What type of consensus algorithm does Radix use to validate transactions and secure its network?

Radix uses a novel consensus algorithm called Tempo to validate transactions and secure its network.

Tempo is a Byzantine Fault Tolerant (BFT) consensus algorithm that is designed to be fast, secure, and energy efficient. It works by having a set of validators that are randomly selected from the network to create blocks of transactions. These validators then use a distributed ledger technology called the Radix Distributed Ledger (RDL) to securely store and process transactions.

The RDL is designed to be highly scalable, allowing for thousands of transactions per second with minimal latency. The Tempo consensus algorithm works by having each validator in the network sign off on each transaction before it is added to the ledger. This ensures that all transactions are verified and agreed upon by all participants in the network before they are added to the ledger.

The consensus algorithm also ensures that no single validator can control or manipulate the ledger, as all validators must agree on each transaction before it is added. In addition, Tempo also uses a unique voting system called Proof-of-Stake (PoS) which allows users to stake their tokens in order to become validators on the network. This allows users who have staked their tokens to earn rewards for verifying transactions and securing the network.

Overall, Radix's Tempo consensus algorithm provides a secure and efficient way for users to validate transactions and secure its network while also providing an incentive for users who stake their tokens in order to become validators on the network.
