The Shortening Replacement Cycle and Crypto

The author argues that crypto turns many finance and fintech problems into coding problems, which coding agents now make easier to solve. The post cites Vitalik's claim that Ethereum has become a high bandwidth network without sacrificing decentralization or consensus, enabled by zkEVMs, and says Opus 4.5 is the technical leap that convinced the general public about coding agents. It gives examples such as using crypto-economic incentives for running nodes, audited smart contracts for guaranteed payment, and Uniswap v4 hooks for liquidity. The author also says they stopped using no-code tools like n8n and Langflow for agent building in favor of coding in Cursor or Windsurf, because AI can't help build no-code pipelines and those pipelines aren't portable.
