PANews reported on November 13 that according to Cointelegraph, Ethereum researcher and co-founder of Smart Transactions (STXN) Vlad Zamfir has created a "time machine" that allows Ethereum users to reverse "smart transactions" on the blockchain, making some transactions no longer so tamper-proof. Anuj Das Gupta, co-founder of STXN, said Smart Transactions also allow users to set specific conditions for the timing and execution of transactions. This feature will be supported on blockchains compatible with the Ethereum Virtual Machine (EVM), which will be very useful for the thousands of crypto users who have traded on the chain due to misoperation. "Ethereum smart contracts are no longer limited to what was known at the time of writing," said Das Gupta. "We believe this is an important solution to the tension between flexibility and immutability in blockchains."
