Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Help finding the code

Hey guys, Shadow here. So I have been banned from BitcoinCashNode/BCHN slack after ~3 or 4 years of residency.
Yep, just a suggestion/comment in the config file here which showed me 'this was useful for me, let me share it' kind of vibes. I also checked their history there. Seem to be helping review things too (i have no idea about the back story here, just going on what I'm seeing before me)

What is the technological case for BCH?
They're already implemented and running on testnet4, using node software built from this MR: https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node/-/merge_requests/1600

Main reasons why I am NOT leaving Bitcoin Cash
Either build the test branch yourself (https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node/-/merge_requests/1600) or use Calin's build here (https://www.c3-soft.com/downloads/BitcoinCash/testing/mr-1600)

Commands to strip Bitcoin & BCHD executables
At first I was disappointed by the results following official build instructions for BCHN (here) & Bitcoin Core (here), but eventually I realized they were missing the strip * command. BCHN gave a strange warning when running it, but that issue is apparently resolved with the -DCLIENT_VERSION_IS_RELEASE flag. Without stripping, the bitcoin-qt.exe can be 415 MiB instead of under 31 MiB.
- BCH, yes it's fast, but fast to zero confirmations?

I'm terribly sorry. As the noob that I am, I have previously stated that the latest RPi4 can process Scalenet's 256MB blocks in just under ten minutes. I was wrong.

Docs plz
BCH runs by a diverse set of node implementations that have slightly different implementations (and docs), although following the same consensus rules. I would recommend starting with BCHN's list of consensus changes since the hard fork in 2017: https://gitlab.com/bitcoin-cash-node/bitcoin-cash-node/-/blob/master/doc/bch-upgrades.md

Why Doesn't BTC Implement 0-conf?
A draft implementation is coming to testnets for BCH via Bitcoin Cash Node hopefully soon.

AnyHedge is UTXO DeFi Derivatives Contract Template for Bitcoin Cash and I Scraped On-chain Data for Total Settled Volume
It is non-custodian betting on price of supported assets paired against BCH, both parties put their money into the contract's pot and later the contract parses an oracle message and calculates how much they can take out. Made possible with Introspection opcodes and int64 upgrades to Bitcoin-tech Script VM, which activated in May '22 on Bitcoin Cash blockchain.
- What is the technological case for BCH?
- Is it there a continuation to the book “Mastering Bitcoin” but that explains the changes in BCH?

BCH May 15, upgrade, what benefits does it bring?
I dug around a bit and it seems to be this one: CHIP-2021-02-Bigger-Script-Integers.
-
What are your biggest criticisms towards the Lightning Network?
native introspection
- BCH Unlimited 1.10.0 now out. Let’s get ready for the May upgrade!
- I was hesitant to trust my BCH on the smartBCH chain but after a few days I'm sold! It is ALL the benefits of ETH's smart contracts and ALL the benefits of Bitcoin in one! Just one question...

Introducing Unforgeable Groups for Bitcoin Cash - Using Groups as Owners
The latest "Group" proposal (v4.2) is more than just "tokenization". It got simpler and more powerful at the same time. It now enables generic BCH output groups that can be used to create persistent Script covenant contracts that can prove their genuineness. This is something that current contracts cannot do, even with the new Introspection opcodes. Group would make it possible because the groupID is a commitment to the whole genesis transaction, but this is not a post about that.

Coming soon to Pokket.cash: SmartBCH support!
Will you soon shut up about BCH being shit against "superior chains" when I point you to the CHIPs such as Native Introspection Opcodes, Bigger Script Integers which allows better smart contract functionality coming in 2022, and PMv3 and Group Tokens which allow better token and transaction formats that are coming in 2023?
-
Introspection opcodes are so cool, here's a teaser
You can't, because it requires a sibling output (same prevout txid as the contract, but index 1 instead of 0) to be spent alongside it and it verifies it using introspection opcodes that will be available in May. Only the owner of the sibling can spend the contract.
