Technology is gaining traction and changing the way we do things. You can consider cryptocurrency like Ethereum to be the digital upgrade to fiat currencies like dollars and pounds. Companies like BTC Trading Inc review Ethereum ETH Proof of Stake, one of Ethereum’s latest updates before Ethereum 2.0 or ETH 2.0. 

Read on to know more about it.

What is Proof of Stake?

Before talking about Proof of Stake, you should know how cryptocurrency works. Blockchain technology operates most, if not all, of the cryptocurrencies available. A blockchain is a list of records that’s resistant to data modification. They link it together using cryptography, which contains a timestamp, transaction data, and a cryptographic hash of previous blocks.

Proof of Stake or PoS refers to represented consensus algorithms used for public blockchains. The consensus algorithm means that the creating of new blocks should be agreed on by all current validators. Check out this BTC Trading Inc Review to learn more what experts say about the Ethereum ETH Proof of Stake.

How Proof of Stake Works

Before discussing how PoS works, you need to know about its predecessor, the PoW, or Proof of Work. The PoW is generally a mechanism for consensus, preventing service abuse like spam and denial of service or DoS attacks.

While the algorithm of Proof of Work or PoW blockchains rewards participants for solving cryptographic puzzles for mining and validating transactions, Proof of Stake or PoS public blockchains are different. In POS-based blockchains, validators take turns in proposing and voting on the succeeding block. The weight of the vote of the validator highly relies on the stake or deposit. 

Here are some of the benefits of Proof of Service:

  • Greater security
  • Energy efficiency
  • Reduced risk of centralization

Types of PoS

Proof of Stake involves assigning rewards to all validators who participated in different consensus algorithms. The two kinds of PoS include BFT-style PoS and chain-based PoS.


Here are the differences between the two:

  • BFT-style PoS: All validators have varying rights when proposing blocks. When voting for a specific block, all online and honest validators permanently decide whether a block is truly a part of a chain. The new block may come in a single block without depending on the size or length of the string.
  • Chain-based PoS: The newly created block should depend on the previous block, usually the intersection of the longest chain, converging into one constantly growing chain.


Now with Ethereums’s PoS, here are the minimum requirements:

  • At least 32 ETH per validator
  • Internet connection
  • Computer with sufficient hardware specs
  • Software: Beacon nodes (a hub for validators) and validator clients (talks to sign blocks and beacon node).


There’s no need to consume too much electricity when securing a blockchain with Proof of Stake. It opens more opportunities to discover more techniques that you can use in game-theoretic mechanism design. Of course, it will give you higher returns without disproportionate gains. Staking on Ethereum would require special software aside from stake requirement, computer, and internet connection.
