Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

How to Upgrade?

Windows
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer.
OSX
If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

Happy Halloween! Audit Statuses of Canadian Cryptocurrency Exchanges

Halloween is a wonderful time of year!
Businesses and consumers alike dress up, children go door to door naively asking strangers for candy, and everyone parties celebrating things like death and evil.
In the spirit of Halloween storytelling, let me tell you a scary story.
There once was a Canadian cryptocurrency exchange. It had one of the simplest user interfaces, the CEO was well known in person and trusted throughout the country for over half a decade, and it had several deposit and withdrawal methods. It was the first to register as a money services business and for much of its history, it was one of the most legally compliant exchanges. It even looked to be headed for public listing on the TSX. The exchange operated for 6 years, assuring users that all funds “are stored in cold storage, using some of the most secure cryptographic procedures possible.” Unfortunately, while we celebrate Halloween by dressing up and wearing masks once a year, the wonderful people who brought us this exchange played “dress up” for over half a decade and time will only tell if there are any more “masks” to come off in this story.
There’s no better or more fitting time to explore one of the darkest realities of the Canadian cryptocurrency space - exactly what is backing any of the cryptocurrency on Canadian exchanges. It’s easy to lose sight that there are real people behind these funds. Most people spend most waking hours working for their money. It literally is their lives. Impacts to victims are not just financial, but psychological and social as well. Victims of exchange fraud go through depression, anxiety, and trauma. They lose their trust and faith in humanity. They withdraw from friends and family in shame and humility.
In the spirit of exploring dark and evil things, let’s examine exactly what evidence there is that any of your crypto is backed on any Canadian exchange. This is a continuation of research I’ve been working on since May/June. I hope it will be enlightening and help you better protect your funds that you worked hard for.

I’ve done a detailed analysis of all Canadian exchanges I could find that handle any sort of custody of funds, and grouped them into 3 categories:

Non-Audited Exchanges (“trust us, we haven't spent your money, we promise")

Bitvo - The service “utilizes a proprietary cold storage solution”. Proprietary, as in, definitely better than established non-proprietary solutions. If you can’t withdraw, they “will credit your account for [their] withdrawal fee”. They’re not an MSB that I could find, nor are they audited.
Coinfield - MSB. No audit. Luckily it’s the "most secure trading platform in Canada" - though apparently not the other 150+ countries, including Estonia where they’re based. No matter which country you pick, the “Security” page still says "most secure trading platform in Canada".
Coinsmart - MSB. Not sure what "[i]ndustry leading cold storage" is, but luckily they’re so "accountable to [their] clients, community and to each other" and "committed to being open and honest" that they don’t need any audit.
Coinut - MSB. Also "the most secure cryptocurrency exchange platform". In addition to not using multi-sig and "not us[ing] USB drives, as the online computer may be infected with virus", they also don’t use audits.
Einstein - You can get “your money deposited and withdrawn faster than any other exchange”. As one customer said "With so many hacks and exit scams, it gives me confidence knowing Einstein is backed by hard-working people just like me." Just check the user experience on their subreddit from their "220,000+ satisfied customers".
EZ-BTC - As they said, “All your coins are kept in cold storage. They’re safe.” They have “strong security”. The supposed presence of physical ATMs was one of the strategies to build customer confidence and they promised 9% annual return on stored funds.
NDAX - MSB. Luckily also “Canada’s most secure trading platform” with "fast withdrawals". I couldn’t find any audit but at least there’s a full page risk disclosure and disclaimer. You can sleep peacefully knowing that they’re legally protected.
Netcoins - MSB. The best assurance I could find of solvency is that they “can process large transactions”. Although they don’t waste time with audits or links at the bottom of their website, apparently “[a]ll transactions happen quickly and securely” “within the same day”.
Newton - MSB. “No-fees”! Your funds are stored in the "professional custody" of Balance, which doesn’t appear to be a registered MSB. I couldn't find any audit of the funds but they "audit [their] policies and controls". They "publish the reports", but I couldn't find any reports. Simply storing funds somewhere else doesn’t give any assurance they cover customer balances.
QuadrigaCX - Operated since 2013, with “vast cryptocurrency reserves” right up to the end. "Bitcoins that are funded in QuadrigaCX are stored in cold storage, using some of the most secure cryptographic procedures possible." Their "cryptographic" procedures are so secure that nobody can access any funds, even now!
Shakepay - MSB. Many will trust the raccoon mascot promising “commission-free” trading. No audit found but the “majority of all digital assets on Shakepay are stored securely offline”. Whatever this means, it’s good to know that up to half might not be.

