What was the problem?

This PR resolves PLAT-956.

Upstream cut op-node/v1.20.0 and op-reth/v2.8.0 from one commit (d662020). op-reth v2.8.0 is recommended for all operators: it moves the reth base from v2.5.2 to v2.6.0, warns on Storage v1 datadirs ahead of the January 2027 removal, and aligns derived-block and header validation with op-geth and the fault proof. op-node v1.20.0 is optional for Lisk; it removes the deprecated Req/Resp P2P sync server and its three metrics. Both keep the v1.19.11 / v2.6.1 security fixes.

No env, peer, entrypoint or flag change is needed: this image passes none of the flags removed or re-defaulted upstream.

How was it solved?

• reth/Dockerfile: op-node pinned to v1.20.0 and op-reth to op-reth/v2.8.0, both at commit d662020. Go 1.26.10, Rust 1.95, just 1.46.0 and Ubuntu 26.04 are unchanged upstream, so no toolchain pin moves.
• README.md: client versions and the op-reth source-tree link.

How was it tested?

I built the image natively on arm64 with PROFILE=release and FEATURES=jemalloc. CI covers the maxperf build on both linux/amd64 and linux/arm64.

Evidence (8 checks)

Check	Result
Upstream tags, peeled	op-node/v1.20.0 → d662020, op-reth/v2.8.0 → d662020: one commit for both
Toolchains at d662020	go.mod toolchain go1.26.10, rust/rust-toolchain.toml 1.95, mise.toml just 1.46.0; all match the Dockerfile pins
reth base	rust/Cargo.toml: ethereum-optimism/reth rev 0fbe428 (v2.5.2) → tag op-v2.6.0-1 (v2.6.0)
superchain-registry	08d6a44 → 13907b9, 24 commits (GIWA Sepolia, sepolia-devnet-3, other chains' roles and addresses). superchain/configs/mainnet/lisk.toml blob 1625e36 unchanged
Build recipes	op-node/Makefile and the build-superchain-go / update-superchain-registry-submodule just recipes are byte-identical to the previous pins. rust/op-reth/bin/Cargo.toml still defines jemalloc and asm-keccak; rust/Cargo.toml still has profile.maxperf
Flags changed upstream	reth-entrypoint, op-node-entrypoint and .env.mainnet pass none of: the BAL flags, --proofs-history*, --txpool.minimum-priority-fee, --rollup.historicalrpc, --engine.persistence-threshold, --db.rocksdb-block-cache-size, --p2p.sync.req-resp
op-node binary	v1.20.0-d6620202, go1.26.10, CGO_ENABLED=0, vcs.revision=d662020
op-reth on Ubuntu 26.04.1	glibc 2.43; ldd resolves all libraries; dump-genesis --chain lisk returns chain ID 1135. --version reports 0.0.0-dev, as on v2.6.1

Release draft v0.4.33 is prepared against main and will be published after this merges.

Full details: Description check

Explanation

The description follows the template's three sections (What was the problem?, How was it solved?, How was it tested?) and explains the motivation, the version pins, and the testing evidence. The problem section links the Linear issue PLAT-956 and states the upstream release facts, which replaces the template's #INSERT_ISSUE_NUMBER placeholder. The solution section lists the Dockerfile and README changes, and the testing section gives a native arm64 build, a table of eight checks, and the CI coverage. The one gap is that the description states testing results that the PR objectives describe differently: the description reports a full op-reth build and a runtime check, while the objectives say op-reth was still compiling when reported. That conflict affects how far the test claims can be trusted, but the required sections are present and substantive.

50-51: Trivial · Performance & Scalability

Check the memory budget for the new persistence default.

op-reth v2.8.0 changes --engine.persistence-threshold from 7 to 50. Upstream states that this retains more blocks in memory and increases memory use. This image does not set the option, while the README documents a 16 GB Docker limit and a 32 GB maxperf requirement. Measure memory use for a Lisk node. If it exceeds those limits, set a supported threshold or update the documented requirements.

@coderabbitai Not changing the persistence threshold or the documented memory requirements. Lisk Mainnet blocks carry about one transaction and under 60k gas each, so the 43 extra blocks held in memory add negligible state next to the 16 GB and 32 GB figures. Operators who want the old behaviour can set RETH_ENGINE_PERSISTENCE_THRESHOLD=7, which the release notes say. Evidence below.
