The technology, Time Ordered Merkle Epoch (TOME), aims to incorporate traditional trading systems into blockchains by recording trading data in a time-series and creating a hash that can then be “anchored” to public blockchains, combining both off-chain order information and on-chain settlement information. This marks the latest move in tZero’s digital securities strategy, including another patent earlier this year aimed at integrating traditional trading systems with cryptocurrency exchanges, several high-profile hires, and the issuance of Overstock dividends in the form of tokenized digital shares.