Audited Exchanges ("so and so swears we didn't spend your money, you can trust them, we showed them once before")

Bitbuy - MSB
Coinberry - MSB
Coinsquare - MSB
Kraken - Not a registered MSB in Canada (that I could find)

Proof of Reserves ("here's your money, right here right now on the blockchain, and here's a proof that we included your balance in that total")

Rather than depend on outdated audits (or lack thereof), it’s actually possible to use the blockchain and cryptography to enable a public real-time audit. This can give assurance to every customer that their balances are fully backed. Giving everyone the ability to check the integrity of balances will keep us all safer. It immediately exposes any fraud, and in most major hacking cases there was advanced hacking that went unnoticed ranging from months (Bitgrail), or years (Mt. Gox). Having an aware public reduces the number of people trading on fraudulent exchanges, and can pressure the exchange to shut down trading or resolve the hack faster, so less funds are permanently lost.
To help explain exactly what this is and how it works, I’ve started a detailed tutorial. I did not come up with this algorithm - it was created in 2014 by a guy named Gregory Maxwell. Sometimes cryptography can be hard to understand. Hopefully this tutorial is simple:

< < Take Our Proof of Reserves Tutorial > >


Given what can often be at stake, I had hoped that maybe one of the “audited” exchanges might embrace Proof of Reserves. Sadly I haven’t had any such luck.
Bitbuy:
Coinberry:
Kraken:
As such, the bottom line is that present exchanges don’t want to share public keys and offer the kind of transparency which is necessary to enable customers to know their funds are backed. Attempting to get answers doesn’t reveal them, and I’m left with an unnerving silence not unlike the end of Halloween night, like I’m asking questions nobody should ask.

Having spent the last 8 months of my life watching and being part of a large group of people suffer through a grueling bankruptcy, where we’ll be “lucky” to only lose 90% of our funds, I want this fixed. I don’t want to live in a reality where fraud can happen just buying/selling on the largest and most trusted exchanges. Especially now that I’ve learned blockchain provides the capability for even greater transparency and a level of public audit far beyond even what's possible with fiat.
If you feel the same way, I invite you to join Quadriga Initiative, where we are fighting for a Proof of Reserves future and also enabling businesses to help Quadriga victims with an innovative token recovery project. Every sign-up helps us reach our goal and launch the project!

If any information in this post is incorrect, please let me know so I can fix it! Thanks! I’m happy to update the audit status of any exchange given reasonable evidence, or provide a review of any other custodial exchange I might have missed.

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.

  • 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.

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.

Best Ethereum Wallets

Best Ethereum Wallets
When you start using cryptocurrency the number one problem is to find a secure wallet. In this article, we will introduce the most popular Ethereum wallets.

Hardware Wallets

We start with hardware wallets. These wallets provide offline storage for cryptocurrency. This kind of Ethereum wallet is considered to be the most secure.
https://preview.redd.it/86nocaff0mh31.jpg?width=720&format=pjpg&auto=webp&s=7a6d4e9a4ef9945eec416583d487e5553c4377e9

  • Trezor
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm.
On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.

  • Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation.
The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.

  • KeepKey
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough.
It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome.
Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.

Web Wallets

The great thing about web wallets is that you can easily access them. All you need is an internet connection.

  • MyEtherWallet
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts.
In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section.
https://preview.redd.it/j7wzg5ki0mh31.png?width=1088&format=png&auto=webp&s=41383744e961877ba6acbf128be7fdcb2f4baf77

  • Coinbase
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface.
One of the major drawbacks of this wallet is that users don’t control their private keys.

  • MetaMask
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.

Desktop Wallets

There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.

  • Exodus
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature.
The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.

  • Atomic Wallet
Atomic Wallet has a very convenient interface which is suitable even for the beginners. It supports Ethereum and all the ERC20 tokens.The wallet supports atomic swaps. So you can not only have one wallet for Ethereum and all the ERC20 tokens but also exchange them with another user.
Unfortunately, it doesn’t have a hardware wallet yet. So the level of security may not be very high.

https://preview.redd.it/e13whvvl0mh31.png?width=1024&format=png&auto=webp&s=8ee93d65adfcee76b0f8043c6ae1e4c022c16c0b

  • Mist
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain.
Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.

Mobile Wallets

Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.

  • Jaxx Liberty
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use.
However, the security of this wallet raises some questions.

