io/posts.
  • Technical Advantages - See point 9!
 

9. What are the unique selling points of EOS?

 
  • Scaleability
    • Potential to scale to millions of transactions per second
    • Inter-blockchain communication
    • Separates authentication from execution
  • Flexibility
    • Freeze and fix broken applications
    • Generalised role based permissions
    • Web Assembly
  • Usability
    • Elimination of transaction fees
    • True user accounts with usernames, passwords and account recovery (no more having to remember long cryptographic keys)
    • Web toolkit for interface development

10. Is there currently a working product?

 

Quick answer:

This depends entirely on your definition of working product. If a fully featured developer release meets your definition then yes!. Otherwise the public release will be June 2018.
 

Long answer:

EOS differs from other projects in that it aims to deliver a fully featured version of the software on launch. The Dawn 3.0 RC1 feature complete pre-release became available on April 5th. This version has all the features of the final release that is due June 2018. Further development will involve preparing the final system contract which implements all of the staking, voting, and governance mechanics. The common notion that there is no viewable code published is wrong and the initial Dawn 1.0 release has been available from September 14th 2017.
 
EOSIO V1 - June 2nd 2018
Dawn 3.0 RC1 - April 5th 2018

11. EOS is an ERC-20 token, how can it possibly be a competitor to other platforms?

 

Quick answer:

The ERC-20 token is used only for raising funds during the token distribution; all tokens will be transferred to the native blockchain once launched.
 

Long answer:

EOS team has clearly stated their reason for choosing the Ethereum network when they described the rationale behind the ICO model. Specifically, the ICO should be a fair and auditable process, with as little trust required as possible. If you believe that an ICO should be fair, auditable, and trustless, you have no choice but to use a decentralized smart contract blockchain to run the ICO, the largest, and by-far most popular of which is Ethereum. Since EOS is intended to be a major competitor for Ethereum, some have seen this as a hypocritical choice. - Stolen from trogdor on Steam (I couldn’t word it any better myself).

Official EOS FAQ
 

12. Why do the eos.io T&C’s say the ERC-20 token has no value?

 
The EOS T&C’s famously state:
"The EOS Tokens do not have any rights, uses, purpose, attributes, functionalities or features, express or implied, including, without limitation, any uses, purpose, attributes, functionalities or features on the EOS Platform."
 

Quick answer:

This is legal wording to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Most notably Tezos (links below).
 

Long answer:

This all comes down to legal issues. Anyone who’s been into crypto for 5 minuets knows that government bodies such as the Securities and Exchange Commission (SEC) are now paying attention to crypto in a big way. This legal wording is to avoid all the legal complications in this emerging space, block.one do not want to find themselves in a lawsuit as we are seeing with an increasing amount of other ICOs. Many token creators that launched ICOs are now in deep water for selling unregistered securities.
 
A filing from the Tezos lawsuit:
"In sum, Defendants capitalized on the recent enthusiasm for blockchain technology and cryptocurrencies to raise funds through the ICO, illegally sold unqualified and unregistered securities, used a Swiss-based entity in an unsuccessful attempt to evade U.S. securities laws, and are now admittedly engaged in the conversion, selling, and possible dissipation of the proceeds that they collected from the Class through their unregistered offering."
 
To ensure EOS tokens are not classed as a unregistered security block.one has made it clear that they are creating the EOS software only and won’t launching a public blockchain themselves. This task is left down to the community, or more precisely, the Block Producers (BPs). The following disclaimer is seen after posts from block.one:
 
"block.one is a software company and is producing the EOS.IO software as free, open source software. This software may enable those who deploy it to launch a blockchain or decentralized applications with the features described above. block.one will not be launching a public blockchain based on the EOS.IO software. It will be the sole responsibility of third parties and the community and those who wish to become block producers to implement the features and/or provide the services described above as they see fit. block.one does not guarantee that anyone will implement such features or provide such services or that the EOS.IO software will be adopted and deployed in any way.”
 
It is expected that many blockchains using eos.io software will emerge. To ensure DAPPs are created on an ecosystem that aligns with the interests of block.one a $1bn fund will be has been created to incentivise projects to use this blockchain.

13. Why is the token distribution one year long?

 
Official statement from block.one:
“A lot of token distributions only allow a small amount of people to participate. The EOS Token distribution structure was created to provide a sufficient period of time for people to participate if they so choose, as well as give people the opportunity to see the development of the EOS.IO Software prior to making a decision to purchase EOS Tokens.”
 
It is also worth noting that block.one had no knowledge how much the the token distribution would raise as it is determined by the free market and the length of the token distribution is coded into the Ethereum smart contract, which cannot be changed.
 

Sources:

EOS.io FAQ
 

14. Where is the money going from the token distribution?

 

Quick answer:

Funding for the project was raised before EOS was announced, the additional money raised from the token distribution is largely going to fund projects on EOS.
 

