Dero

Its implementation builds out a main chain from the DAG network of blocks, which refers to main blocks and side blocks. Side blocks contribute to chain proof-of-work security, making traditional 51% attacks impossible. In contrast to traditional blockchains, Dero considers the transaction as the smallest unit of computation, not the block. Therefore, blocks on Dero can contain duplicate or double-spend transactions, but these are filtered by the client protocol and ignored by the network.

Dero aims to manage combining the security and decentralization of a proof-of-work blockchain with the scalability and transaction speed of DAG technology. Dero’s goal is a blockchain network that can serve businesses and individuals worldwide and support secure, fast, and anonymous transactions and smart contract execution.
