Hello,
Please, does someone know which BTC "from address" should be used in point number 17? I sent BTC from another exchange to Bitgrail. Standardly, the exchange shows you deposit / withdraw address, but this address isn't used as input in transaction for blockchain explorer. This deposit / withdraw address is used only for transactions within the exchange. Once you are going to do withdraw, the exchange sent your transfer from your deposit / withdraw address to the hot exchange wallet address which is used as input in a blockchain transaction.
So the question is which of these two addresses should be used as "from address" in point number 17? "deposit / withdraw address" or "hot exchange wallet address" ?

The better sense gives me using "hot exchange wallet address" which is recorded in the transaction and traceable in the blockchain explorer. But the problem happens in inputs containing more addresses for each transaction. Should I write all addresses? Look at this article and scroll down "Change addresses": https://www.thebalance.com/how-does-a-bitcoin-transaction-work-391213 to better understand what I mean.

Hello everyone,
I would not like to bother members who are tired of reading about Bitgrail. But many supporters have became the victims of Bitgrail theft. I guess that here is still many victims, who aren't in BGInsolvency group. Maybe some of you have already sent claim to Truestee. I am confused about the point number 17, if is here someone who could help?

How exactly does a bitcoin atm work ? We all know btc transaction times can vary greatly, someone walk me through what it's like to get cash for btc from an atm

I posted this question as a comment in that thread about the btc atm at the music festival but didn't get any succinct answers. With transaction times varying so wildly, how does it work? Of course I can imagine several scenarios, but how do existing machines actually accomplish the task of verifying your btc transaction and then giving you cash? How long does it take on average? Do you have to enter any information, or does it just give you a one time use btc address to send to and that's it?
Someone lucky enough to have access to one of these and use them regularly, fill me in on the actual user experience.

How much to pay as a fee for a transaction to move Bitcoin? Does this reference site work?

Trying to get the greenaddress wallet to work. Seeing an error saying the fee is to low for a transfer. It was set to 'normal' transaction in the config.
This site: np//bitcoinfees.earn.com/#fees would suggest that the fee per kb should be about btc 0.0000033/kb for a quick throughput. So... why does GreenAddress say it is too low?
What are the average BTC/kBvalues for GreenAddress normal transactions?

Coinbase's CEO Brian Armstrong is a hero for not making Bitcoin about race

It started back in June, amid the nationwide protests over the death of George Floyd, when Brian Armstrong, the company’s extremely introverted cofounder and CEO, was asked a question at an employee town hall about why Coinbase had not shown public support for the Black Lives Matter movement. Armstrong declined to give a clear answer, according to crypto news site The Block, and his avoidance resulted in a virtual walkout by “hundreds” of Coinbase’s 1,100 employees on June 3.
In response, Armstrong has made Coinbase's mission clear: it's not political. He has given severance packages to employees who disagree. And this, I believe, is how any business ought to be run. If you want to make *everything* political, you should join a political party. Corporations and businesses are not political. It's no different from the separation of Church and State. You ought to separate business from political, especially the feverish social-justice-warrior kind.
I think Armstrong deserves some goddamn respect for having a spine.
FYI- Bitcoin isn't about race. It isn't a "white supremacist" technology. Most Bitcoin miners are living in China. It's a global asset. Inventor Satoshi Nakamoto specifically designed Bitcoin to be able to process transactions on slow third-world internet connections (and it does work in Africa, and India, too). Bitcoin was always, first and foremost, a *human* technology, for everyone to use to avoid financial censorship.
Insurgent employees trying to blackmail their own CEO into making everything about race IS NOT OK.

What we can learn from Litecoin falling out of Top10

So as LTC is dropping out of Top10 coins on cmc for the first time (currently sitting at 12) I think it is time to get some insights out of its demise.
Many people in crypto community (especially here in btc) know that LTC is, while not being an outright shitcoin, basically a useless coin. The advantages it had over BTC were really small for most of its lifetime (except for BTC high fee times), and compared to most other alts it was inferior. It had no roadmap other than being a testing ground for BTC and backporting their changes. But what it had, was a clever marketing or "story to tell". Litecoin is silver to BTC's gold. With this simple marketing trick it managed to closely align it to Cryptos biggest Community (BTC) and also paved the way for the greatest dogma in crypto that developed over the years: that Bitcoin is not meant to be spend BTC rather hoarded like gold and if you need to make actual crypto payment you do it with Litecoin.
This marketing ensured that LTC could stay in Top10 for almost a decade, whereas other coins out of the 2011-2013 copycat altcoin era, even some that provided actual advantage (think of Peercoin for example) have long been forgotton.
So what can we learn from this? In crypto community there is a lot of joking about the market being irrational, shitcoins like IOTA which do not even work having the same price development as legit projects, useless projects pumping like mad because they spend all their ICO money on marketing, sentiments like "the market can stay longer irrational than you can solvent" and so and so on. In the case of LTC it is now possible to quantify how long the market can stay irrational in extreme cases: Almost a decade. Measured in crypto time frames almost an eternity, but not a lifespan.
Also important to note is that Litecoin compared to BCH has (even before their current artificial increase) better onchain stats regarding transaction count, active adresses etc. Nevertheless the gap between the coins continues to widen. The market DOES price in tech, future outlook, roadmap and things alike.
So in conclusion: 1. Marketing is extremely important and can outweigh actual tech and roadmap in the short and mid-term (up to 8 years in extreme cases), but not in the long term. 2. Community sentiment can have tremendous impact, just because LTC aligned closely with BTC community they managed to survive much longer than similiar projects from the era. 3. Over time the market does take into account future perspective and outlook.
BCH should take steps accordingly, continue to invest in solid and novel tech, but also increase its reputation in the wider crypto community (pro tip: not constantly shitting on other projects help). In a few years we can earn the fruit of it.
Another thing that came to my mind is that crypto market actually works the direct opposite of current stock market. In crypto, everything changes super fast but the actual market elements to work (valuing fundamental value, expectation trading) takes ages. In stock market (if you look at Tesla for example) things go way slower but basic market functions are comparably quicker (as seen in Tesla having better stock than other car manufacturers, despite being arguably profitable and delivering much less cars, but what matters is actual tech and future expectations).
What do you think of the analysis?

Realistically - What happens when the Nano Developer Fund runs out?

