Dear Crypto Community & Privacy Advocates, This is an urgent call: My trial begins July 14, and we’re facing a critical shortfall. I need to raise $500K in the next few days and $1.5M within a couple of weeks to sustain our fight - covering escalating legal fees, expert…

Dear Software Community, 🚀🔒 It's Roman Storm here. As my trial begins on July 14, we're facing an unexpected hurdle: ⚠️ What started as a planned 2-week trial is now expected to last 3-4 weeks due to complex legal arguments and unforeseen witnesses and evidence. This means…

🧰 Too much bitcoin tech knowledge is trapped in videos and podcasts If only there was an easy way to unearth those insights and gems… 🤔 We wondered that too, so we redesigned Bitcoin Transcripts! 🚀

Block 904,864 today was a prime example of why Bitcoin Core supports relaxed relay policies. This block contained many consolidation txns that paid under the standard 1 sat/vb fee rate and thus were not relayed. It resulted in far slower block reconstruction & thus propagation.

Java joins the bitcoinkernel language bindings family!

yyuvicc@hey_yuvicc · Jul 7

Enough of C++ & Rust, now we can use @bitcoincoreorg consensus engine using Java as well. I've created a Java wrapper library that leverages the C API from the libbitcoinkernel project!! Check it out here, github.com/yuvicc/java-bi…

I need help! I've been stuck on getting @Boltzhq refunds/claims to work in my iOS @getbittr app. Are there any Swift developers with bitcoin/Musig experience in my timeline? RT for visibility would be appreciated! 🙏

😔💔 I’m Roman Storm. I poured my soul into Tornado Cash—software that’s non-custodial, trustless, permissionless, immutable, unstoppable. In 31 days, I face trial. The DOJ wants to bury DeFi, saying I should’ve controlled it, added KYC, never built it. SDNY is trying to crush…

I would much rather stay out of this, but I do have to say the following: I think spamming the Bitcoin blockchain with NFTs is dumb. I think many of the people doing it are either dumb or malicious. Yet, I defend everyone's right to use the blockchain as they wish as long as…
