celestiaorg/celestia-app v10.0.0-corto

on GitHub

Upgrade Notice

This release is intended for the Corto testnet (corto-1). If you are upgrading from v9 please read through the release notes.

v10 introduces fibre, a data availability protocol served by validator-operated fibre servers, together with the new x/fibre and x/valaddr modules. Validators are recommended to run a fibre server and register their host on-chain; see the fibre server guide. This release also bumps celestia-core to v0.41.0.

Supported operating systems

See the canonical matrix in the README.

• Tested in CI: Ubuntu 24.04 LTS (Noble Numbat) on x86_64
• Prebuilt binaries provided: Linux (amd64, arm64), macOS (amd64, arm64). arm64 binaries are cross-compiled and are not executed in CI.
• Minimum glibc: 2.38. Ubuntu 22.04 and older are not supported for multiplexer builds and will fail to start with a glibc version mismatch error.
• Changes since the previous release: none

What's Changed

Fibre

• The fibre and valaddr modules are enabled by default; build tags are removed (#7493). The fibre server ships as its own release archive per platform, versioned in lockstep with celestia-appd (#7577).
• The privval gRPC endpoint is enabled by default on every node and its default address moved to 127.0.0.1:26669; the fibre server uses it for payment-promise endorsements and its TLS identity (#7493, #7306).
• On-chain fibre params with governance bounds: payment_promise_timeout (10m-12h, default 1h), shard_retention (10m-168h, default 4h), full-stake storage budget default 2 TiB; per-validator storage budgets are derived from stake (#7582, #7689, #7607, #7634).

Consensus & state machine

• Transaction fees must be paid in utia only (#7734).
• Blob transactions must use canonical protobuf encoding (#7705).
• The per-block SDK message limit counts messages nested in authz MsgExec, ICA MsgRecvPacket, and MsgModuleQuerySafe (#7745, #7761, #7762).
• The evidence window (MaxAgeNumBlocks) is reduced to 404,400 to stay within the unbonding period; the v10 upgrade handler applies it (#7706).
• x/forwarding supports a custom IGP hook, now part of the forwarding address derivation (#7526, #7643); forwarding checks spendable balance (#7386).
• x/zkism supports SP1 v6 Groth16 proofs (#7374).

Node operators

• Heavy RPC endpoints are gated by a concurrency limit, configurable via max_concurrent_heavy_requests (default 20) — from celestia-core v0.41.0.
• Optional blockstore compaction: [storage] compact and compaction_interval in config.toml, plus a new celestia-appd compact-blockstore command (#7285).
• New --otel-endpoint flag pushes node metrics to an OpenTelemetry collector (#7200).
• Arabica is retired in favor of the internal Corto testnet (corto-1); the Mocha chain ID is now mocha-5 (#7605, #7709).
• download-genesis verifies the genesis SHA-256 before replacing the existing file (#7733).

Sync & stability

• PayForFibre signature verification no longer depends on a node-local cache, fixing a sync halt for replaying and state-syncing nodes (#7739).
• State sync snapshot restore crash fixed (#7737); NMT tree pool is self-healing (#7673).
• The multiplexer embeds v9.0.4; embedded v3-v8 run with the inter-block cache disabled (#7750) and embedded v4/v5 pin minimum-gas-prices (#7404), fixing genesis-sync issues.

Dependencies

• celestia-core v0.41.0, cosmos-sdk fork v0.52.11, go-square v4.0.0, nmt v0.24.4, rsmt2d v0.15.3, hyperlane-cosmos (celestiaorg fork) v1.3.0. Building from source requires Go 1.26.6.
