Proof-of-stake might be profitable for everyone, but governance comes down to a few holders.Whales aren’t necessarily the problem. Interest rewards increase the gap between stakeholders, even if that gap was just $100. Proof-of-stake needs smart contracts that prevent early holders from taking up the network.Proof-of-work is based on computing power. “Mining” is a competition between powerful devices to solve cryptographic puzzles to win block rewards. The network security increases proportionally to the energy spent.Thus, the most competitive miners have dozens of devices and live in countries with low electricity costs. These tend to centralize by creating mining pools. All miners from a pool contribute computing power and get proportional rewards for their contribution.

If users need high-tech devices, technical knowledge, or thousands of dollars, fewer will become validators. In order to attract validators in the first place, the consensus model should be rewarding enough for the whole.To become an Ethereum validator, for example, you need to stake over 32 Ethereum, have enough hardware storage, and keep your device always online.

So it’s recommended to update smart contract penalties as well.<h5>Develop the Ecosystem</h5>As more people use the network, scalability issues arise. When a blockchain doesn’t scale well, users cause network congestion and expensive fees. This drives away new users and incentivizes people to hold rather than use those tokens.But utility tokens aren’t a store of value. When treated that way, proof-of-stake tends to centralize.