I'm a very big fan of this project and think Nano is truly the best decentralized coin for payments. Nano is everything Bitcoin should have been - free, instant P2P payments. Every time I use it I am amazed by how fast the transactions are and how they are fully confirmed after ~3 seconds.
This project already has "the tech", but the X-Factoelephant in the room is the dev fund. For whatever reason, the devs of this project seem to require a massive amount of Nano ($) in order to keep the project going. In addition, even with all the funds that are being cashed out monthly (~$40,000-$50,000/month), this project engages in very little marketing (and if the team does engage in marketing, it's not very effective, as many community members have noted). From an investment perspective, I think many people are concerned about the longevity of this project.
The main questions here are:
I love Nano and want to see it succeed. I just hope funding isn't the downfall of this project.

Comparison between Avalanche, Cosmos and Polkadot

Comparison between Avalanche, Cosmos and Polkadot
Reposting after was mistakenly removed by mods (since resolved - Thanks)
A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important.
For better formatting see https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b
https://preview.redd.it/e8s7dj3ivpq51.png?width=428&format=png&auto=webp&s=5d0463462702637118c7527ebf96e91f4a80b290

Overview

Cosmos

Cosmos is a heterogeneous network of many independent parallel blockchains, each powered by classical BFT consensus algorithms like Tendermint. Developers can easily build custom application specific blockchains, called Zones, through the Cosmos SDK framework. These Zones connect to Hubs, which are specifically designed to connect zones together.
The vision of Cosmos is to have thousands of Zones and Hubs that are Interoperable through the Inter-Blockchain Communication Protocol (IBC). Cosmos can also connect to other systems through peg zones, which are specifically designed zones that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Cosmos does not use Sharding with each Zone and Hub being sovereign with their own validator set.
For a more in-depth look at Cosmos and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Cosmos on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Polkadot

Polkadot is a heterogeneous blockchain protocol that connects multiple specialised blockchains into one unified network. It achieves scalability through a sharding infrastructure with multiple blockchains running in parallel, called parachains, that connect to a central chain called the Relay Chain. Developers can easily build custom application specific parachains through the Substrate development framework.
The relay chain validates the state transition of connected parachains, providing shared state across the entire ecosystem. If the Relay Chain must revert for any reason, then all of the parachains would also revert. This is to ensure that the validity of the entire system can persist, and no individual part is corruptible. The shared state makes it so that the trust assumptions when using parachains are only those of the Relay Chain validator set, and no other. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. The hope is to have 100 parachains connect to the relay chain.
For a more in-depth look at Polkadot and provide more reference to points made in this article, please see my three part series — Part One, Part Two, Part Three
(There's a youtube video with a quick video overview of Polkadot on the medium article - https://medium.com/ava-hub/comparison-between-avalanche-cosmos-and-polkadot-a2a98f46c03b)

Avalanche

Avalanche is a platform of platforms, ultimately consisting of thousands of subnets to form a heterogeneous interoperable network of many blockchains, that takes advantage of the revolutionary Avalanche Consensus protocols to provide a secure, globally distributed, interoperable and trustless framework offering unprecedented decentralisation whilst being able to comply with regulatory requirements.
Avalanche allows anyone to create their own tailor-made application specific blockchains, supporting multiple custom virtual machines such as EVM and WASM and written in popular languages like Go (with others coming in the future) rather than lightly used, poorly-understood languages like Solidity. This virtual machine can then be deployed on a custom blockchain network, called a subnet, which consist of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance.
Avalanche was built with serving financial markets in mind. It has native support for easily creating and trading digital smart assets with complex custom rule sets that define how the asset is handled and traded to ensure regulatory compliance can be met. Interoperability is enabled between blockchains within a subnet as well as between subnets. Like Cosmos and Polkadot, Avalanche is also able to connect to other systems through bridges, through custom virtual machines made to interact with another ecosystem such as Ethereum and Bitcoin.

Comparison between Cosmos, Polkadot and Avalanche

A frequent question I see being asked is how Cosmos, Polkadot and Avalanche compare? Whilst there are similarities there are also a lot of differences. This article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions. I want to stress that it’s not a case of one platform being the killer of all other platforms, far from it. There won’t be one platform to rule them all, and too often the tribalism has plagued this space. Blockchains are going to completely revolutionise most industries and have a profound effect on the world we know today. It’s still very early in this space with most adoption limited to speculation and trading mainly due to the limitations of Blockchain and current iteration of Ethereum, which all three of these platforms hope to address. For those who just want a quick summary see the image at the bottom of the article. With that said let’s have a look

Scalability

Cosmos

Each Zone and Hub in Cosmos is capable of up to around 1000 transactions per second with bandwidth being the bottleneck in consensus. Cosmos aims to have thousands of Zones and Hubs all connected through IBC. There is no limit on the number of Zones / Hubs that can be created

Polkadot

Parachains in Polkadot are also capable of up to around 1500 transactions per second. A portion of the parachain slots on the Relay Chain will be designated as part of the parathread pool, the performance of a parachain is split between many parathreads offering lower performance and compete amongst themselves in a per-block auction to have their transactions included in the next relay chain block. The number of parachains is limited by the number of validators on the relay chain, they hope to be able to achieve 100 parachains.

Avalanche

Avalanche is capable of around 4500 transactions per second per subnet, this is based on modest hardware requirements to ensure maximum decentralisation of just 2 CPU cores and 4 GB of Memory and with a validator size of over 2,000 nodes. Performance is CPU-bound and if higher performance is required then more specialised subnets can be created with higher minimum requirements to be able to achieve 10,000 tps+ in a subnet. Avalanche aims to have thousands of subnets (each with multiple virtual machines / blockchains) all interoperable with each other. There is no limit on the number of Subnets that can be created.

Results

All three platforms offer vastly superior performance to the likes of Bitcoin and Ethereum 1.0. Avalanche with its higher transactions per second, no limit on the number of subnets / blockchains that can be created and the consensus can scale to potentially millions of validators all participating in consensus scores ✅✅✅. Polkadot claims to offer more tps than cosmos, but is limited to the number of parachains (around 100) whereas with Cosmos there is no limit on the number of hubs / zones that can be created. Cosmos is limited to a fairly small validator size of around 200 before performance degrades whereas Polkadot hopes to be able to reach 1000 validators in the relay chain (albeit only a small number of validators are assigned to each parachain). Thus Cosmos and Polkadot scores ✅✅
https://preview.redd.it/2o0brllyvpq51.png?width=1000&format=png&auto=webp&s=8f62bb696ecaafcf6184da005d5fe0129d504518

Decentralisation

Cosmos

Tendermint consensus is limited to around 200 validators before performance starts to degrade. Whilst there is the Cosmos Hub it is one of many hubs in the network and there is no central hub or limit on the number of zones / hubs that can be created.

