A secured Web 3.0 platform designed for enterprise-grade decentralized applications. The Dune Network is a novel platform for distributed applications over a blockchain. Dune Network is not a hard-fork of the Tezos ledger. It started with its own genesis block on June 24, 2019, but uses an extended version of Tezos' open-source software as a basis to create a new platform with a focus on the easy development of distributed applications, thanks to multiple programming languages and communication technologies with other blockchains. Dune Network is, both, a public ledger that uses a working Liquid Delegated Proof-of-Stake (LDPOS) with its Dune (DUN) token, and a free software platform that can be used to instantiate private blockchains, with a focus on security, correctness and ergonomy.
