Jeff Garzik, one of a handful of key developers who helped build the underlying software for bitcoin that is known as blockchain, has seen its shortcomings firsthand. So he decided to create a better digital currency.

He’s calling it Metronome and says it will be the first that can jump between different blockchains. For example, coins that are used for applications on the Ethereum blockchain will be able to move to Ethereum Classic before jumping onto Qtum or Rootstock, which connects with the bitcoin blockchain, said Garzik.

The mobility means that if one blockchain dies out as the result of infighting among developers or slackened use, metronome owners can move their holdings elsewhere. That should help the coins retain value, and ensure their longevity, Garzik, co-founder of startup Bloq that created metronome, said in a phone interview.

That’s a concern for many digital currencies. Infighting among developers and various supporters, and the slow pace of enhancements on the bitcoin blockchain have helped to limit use. Both bitcoin and its main rival, ethereum, have split into several versions.
