• Why Full-RBF Makes DoS Attacks on Multiparty Protocols Significantly More Expensive
• Version Handshake Bitcoin core developer Bruno Garcia has published an excellent technical dive into the version handshake. Sometimes referred to as “the dance”, this is the process by which a bitcoin node introduces itself to another node to begin sharing p2p data.

1. Route Blinding Vanilla lightning payments have great privacy properties for the sender of a payment, but quite bad privacy for the recipient. Route blinding is a proposal to fix this gap. It works by having the payment recipient conceal the last few hops of the payment route using cryptographic blinding. And after 2.5 long years it’s almost ready for use in the real world!

2. Opening and announcing a pre-taproot LN channel Elle Mouton drops another 🔥 blog post chock full of diagrams all about the steps required to open a lightning channel today (pre-taproot).

Miscellaneous

• Bitcoin technical search
• Mempool block audit view
• Ordinal Inscriptions: NFTs on bitcoin. ordinals.com is a site to browse ordinal inscriptions, a new NFT scheme built on bitcoin by SF BitDevs host @rodarmor. Ordinal theory is a scheme to number and track every satoshi based on its issuance date. Inscriptions are a scheme to associate on-chain metadata to a single satoshi ordinal. The data is stored in the tx witness script, leading to heated debates about whether inscriptions are a good or bad thing. The debate is sure to heat up after this absolute unit of an inscription took up almost an entire bitcoin block.