Polkadot

Polkadot has 1000 validators in the relay chain and these are split up into a small number that validate each parachain (minimum of 14). The relay chain is a central point of failure as all parachains connect to it and the number of parachains is limited depending on the number of validators (they hope to achieve 100 parachains). Due to the limited number of parachain slots available, significant sums of DOT will need to be purchased to win an auction to lease the slot for up to 24 months at a time. Thus likely to lead to only those with enough funds to secure a parachain slot. Parathreads are however an alternative for those that require less and more varied performance for those that can’t secure a parachain slot.

Avalanche

Avalanche consensus scan scale to tens of thousands of validators, even potentially millions of validators all participating in consensus through repeated sub-sampling. The more validators, the faster the network becomes as the load is split between them. There are modest hardware requirements so anyone can run a node and there is no limit on the number of subnets / virtual machines that can be created.

Results

Avalanche offers unparalleled decentralisation using its revolutionary consensus protocols that can scale to millions of validators all participating in consensus at the same time. There is no limit to the number of subnets and virtual machines that can be created, and they can be created by anyone for a small fee, it scores ✅✅✅. Cosmos is limited to 200 validators but no limit on the number of zones / hubs that can be created, which anyone can create and scores ✅✅. Polkadot hopes to accommodate 1000 validators in the relay chain (albeit these are split amongst each of the parachains). The number of parachains is limited and maybe cost prohibitive for many and the relay chain is a ultimately a single point of failure. Whilst definitely not saying it’s centralised and it is more decentralised than many others, just in comparison between the three, it scores ✅
https://preview.redd.it/ckfamee0wpq51.png?width=1000&format=png&auto=webp&s=c4355f145d821fabf7785e238dbc96a5f5ce2846

Latency

Cosmos

Tendermint consensus used in Cosmos reaches finality within 6 seconds. Cosmos consists of many Zones and Hubs that connect to each other. Communication between 2 zones could pass through many hubs along the way, thus also can contribute to latency times depending on the path taken as explained in part two of the articles on Cosmos. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Polkadot

Polkadot provides a Hybrid consensus protocol consisting of Block producing protocol, BABE, and then a finality gadget called GRANDPA that works to agree on a chain, out of many possible forks, by following some simpler fork choice rule. Rather than voting on every block, instead it reaches agreements on chains. As soon as more than 2/3 of validators attest to a chain containing a certain block, all blocks leading up to that one are finalized at once.
If an invalid block is detected after it has been finalised then the relay chain would need to be reverted along with every parachain. This is particularly important when connecting to external blockchains as those don’t share the state of the relay chain and thus can’t be rolled back. The longer the time period, the more secure the network is, as there is more time for additional checks to be performed and reported but at the expense of finality. Finality is reached within 60 seconds between parachains but for external ecosystems like Ethereum their state obviously can’t be rolled back like a parachain and so finality will need to be much longer (60 minutes was suggested in the whitepaper) and discussed in more detail in part three

Avalanche

Avalanche consensus achieves finality within 3 seconds, with most happening sub 1 second, immutable and completely irreversible. Any subnet can connect directly to another without having to go through multiple hops and any VM can talk to another VM within the same subnet as well as external subnets. It doesn’t need to wait for an extended period of time with risk of rollbacks.

Results

With regards to performance far too much emphasis is just put on tps as a metric, the other equally important metric, if not more important with regards to finance is latency. Throughput measures the amount of data at any given time that it can handle whereas latency is the amount of time it takes to perform an action. It’s pointless saying you can process more transactions per second than VISA when it takes 60 seconds for a transaction to complete. Low latency also greatly increases general usability and customer satisfaction, nowadays everyone expects card payments, online payments to happen instantly. Avalanche achieves the best results scoring ✅✅✅, Cosmos with comes in second with 6 second finality ✅✅ and Polkadot with 60 second finality (which may be 60 minutes for external blockchains) scores ✅
https://preview.redd.it/kzup5x42wpq51.png?width=1000&format=png&auto=webp&s=320eb4c25dc4fc0f443a7a2f7ff09567871648cd

Shared Security

Cosmos

Every Zone and Hub in Cosmos has their own validator set and different trust assumptions. Cosmos are researching a shared security model where a Hub can validate the state of connected zones for a fee but not released yet. Once available this will make shared security optional rather than mandatory.

Polkadot

Shared Security is mandatory with Polkadot which uses a Shared State infrastructure between the Relay Chain and all of the connected parachains. If the Relay Chain must revert for any reason, then all of the parachains would also revert. Every parachain makes the same trust assumptions, and as such the relay chain validates state transition and enables seamless interoperability between them. In return for this benefit, they have to purchase DOT and win an auction for one of the available parachain slots.
However, parachains can’t just rely on the relay chain for their security, they will also need to implement censorship resistance measures and utilise proof of work / proof of stake for each parachain as well as discussed in part three, thus parachains can’t just rely on the security of the relay chain, they need to ensure sybil resistance mechanisms using POW and POS are implemented on the parachain as well.

Avalanche

A subnet in Avalanche consists of a dynamic set of validators working together to achieve consensus on the state of a set of many blockchains where complex rulesets can be configured to meet regulatory compliance. So unlike in Cosmos where each zone / hub has their own validators, A subnet can validate a single or many virtual machines / blockchains with a single validator set. Shared security is optional

Results

Shared security is mandatory in polkadot and a key design decision in its infrastructure. The relay chain validates the state transition of all connected parachains and thus scores ✅✅✅. Subnets in Avalanche can validate state of either a single or many virtual machines. Each subnet can have their own token and shares a validator set, where complex rulesets can be configured to meet regulatory compliance. It scores ✅ ✅. Every Zone and Hub in cosmos has their own validator set / token but research is underway to have the hub validate the state transition of connected zones, but as this is still early in the research phase scores ✅ for now.

Current Adoption

Cosmos

The Cosmos project started in 2016 with an ICO held in April 2017. There are currently around 50 projects building on the Cosmos SDK with a full list can be seen here and filtering for Cosmos SDK . Not all of the projects will necessarily connect using native cosmos sdk and IBC and some have forked parts of the Cosmos SDK and utilise the tendermint consensus such as Binance Chain but have said they will connect in the future.

