Add Animica namespace (animica:1) — CAIP-2/10/19

[animicaorg]

Summary

This PR adds the animica namespace with CAIP-2, CAIP-10, and CAIP-19 profiles.

Animica is a live proof-of-work Layer 1 whose accounts sign with post-quantum ML-DSA-65 (FIPS 204) signatures and whose smart contracts run in a Python VM. Mainnet has been running since 2026-04-06 (chain id 1, genesis 0xa0892158cf997c56e91d0aa12e60c36037dae34800a2b54111a8fa17ec88b7de). The native token ANM has 9 decimals.

Motivation

The identifier animica:1 is already in production use today: Animica's x402 ANM settlement lane uses it as its network id, as do its MCP tooling and chain parameters. This is the same situation as the bsv (#190) and kaspa (#193) submissions, where a payment protocol was already exchanging a CAIP-2 identifier and the namespace registration documents it. Wallets and dapps integrating Animica need CAIP-2/10/19 identifiers they can rely on rather than each inventing their own.

Animica cannot live in eip155: it is not an EVM chain, its addresses are bech32m strings carrying a signature-scheme id and a SHA3-256 key digest, its transactions are canonical CBOR signed with ML-DSA-65, and its chain id 1 would collide with Ethereum mainnet.

What each document defines

• animica/README.md - namespace overview, why it is not eip155, governance, and a resources list (website, explorer, public RPC, source, PyPI, normative HD-derivation doc, exchange listing).
• animica/caip2.md - animica:<chainId>; reference is the canonical decimal of the node's uint32 chain id (^(0|[1-9][0-9]{0,9})$, bounded to uint32, 0 unassigned). Resolution via chain.getChainId, and a genesis-hash cross-check via chain.getChainIdentity (live response included) so a future chain reusing the id cannot be mistaken for mainnet. Valid/invalid test tables. animica:2 (testnet) and animica:1337 (devnet) are noted as reserved; only mainnet is public today.
• animica/caip10.md - animica:1:anim1...; the native address is bech32m (BIP-350, HRP anim, constant 0x2bc830a3) over a 34-byte payload u16be(alg_id) || SHA3-256(pubkey). Always 66 characters; ML-DSA-65 accounts (0x1003) start anim1zqp, contract addresses (0x0000) start anim1qqq. Lowercase is canonical. Regex ^anim1[02-9ac-hj-np-z]{61}$ plus checksum/length/alg-range validation. Test vectors are the three real addresses from the BIP-39 reference mnemonic in the normative HD derivation document, plus negatives (mixed case, uppercase, plain-bech32 checksum of the same payload, corrupted checksum, bare hex digest).
• animica/caip19.md - native asset animica:1/slip44:4279885 (coin type 0x414E4D = ASCII ANM, 9 decimals). SLIP-44 registration is pending (a PR to satoshilabs/slips is being filed alongside this one). Contract-issued tokens are explicitly reserved for a future revision rather than specified loosely.

How it was verified

• Frontmatter of all four files parsed with PyYAML; every [Name][] alias resolves and none is unused; no inline external links; one sentence per line.
• Every CAIP-10 test vector was re-derived independently in Python: SHA3-256(pubkey) matches the published digest, bech32m encoding of 0x1003 || digest reproduces each address byte-for-byte, each decodes with the bech32m constant to a 34-byte payload with alg_id = 0x1003, and each matches the regex. Each negative vector fails for exactly the stated reason (the plain-bech32 variant verifies under constant 1 and fails under 0x2bc830a3).
• Every CAIP-2 and CAIP-19 valid/invalid identifier was checked against the profile regexes and the uint32 bound.
• The chain.getChainId, chain.getChainIdentity, and state.getAccount responses shown in the profiles were captured live from https://rpc.animica.org/rpc on 2026-08-22.
• bundle exec jekyll build was not run: Ruby/Bundler are not available in the authoring environment. The pages use only the same frontmatter keys as the existing neo, bsv, and stellar profiles, and the site auto-discovers the animica/ directory.

Known limitations

• The SLIP-44 coin type 4279885 is not yet in the registry; the CAIP-19 profile says so.
• Contract-token asset references are deliberately out of scope for this revision.
• discussions-to points at this PR, following the precedent of bsv, stellar, and xync.

@bumblefudge @obstropolos when you have a moment, an editorial review would be much appreciated - thank you.
