Re:Show HN: We put ZK attribute proofs inside x402 payment headers on Tuesday April 28, 2026 @12:33PM (#47936747)

One note on the MCP server we also shipped (github.com/lemmaoracle/lemma/tree/main/packages/mcp):

x402 is already agent-callable at the protocol level, so no MCP wrapper is needed for payments. The MCP server exposes the read side of the same trust layer (query verified attributes, get schema, get circuit, get generator, get proof status) for agents in MCP-native environments (Claude Desktop, Cursor, etc.) that want to read from Lemma without a custom REST integration.

Two surfaces, one trust layer: x402 : payment rail + ZK proof bundle in PAYMENT-RESPONSE MCP : read interface for MCP-native agents

Every x402 settlement in this repo carries a ZK proof bundle in PAYMENT-RESPONSE: issuer identity, payment settlement, and data integrity, independently verifiable. Live on Base Sepolia.(Recap: x402 is Coinbase's revival of HTTP 402. Server returns 402, client signs an EIP-3009 USDC auth on Base, retries with PAYMENT-SIGNATURE, facilitator settles.

Re:The New Way to Monetizing OSS by Using Token Economy on Monday September 03, 2018 @08:20PM (#17905716)

Large projects can monetize in other ways. It's best for small but technically essential libraries. e.g., like vue-xxx, rollup and moment. By issuing a new token, it is possible to monetize without changing the license while keeping OSS free.( https://medium.com/devtoken/dev-tokens-for-oss-a63e55c60e6b )

Re:TypeScript at Google on Monday September 03, 2018 @10:48AM (#17902847)

I switched from Flow to TypeScript. Flow has some type-declared libraries, but it's fewer than TypeScript type-declared libraries. The excellence of VSCode also helps me.

OSS's sustainability has a significant challenge. I think the token economy might solve it. I started experiments with npm. https://devtoken.rocks/alpha/en

Server-less functions will be thinner when launched new managed services like AppSync.

So cool! It covers common use cases, and maybe I will use it.
