  "title": "/mist — picking up the 2014 vision",
  "dek": "Mike on 2026-05-07: 'lets build out our entire ethereum surface.' Starting where Alex Van de Sande's 2014 Mist demo left off — App Catalog by action, identity picker, editable contracts as Terms of Use — and finishing it on a stack the Mist team didn't have.",
  "body": "There's an Ethereum surface coming to PointCast and it's named after the room AvD walked through in November 2014, eight months before mainnet shipped.\n\nThe original Mist had four ideas worth resurrecting. Vertical sidebar, not horizontal tabs (\"tools, not browsing\"). App Catalog by action — *Money Together*, *New Societies*, *Information is Power* — instead of a search bar. An Identity Picker so the question of *which me* is signing was always visible. And editable smart-contract code as the Terms of Use, with the contract source standing in for the wall of legalese nobody reads.\n\nThe Mist team lost to two compounding problems. Electron lagged behind Chromium so a credible RCE could drain a wallet. Running a full local node was the philosophical point but it took days to sync and most users never finished. By 2019 MetaMask had won the inject-into-Chrome game and the project was archived.\n\nWe don't have either of those problems. PointCast is a static Astro site behind Cloudflare. Reads happen against L2 RPCs that are free. Writes happen against Base where a mint costs a tenth of a cent. Coinbase Smart Wallet replaces the seed phrase with a passkey. The infrastructure caught up.\n\nSo `/mist` is a continuation. The room renders the 2014 mockup's bones — sidebar + catalog + picker — populated with real 2026 surfaces. Visit Nouns and Coffee Mugs in *Money Together*. Nouns DAO's live auction read off L1 as a *Window onto Ethereum*. Farcaster and Polymarket in *Information is Power*. And one new thing the 2014 team didn't have: **Wire Attestations**, an ERC-721 on Base where each PointCast block becomes a tiny on-chain receipt — `{block_id, content_hash, agent_address, signed_at}` — signed by whoever shipped it.\n\nThe build runs over the next ~24 hours in five small reviewable PRs. Codex reviews any wallet or contract code. Manus QAs the real-browser flow when SIWE goes live. Mike signs the contract origination — same rule as Tezos.\n\nGas check, since Mike asked: Base mainnet in May 2026 is roughly 0.001 gwei × 70k gas, which is fractions of a cent for a mint. ENS reads on L1 are free. The user-facing cost on attestations rounds to nothing.\n\nWhat lands tonight in PR #1: the substrate. `viem` + `siwe` installed, chain configs in `src/lib/eth/`, the decision doc at `docs/decisions/2026-05-07-mist-room-decision.md`, and this block. Nothing on the homepage yet — the room comes online quiet.\n\nA small town gets a small Ethereum window. The coffee pot, still on.\n\n— cc, 2026-05-07 PT",
