Starknet, a layer-2 blockchain, has rolled out a significant upgrade dubbed version 0.13.2, introducing parallel execution to its network functionality.
According to a press release shared with Cointelegraph, the update will allow Starknet to process multiple transactions simultaneously, which is noted to be the first of an L2 network on Ethereum mainnet.
In the press release, Eli Ben-Sasson, CEO of StarkWare and board member at the Starknet Foundation, explained that L2 blockchains are like âminimarkets with a single checkout.â
âWeâre becoming the first âmegastore L2â â overhauling our sequencer so that numerous checkout lanes simultaneously handle countless transactions.â
Parallel execution implications
Parallel execution addresses the limitations of sequential transaction processing, traditionally seen on L2 networks, which lead to bottlenecks appearing during high demand.
According to the press release, Starknetâs parallel execution, part of the 0.13.2 upgrade, has been on testnet since Aug. 7 and will go live on Aug. 28.
Ben-Sasson states that the new feature is âa common-sense change,â which he expects will be followed by other networks and become âan industry norm.â
â...our challenge as an industry is to build infrastructure thatâs ready for anything. It needs to always be many steps ahead of demand, which is why parallel execution is going live now.âÂ
Block packingÂ
Alongside the introduction of parallel execution, the upgrade will also include a new feature known as âblock packing,â which aims to reduce confirmation times.
According to the press release, the new feature âpacks blocks with transactions more efficientlyâ to reduce costs and improve transaction speed by filling blocks with transactions without âempty space.â
Block packing will result in Starknetâs current confirmation time falling from its current range of 10-80 seconds down to two seconds and improve as more users join the network.
âThe beauty of L2 scaling is that it has the potential to drive costs down instead of up as more users join a network, and block packing is a prime example of this.â

Starknet-based protocol shutters
This latest Starknet upgrade follows the closure of ZKX Protocol, a social derivatives trading platform built on Starknet, due to the platform having no âeconomically viable pathâ forward.
On July 30, Eduard Jubany Tur, founder of ZKX, explained that user engagement had been âminimal, with only a few individualsâ mining native token rewards.
Tur explained that ZKX had delisted from all markets, closed its positions, and returned all funds to each userâs trading account.
