We're doing trivia tomorrow at the Minneapolis Bitcoin Meetup! We will have a mixture of prizes, including a Bit Axe and a Minneapolis branded seed signer.

Welcome
Myself and other open source contributors are building a new Fedimint wallet.
It will support multiple mints, NIP87 mint discovery, and connecting to federations via Iroh. Ideally LN Address and NWC as well.
What should we name this wallet?
On the Fedimint dev call today, we setup a demo federation using Iroh.
Iroh is fucking awesome. It allows each Fedimint guardian to talk to each other via a relay, sets up P2P communication using hole punching, and uses public keys as identifiers (which allows the servers to change their actual IP address).
Everything can run behind a NAT on your laptop or home server. No domain names, no cloud servers, no open ports. It took us just 15 minutes to set one up with zero networking issues.
Distributed systems magic.
Minneapolis BitDevs is tonight at 5pm!
Not a developer? Not a problem. BitDevs is targeted for anyone that wants to further their understanding of Bitcoin. If you're going to hold Bitcoin, you might as well understand how it works
Where: Improving Inc
When: Tuesday Jan 14th, 5-7pm. Socratic Seminar will start at 5:30pm

Fedimint needs more wallets! No excuses anymore, the web SDK is here and is stupid simple to use.

Going to BitDevs instead of watching the Presidential debate was a fantastic decision
Yesterday at the Minneapolis Bitcoin meetup, we launched The Minneapolis Fed, which is a Fedimint for our community. I think this is one of the first mainnet community-lead federations and I'm excited to see more federations pop up over the coming year.
We on-boarded attendees using Fedi and @OpenSecret and even had a contest to see who could redeem a 100000 sat ecash note the fastest (shout out to Collin for winning).
Fedimint is still pretty early software so it was made clear that this is still somewhat #Reckless and to use with low value but given that v0.2.1 is the first stable release, we were eager to test it out with some real funds.
It was pretty cool to see federated ecash in action. I know we had an IRL ecash transaction for Real Bedford merch and some attendees reimbursed others for Keeper's Heart Old Fashions. Unfairly cheap too, our federation has no fees!
Given that this Fedimint is for the Minneapolis community, we will be keeping it small and mainly share invite codes during in-person gatherings. So if you want to try it out, be sure to attend a Minneapolis Bitcoin meetup or Minneapolis BitDevs
We are working on a guide that other communities can follow to setup their own federation. And over time this will get easier as we build tools to automate the deployment process.
Very fun meetup last night, thanks to everyone who attended and tried out Fedimint!

Mutiny + Fedimint is slick
Pretty big change to Fedimint got merged last week. We switched the consensus algorithm from HBBFT to AlephBFT. This change should improve the latency of Fedimint transactions and also eliminates a lot of redundant code. Shout out to joshican for getting it merged!
