As the world speaks about the blockchain and distributed ledger technologies a brand new field is being appeared that solves value transfer with a P2P network but either totally without a global ledger or involves a global ledger only as a part of the algorithm. Some of these technologies are called as Layer 2 solutions, but probably better to name them as non custodian payment and state networks and include the following platforms:
- Lightning network
- Raiden
- microRaiden
- Liquidity network
- Interledger Protocol
- Hyperledger Quilt
- Actually the R3 Corda platform has some similar possibilities as well
