Summary of differences between PoW and PoS

Home Cursos y webinars Cryptoassets / Blockchain Validation in the blockchain Summary of differences between PoW and PoS

Characteristic	PoW	pos
Consensus	Based on computing capacity	Based on the participation of nodes holding a certain amount of native crypto assets.
Reward	Miners receive new crypto assets and transaction fees.	Validator nodes receive new crypto assets and transaction fees.
Use of energy	It requires a lot of electricity and water consumption to achieve the comutational power of miners.	It requires little electrical power since the nodes do not require high computational capacity to validate transactions.
Security	High, due to the cost required to carry out a 51% attack.	It depends on the validation model and the level of centralisation of the validator nodes.
Scalability	Low, due to the limitation of block size and the average time it takes for new blocks to. be added to blockchain.	Greater because blocks can be incorporated more quickly.