Polkadot

The Polkadot project started in 2016 with an ICO held in October 2017. There are currently around 70 projects building on Substrate and a full list can be seen here and filtering for Substrate Based. Like with Cosmos not all projects built using substrate will necessarily connect to Polkadot and parachains or parathreads aren’t currently implemented in either the Live or Test network (Kusama) as of the time of this writing.

Avalanche

Avalanche in comparison started much later with Ava Labs being founded in 2018. Avalanche held it’s ICO in July 2020. Due to lot shorter time it has been in development, the number of projects confirmed are smaller with around 14 projects currently building on Avalanche. Due to the customisability of the platform though, many virtual machines can be used within a subnet making the process incredibly easy to port projects over. As an example, it will launch with the Ethereum Virtual Machine which enables byte for byte compatibility and all the tooling like Metamask, Truffle etc. will work, so projects can easily move over to benefit from the performance, decentralisation and low gas fees offered. In the future Cosmos and Substrate virtual machines could be implemented on Avalanche.

Results

Whilst it’s still early for all 3 projects (and the entire blockchain space as a whole), there is currently more projects confirmed to be building on Cosmos and Polkadot, mostly due to their longer time in development. Whilst Cosmos has fewer projects, zones are implemented compared to Polkadot which doesn’t currently have parachains. IBC to connect zones and hubs together is due to launch Q2 2021, thus both score ✅✅✅. Avalanche has been in development for a lot shorter time period, but is launching with an impressive feature set right from the start with ability to create subnets, VMs, assets, NFTs, permissioned and permissionless blockchains, cross chain atomic swaps within a subnet, smart contracts, bridge to Ethereum etc. Applications can easily port over from other platforms and use all the existing tooling such as Metamask / Truffle etc but benefit from the performance, decentralisation and low gas fees offered. Currently though just based on the number of projects in comparison it scores ✅.

Cosmos enables permissioned and permissionless zones which can connect to each other with the ability to have full control over who validates the blockchain. For permissionless zones each zone / hub can have their own token and they are in control who validates.

Polkadot

With polkadot the state transition is performed by a small randomly selected assigned group of validators from the relay chain plus with the possibility that state is rolled back if an invalid transaction of any of the other parachains is found. This may pose a problem for enterprises that need complete control over who performs validation for regulatory reasons. In addition due to the limited number of parachain slots available Enterprises would have to acquire and lock up large amounts of a highly volatile asset (DOT) and have the possibility that they are outbid in future auctions and find they no longer can have their parachain validated and parathreads don’t provide the guaranteed performance requirements for the application to function.

Avalanche

Avalanche enables permissioned and permissionless subnets and complex rulesets can be configured to meet regulatory compliance. For example a subnet can be created where its mandatory that all validators are from a certain legal jurisdiction, or they hold a specific license and regulated by the SEC etc. Subnets are also able to scale to tens of thousands of validators, and even potentially millions of nodes, all participating in consensus so every enterprise can run their own node rather than only a small amount. Enterprises don’t have to hold large amounts of a highly volatile asset, but instead pay a fee in AVAX for the creation of the subnets and blockchains which is burnt.

Results

Avalanche provides the customisability to run private permissioned blockchains as well as permissionless where the enterprise is in control over who validates the blockchain, with the ability to use complex rulesets to meet regulatory compliance, thus scores ✅✅✅. Cosmos is also able to run permissioned and permissionless zones / hubs so enterprises have full control over who validates a blockchain and scores ✅✅. Polkadot requires locking up large amounts of a highly volatile asset with the possibility of being outbid by competitors and being unable to run the application if the guaranteed performance is required and having to migrate away. The relay chain validates the state transition and can roll back the parachain should an invalid block be detected on another parachain, thus scores ✅.

Interoperability

Cosmos

Cosmos will connect Hubs and Zones together through its IBC protocol (due to release in Q1 2020). Connecting to blockchains outside of the Cosmos ecosystem would either require the connected blockchain to fork their code to implement IBC or more likely a custom “Peg Zone” will be created specific to work with a particular blockchain it’s trying to bridge to such as Ethereum etc. Each Zone and Hub has different trust levels and connectivity between 2 zones can have different trust depending on which path it takes (this is discussed more in this article). Finality time is low at 6 seconds, but depending on the number of hops, this can increase significantly.

Polkadot

Polkadot’s shared state means each parachain that connects shares the same trust assumptions, of the relay chain validators and that if one blockchain needs to be reverted, all of them will need to be reverted. Interoperability is enabled between parachains through Cross-Chain Message Passing (XCMP) protocol and is also possible to connect to other systems through bridges, which are specifically designed parachains or parathreads that each are custom made to interact with another ecosystem such as Ethereum and Bitcoin. Finality time between parachains is around 60 seconds, but longer will be needed (initial figures of 60 minutes in the whitepaper) for connecting to external blockchains. Thus limiting the appeal of connecting two external ecosystems together through Polkadot. Polkadot is also limited in the number of Parachain slots available, thus limiting the amount of blockchains that can be bridged. Parathreads could be used for lower performance bridges, but the speed of future blockchains is only going to increase.

Avalanche

A subnet can validate multiple virtual machines / blockchains and all blockchains within a subnet share the same trust assumptions / validator set, enabling cross chain interoperability. Interoperability is also possible between any other subnet, with the hope Avalanche will consist of thousands of subnets. Each subnet may have a different trust level, but as the primary network consists of all validators then this can be used as a source of trust if required. As Avalanche supports many virtual machines, bridges to other ecosystems are created by running the connected virtual machine. There will be an Ethereum bridge using the EVM shortly after mainnet. Finality time is much faster at sub 3 seconds (with most happening under 1 second) with no chance of rolling back so more appealing when connecting to external blockchains.

Results

All 3 systems are able to perform interoperability within their ecosystem and transfer assets as well as data, as well as use bridges to connect to external blockchains. Cosmos has different trust levels between its zones and hubs and can create issues depending on which path it takes and additional latency added. Polkadot provides the same trust assumptions for all connected parachains but has long finality and limited number of parachain slots available. Avalanche provides the same trust assumptions for all blockchains within a subnet, and different trust levels between subnets. However due to the primary network consisting of all validators it can be used for trust. Avalanche also has a much faster finality time with no limitation on the number of blockchains / subnets / bridges that can be created. Overall all three blockchains excel with interoperability within their ecosystem and each score ✅✅.

