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.

Self-custody
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. By taking your crypto off of centralized exchanges and holding your own private keys, you reduce the risk of hacks, scams, and theft. And instead of trusting another entity to protect your assets, you get to act as your own "bank," where you are in complete control of your assets. Self-custody isn't for everyone, though, and it comes with some real limitations. Here's what you need to take into account when weighing in wether or not to self-custody your crypto.
