The new public chain Linera has released a white paper, introducing the idea of parallel operation of multiple chains within the same group of validators

ChainCatcher news, the new public chain Linera, founded by former Libra employees, has released its white paper today. The white paper introduces the idea of "microchains," which allows for the parallel operation of many chains (potentially millions) within the same group of validators. In Linera, scalability is achieved by adding chains rather than increasing the size or rate of blocks. Linera encourages users to operate their own microchains. When a microchain is operated by a single user, Linera employs a simplified memoryless pool consensus protocol inspired by reliable broadcasting.

Linera's founder and CEO, Mathieu Baudet, is a former Meta employee who helped create the Libra blockchain. Linera completed a $6 million seed round funding led by a16z at the end of June this year. (source link)