Long answer:

A large portion of the money raised is getting put back into the community to incentivise projects using eos.io software. block.one raised all the money they needed to develop the software before the ERC-20 tokens went on sale. There are some conspiracies that block.one are pumping the price of EOS using the funds raised. The good thing about blockchain is you can trace all the transactions, which show nothing of the sort. Not only this but the EOS team are going to have an independent audit after the funding is complete for piece of mind.
 
From eos.io FAQ:
“block.one intends to engage an independent third party auditor who will release an independent audit report providing further assurances that block.one has not purchased EOS Tokens during the EOS Token distribution period or traded EOS Tokens (including using proceeds from the EOS Token distribution for these purposes). This report will be made available to the public on the eos.io website.”

15. Who's using EOS?

 
With 2 months from launch left there is a vibrant community forming around EOS. Some of the most notable projects that EOS software will support are:
A more complete list of EOS projects can be found at eosindex.io.
 

16. Dan left his previous projects, will he leave EOS?

 

Quick answer:

When EOS has been created Dan will move onto creating projects for EOS with block.one.
 

Long answer:

When a blockchain project has gained momentum and a strong community has formed the project takes on a life of its own and the communities often have ideas that differ from the creators. As we have seen with the Bitcoin and Ethereum hark forks you cant pivot a community too much in a different direction, especially if its changing the fundamentals of the blockchain. Instead of acting like a tyrant Dan has let the communities do what they want and gone a different way. Both the Bitshares and Steem were left in a great position and with Dans help turned out to be two of the most successful blockchain projects to date. Some would argue the most successful projects that are actually useable and have a real use case.
What Dan does best is build the architecture and show whats possible. Anyone can then go on to do the upgrades. He is creating EOS to build his future projects upon it. He has stated he loves working at block.one with Brendan and the team and there is far too much momentum behind EOS for him to possibly leave.

17. Is EOS susceptible to DDoS attacks?

 
No one could have better knowledge on this subject than our Block Producer candidates, I have chosen to look to EOS New York for this answer:
"DDoS'ing a block producing is not as simple as knowing their IP address and hitting "go". We have distributed systems engineers in each of our candidate groups that have worked to defend DDoS systems in their careers. Infrastructure can be built in a way to minimize the exposure of the Block Producing node itself and to prevent a DDoS attack. We haven't published our full architecture yet but let's take a look at fellow candidate EOSphere to see what we mean. As for the launch of the network, we are assuming there will be attacks on the network as we launch. It is being built into the network launch plans. I will reach out to our engineers to get a more detailed answer for you. What also must be considered is that there will be 121 total producing and non-producing nodes on the network. To DDoS all 121 which are located all around the world with different security configurations at the exact same time would be a monumental achievement."

18. If block producers can alter code how do we know they will not do so maliciously?

 

Quick answer:

  • Block producers are voted in by stake holders.
  • Changes to the protocol, constitution or other updates are proposed to the community by block producers.
  • Changes takes 2 to 3 months due to the fact block producers must maintain 15/21 approval for a set amount of time while for changes to be processed.
  • To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
 

Long answer:

For this question we must understand the following.
  • Governance and why it is used.
  • The process of upgrading the protocol, constitution & other updates.
  • Dan’s view on open-entry systems built around anonymous participation.
 
Governance
Cryptography can only be used to prove logical consistency. It cannot be used to make subjective judgment calls, determine right or wrong, or even identify truth or falsehood (outside of consistency). We need humans to perform these tasks and therefore we need governance!
Governance is the process by which people in a community:
  1. Reach consensus on subjective matters of collective action that cannot be captured entirely by software algorithms;
  2. Carry out the decisions they reach; and
  3. Alter the governance rules themselves via Constitutional amendments.
Embedded into the EOS.IO software is the election of block producers. Before any change can be made to the blockchain these block producers must approve it. If the block producers refuse to make changes desired by the token holders then they can be voted out. If the block producers make changes without permission of the token holders then all other non-producing full-node validators (exchanges, etc) will reject the change.
 
Upgrade process
The EOS.IO software defines the following process by which the protocol, as defined by the canonical source code and its constitution, can be updated:
  1. Block producers propose a change to the constitution and obtains 15/21 approval.
  2. Block producers maintain 15/21 approval of the new constitution for 30 consecutive days.
  3. All users are required to indicate acceptance of the new constitution as a condition of future transactions being processed.
  4. Block producers adopt changes to the source code to reflect the change in the constitution and propose it to the blockchain using the hash of the new constitution.
  5. Block producers maintain 15/21 approval of the new code for 30 consecutive days.
  6. Changes to the code take effect 7 days later, giving all non-producing full nodes 1 week to upgrade after ratification of the source code.
  7. All nodes that do not upgrade to the new code shut down automatically.
By default, configuration of the EOS.IO software, the process of updating the blockchain to add new features takes 2 to 3 months, while updates to fix non-critical bugs that do not require changes to the constitution can take 1 to 2 months.
 
