Pure Proof of Stake:
This is Algorand’s consensus protocol. The consensus protocol is how all the nodes on the network reach an agreement about what is stored in each block. Older blockchains use the proof of work model, and when you deal with the blockchain trilemma, it isn’t the fastest or most scalable. Transactions can take up to an hour, requiring several confirmations to be considered finalized. Algorand’s pure proof of stake model solves this issue. It is scalable, un-fork able, all while providing instant confirmations. By simply holding Algorand, you receive staking rewards. It is as simple as that.
Algorand is verified un-fork able:
Algorand will never fork. It can not happen. This means that transactions are final and can never be reversed. Only one block at a time can be confirmed, so the transactions are instantly final.
