What is the Solana consensus protocol?

Not only Solana AKA «the ethereum killers», but most of the new Blockchain, are based on the PoS consensus platform . Which is basically a replacement for PoW miners in order to validate the next block.

Contrary to what conventional blockchain mining does, Solana not only uses the Pos protocol, but adds a second consensus process called PoH (Proof of history), which acts as a seal and adds a cryptographically verifiable date, which speeds up the verification process, and leaves validating nodes out.

This is how Solana reaches an operating speed of 400 milliseconds.

One of the milestones of Solana, over Bitcoin and Ethereum and that is due to the consensus protocols that it integrates, is scalability.

While the structure of Ethereum from its conception was designed prioritizing decentralization and security, Solana is designed to integrate these three characteristics in an agile way.

The ethereum and bitcoin consensus process, have as a characteristic and main disadvantage compared to solana that they are visibly slower and tend to saturation.

Although Ethereum has on several occasions integrated soft forking fixes in order to resolve saturation issues, the average transaction cost of between 3 and 6 dollars (reaching 70 dlls in 2021) is reason enough for his death to be an announced chronicle.

Of course, Ethereum tends to evolve from PoW to PoS protocol, eventually promising speeds of up to 100,000 TPS. But this integration will last at least a year to be true and we do not know if by that time what the real state of ETH will be, for which things undoubtedly look difficult.

Meanwhile, Solana currently has more than 400 decentralized projects that can boast a good level of success. The eclipse over ethereum seems to be imminent, Solana only has to prove that it is an efficient and sufficiently secure payment network.