Open-entry systems built around anonymous participation
To ensure bad actors can be identified and expelled the block.one backed community will not back an open-entry system built around anonymous participation.
Dan's quote:
"The only way to maintain the integrity of a community is for the community to have control over its own composition. This means that open-entry systems built around anonymous participation will have no means expelling bad actors and will eventually succumb to profit-driven corruption. You cannot use stake as a proxy for goodness whether that stake is held in a bond or a shareholder’s vote. Goodness is subjective and it is up to each community to define what values they hold as good and to actively expel people they hold has bad.
The community I want to participate in will expel the rent-seeking vote-buyers and reward those who use their elected broadcasting power for the benefit of all community members rather than special interest groups (such as vote-buyers). I have faith that such a community will be far more competitive in a market competition for mindshare than one that elects vote buyers."

19. What is the most secure way to generate EOS key pairs?

 
Block producer candidates EOS Cafe and EOS New York have come forward to help the community with this topic.
The block producer candidate eosnewyork has kindly posted a tutorial on steemit detailing the steps that need to be taken to generate key pairs using the official code on the EOS.IO Github.
The block producer candidate eoscafe has gone a step further and released an Offline EOS Key Generator application complete with GUI for Windows, Linux & Mac. Not only can this application generate key pairs but it can also validate key pairs and resolve public keys from private keys. This application has also been vouched for by EOS New York

Best General RenVM Questions | August 2019

Best General RenVM Questions of August 2019

These questions are sourced directly from Telegram, other monthly FAQ can be found here: https://docs.renproject.io/darknodes/community/monthly-community-faq
Q: So RenVM is essentially a BFT protocol (with 1/3 malicious nodes) that does ECDSA threshold key generation and signing? Is that right?
A: Yes, that's exactly what we have! We are exploring getting this to 1/2 and are confident it is possible, but the current implementation on Testnet is 1/3. Just today we also pushed an update that doubled the speed (and halved the bandwidth) of the sMPC signing algorithm.

Q: Have any tests been done on the speed of Interoperability?
A: The Testnet demo is live and open to the public, have a play with it and let us know about your experience (including speed). We have done some preliminary profiling; numbers look good so far. Fast enough for a single shard to keep up with Bitcoin.
The next version of RZL sMPC is under development and will introduce pre-computations that significantly increase the peak performance of RenVM from 10 TPS to over 100 TPS (these numbers are based on our initial conservative estimates).

Q: Currently, we see a quick performance of the swaps. When migrating to the mainnet (considering there will be real mainnet of say 250 Darknodes and real BTC, ETH, etc.) will it affect the speed?
A: Speed is a complex issue when it comes to RenVM. I'll try and break it down:
The biggest concern for speed is that RenVM needs to wait for a transaction to be confirmed on one chain before shifting the tokens to another chain. When working with Bitcoin this can take hours. -So latency is unavoidable (think of latency as how long a tunnel is) -So what about throughput (how wide the tunnel is)?
First, how to solve the latency problem. Well, we cannot actually solve it because we cannot change Bitcoin. But we can work around it by using "Universal Interoperability." In this model, a third party takes on the confirmation risk. While RenVM waits for the confirmation of a transaction on Bitcoin, the third party steps in and fulfills the Ethereum side of the transaction with BTC that has already been shifted previously. When the Bitcoin transaction is finally confirmed, the third party is refunded using the newly shifted BTC. This means the third party is taking on risk (the Bitcoin transaction may be shuffled away), so they charge a fee to cover this + their services. This means that the shift can be almost instant, and the only thing we need to worry about is throughput.
We believe we can get 10 TPS throughput, which is more than Bitcoin, so throughput isn't a problem (we only need to be as fast as Bitcoin). For other chains that are faster, we can introduce multiple shards. If one shard can do 10 TPS, then 10 shards can do 100 TPS.
I've described this process with Bitcoin, but it works for any pair of chains. Also, the third party cannot be guaranteed to step in (maybe they don't want to take the risk today) but if they do not, then the transaction will still go through but just at the slower speed. If the third party does step in, they're guaranteed to be refunded. So the introduction of "Universal Interoperability" does not introduce any central trust into the system.

Q: So Universal Interoperability is a partially centralized thing?
A: No because any third party can step in and provide the service. Further, the processes involved are all handled by smart contracts.

Q: Has there been a discussion of security in terms of sharding? Getting 1/3 stake and compromising a shard is obviously much easier than compromising the network, what's everyone's thoughts on that?
A: Yes there has; once you move to a sharding model, the risk of an attacker gaining control of a shard becomes a probabilistic problem rather than an absolute one (for example if you're sampling with replacement, in theory, a single attacker can corrupt the whole network).
Let's say an attacker owns enough of the network to have a 2^-1 chance of corrupting a shard (expected time to attack = ~2 days). If you are using a 20/20 multi-sig, where each shard controls one signature, then the chance of corrupting enough shards becomes 2^-20 (expected time to attack = ~2800 years).
In line with this example, the shard could be around N=24 (which would have a corruption chance of ~0.56) so each shard can be very fast (and shards would be running in parallel). Obviously we want to avoid multisigs (they're expensive and not all blockchains can support them) but this is mostly an example of the larger concept: requiring multiple shards to work together.

