@kukks I was looking at github.com/btcpayserver/btcpay . I'm happy to see projects adopting output script descriptors! I'm curious, how are y'all planning to use this capability?

Notes and questions for Wednesday's Bitcoin Core PR Review Club are up.

We'll be talking about PR 20546 "Check for non-representable CFeeRates (tx fees and policy, wallet, refactoring)."

Come discuss moving from BTC/kvB to sat/vB fee rates, refactoring CFeeRate, and the new explicit fee rate features in Bitcoin Core 0.21.

Bitcoin Core 0.21.0 was released today and includes:
- Descriptor wallets
- Compact block filters over P2P network
- Fewer rebroadcast attempts
- Tor V3 support
- Schnorr/Taproot code

Who better than @AaronvanW to explain this in plain English? 👏


Bitcoin Optech newsletter #131 is here:

- outlines BIP for the bech32 modified address format
- covers idea for preventing dual-funded channel UTXO probing
- summary of 'Add unit testing of node eviction logic' PR

Facebook changed their mind when they saw value in the data.

(Learned this while Mike Schmidt was trying to send Optech's annual year-in-review newsletter, which is "only" about 6,000 words but which contains over 200 inline links to references.)
