Mainstream adoption of blockchains has been limited because of scalability, privacy, and interoperability challenges. Coralex is the first multi-tier blockchain network designed to address these challenges. Core to our hypothesis is the idea that many blockchains will be created to solve unique business challenges within unique industries. As such, the Coralex network is designed to support custom blockchain architectures while providing a trustless mechanism for cross-chain interoperability. At the root of the Coralex network is the first dedicated, public, enterprise blockchain: Coralex-1.