Q: Just got curious if the bug-fixing and developing has been overwhelming since the release of testnet? How do you feel it's been so far?
A: I wouldn't say overwhelming. It's definitely keeping us busy. Finding bugs and fixing them is actually very satisfying work; it reduces stress by increasing confidence, and this helps improve motivation and productivity.
It's also good to be able to revisit parts of the system and go about perfecting them. Often in software development, there is the adage "never optimize early". Well, the time has finally come to optimize (not just performance, but design, safety, etc.). Everyone wants the thing they build to be perfect, and being able to make that the focus is an awesome feeling.

Q: Is there a reason for having private repos?
A: It's important for the success of the network to maintain a competitive advantage, and important to avoid "day zero" bugs from people that find them but don't report (in the hopes to take advantage). We'll be getting the code (and our maths) reviewed and audited, and probably show it to first adopting groups so they can verify it themselves, and as Mainnet grows we will open-source everything, along with a Transperency Plan that outlines when and how repos will be open-sourced.

Q: My Darknodes still show the old command center. How do I view them on the new one?
A: The new Command Center is for RenVM specifically (and it's only viewable on RenVM Testnet); once we switch Darknodes over to the RenVM network, they will utilize the new Command Center.
To play around with it, put your MetaMask on Kovan Test Network. A video that a community member created can be found here: https://twitter.com/RenIsLyfe/status/1166091169853579265?s=20

Q: Digital Ocean (DO) sent me a message saying my VPS would be down for maintenance, is this an issue?
A: Nope, this is just part and parcel of using a VPS. From time to time, they need to do maintenance. They will inform you if you need to take action.
This is a real-world example of why it's crazy to expect a decentralized network to have all participants online all the time, and why you cannot "incentivize" being online by punishing being offline. It's unavoidable even when there are entire expert teams with years of experience on the job. The more nodes you have, the more likely any one of them is to experience an issue like this at any one time.
Your REN is not at risk if your Darknode does go offline. It is also unlikely that a Darknode that is offline due to these kinds of circumstances will remain offline long enough to be forced out of the network.

Q: Will the community darknodes be partaking in the RenVM Testnet, or are you using your own nodes to test it out, or is it a gradual deploy?
A: The team has about 24 Testnet Darknodes that power it. We may open these Testnet nodes up to a few groups in the Working Group, but no public participation of Testnet Darknodes will be pursued at this time.

Q: A couple of questions for the team: 1) Bonded REN value informs how much value can be securely shifted through RenVM at any given time. If bonded value drops below the threshold, are there any risks beyond incentive to collude which arise? is there any liquidation risk ala TBTCsigners? 2) Does RenVM enforce any time floors/ceilings on shifting/locking tokens? I assume anything like that would be enforced by a third party like Compound?
A: 1. There are collusion risks but we plan to mitigate this by having Darknodes able to "tell on each other" so if you are colluding with someone that you don't trust 100% you risk losing your bond so attacks only really make sense if you own all the colluding Darknodes (which, by definition, isn't really collusion it's buying up a bunch of REN). There is no liquidation risk. This is one key reason why we bond using REN, not another token; the "value of REN" is tied only to the use of RenVM. The safety of RenVM is predicated on the use of RenVM. RenVM is used = RenVM is safe
  1. No time ceilings. We've been having discussions about how to keep Darknode well incentivized to maintain long-term deposits, but (a) most of RenVM's UX is built around handling the native token, not a wrapped version of it (how is a BTC maxi going to get a hold of ETH to use their ERC20 BTC?), and (b) payments will be paid out over time to RenVM not instantly so this creates a more stable income for the Darknodes instead of large but infrequent lumps of pay, (c) we got another trick up our sleeve that I'll be adding to the GitHub any day now, (d) if you have ideas about how to incentive Darknodes to maintain BTC that is being deposited long-term, please feel free to let us know!

Q: Has there been a pattern established where third-parties could pay the gas for the eth transactions needed during shifting? For instance, would it be straightforward for an app dev to pay the gas for the user but add a small additional fee onto the RenVM transaction? They would pay the gas in ETH for the user in exchange for that value collected in BTC or zBTC?
A: This is going to be very straightforward for devs. We are designing examples as we speak to set the standard for doing this and therefore make integration as easy as possible.

Q: Can a RenVM gateway addresses be reused? As in if a user creates a gateway address for 0.1 BTC, can they send exactly 0.1 BTC that address, mint zBTC, and then repeat that process again without creating a new gateway?
A: Currently no, a gateway can only be used once; but we are in the process of creating that feature and it should be ready within the next month or so.

Q: What’s the best way to set up a Darknode if I only have Microsoft?
A: We do not formally support a Windows CLI as of right now, but we are adding Windows CLI support prior to Mainnet, so please do stay tuned.

