OneLedger is a cross-ledger agnostic protocol that enables high-performance scaling using a sharded and modified practical Byzantine Fault Tolerant consensus scheme -- which allows for either a permissionless or permissioned setting. By coupling public key infrastructure (PKI) with identity management, nodes (and node operators) will have a defined trust hierarchy that allows them to participate in the consensus of the OneLedger chain or any sidechain.
OneLedger sidechains can be synchronized with the current state of other networks (Ethereum, Bitcoin, etc.). Any cryptocurrency that supports hashed time lock contracts (HTLC) and payment channels could be deposited into an account or address with the amount credited onto the OneLedger sidechain. This allows for a scalable and transparent solution that is off the main network or chain and is now off-loaded to the OneLedger sidechain. An arbitrary number of transactions between users can occur on a OneLedger sidechain prior to the final user requesting a withdrawal of their balance from the hashed time lock address / account on the main chain to the address / account of their choice. Essentially, OneLedger provides a scalable `off-chain` solution from any main chain and offloads the consensus to the corresponding OneLedger sidechain which inherits all of the properties of the OneLedger protocol.
