DigitalNote is an open-source blockchain relying on the Proof-of-Work/Proof-of-Stake hybrid protocol. The cryptocurrency associated with the network is XDN. The XDN Masternode Network is built on top of this protocol. The main features of this platform are high-speed untraceable transactions and secure private peer-to-peer communication channels. In order to send an instant transaction, one needs to use the InstantTX function which executes the instant XDN-transactions immediately via the Masternode Network. The messaging service is censorship- and tracing-resistant. The messages get decrypted locally on the receiver's device and nowhere else. The security of the network is achieved via the VRX v3.0 technology that protects the platform from 51% attacks. The DigitalNote wallet is mobile-ready and doesn't consume much resources so it's comfortable for people making transactions on the go.
Truebit is a blockchain enhancement which enables smart contracts to securely perform complex computations in standard programming languages at reduced gas costs.