Creating and address and private key via the command line

I installed the Bitcoin Core a few weeks ago (still haven't managed to fully synchronize) with a view to learning a bit more about the technical side of Bitcoin.
Yesterday I read a post which said that (once you had installed the Core) you could create a Bitcoin address via the command line, so I thought I would try it out.
I found it difficult to find a bare bones explanation of the minimum required to get it working so, having finally gotten it working, I though I would post mine here.
What you will need:
1) A .bat file containing the following:
"C:\Program Files\Bitcoin\daemon\bitcoind.exe" -daemon 
2) A .bat file containing the following:
echo off for /f "delims=" %%i in ('"C:\Program Files\Bitcoin\daemon\bitcoin-cli.exe" getnewaddress') do set outAddress=%%i echo "Address = " %outAddress% for /f "delims=" %%i in ('"C:\Program Files\Bitcoin\daemon\bitcoin-cli.exe" dumpprivkey %outAddress%') do set outKey=%%i echo "Key = " %outKey% pause 
3) A text file called bitcoin.conf with the following contents:
server=1 rpcuser=pick_your_own_user rpcpassword=pick_your_own_password rpctimeout=30 rpcport=8332 rpcconnect=127.0.0.1 noirc=0 minimizetotray=0 
The steps are:
...and that should be it
If bitcoin.conf already exists, you should be able to skip step 2 and just do steps 3 and 4.
Obviously you will need to change the paths to match your own setup (and put your own user and password in the .conf file - they can be anything, but should be unique)
Hope this helps somebody get up and running quickly.

Fun out-of-the-box commands for Windows 10

No WSL required; these commands work in the command prompt without any setup whatsoever:
 finger [email protected] - a nice meteogram (also works in XP/Vista/7/8 by default) ssh redditbox.us - a CLI Reddit client ssh sshtron.zachlatta.com - a multiplayer Tron clone ssh netris.rocketnine.space - multiplayer tetris ssh [email protected] - a fun roguelike game ssh [email protected] -p 2222 - guess free minesweeper; Pass: play ssh chat.shazow.net - a chat room full of strangers ssh [email protected] - play various games including checkers ssh brow.sh - a CLI internet browser (I haven't been able to click on things unless I'm running it on macOS or Linux) curl https://tgftp.nws.noaa.gov/data/observations/metastations/KATL.TXT - METAR, replace KATL with any other ICAO curl parrot.live - a cute parrot animation curl https://icanhazdadjoke.com - shitty jokes curl pseudorandom.name - generates a random name curl dict://dict.org/d:computer - dictionary curl 12.io/ip - fetches your IP curl ipinfo.io/8.8.8.8 - fetches your geolocation 
If you enter “reg add HKCU\Console /v VirtualTerminalLevel /t REG_DWORD /d 1” then ANSI escape sequences will format correctly, which allows the following additional commands to output correctly: (and it colors the parrot)
 curl wttr.in/moon - see the current phase of the moon curl http://getnews.tech - see the top headlines curl cheat.sh - the home display for sub commands to programming resources curl cmc.rjldev.com - get coinmarketcap top 100 cryptocurrencies 
If you navigate to "Control panel -> Regional settings -> Administrative tab-> Change system locale" and activate "Beta: Use Unicode UTF-8 for worldwide language support" the following additional curl commands will also output correctly, IF you're using an advanced command line application such as Cmder or the new Windows Terminal:
 curl rate.sx - bitcoin prices curl rate.sx/[email protected] - bitcoin trend graph curl qrenco.de/STRING - replace string and generate a QR code curl wttr.in/cityname - get the weather forecast for your city curl v2.wttr.in/cityname - get a graphical weather forecast for your city 
These commands are now possible on Windows 10 since support for finger, ssh, and curl was added and enabled by default. You can setup a doskey for cmd aliases. Note that curl commands in PowerShell must be entered as curl.exe. There are also some fun telnet game servers as well as the Star Wars Episode IV ASCII movie (alternatively you can watch it with Netcat, "nc towel.blinkenlights.nl 23" which can be installed with Scoop, also try "nc rya.nc 1987") but the telnet feature must be manually enabled (run "dism /online /Enable-Feature /FeatureName:TelnetClient") and its known for being an insecure protocol. If you still choose to enable it, here's a bitcoin ticker and some fun game servers:
 telnet ticker.bitcointicker.co 10080 telnet freechess.org telnet aardmud.org telnet telehack.com telnet milek7.gq telnet mud.darkerrealms.org 2000 
I'd recommend Scoop as well as Pip (bundled with Python installation, which can be installed through Scoop and includes twitter and term2048) if you enjoyed these commands and would like more. Let me know if there's any commands that I should add to this list, I found most of them here!

MiningPoolHub/AwesomeMiner/MultiMinningPool FAQ

Hello everyone,
As some of you have probably noticed I have been taking the time to try my best to help some of you answer some questions.
 
However there has been a lot of repeat questions lately so hopefully this will help. I will continue to update this as we go, please check back if you have any questions as I will try to update this frequently
 
 
If you have a question you do not see covered please feel free to comment and I'll add it and try to answer it. I have added a unresolved to the beginning of this FAQ. I will number them below. Please comment below with the answer, to help me identify which question you are answering please add. UR#(x) to your comment as well, with x being the number of the unresolved question.
 
