A node network that unifies different blockchains into a single API to create high performance decentralized apps without any drawbacks.
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.
Phantasma is a new platform defining both a storage specification and a protocol for sending messages from one source to one or multiple destinations via smart contracts. Phantasma running on top of the NEO blockchain then will be using NEOX cross-chain protocol to proceed fork into its own blockchain.
