# BIS ?

Unified legder

"BIS said that “a unified ledger does not imply a sole ledger that overshadows all other systems in the economy”. Instead, it might involve a “central bank-operated core infrastructure and satellite interconnected systems operated by other entities.”

It will restrict initial participants to commercial banks, but it may later expand access to other payment providers, depending on regulatory approval.