 
Before we start I will get my disclaimer out of the way.
I do not work with/for any of the developers of these programs. I do not have all the answers. Some of these are my best guess, others may be wrong or may have a better solution than the one I give. Please feel free to correct me if this is the case and I will edit as we go.
 
 
Set-up
We have two text guides here by waffleflops one for awesome miner and one for multi mining pool.
We also have a YouTube video guide by razorseal
 
YouTube Video Guide: Here
Awesome Miner(AM): Text Tutorial
MultiPoolMiner(MPM): Text Tutorial
 
 
So which one should I use?
It seems like it depends on what you want from the program, Awesome Miner is more like Nicehash in the way it looks but can be a little more complicated. MPM is pretty simple but it has less customization for those not familiar with programming.
 
NX18: "I find MPM to be better. No stability issues, no funky windows service always running in the background, and it checks MPH for best coin to mine whereas AM checks whattomine.com and they differ significantly sometimes."
 
MPM also has a minimum dev fee of 10 minutes per day (even if you set donate to 0) whereas AM does not seem to have dev fees. Both I believe have fees included that go to the devs of the miner programs themselves. However these fees for the miner devs will be attached whether you use MPM/AM or solo miner with the miner dev programs anyway.
 
 
Unresolved Questions
 
1. Anyone have solutions on crashing or very low Hashrates in sgminers with AMD GPU's in Awesome Miner?
2. Why is Lyra2Z using only 40% power from my GPU (GTX980ti)? Where/how can it tweak the settings?
I believe this is having to do with Awesome Miner 3.I did not see it asked or posted but I am curious if there's a way to bench all gpus. Instead of selecting gpu 0 and benching, waiting until its done and moving on to gpu 1 and so on. I have 8 nvidia gpus, just wondering if there's a way to auto bench all of them in a row so I can walk away and go to bed, be done I'm the middle of the night.
 
 
General MPH Questions
 
1.Hashrate is not the same on my miner as it is on the dashboard?
From MPH: "Hashrate showing on site is just an estimated value. Pool doesn't know about miner very much. It just collects certain "shares" which is some piece of hash that satisfies certain conditions. So don't worry, it's all about probability thing. Your hashrate on site can go up and down time to time."
There is some luck involved when mining in pools it is like playing the lottery. NiceHash paid at a certain rate because you were not mining coins and getting paid you were getting paid for the hash you are providing.
 
2. Balances on MPH what are the brackets?
The brackets are coins that have not yet been confirmed enough times on the blockchain. Any coins not in brackets have been confirmed.
 
3. How long will it take for my coins to show up, transfer to and from the exchange, be credited to my auto exchange coin?
 
I have been seeing a lot of questions about this so I made a flowchart which you can view Here
 
Short Answer: It depends could be minutes could be days
Long Answer: It has to be exchanged first and then placed in auto-exchange balance balance.
So you mine coin
Coin credited but unconfirmed (this can take time depending on coin)
Coin is confirmed and credited for auto exchange.
Coin is then placed on exchange. So again has to be transferred and again has to be confirmed but on exchange side.
Coin is most likely converted into btc then into auto-exchange coin at exchange.
Then auto-exchange coin is sent back to your balance on mph. So again has to be confirmed before appearing.
Depending on how fast a coin is confirmed will depend on how fast it appears in your balance.
If you stopped mining today it your balance most likely continue to grow over time.
However if you continue to mine it should in theory catch up and you will see you balance grow at a semi if not expected rate.
 
Supplemental:Forgive me if I'm misunderstanding, but this should mean it changes column, not disappears from balance entirely, no?
You will not know exact balance until it is sent back over from the exchange. This is because of the fact that you are exchanging the coins against one another. If one coin is up and one is down you could be losing or gaining value depending on the situation. This is why it seems that coins on the exchange disappear without your auto-exchange coins balance going up right away. Reference question 8 for more info
 
4. What is the best coin to auto-exchange?
This depends, just remember BTC has high transaction fees and can take some time to confirm. You will want to have a good amount of BTC before moving to your wallet to minimize the amount you lose to transaction fees.
I personally use LTC, it is quick and transaction fees are low compared to BTC but can still be exchanged for fiat on coinbase.
At the time of writing this, if you move BTC from MPH you will be charged a $4.96 fee, if you move LTC the fee to move to your wallet is $0.19
 
5. Can I hold on to certain coins instead of auto-exchanging them?
Yes, just go to auto exchange on MPH and switch off the coin you do not want to auto exchange.
 
6. This dashboard sucks! Why do they not have a one page dashboard?
Good news it is in the works, improvements are on the way so no need to keep posting about it!
 
7. Why is my coin not being exchanged?
Two possible reasons A)On balances page it says "coins that don't have enough volume on exchange for a certain amount of time will not be auto exchanged to desired coin. These coins may be sent back as original coin or btc."
B)On auto-exchange page. Mph accumulates coins so that they can be efficiently converted at the exchange. If a coins pool has not mined a certain amount it will not be sent over until it reaches the set number. It seems like it is transferred over to the exchange as one large amount instead of small amounts.
 
