- faster TPS transactions
- lower transaction fees (compared to Ethereum and Bitcoin)
Cardano developed its own Proof-of-Stake algorithm Ouroboros. With Ouroboros, the transactions are validated via “Pools”. Pools are the servers that actually process transactions, and to do that they are using the wallets of ADA holders. ADA holders have to authorize Pool to sign transactions on their behalf.
Ouroboros rewards users who stake their ADA to validate transactions and help secure consensus.
The advantage of this mode of operation over the proof-of-work system is the mathematical certainty in choosing a blockchain validator, and the speed and lower power consumption.
