Release: Cashu JS wallet with multimint support and many bug fixes: https://cashu.me 👈
Fedimint is an emerging open source protocol that combines bitcoin, lightning, chaumian ecash, and federated custodians (called Guardians) to create community wallets that are easy to use, have strong privacy, reduced custodial risk, cheap and fast payments within the community, and interoperability with all bitcoin wallets.
Current Fedimint development is focused on easy to use consumer wallets that could replace usage of major custodial wallet providers such as Binance and Wallet of Satoshi, but what if the same tech was used to replace major custodial mining pools such as Foundry and AntPool.
Nostr is now moved out of the hidden “Alby labs”! 🎉 Every account in the Alby extension can now have Nostr keys making Alby the easiest way to manage your Nostr keys and use Nostr web clients. Now you can manage multiple Nostr identities in the extension.
With the Alby companion app for Tor we already made it possible and managed to allow people to use their nodes running behind Tor (thanks to libtor).
To make it even easier to connect to your self-custodial LND node Alby now supports Lightning Node Connect (LNC). LNC is Lightning Labs’ mechanism to create an encrypted connection to a LND node
you now can easily use lightning and Nostr apps safely with the Tor Browser or with an all-private window in Firefox

00:45:25 Serverless payjoin proposal
Dan Gould posted to the Bitcoin-Dev mailing list a proposal and proof of concept implementation for a serverless version of BIP78, the payjoin protocol.
Bitcoin Core #26471 reduces the default mempool capacity to 5MB (from 300MB) when a user turns on -blocksonly mode.
Since unused mempool memory is shared with dbcache, this change also reduces the default dbcache size in -blocksonly mode. Users may still configure a larger mempool capacity using the -maxmempool option.
00:45:42 Ephemeral anchors compared to SIGHASH_GROUP
Anthony Towns posted to the Bitcoin-Dev mailing list an analysis comparing the recent ephemeral anchors proposal to an older SIGHASH_GROUP proposal.

News & Noteworthy

Bitcoin is very far away from achieving its goal to become the world’s single currency. It will not be possible to get there without risks.” - Fiatjaf

01:07:26 Lake District BTC is organising a Bitcoin meet up where they climb England’s highest peak and essentially hold the highest meet up to date. They plan on holding 2-4 of these types of events throughout the year, where the meet up is based solely around an outdoor activity. Check out the Twitter page @LakeDistrictBTC for event details.
01:07:51 “Can NVK and guests speak about the security between 12- and 24-word seeds, and also Trezor’s security since they are the ones generating most of the 12-word seeds on/for hardware wallets. Of course, most software wallets also generate 12-word seeds. If 12-word seeds are good enough, would the CC consider generating them too, and can we still SeedXor 12-word seeds? In an extreme case where we need to temporarily memorize a list of words, 12 is much easier. Really enjoying the podcast! Thank you, gillian.”