8. AwesomeMiner said I was going to make $X.XX dollars and when auto-exchange coins came in I made less than it said!
Couple things, do not take to heart the exact number it gives you. It is not exact remember it is like a lottery.
Remember your coins at first will trickle in over time but the longer you mine it will begin to average out.
Remember you are exchanging coins for you auto-exchange coin this means if there is a decrease or increase between them you could gain more or less.
Example if you mine VTC and auto-exchange into LTC.
You send VTC to auto-exchange it will most likely be converted into BTC first. If BTC is having a good day that day and has increased in price by 30% and VTC has not grown well that day you will be trading your VTC at a loss.
Then this same situation will happen again when converting the BTC to LTC.
So again a bit of a lottery you may gain or lose some of your mined coins value depending on the exchange rate between the coins at the time.
 
9. Add more Cryptonight coins please.
They are apparently working on adding new coins like Electroneum.
 
10. Why can't I auto-exchange BTC?
My theory is that it is because BTC is not mined on MPH, remember the coins are sent to the exchange when they hit a certain amount in order to make it efficient. Because BTC is not mined on MPH it would not be efficient to exchange BTC to other coins once it has been credited to your account.
 
11. Do I need a wallet for each coin I mine? How do I set-up a wallet?
No, only the coin(s) you want to get paid in. Click on coins pool on MPH and you will see a wallet option Add the correct address for each coin you want to be paid in, note you cannot use another coins address or you risk losing your coins. For example you should not put your Bitcoin address into your Litecoin wallet address section.
 
12. My wallet address keeps on changing, do I need to keep updating my wallet address?
Take from Coinbase: This is done to protect your privacy, so that a third-party can not view all other transactions associated with your account simply by using a blockchain explorer to look-up an address they know to be yours.
All addresses that have been generated for your account will remain associated with your account forever. They are safe to re-use to receive future payments, but for the prior stated reasons, we recommend using a unique address for all transactions.
 
13.Is there a easy way I can track my Profits/Hashrate/Workers?
Yes credit to JaymZZZ Click Here
 
14. I click on manage wallet from the balances menu and enter my account number, I get the error saying Failed to update your account: Invalid coin address.
Make sure you are adding the address to the correct coin. A bitcoin address for example should only be added to the bitcoin wallet, it should not be added to any other wallet. (Reference question 11)
 
15. Is there a fee for auto-exchange?
Yes 0.2%
 
 
Awesome Miner
 
1. I do not want to mine that algo, I turn it off but it still mines it!
Go to online services, edit, change profit switching from yes to no
 
2. Why is it mining something less profitable?
Make sure you go to tools and then benchmark Make sure you right click and save hashrate occasionally it will improve your profit switching over time.
 
3. I can't get the miner to run?
Did you exclude it from anti-virus?
You may need to reinstall.
Uninstall
then in search bar type in %localappdata%\awesomeminer (delete this folder)
Type in %appdata% go to awesome miner folder and delete this one as well
Reinstall awesomeminer
Do not run aweseomminer
Go to anti-virus and exclude all folders with awesomeminer (including the ones in the local and appdata folders)
 
4. How do i delete a Miner?

5. Can I do anything to make improvements?
puch0021:You can use VertMiner (which is what is used by OCM) to increase your hash rate compared to AwesomeMiner's default CCminer. You have to choose it for Lyra instead of CC miner. See: http://www.awesomeminer.com/help/managedsoftware.aspx Download Vertminer and extract software. Go to awesomeminer's options -> managed software -> add new user defined mining software: Type in VertMiner for description, full compatibility mode, and compatible software as CCminer. Everything in the algorithm should be disabled expect Lyra2ReV2 which should be enabled. Double click in under defined command line argument and add lyra2v2 as text. Click ok. Go to profit profiles in awesome miner. Select nvidia GPU and edit. In the mining software list there should be a new VertMiner entry. Check this box to enable it. Then click configure and then under path click browse. Click local. Select the Vertminer folder you previously made. Now whenever lyra is called for, vertminer should be used. If you try to bench mark with this enabled, it will fail but it works for mining. You can then use your mining results to manually edit your profit profile value for Lyra2REv2 (that was otherwise has the old value for ccminer.) On my 1060 it went from 21 to 22.8. Keep in mind vertminer takes 2% dev fees but it still works out to be faster than cc miner. let me know if this was any help!
I used one click miners vertminer since it was already installed.
 
6. Whenever Awesome Miner starts on a new algo and opens new instances of the CLI miner application/s, the window steal the focus from whatever you're doing. Anyone else super annoyed by this? Anyone know of a way to prevent this?
Stop mining, click more, properties, environment, console window mode, hide window, start mining again.
 
 
MultiPoolMiner (MPM)
 
1. I see a yellow stripe wich says multipoolminer is between 7% and 17% more profitable, which is nice. under this strip I see 2 lines with miner, BTC and Euro. (in my case) which of those btc values end up on your miningpoolhub balance? or both?
NX18:" Neither. Those values are best guesses by that script, hence why beside the dollar figure it shows the +/- variance which sometimes is really high like 25%, meaning that scripts best guess could be wrong by that much"
It is showing the 2nd best, If it is not the best at the time it will not show that text and just give you the comparison.
 
