from that height every block must carry an Ed25519 block permit signed by a compiled-in authorization key, and v1.13.20 or older nodes fall onto a legacy fork. https://argusnodes.com/chains/aleo 2026-08-19:change:Aleo Wed, 19 Aug 2026 09:00:00 GMT Network change snarkOS v4.9.1 (August 19, 2026) is a mandatory upgrade with mainnet consensus activation at height 21,342,000 (predicted August 24, 2026);

v1.30.0 deprecates and deactivates the quarantine module, so node operators should expect roughly bi-monthly coordinated upgrades. https://argusnodes.com/chains/arc 2026-06-04:change:Arc Thu, 04 Jun 2026 09:00:00 GMT Network change arc-node v0.7.2 (4 June 2026) lowered the default JSON-RPC gas cap to 30M, capped batch requests at 100 entries and rejects replay-unprotected (pre-EIP-155) transactions over RPC by default. https://argusnodes.com/chains/sora 2026-06-04:change:Sora Thu, 04 Jun 2026 09:00:00 GMT Network change The Substrate-based SORA network is still being released: sora2-network 4.8.8 (framenode) shipped on 4 June 2026 together with runtime upgrades 4.8.6 to 4.8.8. https://argusnodes.com/chains/vara 2026-06-02:change:Vara Network Tue, 02 Jun 2026 09:00:00 GMT Network change gear v2.0.0 (2026-06-02) is a mandatory node binary upgrade (runtime spec 20000): the WASM sandbox moved from Wasmer to Wasmtime, gclient was merged into gsdk, and the repository was reorganized to separate Vara from the new Vara.ETH execution environment. https://argusnodes.com/chains/near 2026-06-01:change:NEAR Mon, 01 Jun 2026 09:00:00 GMT Network change nearcore 2.11.0 carried protocol version 83 (vote 13 Apr 2026) and a further upgrade to protocol 84 was scheduled for 1 June 2026;

since then only opt-in Cuttlefish patch releases have shipped, most recently v1.3.0.4 (April 2026) and v1.3.0.5 (1 June 2026) adding the db.keep_previous_substate_values disk-space option. https://argusnodes.com/chains/bsquared 2026-05-31:change:B² Network Sun, 31 May 2026 09:00:00 GMT Network change The official node guides still pin op-geth v1.101315.2 / op-node v1.7.7 (snapshot 20250707) and the public RPC reported Geth/v1.101315.2 on 22 Aug 2026; OP Labs declared op-geth end-of-support on 2026-05-31, so B² nodes depend on a frozen client line with no published op-reth path. https://argusnodes.com/chains/blast 2026-05-31:change:Blast Sun, 31 May 2026 09:00:00 GMT Network change Blast's node stack (blast-geth) is a fork of op-geth; Optimism's upstream op-geth reached end of support on 31 May 2026, and Blast has published no migration path to reth. https://argusnodes.com/chains/bob 2026-05-31:change:BOB Sun, 31 May 2026 09:00:00 GMT Network change OP Labs marks op-geth as end-of-support on 31 May 2026 and names op-reth the primary supported execution client for OP Stack nodes, so any remaining op-geth BOB nodes should be migrated. https://argusnodes.com/chains/boba 2026-05-31:change:Boba Sun, 31 May 2026 09:00:00 GMT Network change op-geth and op-erigon reached end-of-life on 31 May 2026; op-reth is the only supported execution client and a migration guide generates a reth database from existing data. https://argusnodes.com/chains/gatelayer 2026-05-31:change:GateLayer Sun, 31 May 2026 09:00:00 GMT Network change OP Labs declared op-geth end-of-support on 2026-05-31 and it does not support the Karst hardfork; GateLayer's published docker-compose still pulls ghcr.io/gatechain/geth, so confirm the supported execution image with Gate before deploying. https://argusnodes.com/chains/ink 2026-05-31:change:Ink Sun, 31 May 2026 09:00:00 GMT Network change op-geth support ended May 31, 2026; Optimism says all node operators should migrate to op-reth (v2.2.3 or later), and op-geth cannot follow the now-active Karst hard fork. https://argusnodes.com/chains/katana 2026-05-31:change:Katana Sun, 31 May 2026 09:00:00 GMT Network change op-geth reached end-of-support on 31 May 2026 and does not support the now-active Karst hardfork; Katana's official node configs mark op-geth deprecated and tell all operators to run op-reth (v2.2.3 or later per OP docs). https://argusnodes.com/chains/mode 2026-05-31:change:Mode Sun, 31 May 2026 09:00:00 GMT Network change Optimism ended support for op-geth on 31 May 2026; op-geth does not support the Karst hardfork, so OP Stack node operators are told to migrate to op-reth v2.2.3 or later while op-node continues. https://argusnodes.com/chains/optimism 2026-05-31:change:Optimism Sun, 31 May 2026 09:00:00 GMT Network change op-geth reached end-of-support on 2026-05-31 and does not support the Karst hardfork, so op-geth nodes can no longer follow the canonical chain; operators must run op-reth (or Nethermind). https://argusnodes.com/chains/soneium 2026-05-31:change:Soneium Sun, 31 May 2026 09:00:00 GMT Network change OP Labs lists op-geth as end-of-support on 31 May 2026 and op-reth as the primary supported execution client, while Soneium's FAQ still documents op-geth; node operators should plan for op-reth. https://argusnodes.com/chains/astar 2026-05-28:change:Astar Thu, 28 May 2026 09:00:00 GMT Network change Client v5.49.2 (28 May 2026) was a CRITICAL upgrade migrating collators to slot-based Aura consensus, required by runtime-2207 (10 Jun 2026), which also froze WASM contract uploads and instantiation. https://argusnodes.com/chains/moonriver 2026-05-28:change:Moonriver Thu, 28 May 2026 09:00:00 GMT Network change Client v0.52.0 (28 May 2026) made slot-based authoring mandatory with a dynamic relay-parent offset; blocks authored with the wrong offset are rejected by the runtime, so collators and RPC nodes should run v0.52.x (latest v0.52.3, 15 Jun 2026). https://argusnodes.com/chains/fetch-ai 2026-05-27:change:Fetch.ai Wed, 27 May 2026 09:00:00 GMT Network change Actively maintained as of Aug 2026 (fetchd repo pushed 27 May 2026, mainnet reports fetchd v0.15.0 on CometBFT 0.38), but the docs active-networks page still lists v0.14.0 as the current mainnet version and the ledger is now documented under the ASI Network brand. https://argusnodes.com/chains/boba 2026-05-26:change:Boba Tue, 26 May 2026 09:00:00 GMT Network change The latest official mainnet archive snapshot (Reth, 26 May 2026) is 13.9 GB;