  • Coinomi
Coinomi is an Android app. It is easy to use and supports a wide range of cryptocurrencies. With this wallet, you don’t have to think about backup. Coinomi has a feature that helps you to keep all the information. It is secure enough. Your private keys are nowhere but on your device. Coinomi protects the user’s identity when they sign up.
Unfortunately, so far there is only an app for Android.

https://preview.redd.it/4iyn26do0mh31.png?width=1604&format=png&auto=webp&s=7a9d58bb81911aa336aa93320dbdae5f763d4a3e

Paper Wallets

Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.

  • ethaddress
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.

Bottos 2020 Research and Development Scheme

Bottos 2020 Research and Development Scheme

https://preview.redd.it/umh8ivbsua841.png?width=554&format=png&auto=webp&s=5c16d9d9e61503e4c9d44212eecd176eda11550a
As 2020 is now here, Bottos has solemnly released its “2020 Research and development scheme”. On one hand, we adhere to the principle of transparency so that the whole community can comprehend our next step as a whole, but more importantly, it also helps our whole team to think deeply about the future and reach consensus. It is strongly believed that following these consistent follow-ups will help us to in order to achieve the best results.
Based on the efficient development of Bottos, the team’s technical achievements in consensus algorithms and smart contracts are used to deeply implement and optimize the existing technical architecture. At the same time using the community’s technical capabilities, horizontal development, expanding new functional modules and technical directions it stays closely integrated with the whole community.
In the future, we will keep on striving to achieve in-depth thinking, comprehensive planning, and flexible adjustment.


Overview of Technical Routes

https://preview.redd.it/rk9tpg2uua841.png?width=554&format=png&auto=webp&s=77e607b81f31c0d20feaa90eca81f09a23addca4
User feedback within the community is the driving force behind Bottos progress. In the development route of the community and industry we have formulated a roadmap for technical development, pointing out the right path for the team towards the right direction among the massive routes of modern technology.
As part of our 2020 research and development objective we have the following arrangements:
1. Intensifying enormous number of smart contracts and related infrastructures
After many years of development, smart contracts have gradually become the core and standard function in blockchain projects. The strength of smart contracts, ease of use, and stability represent the key capabilities of a blockchain project. As a good start, Bottos has already made great progress in the field of smart contracts. In smart contracts we still need to increase development efforts, making the ease of use and stability of smart contracts the top priority of our future development.
Reducing the barriers for developers and ordinary users to use, shortening the contract development cycle and saving users time is another important task for the team to accomplish. To this end, we have planned an efficient and easy-to-use one-stop contract development, debugging, and deployment tool that will provide multiple access methods and interfaces to the test network to support rapid deployment and rapid debugging.
2. Establishing an excellent client and user portal
The main goal here is to add an entrance point to the creation and deployment of smart contracts in the wallet client. To this end, the wallet needs to be transformed, a local compiler for smart contracts must be added, and an easy-to-use UI interface can be provided for the purpose of creating, deploying, and managing contracts to meet the needs of users with a single mouse click only.
3. Expanding distributed storage
Distributed storage is another focus of our development in the upcoming year. Only by using a distributed architecture can completely solve the issue of performance and scalability of stand-alone storage. Distributed storage suitable for blockchain needs to provide no less than single machine performance, extremely high availability, no single point of failure, easy expansion, and strong consistent transactions. These are the main key points and difficulties of Bottos in field of distributed storage in the upcoming days.
4. Reinforcing multi party secured computing
Privacy in computing is also a very important branch to deal with. In this research direction, Bottos has invested a lot of time and produced many research results on multi-party secured computing, such as technical articles and test cases. In the future, we will continue to give efforts in the direction of multi-party secured computing and apply mature technology achievements into the functions of the chain.

2020 Bottos — Product Development

Support for smart contract deployment in wallets
The built-in smart contract compiler inside the wallet supports compilation of the smart contracts in all languages provided by Bottos and integrates with the functions in the wallet. It also supports one-click deployment of the compiled contract source code in the wallet.
When compiling a contract, one can choose whether to pre-execute the contract code. If pre-execution is selected, it will connect to the remote contract pre-execution service and return the execution result to the wallet.
When deploying a contract, one can choose to deploy to the test network or main network and the corresponding account and private key of the test network or main network should be provided.

