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.

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?

- 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.

Please voice any opinions on points of failure for Cash Tokens here.
CashScript is similar to solidity, but writing contracts for UTXO chains is slightly different than for EVM chains since you don't have global state, just utxos.

Closest is probably cashscript. I believe they are currently working on these for the May upgrade this year

Announcing Unspent.app, an app for creating and calling anyone-can-spend contracts on Bitcoin Cash. Create or use faucets, minable contracts, annuities, perpetuities, or your own division and broadcasting contracts.
This app was built using the Cashscript route. So the contracts are written in a solidity style language and then transpiled to BitcoinScript. They're fast to write and easy to read, HOWEVER, if you step through the actual bitcoin script, you'll often see a number of things that are not optimal. There is a playground for CashScript: https://playground.cashscript.org/

Anyone know where to find the "idiot's guide" to libauth? Working examples would be nice
I should clarify that by examples I mean working code that can be run by itself as a demo. For example, the next.js repository has a very large collection of examples for integrating next.js with various tools and frameworks. You can also see these type of examples in the cashscript repository as well as in the bch-js repos
