Enigma is a secure off-chain blockchain protocol that serves as a second layer to other blockchain networks. This protocol aims to create a network that will solve the two biggest issues plaguing most cryptocurrencies today: privacy and scalability. Enigma allows for decentralized data computation, exchange, and storage in contrast to the traditional centralized solutions that blockchains may be forced to use to not bog down transactions. Nodes of Enigma don’t see the data they are computing, allowing for secret smart contracts that maintain their integrity. Decentralized applications can be built on the Enigma protocol, the first being a data marketplace called Catalyst.
Enigma (ENG) Ethereum tokens are required to be deposited by full nodes, and these nodes are then compensated for their computational power through token fees.