Tokenomics

Cosmos

The ATOM token is the native token for the Cosmos Hub. It is commonly mistaken by people that think it’s the token used throughout the cosmos ecosystem, whereas it’s just used for one of many hubs in Cosmos, each with their own token. Currently ATOM has little utility as IBC isn’t released and has no connections to other zones / hubs. Once IBC is released zones may prefer to connect to a different hub instead and so ATOM is not used. ATOM isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for ATOM as of the time of this writing is $1 Billion with 203 million circulating supply. Rewards can be earnt through staking to offset the dilution caused by inflation. Delegators can also get slashed and lose a portion of their ATOM should the validator misbehave.

Polkadot

Polkadot’s native token is DOT and it’s used to secure the Relay Chain. Each parachain needs to acquire sufficient DOT to win an auction on an available parachain lease period of up to 24 months at a time. Parathreads have a fixed fee for registration that would realistically be much lower than the cost of acquiring a parachain slot and compete with other parathreads in a per-block auction to have their transactions included in the next relay chain block. DOT isn’t a fixed capped supply token and supply will continuously increase with a yearly inflation of around 10% depending on the % staked. The current market cap for DOT as of the time of this writing is $4.4 Billion with 852 million circulating supply. Delegators can also get slashed and lose their DOT (potentially 100% of their DOT for serious attacks) should the validator misbehave.

Avalanche

AVAX is the native token for the primary network in Avalanche. Every validator of any subnet also has to validate the primary network and stake a minimum of 2000 AVAX. There is no limit to the number of validators like other consensus methods then this can cater for tens of thousands even potentially millions of validators. As every validator validates the primary network, this can be a source of trust for interoperability between subnets as well as connecting to other ecosystems, thus increasing amount of transaction fees of AVAX. There is no slashing in Avalanche, so there is no risk to lose your AVAX when selecting a validator, instead rewards earnt for staking can be slashed should the validator misbehave. Because Avalanche doesn’t have direct slashing, it is technically possible for someone to both stake AND deliver tokens for something like a flash loan, under the invariant that all tokens that are staked are returned, thus being able to make profit with staked tokens outside of staking itself.
There will also be a separate subnet for Athereum which is a ‘spoon,’ or friendly fork, of Ethereum, which benefits from the Avalanche consensus protocol and applications in the Ethereum ecosystem. It’s native token ATH will be airdropped to ETH holders as well as potentially AVAX holders as well. This can be done for other blockchains as well.
Transaction fees on the primary network for all 3 of the blockchains as well as subscription fees for creating a subnet and blockchain are paid in AVAX and are burnt, creating deflationary pressure. AVAX is a fixed capped supply of 720 million tokens, creating scarcity rather than an unlimited supply which continuously increase of tokens at a compounded rate each year like others. Initially there will be 360 tokens minted at Mainnet with vesting periods between 1 and 10 years, with tokens gradually unlocking each quarter. The Circulating supply is 24.5 million AVAX with tokens gradually released each quater. The current market cap of AVAX is around $100 million.

Results

Avalanche’s AVAX with its fixed capped supply, deflationary pressure, very strong utility, potential to receive air drops and low market cap, means it scores ✅✅✅. Polkadot’s DOT also has very strong utility with the need for auctions to acquire parachain slots, but has no deflationary mechanisms, no fixed capped supply and already valued at $3.8 billion, therefore scores ✅✅. Cosmos’s ATOM token is only for the Cosmos Hub, of which there will be many hubs in the ecosystem and has very little utility currently. (this may improve once IBC is released and if Cosmos hub actually becomes the hub that people want to connect to and not something like Binance instead. There is no fixed capped supply and currently valued at $1.1 Billion, so scores ✅.

All three are excellent projects and have similarities as well as many differences. Just to reiterate this article is not intended to be an extensive in-depth list, but rather an overview based on some of the criteria that I feel are most important. For a more in-depth view I recommend reading the articles for each of the projects linked above and coming to your own conclusions, you may have different criteria which is important to you, and score them differently. There won’t be one platform to rule them all however, with some uses cases better suited to one platform over another, and it’s not a zero-sum game. Blockchain is going to completely revolutionize industries and the Internet itself. The more projects researching and delivering breakthrough technology the better, each learning from each other and pushing each other to reach that goal earlier. The current market is a tiny speck of what’s in store in terms of value and adoption and it’s going to be exciting to watch it unfold.

MW Wyco Wednesday is BACK and Better Than Ever After a Long(er than anticipated) Break! First 20 Orders and Orders Ending in 1, 0 or 7 on 10/7 Get Something Special with Their Order! Restocked GT, B+, AA+, KSSS, Jedi Mind Fuck, Z-Strain, PE6 and More! New this wk Acadian Coast, NorMel, White Teacher

www.millywyco.com Stickers=12mL Syringes
MillyWyco is NOT Willy Myco :) (see below)
Any mention of cultivation or anything unrelated to microscopy will not receive a response and orders will be cancelled. This includes DM's, PM's, e-mails, notes with your transaction, feedback of any kind, and thoughts. Don't even think about it! (I'm a mind reader)
Wowowowow! I am in complete awe over the support and love I received during that much needed break. It was needed maybe a bit more than I even knew, and at so many moments during that break, I could literally feel the positive energy coming at me from all sides of this community. I struggled for a couple weeks before the break, going back and forth on whether or not to take a breather, but all of that anxiety went away hearing from all of you about how crucial it is to take time for self-reflection and balance. Mission 100% accomplished. I cannot thank you all enough for giving me this opportunity to live my absolute dream and passion for getting people into this hobby. Ya'll seriously keep me going and I can only help the feeling is mutual.
I'll be writing in a separate post about the highs (and lows) of the journey this past month for any who care to escape from their own reality a bit and step into such a fulfilling adventure with my experiences. I encourage you all to chime in with your own ups, downs and sideways ventures as well! We're all in this together :)
To ensure quality specimens and packaging, and due to the onslaught of orders on Wednesdays, all orders placed on Wednesday will be shipped on Thursday and Friday of that week (ALL Priority Mail and subscription box orders will ship on Thursday). You will receive an email notification with a tracking link when your order ships. I appreciate your patience so hard!
Also, when I say "Priority Mail", this is referring to USPS Priority Mail vs. the standard "First Class" mail. All of my orders get my absolute highest priority care and attention, regardless of shipping method. USPS Priority Mail costs me $8, while I only pass on $5 of that to your order...it does not benefit me in any way if you choose this option, I just know those orders need to get to you ASAP, so I make sure to get all of these out on Thursday, with as many standard shipping orders as well. Sometimes it is not humanly possible to get every order from Wednesday out on Thursday, and some ship Friday morning. Thank you for your patience and continued support!!
The first 20 orders placed after this post (Order #14432-14451) will receive something special with their order! I am giving away a couple super cool tapestries, a few books that can benefit everyone in this community, a few hand-made fabric mushroom masks, and some resin crafts, as well as unlisted variety syringes! Quantities of the special items are very limited, so requests cannot be guaranteed, but if you would prefer one of the items mentioned above over another, please add a note with your transaction and I will do my best to make it happen!
ALSO...in addition to the first 20 promo, any order number ending in 1, 0 or 7 on 10/7 only will also get a free unlisted variety! If you are in the first 20, and your order number ends in 1, 0, or 7, you get both!
If your order number ends in 07 (#14507, 14607, etc.) the week of 10/7 only, I will be in contact to arrange your special gift. Either you can have a double order (you ordered 5, I'll ask which other 5 you'd like...if you ordered 10, you'll get 20, etc), or you can choose to make that order free, (refunded if already paid) totally up to you!
This week, I have restocked a few favorites, including Golden Teacher, B+, PE6, Alacabenzi, Albino A+, KSSS, Blue Meanie, Z-Strain, Mazatapec, Jedi Mind Fuck, McKennaii, Tasmanian, Rusty Whyte, Fiji, Columbian Rust and a few others!
New additions to the family this week include Acadian Coast (from southern Louisiana), NorMel (Isolate of MelMak with reverted cap shape), and White Teacher (Leucistic Golden Teacher variety, APE/GT hybrid taking the characteristics of GT lacking pigment)
Thank you so much to everyone who has subscribed to a subscription box! Each and every month, these boxes will get better and better :) Newsletters will go out on the first of each month, regardless of when your plan is set to renew. In these newsletters will also be the winner of the random equipment raffle for MASTER PLAN members! This could be a sterilization wand, dehydrator, magnetic stir plate, or other super duper helpful tools in the hobby. Last month, 3 lucky Master Box subscribers received a pressure cooker, UV-C light sterilization wand, and a dehydrator!
PLEASE USE COUPON CODES if ordering on the site for discounts!! Please see below:

