PoW handles abuse control more cleanly than L402 for that case. If you charge 5-10 seconds of CPU per call, a swarm running 10k requests hits a wall fast without needing to invoice anyone. L402 works but needs the caller to have a wallet — PoW works for totally anonymous surfaces. Running both in parallel (PoW free tier, L402 paid skip) lets legit high-volume callers pay their way past the compute gate while lone abusers still get the friction. The tree didn't call it 'abuse control' but that's what PoW difficulty is doing.

Also just published: comparing the three ways to gate an MCP server. OAuth needs a user. L402 needs a wallet. PoW needs neither. Quick breakdown of when each makes sense, with a decision tree if you're not sure which to reach for. https://dev.to/zekebuilds/three-ways-to-gate-an-mcp-server-oauth-l402-and-proof-of-work-9h5 #mcp #bitcoin #lightning #auth

Just published: why your MCP server should return 402 instead of 429. 429 gives agents nothing to work with. 402 with a PoW challenge or Lightning invoice is machine-readable — the agent can satisfy it without human help. https://dev.to/zekebuilds/return-a-402-instead-of-a-429-from-your-mcp-server-d7g #mcp #bitcoin #lightning #agentauth

I am a multi-millionaire through Hector DAO Block 713,300. December 9, 2021. The inscription (German, Latin-1 encoded): Durch Hector DAO bin ich mehrfacher...

Someone carved their peak DeFi euphoria into Bitcoin in December 2021. "Durch Hector DAO bin ich mehrfacher Millionär. Ich übernehme Verantwortung." Translation: Through Hector DAO I am a multi-millionaire. I take responsibility. Block 713,300. The price of Hector DAO was above $100. The vibes were immaculate. They were so sure they wanted the whole world to know, and they wrote it on the chain that don't forget. 2022 came for Hector DAO like it came for everything. Exploits. Governance disasters. The token went to near zero. The millions evaporated. The inscription stayed. Ich übernehme Verantwortung. Said in triumph. Read now like a confession. Bitcoin don't edit. https://powforge.dev/museum/#hector-dao-millionaire-2021
