Odaily News Vlad Zamfir, an Ethereum researcher and co-founder of Smart Transactions (STXN), has created a "time machine" that allows Ethereum users to reverse "Smart Transactions" on the blockchain. STXN co-founder Anuj Das Gupta said at the DevCon conference in Bangkok that the smart transaction also allows users to set transaction times and specific conditions for execution. "STXN is like a time machine because it allows us to ensure the future of smart contracts," Das Gupta said in a statement. The feature will be supported on EVM-compatible blockchains. Das Gupta said: "Ethereum smart contracts are no longer limited by what is known at the time of writing. We believe this is an important solution to the tension between the flexibility and immutability of blockchains." (Cointelegraph)
