Releases

v0.1.0 - 2026-11-12

First release of xOne, the Rust client for XDC Network. The workspace version is 0.1.0.

Client. Rust crates for primitives, chainspec, consensus (XDPoS V1 and V2), EVM, state,
executor, database, networking, snap sync, node, RPC, signer and block builder. One binary, xone.
The version stamp (xOne/v<semver>-<commit8>-<DDMMYYYY>/<os>-<arch>/rustc<version>) comes from one
function that xone --version, web3_clientVersion, the P2P hello and ethstats all use.
Sync modes. Full, snap, fast (an alias of snap, as in geth-XDC), minimal (snapshot import with
a pinned anchor) and archive. Snap and fast verify the pivot state root and the epoch-switch anchor
before they execute.
Producer. XDPoS V2 block producer: votes, timeouts, QC and TC, sibling block on a head with no
QC, signer with a safety record.
RPC. Eth, net, web3 and XDPoS namespaces. Follower nodes answer a typed error below their
retained window.

Build xOne/v0.1.0-85a75a23-12112026. Details: docs/ops/net2040-sync-modes.md, section "Resync
2026-11-12, third run", and issue #47.

Every node type (snap, fast, minimal, archive, full) synced to the tip and equal to the archive
node on blocks, receipts, balances, code, storage and masternodes inside its window.
Each of snap, fast and minimal sealed 3 of 3 eligible turns on a borrowed seat, each block equal on
the archive node:

Node Seat Seals

snap 0xc33a 780010, 780023, 780036

fast 0x00ce 780063, 780076, 780089

minimal 0x00ce 780114, 780127, 780140
The full node held seat 0xa0ea for the whole day with 0 missed turns.

Three seals per node are a smoke test, not reliability evidence.

#118 signer: the ADR-010 quiet window is 0 on every chain except 50 and 51, so the fence is
inactive on net2040 and private chains.
#119 net: a snap-synced node reports total difficulty counted from its pivot in Status, so peers
rank it last.
#120 conformance: EVM oracle gaps (weak difficulty-56.4M vector, BALANCE mask undetectable, missing
Amsterdam, TRC21-token, BLS-P256 and EIP-7702 vectors).
#121 rpc: the typed unsupported-history refusal reports the head as pivot on snap, fast and
minimal nodes.
#122 rpc: eth_subscribe newHeads and logs return an id but deliver no notification.
#123 ethstats: a node started with --minimal reports syncMode "full".
#128 producer: no sibling when the head's round is at or above ours; the taken-off block's
transactions are not re-injected (Gate D case A1).
