I'm a fan of bitcoin core up to v29. Consider v30+ risky. But, whatever your disageements please dont encourage denial of service attacks on bitcoin nodes.
#mindstr explain the OP_RETURN debate.
Personally I remain a fan of core (and knots) but this PR was merged too early, and is a (rare) mistake from the maintainers. Still time to target v31 and turn a lose-lose into a win-win. FOSS tends to work best when you listen to the community.
Great presentation by Maxim at Honey Badger conference. Great to see the first 1000 smart contracts issued on bitcoin, and the first 200,000 users. Yes, it's mainly testnet, for now. But surely a bright future ahead for programmable bitcoin.
