Reading the participants&#x27; comments below the announcement, most of them speak of an open&#x2F;distributed ledger, not Bitcoin&#x27;s blockchain.
So it seems they really are <i>ditching</i> the original blockchain.<p><i>IBM intends to contribute tens of thousands of lines of its existing codebase and its corresponding intellectual property to this open source community. Digital Asset is contributing the Hyperledger mark, which will be used as the project name, as well as enterprise grade code and developer resources. R3 is contributing a new financial transaction architectural framework designed to specifically meet the requirements of its global bank members and other financial institutions. These technical contributions, among others from a variety of companies, will be reviewed in detail in the weeks ahead by the formation and Technical Steering Committees. </i>
