Attention all Taiko Alethia Node Runners! The Fusaka upgrade is rolling out to Ethereum on December 3, 2025, at 21:49:11 UTC. With this upgrade comes EIP-7594, which introduces data sampling instead of full downloads; this means that if you are not running an Ethereum semi-supernode or supernode beacon client, your L2 node will not function as intended. Please configure your beacon client with the respective flags (detailed below) before the Fusaka hard fork date to avoid interruptions. - Lighthouse: --semi-supernode or --supernode - Teku: --p2p-subscribe-all-custody-subnets-enabled - Grandine: --subscribe-all-data-column-subnets - Lodestar: --supernode - Nimbus: --debug-peerdas-supernode Alternatively, you may set a --blob.server url if you wish to use a a thirdparty or self hosted blob indexer service. This can be done with BLOB_SERVER_URL in simple-taiko-node's .env. We’ve also released some mandatory upgrades to taiko-client and taiko-geth. If you are running an L2 node, please upgrade to the following versions as soon as possible: Software Versions: - taiko-alethia-client v1.11.0 - taiko-geth v1.17.3 - simple-taiko-node v1.22.0
