What is #PoET (Proof of Elapsed Time) ?
Proof of Elapsed Time (#PoET) is a consensus mechanism that is used in some blockchain networks to validate transactions and create new blocks. It is based on the principle of #randomly selecting a validator node to create a new block, but unlike Proof of Work (#PoW), PoET does not require energy-intensive computations.
In #PoET, nodes in the network wait for a randomly generated timer to expire before attempting to create a new #block. The timer is set by a trusted execution environment (#TEE) which is a secure, isolated environment within a node's hardware. When a #node's timer expires, it is allowed to create a new block and broadcast it to the network. The node that creates the next valid #block is rewarded with cryptocurrency.
The idea behind #PoET is that the randomness of the timer selection ensures that no single node has an #advantage over others in the network. The use of TEEs also makes the process more secure, as the timer cannot be manipulated by #malicious nodes.
#PoET is used in some blockchain networks, such as #Hyperledger Sawtooth, to achieve consensus in a more #energy-efficient and secure manner compared to #PoW.
