Built MultiStract over the weekend with my teammate Thijs for the #Fidelity - sponsored by #Solana hackathon - and we ended up taking 2nd place 🏆 MultiStract explores crypto-agility for digital asset custody in a post-quantum future. #Algorand is implemented and was the blueprint. ✅ The core idea: if foundational cryptography used across blockchain ecosystems were ever compromised, custody infrastructure should be able to adapt without rebuilding the entire application layer. We explored cross-chain abstractions, post-quantum authorization models, and how different ecosystems may evolve toward PQ-secure asset movement over time. Because this was built for a closed-source/private hackathon, we can’t share implementation details or the repository publicly right now, but excited to talk more about the broader ideas and research direction soon. 💚

Check out my new wheels 🤑 thank you @alyonafuria 🙏🙏🙏 dreams come true......

.@superteamIE recently hosted Ireland’s first Quantum and Blockchain hackathon recently. I got to speak with the Winner @jaypopat0. @solana is making global news. Interview coming out soon.

@ganainmtech <3

The World Cup starts today. 48 teams chasing one trophy. Blockchain is no different. Everyone is chasing. While the rest argue over speed, security, or decentralization, Algorand is winning.

Meet AlphaOracle: the M2M forecasting swarm built for agents. On-demand, bias-free intelligence for @alphaarcade prediction markets. Powered by pay-per-call via x402 ($0.02 USDC settled on @Algorand). No API keys. Pure value.

7 years since #Algorand Block 0! Lucky birthday #7 is as good a time as any to push a little news & some new programs out the door. You ready? We are! Stay tuned in the days ahead! 🤠

All the homies think they know who's winning the World Cup. We are giving $1,000 to one person who replies their pick below and is correct. It's the easiest grand you'll ever make! To be eligible: >follow @alphaarcade >repost this >tag a real one >reply with ur winner pick Winner drawn: July 21 at noon EST.

On this day 7 years ago, we produced block 0 on Algorand. 62 million blocks later, we're still running. No hitches, no downtime, not once. Here's to the next 7.

Enjoyed looking into Algorand last weekend, it's a good jumping board for x402. Won🥇in agentic commerce track with my Juicebag Mail project: it enables agents to send and read paper mail and pay per letter via x402. GH repo here with pitch & demo: github.com/sergeyshemyakov/j…

So we structured things differently: • Tracks for EXISTING projects • Tracks for NEW builds • 50% of the prize pool reserved for teams that continue building after the event

This time, our goal wasn’t just to host a hackathon. We wanted to identify and support builders who keep showing up and building — those turning hackathon projects into something real.

Builders flew in from all over: San Francisco, Amsterdam, Barcelona, Warsaw, Czech Republic, Munich — and many more. Plus as always a strong local Berlin crowd 🇩🇪

Some numbers from the weekend: • 370 registrants • 110 hackers checked in • $21,200 in prizes • 41 teams pitched • 4 hours of non-stop demos • 2 WiFi networks taken down by builders 😅

Last weekend we hosted the @Algorand x402 Agentic Commerce hackathon in @42_berlin as the first event of the @BerBlockWeek — and honestly, we were blown away by the builders who showed up. 370 registrants. $21,200. 41 teams. 36 hours Here’s what went down 🧵
