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.

What is (#PBFT) Proof of Byzantine Fault Tolerance ?
Proof of Byzantine Fault Tolerance (#PBFT) is a consensus algorithm used in distributed systems to achieve #consensus among a network of nodes even in the presence of faulty or malicious nodes. It is specifically designed to handle #Byzantine faults, which refer to arbitrary and #malicious behaviors exhibited by nodes in a distributed network.
In #PBFT, a network of nodes forms a consensus group, and each node takes turns acting as a #leader. The consensus process involves a series of rounds where the leader proposes a value or a set of #transactions, and other nodes in the network vote on the proposed value. #Nodes communicate with each other to reach a consensus on the agreed-upon value.
To achieve Byzantine fault tolerance, #PBFT requires a minimum number of correctly functioning #nodes in the network. As long as a two-thirds majority of the nodes are honest and follow the #protocol, PBFT guarantees that the network can agree on a consistent value, even if some nodes are faulty or malicious.
#PBFT is often used in permissioned blockchain networks, where the participants are known and trusted, and the network operates in a more controlled environment. It provides fast finality, low #latency, and high throughput compared to other consensus #algorithms like Proof of Work (PoW) or Proof of Stake (PoS). However, PBFT requires a higher degree of network communication and is less suitable for open and #decentralized networks.
So, now you're wondering, I've never see any coin using this, Which coin uses this Consensus?
β> This is only the Hot Coin in 2016 - 2017 Bull-Run, which is #NEO Coin.
