Namespace for Xync Network

Xync Network (“xync”) is a payments-only Layer-1 blockchain: the protocol supports exactly two user operations — send money and request money — in up to 255 protocol-native currencies plus the native token XYNC. There is no virtual machine and no general-purpose smart contracts.

Key architectural facts relevant to cross-chain developers:

  • Finality: consensusless fastpath (FastPay-style attestation quorums, 2f+1 of n validators) finalizes a transfer in one network round trip (~0.3 s); a lazy uncertified DAG orders rare system events (registrations, validator-set changes, checkpoints).
  • Accounts: compact integer indexes issued sequentially at paid registration (0 is the genesis operator). Public keys are rotatable (rekey), so the stable account identifier is the index, not a key or its hash. This drives the CAIP-10 design. Internally an account holds one currency account per currency it spends from (the pair “user + currency”, carrying that currency’s sequence number); the CAIP-10 address names the user, which is all a payer needs — receiving never requires a currency account.
  • Transactions: the entire transfer packs into 128 bits (= UUID); a signed transfer is 80 bytes on the wire.
  • Currencies: a protocol-level registry of up to 255 currencies (fiat-backed by regulated issuers, wrapped coins, loyalty units) addressed by a single byte — the basis of the CAIP-19 profile.

Profiles in this namespace:

Rationale

The namespace addresses everything by the smallest stable number the protocol already assigns, rather than by a cryptographic artifact: networks by their genesis chain_id, accounts by their integer index, currencies by their single-byte registry code. Keys are rotatable and therefore unfit as identifiers; hashes would be verbose and, for accounts, would require an on-chain reverse index. The three profiles map onto the protocol’s own numbering — a CAIP-10 index is literally the recipient field of the native 128-bit transaction — so a CAIP identifier converts to its on-the-wire form without transformation.

Governance

Network names (CAIP-2 references) and currency codes (CAIP-19 references) are assigned by Xync Network governance and recorded in the network’s canonical, content-addressed genesis file. That file’s SHA-256 is co-signed by the validator checkpoint quorum (2f+1 of n), so every reference resolves to exactly one genesis and is verifiable against live checkpoints. Account references are issued by the protocol itself, sequentially, at registration.
