Proof of Stake vs Proof of Work – What will this mean to Nvidia?

Next year Ethereum will moving to a new algorithmic operating model (Casper FFG or Ethereum 2.0). The major update will be a move from Proof of Work (PoW) to Proof of Stake (PoS). With PoW miners run complex GPUs tasks to mine validation blocks. The Casper algorithm removes mining and moves to verification and validation of new blocks of transactions by block validators, which will be selected according to their stake.

The voting power of each validator will be determined by the amount of ETH they put up for stake. For example, someone who has deposited 64 ETH will have double the voting weight of a validator which deposits the minimum.

The move towards Proof of Stake is seen as an advantage by may as it is more environmentally friendly, as well as being more secure. Any validators that act maliciously will be penalized and removed from the network.

It will be interesting to see how this effects Nvidia. It has been reported that cryptocurrency miners bought 3 million GPUs in 2017! That’s a lot of GPUs that won’t be needed anymore. As Nvidia is the major GPU producer in the world it will be interesting to see how this affects them.
