The formulas used to calculate them may differ slightly

PoW (Proof-of-work) – a participant is granted the right to certify a block after completing work of sufficient complexity, the result of which meets pre-established criteria.
PoS (Proof-of-stake) – a block can be verified by a network participant whose amount of funds and account ownership period meet the specified criteria.
PoS + PoW is a hybrid protocol in which block verification occurs both through morocco rcs data calculated PoS criteria and PoW enumeration. This option is used to complicate the recalculation of the chain from the first block, which is possible when using PoS in its pure form.

PBFT (Practical Byzantine Fault Tolerance), Paxos, RAFT – algorithms that establish network consensus in several stages. Thanks to them, the blockchain functions with low costs and significant throughput, but is poorly suited to the growth of the number of users.

Non-BFT (Non Byzantine Fault Tolerance) – algorithms that are poorly resistant to behavior in which some users work against the blockchain. This protocol can be used in closed networks with full identification.
