Decentralization & Scalability - Starknet's Grinta upgrade on Mainnet marks a major step towards decentralization by introducing 3 sequencers operating in rotation using Tendermint consensus [1][2] - The architecture is now prepared for progressive decentralization of sequencing, although currently operated by StarkWare [2] - Grinta introduces a mempool system, allowing apps to send multiple nonces in parallel, boosting scalability [2] User Experience & Transaction Processing - Pre-confirmations provide near-instant feedback (~0.5 seconds latency), giving users immediate confirmation of transactions [2] - Block time has been reduced by 7x, significantly improving Starknet's speed and responsiveness [5] Fee Structure & Transaction Standards - Starknet now employs a modern fee model inspired by EIP-1559, including base fees and tips across L1 gas, L2 gas, and L1 data gas [2] - Base fees adjust with congestion, with fees expected to remain below 3 gFRI per L2 gas, ensuring subcent usage for most transactions [2] - Only v3 transactions are supported, with STRK as the default gas token, while Paymasters (like AVNU) enable fee payments in other tokens [3] - SNIP-29 introduces a standardized Paymaster API, facilitating seamless integration for fee payments in tokens other than STRK [3] Transaction Management - Transactions are prioritized based on added tips and can be replaced if conditions change [4] - Old or stale transactions are automatically cleared, preventing fragmentation [4]
