What is Delegated Proof of Stake (DPoS): a more democratized approach to Proof of Stake
One of the primary aspects of any blockchain is its consensus algorithm or consensus mechanism. This is simply a name for the system used to achieve agreement among participants regarding the network's state. As you know, in decentralized networks, there’s no central authority. As a result, any decision needs to be made by the community through a voting process. The cryptocurrency industry initially had the Proof of Work (PoW) algorithm, which launched with Bitcoin. Later, it developed a different approach called Proof of Stake (PoS). However, PoS also got modified in time.

What are the limits of self-custody?
Self-custody wallets have often been touted as a great way to keep your crypto safe, and for good reason.
