Ethereum’s Proof of Stake demystified

If you have been on the hype-train of blockchains and following the news, you must already have heard that Ethereum network is planning to switch from its Proof of Work (PoW), to a Proof of Stake (PoS) consensus algorithm. This change has been debated for a while, and it is considered to be a major change in the way the Ethereum network works.

PoS will enable the Ethereum network to overcome the limitations of the current PoW consensus that result to the scalability issues. Other benefits include:

  • No need to consume large quantities of electricity.
  • Because of the lack of high electricity consumption, there is not as much need to issue as many new coins in order to motivate participants.
  • Proof of stake opens the door to a wider array of techniques that use game-theoretic mechanism design in order to better discourage centralized cartels.
  • Reduced centralization risks.
  • Ability to use economic penalties to make various forms of 51% attacks vastly more expensive.

Proof of Stake FAQ

As all changes to the consensus algorithm, this switch will result another fork (after the DAO insident…) of theĀ  network.

The change to PoS has caused a lot of speculation over the time. Now, the Ethereum guys have published a FAQ on the project’s wiki page on github, which might shed some light.
