PANews reported on August 26 that Ethereum research company Chainbound has completed a $4.6 million seed round of financing, led by Cyber ​​Fund, with participation from Maven 11, Robot Ventures and Bankless Ventures. Angel investors include Flashbot's Hasu, Titan Builder co-founder Kubi Mensah and Ethereum Foundation researcher Mike Neuder. Chainbound is developing a protocol called Bolt, which will enable "pre-confirmation" of Ethereum transactions, shortening the transaction confirmation time to less than one second, significantly improving the current average confirmation speed of seven seconds. Bolt is expected to be launched first on the Helder testnet and is scheduled to be launched on the Ethereum mainnet before the end of the year.