All syringes are 12cc/mL and come capped with a sterile tip cap, and also include an 18ga 1.5" sterile needle and alcohol pads. Syringes are made in a lab grade environment and the utmost care and attention is the highest priority to be sure they are sterile. Anything exposed to an open air environment is subject to contamination, but I take every precaution possible to minimize this risk. I cannot "guarantee" they are 100% sterile, but I can guarantee that if you have an issue, I will make it right. I really do love to help, and if something happens, I'd like to know about it so I can fix the issue instead of you getting frustrated or giving up!
To ensure equal quantity of spores in each syringe, and for adequate suspension of the spores in the solution, I use a magnetic stir plate. Very often, this does such a good job of breaking up clumps of spores that it will appear to be sparse. THIS IS NOT AN ISSUE! There are still a TON of spores in each syringe, even if you can't see them individually (though most of my syringes appear to have a very good amount of visible spores...even with my horrible eyesight!). You can compare and contrast to see the blackish/purple tint to ensure every syringe is packed with spores. If a spore clump forms during transportation, simply give it a good flick with your finger and vigorously shake to break it up or free it from clinging to the wall of the syringe before examining.
Syringes ship in individual bags clearly labeled as to specific variety and born on date, bubble wrapped and shipped through USPS tracked shipping (discreet) within 24 hours of payment. I send tracking info soon after payment and give updates along the (super quick) way.
Any messages referring to spores being used for anything other than microscopy use will be ignored. Don't do it.
THANK YOU ALL so much again for your continued support!! I appreciate it more than you know! MUSH LOVE
P.S. In no way am I trying to be an impostor. I AM NOT WILLY MYCO. I chose this u/ a while back as sort of a play on words and tribute to a legend most of us recognize, long before I became a spore vendor. I don't want anyone to think I am trying to pass off as him, though I do admire his dedication to the craft! I appreciate all of the kind words, though, from people saying they learned from "my" videos. I wish I could pass on those notes to Willy himself.
Cheers and MUSH LOVE!

Monero Monetary Policy?

Hello, first time poster here.
From what I can tell, there is significantly less entrenched orthodoxy applied to how monero does things compared to other cryptocurrency. Its the only one with ASIC resistance, has a dynamic block size, is willing to contemplate the concept of linear inflation rather than treating it as an unholy abomination, etc.
In general you guys have done a lot better of a job keeping down transaction fees compared to bitcoin, and as a whole are more inclined to plan for monero as an actual medium of exchange rather than a perpetually deflationary get rich scheme.
With that in mind, I have a few questions:
  1. In the event adoption of this cryptocurrency gets large enough that it ends up putting strain on the current dynamic block size status quo, what's the precise point at which you'll change how things operate in order to prevent a centralization crisis from an excessively large blockchain? What sort of exact security issues/etc prevents things like the lightning network from currently being options for this scenario?
  2. While to a large extent price stability comes from a sufficiently deepened pool of liquidity, as has been seen with recent trends in bitcoin's price, one thing I've got to wonder about is if things such as block rewards and transaction fees can be dynamically adjusted, akin to a more democratic central bank if you will, such that monetary tightening and loosening can be done?
A lack of commitment to permanent deflation would obviously hurt monero's market capitalization, but arguably that's not a particularly important metric compared to transaction volume.
https://finance.yahoo.comyahoo-finance/watchlists/crypto-top-volume-24h
Despite basically being a dubiously backed centralized "cryptocurrency", tether still sees a significant amount of transaction volume purely due to its utility as a unit of currency pegged to the US dollar. Now, while I'm sure precise information on monero's own true transaction volume is under-reported due to strong privacy protections in conjunction with low fees, tether does serve as a reminder for how much demand there is for stability.
Obviously its significantly more difficult to do contractionary monetary policy than inflationary, but would something like say, a decentralized dynamic peg work, where holdings of bitcoin/etc are bought and sold by a digital entity controlled by the miners work in order to stabilize monero? I'm just spitballing thoughts here though and I know there might be potential issues related to chain analysis. If you have any other good reasons why this is a bad idea please feel free to let me know. Thanks!

Hypothetical. I want to send funds to the Kurdish republic of Rojava in Syria to support them during this crisis of theirs, the only way I can do this is through bitcoin (or other crypto).

