PoS cryptocurrencies
First, I would like to point out that not all PoS blockchains support a high level of decentralization: some of them allow developers and the largest whales (which are basically the same group of people) to establish an oligopoly in validation. Less decentralized versions of PoS are used in EOS or Tron , and proof of stake authority is used in Binance Smart Chain .
used by Cardano and Polkadot. The idea is to join a pool of kazakhstan number data participants, where even a small coin holder can indirectly participate in the consensus and receive some percentage of the transaction fees.
The most notable upgrade so far is Pure PoS, used in the Algorand blockchain. This improvement allows almost anyone to become a validator of the network and operate with minimal computational and investment contributions, starting from one dollar. In Algorand, finalization is extremely fast and the level of decentralization is high, since the choice of validator is random and cryptographically protected.
It is worth remembering that Ethereum is moving towards the PoS method, being the second largest cryptocurrency by capitalization! As soon as the work on Ethereum 2.0 is completed, it will begin to fully utilize the advantages of PoS, such as high scalability and transaction throughput, while maintaining the signature high level of security and decentralization. There is reason to believe that the list of PoS "coins" will expand.
