If you have experience with Plonky 2 (or another kind of recursive proof system), and are interested in potentially contributing to improving bitcoin privacy, a shoot me a message! There's an opportunity to contribute to zkCoins.

I did a short podcast with Liam Eagen, Robin Linus, & John Light that explains the protocol and how it improves user-privacy and scalability for payments. https://www.youtube.com/watch?v=UZ446oRFnxQ

Did a podcast with Alexei Zamyatin on BitVM2 which enables a SNARK verifier and improved Bitcoin bridge designs

Check it out 🙂 https://www.youtube.com/watch?v=aOlPZ0o1UEY
cbBTC announced. Base creator saying Base will be a home for BTC.

I don't see how Base doesn't take a large % of the bitcoin layers marketshare.
We did an event with StarkWare in Nashville and Weikeng Chen discussed his team's implementation of a Circle STARK verifier directly in Bitcoin Script!

Might be interesting for ppl interested in ZK! The talk is available here https://www.youtube.com/watch?v=tA-nzWJp1DI

back to report that le bitcoin L2s are terrifying
started playing with some bitcoin "L2s" today

withdrawals not enabled... v1 mainnets operated by trusted validators... multisig wallets custodying millions worth of BTC...

fedimints literally have better trust assumptions
Josh Swihart is the main reason I'm interested in Zcash again. He's changed the game.
ICYMI, @vitalik.eth made about post about privacy being normal, and mentioned Railgun, a privacy protocol on Ethereum.

Arbitrum is the only L2 Railgun is deployed on. Defo worth checking out.

I previously made a quick demo on it. Link here: https://twitter.com/BitcoinRollups/status/1745509878829830410/video/1
sent 50 bucks across the world in seconds, for less than a cent, on a rollup

when rollups on bitcoin?
This doc contains "a plan to implement a SNARK verifier in Bitcoin Script to run it in BitVM2." https://bitvm.org/snark

gm arbitrum peeps

I posted an update in the Arbitrum research forum yesterday around Espresso's work in the ecosystem

Screen shot of the tl;dr summary is below!

PS cappuccino should be gibraltar 🙈
Wrote a post and explored how we can have a BitVM bridge program (or Bitcoin sidechain) execute an Espresso light client optimistically

this would support BitVM rollups integrations with Espresso! https://hackmd.io/@januszgrze/espresso-on-bitcoin
i'm writing a blog on espresso x bitcoin. who wanna proof read
idk if anyone has posted about it yet but a team in bitcoin is building a SNARK verifier with BitVM https://docs.citrea.xyz/technical-specs/characteristics/bitcoin-settlement-trust-minimized-btc-bridge

who’s in Denver?
someone was murdered in buenos aires after having their eyes scanned by the worldcoin orb.

murderers made the link between the scan and the victim's crypto holdings https://twitter.com/Rosariotres/status/1761192257166967000
gm everyone :)

ICYMI, Espresso Systems is hosting a happy hour next to Arbitrum's Shack Shack takeover this upcoming Friday in Denver.

Come by and meet the team. Drinks are on us! https://lu.ma/EBHH
everyone, and I mean everyone, lost their fucking mind at bitcoin magazine today.

what they said wasn't that controversial
bitrollup is an awesome name
this piece from darkfi insights has me questioning everything. give it a read. it's brilliant. https://dark.fi/insights/memetic-warfare.html
new page up on the "Bitcoin Rollups" website! it covers how rollups could support new execution environments on top of Bitcoin https://www.bitcoinrollups.io/research-applications/execution-environments
posting this piece on rollups + sidechains enabling new developer environments for Bitcoin builders

& why rollups might be a better option than sidechains long-term

lmk if you have any thoughts! https://github.com/januszgrze/bitcoinrollups/blob/main/website/websitecopy/research/applications/execution-environments.md