So what the title says.
Lets say I want to support Rojava because they are one of the few bastions in Syria which is actually secular, liberal and democratic.
I've done so regularly in the past through traditional channels (which has cost a lot of money in fees) and it has worked well.
So this was allowed through traditional means untill Turkey, under americas allowance, invaded their terroritory and forced Rojava to align itself with the syrian government/former government in order to be able to defend themselves against the Turkey army that consider them to be terrorists because they happen to be kurds that have regional autonomy and means to defend themselves. (this is btw after america gave Rojava their guarantee that america would defend the kurds against Turkey if it came to that, in exchange for Rojava dismantling their turkey-facing defensive structures)
From now on, depending on your domiciled country, many westerners can no longer financially support Rojava because of an ocean or reasons. For some its that you're not allowed to financially support states that are in armed conflict with an ally (Turkey is in NATO), for others its that you're not allowed to financially support organisations that cooperate with Assad (nevermind that it was america that put them in the position that they had to), and there is a host of others.
Now how can I support Rojava in any other way than through bitcoin/other crypto?
I've looked it up, it does indeed work and they have bitcoin addresses one can donate too. (as I understand it they even have specified addresses if you want to donate to some specific section, like if you specifically want to support child healthcare)
Now could you please tell me of another comparable or better way to donate to this cause, other than through crypto?
I cant wire it or in any way use banking, its simply not possible due to regs.
I cant send money in the mail because mail delivery over that distance and into syrian territory is spotty at best and if the letter is taken by another group then I've inadvertedly supported what is likely a islamic fundamentalist militia. I also know crypto fees is a big joke in here but the fees to send letters to syria dwarf any crypto transaction fee. (not to mention the fucking headache, I struggle sending packages to the next country over, cant even begin to consider everything that I'll need to do to send something to Syria)
Please let me know how I'm wrong in that this is the best and potentially only way of doing this.
Further let me know how crypto still doesnt have a use case if you agree that I'm right on this.
(Hey mister FBI-guy, if you're reading this I just want it clear that I'm making a hypothetical here. I wouldnt send a cent to godless socialists in the middle east, I'm just a normal american that watches football and boo at the blacks when they kneel, not an ounce of unamerican-ness in my body)

Bitcoin Fullnode Install Guide for Dummies ;-)

Bitcoin Fullnode Install Guide for Dummies ;-)
Feel free to stop at Level 0 or Level 1, which is fine. More advanced configs are offered to those with more tech savvy. This guide, obviously assumes a Windows 10 install, but other OSes work fine, just find a different guide. BTW, the "For Dummies" is a callback to a set of "tech" books in the 90's intended to be as easy as possible. It is in jest and not intended to insult the reader. Finally, if you dislike the formatting, a well formatted copy can be found here
There is a fairly small subset of Bitcoin users that run a full node. I think the idea of running a full node has gotten a bad rap over the years since there is so much talk about running on a Raspberry Pi, or getting zippy SSDs. Although all of this can be fun, it is often not really required at all. Here are some ways to run a full node starting with the very simple. I'll get into more complex configs, but these are all optional.

Tech Skill Level: 0 (the basics)

  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
In many cases, thats it. If your running a new machine with a fairly good internet connection, 8 or 9 hours will be enough to complete the "Initial Block Download" (IBD). This may fill up your drive a bit, but again, on most new machines, 300 GB of space isn't that hard to come by.

Tech Skill Level: 1 (encrypted wallet)

One thing we left out in the level-0 exercise is encrypting your wallet. It's easy enough to do well, but a bit more difficult to do right. The main challenge is that humans generate really poor passwords. If you want a good password, the best way is to use something called "diceware". Basically, you just grab 4 or 5 dice and each throw of the dice represents a certain word on a special list. The throw {1,4,5,3,1} for example would be the word camping on the EFF-diceware-wordlist. So you repeat this a few times until you have a list of 8 or so words which becomes the passphrase you use to encrypt your wallet. Write it down, it is always hard to remember at first. So at level-1 your list becomes:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Choose Encrypt Wallet from the Settings menu
  5. Enter your 8 word (or so) passphrase generated using the Diceware method

Wallet Encryption Dialog

Tech Skill Level: 2 (enable pruning if needed)

Though I said "300 GB of space isn't hard to come by", some times it actually is. If space is an issue, a simple way to fix it is to tell bitcoin to simple take less space. This is called "pruning" and can take that number from 300 GB down to below 5 GB. If you can't find 5 GB, then you'll have to read ahead to level-4 to add USB storage. But the good news is, enabling pruning is pretty easy, we just add another step to our working list:
  1. Download Bitcoin Core
  2. Launch the downloaded installer and install the app
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Choose Options from the Settings menu
  6. Choose Prune block storage to: and select the max size for the blocks to use
  7. Exit and restart the bitcoin application for the changes to take effect

Pruning Dialog
Note, even setting this to 1 GB will still leave you with about a 4.5 GB install. The blocks take up a lot of space, but the chainstate and other folders eat up at least 3.5 GB and they can't be pruned. Also, be aware, to disable pruning requires you to perform the entire IBD again. While pruned some other functions my be disabled as well, so just know that pruning does limit some functionality.

Tech Skill Level: 3 (verify the installer)

Although this is arguably something that should be done at level-0, some find the intricacies of comparing hash (thumbprint) values to be tedious and beyond the scope of a beginner. You will find these types of hash compares suggested quite often as a way to prevent running tainted programs. Programs are often tainted by bad disk or network performance, but most often, taint is malicious code inserted by viruses or malware. This is a way to guard yourself against those types of attacks.
What I cover here is a very basic comparison on the certificate, but a more thorough verification advised by mosts uses a program called Gpg4Win, and is beyond the scope of this beginners guide. But regardless, most users should strive to do this minimum level of validation.
  1. Download Bitcoin Core
  2. Launch the downloaded installer
  3. When prompted "Do you want to allow..." click Show more details
  4. In the details section select Show information about the publisher's certificate
  5. In the certificate window select the Details tab
  6. In the Details tab Subject should start with "CN = Bitcoin Core Code Signing Association"
  7. Ensure Thumbprint in Details reads ea27d3cefb3eb715ed214176a5d027e01ba1ee86
  8. If the checks pass, click OK to exit the certificate window and Yes to allow the installer to run.
  9. Launch the installed "Bitcoin Core" app and let it run overnight
  10. Do the wallet encryption steps here if you wish
  11. Do the optional pruning steps here if you wish

Certification Validation Windows
Note: The certificate used to sign the current Bitcoin installer is only valid from March 2020 to March 2021. After that point the thumbprint on the certificate will change. This is by design and intentional. If your reading this post after March 2021, then it is understood that the thumbprint has changed.