2020 Bottos-Technical Research

1. Intelligent smart contract development platform (BISDP)
The smart contract development platform BISDP is mainly composed of user-oriented interfaces, as well as back-end compilation and deployment tools, debugging tools, and pre-execution frameworks.
The user-oriented interface provides access methods based on WEB, PC, and mobile apps, allowing developers to quickly and easily compile and deploy contracts and provide contract template management functions. It can also manage the contract remotely by viewing the contract execution status, the consumed resources and other information.
In the compilation and deployment tool a set of smart contract source code editing, running, debugging, and deployment solutions as well as smart contract templates for common tasks are provided, which greatly reduces the threshold for developers to learn and use smart contracts. At the same time, developers and ordinary users are provided with a smart contract pre-execution framework, which can check the logical defects and security risks in smart contracts before actual deployment and promptly remind users a series of problems even before the smart contracts are actually run.
In the debugging tool, there are built-in local debugging and remote debugging tools. Multiple breakpoints can be set in the debugging tool. When the code reaches the breakpoint, one can view the variables and their contents in the current execution stack. One can also make conditional breakpoints based on the value of the variable. The code will not execute until the value reaches a preset value in memory.
In the pre-execution framework, developers can choose to pre-execute contract code in a virtual environment or a test net, checking out problems in some code that cannot be detected during compilation time and perform deeper code inspection. The pre-execution framework can also prompt the user in advance about the time and space resources required for execution.
2. Supporting Python and PHP in BVM virtual machine for writing smart contracts
We have added smart contract writing tools based on Python and PHP languages. These languages can be compiled into the corresponding BVM instruction set for implementation. These two reasons are used as the programming language for smart contracts.
For the Python language, the basic language elements supported by the first phase are:
- Logic control: If, Else, Eli, While, Break, method calls, for x in y
- Arithmetic and relational operators: ADD, SUB, MUL, DIV, ABS, LSHIFT, RSHIFT, AND, OR, XOR, MODULE, INVERT, GT, GTE, LT, LTE, EQ, NOTEQ
-
Data structure:
- Supports creation, addition, deletion, replacement, and calculation of length of list data structure
- Supports creation, append, delete, replace, and calculation of length of dict data structure
Function: Supports function definition and function calls
For the PHP language, the basic language elements supported by the first phase are :
- Logic control: If, Else, Eli, While, Break, method calls
- Arithmetic and relational operators: ADD, SUB, MUL, DIV, ABS, LSHIFT, RSHIFT, AND, OR, XOR, MODULE, INVERT, GT, GTE, LT, LTE, EQ, NOTEQ
Data structure:
- Support for creating, appending, deleting, replacing, and calculating length of associative arrays
Function: Supports the definition and calling of functions
For these two above mentioned languages, the syntax highlighting and code hinting functions are also provided in BISDP, which is very convenient for developers to debug any errors.
3. Continuous exploration of distributed storage solutions
Distributed storage in blockchain technology actually refers to a distributed database. Compared with the traditional DMBS, in addition to the ACID characteristics of the traditional DBMS, the distributed database also provides the high availability and horizontal expansion of the distributed system. The CAP principle of distributed system reveals that for a common distributed system there is an impossible triangle, only two of them can be selected among its three directions, consistency, availability, and partition fault tolerance. Distributed databases in China must require strong consistency. This is due to the characteristics of the blockchain system itself, because it needs to provide reliable distributed transaction capabilities. For these technical issues, before ensuring that the distributed storage solution reaches 100% availability, we will continue to invest more time and technical strength, do more functional and performance testing, and conduct targeted tests for distributed storage systems.
4. Boosting secured multi-party computing research and development
Secured multi-party Computing (MPC) is a cryptographic mechanism that enables multiple entities to share data while protecting the confidentiality of the data without exposing the secret encryption key. Its performance indicators, such as security and reliability are important for the realization of the blockchain. The transparent sharing of the data privacy on the distributed ledger and the privacy protection of the client wallet’s private key are truly essential.
At present, the research and development status of the platform provided by Bottos in terms of privacy-enhanced secured multi-party computing is based on the BIP32 / 44 standard in Bitcoin wallets to implement distributed management of client wallet keys and privacy protection.
Considering the higher level of data security and the distributed blockchain account as the public data of each node, further research and development are being planned on:
(1) Based on RSA, Pailliar, ECDSA and other public key cryptosystems with homomorphic attributes, as well as the GC protocol, OT protocol, and ZKP protocol to generate and verify transaction signatures between two parties;
(2) Introduce the international mainstream public key system with higher security and performance, national secret public key encryption system, and fewer or non-interactive ZKP protocols to achieve secured multi-party computing with more than two parties, allowing more nodes to participate Privacy protection of ledger data.

Summary

After years of exploration, we are now full of confidence in our current research and development direction. We are totally determined to move forward by continuous hard work. In the end, all members of Bottos also want to thank all the friends in the community for their continuous support and outstanding contributions. Your certainty is our greatest comfort and strongest motivation.
