In September, Starknet will activate Grinta (v0.14.0), its most ambitious upgrade to date. The release introduces multi-sequencer architecture, sub-second pre-confirmations, faster blocks, and a new fee market, pushing the Ethereum Layer-2 closer to full decentralization.
According to Starknet team, Grinta isnât just an upgrade. Itâs a turning point in L2 design, bringing Starknetâs infrastructure in line with its decentralization and UX goals, while giving builders a faster, fairer, and more programmable network.
Hereâs what v0.14.0 brings to mainnet:
Starknet now runs with three sequencers (StarkWare + partners like Juno), moving away from a centralized operator. It uses Tendermint BFT to agree on blocks, with a roadmap to expand to a permissionless set.
Block finality now depends on Top 100 STRK stakers, requiring â weighted signatures: a governance-linked security layer.
For fallback, a temporary âsafety leverâ lets StarkWare step in if liveness drops too low, overseen by a Security Council.
Starknet introduces pre-confirmations in ~0.5 seconds, decoupling user experience from full finality. Transactions now feel instant, while full consensus continues in the backgroundâhuge for DeFi and gaming.
From 30s down to 4â6s, block times get a dramatic boost. Further reductions are planned, including native Cairo execution to scale throughput without sacrificing STARK-proof security.
Starknet ditches FIFO mempools and introduces:
The base fee isnât burned yet, but thatâs coming later this year. For now, the model aims for predictable costs, spam resistance, and validator sustainability (~$1K/month run cost).
Validators and full node operators must upgrade clients immediately (e.g., Pathfinder v0.10.3+, Juno v0.9.1+).
Grinta isnât just about Ethereum. It aligns with Starknetâs broader roadmap, including:
Starknetâs Grinta upgrade delivers on three fronts: decentralization, usability, and economic design. Itâs the first step toward full permissionlessnessâand a clear signal that the L2 race isnât just about TPS anymore.
Real voices. Real reactions.
@Starknet STARKTEMBER!!!! MAKE STARKNET GREAT AGAINđ
I am back. grinta mode is on. Get ready for Starktember and BTCfi on Starknet. And Starknet is still the ultimate scaling engine, secured by the most battle tested and efficient ZK proving infra in the world btw. Probably can be useful for hyperbitcoinization going forward.
@Starknet Grinta mode on Starknet is almost here.. i cant wait for this upgrade that opens a new chapter for Starknet. See you all in Stark_ember.
