When Taproot?

When Taproot? is a cool new site promoting adoption of taproot. It examines the stages of adoption for wallets, exchanges, and other services, why taproot adoption is a good thing, and how you can help.

BIP 351

BIP351 is a stealth address protocol that makes it possible for two parties to transact using addresses that only they can calculate. It’s an improvement over BIP47 because it takes measures to conceal the initial notification transaction. However, it still suffers from some of the same drawbacks: the sender must exercise coin control and it requires an on-chain transaction before any payments can be made.



CLN Channel Splicing Draft PR

Dustin Dettmer has opened a draft PR to enable channel splicing on CLN. There is a long list of TODO items to get this PR across the finish line but this feature represents a massive improvement to LN usability.

Lightning Labs has released the taro daemon alpha. Despite what the name might imply the taro daemon is not a little monster that steals your root vegetables, it is a tool to issue and transfer assets on bitcoin and lightning.

Onion Messages and Asynchronous Lightning Payments

LDK developer vallywal explains how onion messages not only unlock bolt12 offers and blinded routes, but the combination of onion messages and PTLCs enable async payments over lightning that don’t lock up network liquidity. Really tho, the awesomest part of this blog post is all the 🔥 diagrams.



Buy and sell bitcoin privately and securely on a Bisq’s peer-to-peer network.


Payjoin is a type of coinjoin where merchant and buyer create a coordinated transaction. Coordination happens with PayToEndPoint [P2EP] concept. PayJoin obfuscates the amount of the transaction and breaks the common ownership heuristic. If the payjoin fails it will fallback to an ordinary transaction. It has the additional benefit of allowing the merchant to consolidate UTXOs.


ln-vortex is a tool written in scala that allows coinjoin lightning channel opens. Ben Carman and @deregs_ just opened the first mainnet vortex coinjoin.
