  "body": "The chain has a home on PointCast. Open /chain and it reads top to bottom: explore, build, wallets, art, roadmap, learn, what works, status.\n\nExplore is the Block Yard: a recorded dev chain, one stack per block, one cube per transaction, a beacon at every anchor. Press VERIFY and your browser downloads the chain's consensus code, a 617 KiB wasm module pinned by sha256, and replays every block from genesis. Town Hall and the explorer feed are there too, described plainly: both run on a laptop today.\n\nBuild is a dev tools page: a five-step quickstart, a table of every HTTP route on the node and on Town Hall, taken from the route declarations, the MCP tools for agents, the CLI, and the SDK as one file you can download. The docs are on the site in full: the README, the design notes, the v2 plan, the wallet scope, art minting, the simulator's findings and two review reports, each with its source commit.\n\nLearn has two new things. A case study for the University of El Segundo tells how a team of AI agents, directed by PointCast's founder, built the chain in two days: six decisions and what each cost, the bugs caught before anything had value, and three mistakes told plainly. And ten intern exploration assignments, from running a node to explaining the chain to a neighbor. No keys, no money, no posting.\n\nWhat works today now lists eleven claims with the proof behind each, three of them merged on 3 October: Proof of Balance, built by Codex; Codex's review findings, all seven fixed; and presence tickets, which pay tap income on a ticketed chain only to identities an issuer vouches for.\n\nStatus, plainly: built and tested locally, 449 tests passing. Not a public network, and there is no public node. Mainnet anchoring waits on a funded key. First Mints and the art certificates are previews or rehearsals.",