2. It keeps say NiceHash API failed what should I do? You can ignore it or as chillfisch points out that you can just delete the nicehash folder to get rid of this warning.

Vertnode - An automated solution for installing Vertcoin node(s) on Single Board Computers

Hello Vertcoin Community,
Eager to contribute to the Vertcoin Community I began creating step by step walkthrough guides on how to get a Vertcoin node up and running on a Raspberry Pi, Raspberry Pi Zero and Intel NUC. Along with information to get a Vertcoin node up and running was also optional steps to install p2pool-vtc.
I decided that while this step by step guide might be helpful to a few, a setup script may prove to be useful to a wider range of people. I have this script to a point where I think it may be productive to share with a bigger audience, for those who are brave and have this hardware sitting around or like to tinker with projects; I invite you to test this setup script if you are interested, if you run into errors any sort of verbose console output of the error proves to be extremely helpful in troubleshooting.
The script was designed to produce a “headless” server... meaning we will not be using a GUI to configure Vertcoin or check to see how things are running. In fact, once the server is set up, you will only interact with it using command line calls over SSH. The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Why run a headless node on a Single Board Computer?
The idea is to have this full node be simple, low-power, with optimized memory usage and something that “just runs” in your basement, closet, etc.
Required: USB Flash Drive 6GB - 32GB
Please note that the script was designed for Single Board Computers first and looks for an accessible USB Flash Drive to use for storing the blockchain and swap file, as constant writing to a microSD can degrade the health of the microSD.
Supports

Hardware

All of the hardware listed above is hardware that I have personally tested / am testing on myself. The plan is to continue expanding my arsenal of single board computers and continue to add support for more hardware to ensure as much compatibility as possible.
Functionality
It is worth noting that LIT can be ran with multiple configurations, the ones displayed in the Post Installation Report reflect values that run LIT with the Vertcoin Mainnet. Please be aware that the Vertcoin Testnet chain has not been mined 100% of the time in the past, if you make transactions on the Vertcoin testnet that do not go through it is likely because the chain has stopped being mined.
BE CAREFUL WITH YOUR COINS, ONLY TEST WITH WHAT YOU ARE OKAY WITH LOSING IF YOU USE THE MAINNET.

I've included some documentation on LIT I created which includes information I found to be useful: https://github.com/e-corp-sam-sepiol/vertnode/blob/mastedocs/lit.md

Vertnode | Automated Vertcoin Node Installation Script

https://github.com/e-corp-sam-sepiol/vertnode

Recommended: Use Etcher to install the chosen OS to your microSD card / USB flash drive.

If you intend on installing Ubuntu Server 16.04 to your Intel NUC please use Etcher to install the .iso to your USB flash drive.
https://etcher.io/
PLEASE NOTE THIS SCRIPT MAY GIVE AN ERROR. THIS IS THE NATURE OF TESTING. PLEASE REPORT YOUR ERRORS IF YOU WANT THEM TO BE FIXED/RESOLVED. THANK YOU FOR BETTERING THE DEVELOPMENT OF THIS SCRIPT.

Ubuntu Server 16.04 Setup Details

You can use different clients to ssh into your node. One option is using PuTTY or Git Bash on Windows which is included in the desktop version of Git. If you are using Linux you can simply open a new terminal window and ssh to the IP address of your node (hardware you intend installing the Vertcoin node on).
You will need to know the IP address of your node, this can be found on your router page.
ssh 192.168.1.5 -l pi For example, this command uses ssh to login to 192.168.1.5 using the -l login name of pi. The IP address of your node will likely be different for you, in this example I am logging into a Raspberry Pi which has a default login name of pi.
A brief list of commands that can be used to check on the Vertcoin node status:
vertcoin-cli getblockchaininfo | Grab information about your blockchain
vertcoin-cli getblockcount | Grab the current count of blocks on your node
vertcoin-cli getconnectioncount | Grab the current count of connections to your node. A number of connections larger than 8 means that you have incoming connections to your node. The default settings are to make 8 outgoing connections. If you want incoming connections please port forward your Raspberry Pi in your Router settings page.
vertcoin-cli getpeerinfo | Grab the information about the peers you have connected to / are connected to
vertcoin-cli getnettotals | Grab network data, how much downloaded/upload displayed in bytes
tail -f ~/.vertcoin/debug.log | Output the latest lines in the Vertcoin debug.log to see verbose information about the Vertcoin daemon (ctrl+c to stop)
Thank you to all who have helped me and inspired me thus far, @b17z, @jamesl22, @vertcoinmarketingteam, @canen, @flakfired, @etang600, @BDF, @tucker178, @Xer0
This work is dedicated to the users of Vertcoin, thank you for making this possible.
7/20/2018 Thank you @CommodoreAmiga for the incredibly generous tip <3
