Crypto staking is a method of achieving network consensus and maintaining the security of a blockchain network by incentivizing users to hold and validate transactions on the network. It is sustainable because it provides a source of income for those who participate in the validation process, which encourages more people to join the network and support it. Additionally, staking helps to decentralize the network, as it allows for more participants to validate transactions and participate in decision-making processes, making the network more resilient to attacks and less reliant on a small number of validation nodes. Furthermore, many proof-of-stake networks have implemented economic mechanisms such as token burns or buybacks, which can help maintain the long-term value of the network’s native token, further incentivizing users to continue staking and supporting the network
