Somnia Mainnet Releases
somnia-c2ebe4eae665079-release - Jig Hard Fork
Activated: 6th August 2026, 11:00 UTC
The Jig hard fork is a network upgrade that introduces:
Sustained gas discounts: rewards sustained usage with a discounted base gas price. See Sustained Use Gas Discounts.
Blake2f fix: corrects an edge case in the Blake2f precompile
GASPRICEsemantics: theGASPRICEopcode (tx.gasprice) now returns the price actually charged for the transaction - the sender's discounted base price plus their priority fee - rather than the block's base gas price. This applies to all transactions, calls and simulations, and makesGASPRICEsender-dependent. Contracts that usetx.gaspricefor gas reimbursement or fee floors should review that logic.Block history: gas limits reported for historical blocks are now capped consistently
This release also improves RPC compatibility, consensus performance and stability:
#1762 Implement eth_sendRawTransactionSync
#1751 Add accessList field in RPC responses
#1734 Add
removedfield to eth_getLogs log objects#1765 Harden RPC storage key-type validation
#1742 Aggregate BLS public keys for message verification
#1743 #1744 Parallelise and cache the PBFT leader's BLS verifications
#1737 Parallelise backend validation by transaction
#1749 Replace validator shards with a single MPMC queue
#1724 Reduce storage database stalls when pruning
#1730 Retire obsolete storage data types
Reclaiming disk space:
After upgrading, node operators can reclaim significant disk space (hundreds of gigabytes on long-running nodes) by deleting the storage data types retired in #1730. With the node stopped, run:
