Replace vague "Ed25519-derived peer identifier" with the precise construction: SHA-256(TL constructor 0x4813b4c6 little-endian || Ed25519 public key). Matches the reference implementation in ton-blockchain/ton (keys/keys.cpp::compute_short_id) and the TL schema pub.ed25519.

There was a problem hiding this comment.
I haven't had a close look, but it sounds reasonable and enough context was provided. It's also in a high byte range, hence approving it.

Add multicodec namespace entry for TON ADNL addresses in the 0xbX9910 range following the existing namespace convention (alongside skynet, arweave, subspace, kumandra, massa).
What is ADNL?
ADNL (Abstract Datagram Network Layer) is TON's peer-to-peer networking protocol. An ADNL address is a 32-byte identifier computed as
SHA-256(TL_constructor_id || pubkey), where the TL constructor id forpub.ed25519is0x4813b4c6serialized little-endian (wire bytesc6 b4 13 48), followed by the 32-byte Ed25519 public key. Reference:ton-blockchain/ton—keys/keys.cpp::compute_short_id().https://docs.ton.org/develop/network/adnl-udp
Codec added:
│ 0xb69910 │ adnl │ TON ADNL address: 32-byte SHA-256(0x4813b4c6_LE || Ed25519-pubkey)
Motivation
This codec enables ENSIP-7 contenthash encoding for TON sites, allowing
.ethdomains to resolve to TON resources through standard content-addressed URIs.Reference implementation: https://github.com/TONresistor/Tonutils-Proxy/blob/contenthash/resolver/contenthash.go
Live example: tonnet.eth contenthash set on Ethereum mainnet
