Node images are published to ghcr.io/decentral-america/node-scala with one tag per release (1.8.1, 1.8.0) and per network (testnet-latest, mainnet-latest). See Install with Docker and Upgrade.
Node v1.8.1 (2026-10-24)#
A maintenance release with no change to consensus, the REST API or Ride. The public Testnet runs it.
Dependencies. groth16 0.2.1.2 and curve25519 1.0.1, both sha256-pinned.
Licensing. A third-party notice for the GPL-3.0 dependency.
Blockchain Updates. The gRPC bind address of the Blockchain Updates extension is configurable.
README and comment fixes.

Node v1.8.0 (2026-10-19)#
The first release after v1.7.0: consensus and build hardening, plus the work merged since July. Every node on a chain must run it before the chain reaches its finality-hardening-height. On the public Testnet that was height 90,000, already passed.
Block reward. Feature 26, Adjusted Block Reward Distribution, is votable from this release (activated on the public Testnet). Continuation transaction and Lease expiration are renumbered to 27 and 28; see Features and Activation.
Finality. HotStuff can be made authoritative on a network that opts in (
dcc.hotstuff.authoritative; the public Testnet does). Equivocating HotStuff voters forfeit their generation deposit fromfunctionality.hot-stuff-equivocation-penalty-height. A lagging HotStuff replica re-anchors near the tip (dcc.hotstuff.max-target-lag-fraction).Finality hardening (consensus change, from
finality-hardening-height). HotStuff quorum weight comes from generating balance, and proven equivocators weigh 0. A voter can’t be both a valid endorser and a proven equivocator. Blocks signed with the legacy BLS domain separation tag are no longer accepted.HotStuff and P2P hardening (no consensus change). A proposal gets a vote only after the expected leader’s own signed vote for it, proposal views are bounded, and gossip is validated before it is relayed. Endorser indexes are validated when a block is decoded.
Generators. A generating node can commit itself to each generation period (
dcc.miner.self-commit-to-generation), and recovers from peer-reconnection stalls on its own (dcc.network.peer-stall-threshold). A failed initial snapshot is retried instead of forging without a state hash.Transaction pool. Transactions that depend on a prioritised parent are kept and re-broadcast across new blocks instead of being dropped, and network-received transactions rejected before their dependency arrived are retried.
REST API.
GET /addresses/seq/*andGET /utils/seed*now require the API key; see Authentication.Settings. On a chain with history, consensus heights are pinned by the genesis signature. An unknown consensus key stops the node from starting; unknown REST, HotStuff and miner keys log a warning.
Network defaults. The built-in Testnet profile now uses port 6868 and the public Testnet node as its peer, and the Mainnet profile no longer ships third-party seed addresses. The built-in
testnetchain type is still not the public Testnet chain.Security. Netty updated for CVE-2026-75595, plus ingress-robustness hardening.
Build. Native libraries come from Maven Central with pinned checksums. Each release image is smoke-tested and scanned before it is tagged, and carries a build-provenance attestation.
The v1.8.0 image reports its version as DecentralChain v1.8.0-dev-1a1221cdd8: it was built just before the tag, from a tree that differs only in a CI workflow. The binary is the released one.
Source: the v1.8.0 release.
Node v1.7.0 (2026-07-25)#
The first official GitHub release of node-scala (v1.6.3 and earlier were git tags only).
Consensus safety fix. The experimental HotStuff vote pool now checks quorum against every committee snapshot seen while a target’s votes accumulate, closing a gap when committee membership changes mid-round. It also evicts stale votes from removed generators, bounds vote-pool memory, and verifies a quorum certificate locally before broadcasting it. HotStuff remains disabled by default (
dcc.hotstuff.enabled = false); the public Testnet runs it enabled and authoritative. See Features and Activation.REST API.
GET /node/statusnow includesgenerationPeriodLength, a per-network constant that no endpoint exposed before.Testing. Expanded end-to-end testing: deterministic simulation, fault injection with network partitions, property-based fuzzing, and OpenAPI conformance checks in CI. No runtime behaviour change.

SDK Release of 2026-06-23 (Not on npm Yet)#
A monorepo release commit of 2026-06-23 versions every SDK package for the 2.0 modernization: the packages moved from packages/ts to packages/sdk, gained a groth16 v2 verifier and a blst 0.3.16 rebuild, and many took a major version. The release tags were pushed on 2026-10-19:

None of these versions is published to npm: the registry’s newest transactions is still 5.0.1. These docs keep pinning the published versions listed in the TypeScript SDK page, and will move to the new majors once they are on npm.
Ride REPL v1.6.2 (2026-06-06)#
@decentralchain/ride-repl 1.6.2 is published to npm (tag ride-v1.6.2). It fixes the build of the JavaScript Ride compiler it bundles. See Ride REPL.
DecentralScan v2.1.0 (2026-06-13)#
The explorer gained the Testnet faucet: the /faucet page and the POST /api/faucet endpoint, paid from a dedicated wallet. v1.3.2 (2026-06-15) fixed the peer list, so All Peers shows the connected nodes. See DecentralScan Guide.