Tech Skill Level: 4 (use secondary storage)

We glossed over the "new machine with fairly good internet" part. Truth be known many people do not have fairly new machines, and find the IBD to take longer than the "over night" best wishes. For most people the slowdown is the disk access when calculating what is called chainstate. This requires fast random reads and writes to the disk. If you have an SSD disk, this will be no problem, but if you have a non-SSD "spinning" disk, random writes are always slow. Though an SSD will speed things up, they are pricey, so a nice middle ground may be a simple high-end USB key drive. You can get some with 10 to 15 MB/s random writes for $20 on Amazon. This is usually a order of magnitude faster than a "spinning" disk. And with pruning (see level-2), a small USB drive should be fine.
Once you decide on a drive, the tricky part will be to enable external storage. It requires editing a configuration file and adding a line. First, we want to create a directory on the key drive. You will need to determine the drive letter of your USB key drive. For the sake of this example, we will assume it is D:, but you must determine this yourself and correct the example. Once you know the drive letter, create a blank folder on the drive called Bitcoin. So for this example, creating Bitcoin on drive D: will create the path D:\Bitcoin. Once done, assuming that D: is your drive, here are the new steps including the edit of the configuration file:
  1. Download Bitcoin Core
  2. Launch the installer, verify it, then run it
  3. Launch the installed "Bitcoin Core" app and let it run overnight
  4. Do the wallet encryption steps here if you wish
  5. Do the optional pruning steps here if you wish
  6. Launch "Notepad" by typing "Notepad.exe" in the windows search bar then click Open
  7. Type the line datadir=D:\Bitcoin (depending on your drive letter) in the blank file
  8. Choose Save from the File menu in notepad
  9. Type %APPDATA%\Bitcoin\bitcoin.conf (note the percent signs) in the File name box
  10. Select All Files from the Save as type dropdown
  11. Click the Save button and overwrite the file if prompted
  12. Exit and restart the bitcoin application for the changes to take effect

Save As Dialog
Now that you've reached this level of technical expertise, there are many new configuration options that you can begin to modify if you wish. Most configuration data is contained in the bitcoin.conf file and learning how to maintain it is a key step for a node operator.

Tech Skill Level: 5 (all other customizations)

Here's a short list of various things you can ADD to your bitcoin.conf file. You generally just add a new line for each configuration settings.
  • addresstype=bech32
  • changetype=bech32
The addresstype / changetype allows your wallet to use the native-segwit (bech32) format. This is the most efficient and inexpensive way to spend bitcoin, and is a recommended configuration. The default uses something called p2sh-segwit which is more compatible with older wallets, but more expensive to spend.
  • minrelaytxfee=0.00000011
Changing the minrelaytxfee setting allows you to help propagate lower fee transactions. It will require more memory but TXN memory is capped at 300 MB by default anyways, so if you have enough memory, it is a good setting to choose.
  • dbcache=2048
The dbcache setting controls how many MB of memory the program will use for the chainstate database. Since this is a key bottleneck in the IBD, setting this value high (2048 MB) will greatly speed up the IBD, assuming you have the memory to spare
  • blocksdir=C:\Bitcoin
  • datadir=D:\Bitcoin
In level-4 we discussed moving the datadir to a fast external storage, but the majority of the space used for bitcoin is the blocks directory (blocksdir). Although you should always use for fastest storage for datadir, you are free to use slow storage for blocksdir. So if you only want to consume a small amount of your SSD (assumed D:) then you can keep your blocks on your slow "spinning" drive.
  • upnp=1
One of the harder challenges you may face running a node, is to get incoming connections. If you are lucky, you may find that your firewall and network HW support the uPnP protocol. If they do, this setting will allow bitcoin to configure uPnP to allow incoming connections to your node. Other methods exist to make your node reachable, but they are well beyond the scope of this guide.

BCH blocks needs to be able to process 6.7 GB blocks in order to collect the same fee as BTC on average while guaranteeing that 0-conf would function during the biggest shopping days

  1. We assume that 0-conf is the method for fast transactions.
  2. For 0-conf to function well transactions must be included in the next transaction almost always. If it doesn’t a fee market is developed making 0-conf to expensive.
  3. In order for BCH to generate as much money to miners through fees as BTC the BCH blocks needs to be 850 times bigger than the BTC blocks, because BTC transactions are 850 times more expensive than BCH. This number was taken from coin.dance just now.
  4. BTC blocks are 1.21MB in size. This number was also just taken from coin.dance just now.
  5. VISA has an average of 1700 tps currently.: In 2011 the peak load for VISA was 11 000 tps. . This is comparing an average from 2019 with a peak in 2011. The peak is likely higher now but these are the numbers I could find. It gives us that the ratio of max/average conservatively estimated is 11000/1700 = 6.5 times higher than the average.
Now we can make a few calculations.
a. the average BCH block size needs to be 1.21MB * 850 = 1028 MB to collect the same fees that BTC is collecting today. b. In order for 0-conf to work reliably the max block size needs to be 6.5 times bigger than the average.
This means that BCH blocks needs to be able to process 1028 * 6.5 = 6.7 GB blocks in order to collect the same fee as BTC on average while guaranteeing that 0-conf would function during the biggest shopping days.
Please note, this is a reasoning about profitability and function. Not about how much transaction capacity that is needed.

A Bitcoin transaction Now that you have created your public/private key pair, you are ready to join the network and receive bitcoin. Your friend, Tom, said he is willing to give you 10 bitcoin if ... Overview of a Bitcoin Transaction. To better illustrate how value is transferred in the Bitcoin network, we will walk through an example transaction, where Alice sends .05 bitcoin to Bob. At a high level, a transaction has three main parts: Input. The bitcoin address that contains the bitcoin Alice wants to send. How a Bitcoin Transaction Works. In contrast to banking, a bitcoin transaction is simpler. To send bitcoin, you need a bitcoin wallet, which lets you store bitcoin, send bitcoin, or receive bitcoin. You also need your recipient’s bitcoin wallet address. Bitcoin users cannot split a transaction into smaller amounts and only the entire output of a transaction can be spent. So, when you open your wallet and type, ".25" in the amount field what technically happens is that one of the .5 BTC transactions (from your generous friend, Chris) will be sent, in its entirety. Let’s understand the mechanics of a real bitcoin transaction. We’ll use the image above as a reference. If you were to cut open a typical bitcoin transaction, you’d end up with three major pieces: the header, the input(s), and the output(s). Let’s briefly look at the fields available to us in these sections, as they’ll be important ...
