In many cases, your chances of landing a new block (and the associated rewards) go up as you put more at stake.

Essentially, people who propose new blocks of information to be added to the record must put some cryptocurrency at stake. But they have a different way of incentivizing honest behavior among those who participate in that process. Proof of stake systems have some similarities to proof of work protocols, in that they rely on users to collect and submit new transactions. Some of the cryptocurrencies that use proof of stake include Cardano, Solana and Ethereum (which is in the process of converting from proof of work). It eschews mining in favor of a process known as staking, in which people put some of their own cryptocurrency holdings at stake to vouch for the accuracy of their work in validating new transactions. Proof of stake is another way of achieving consensus about the accuracy of the historical record of transactions on a blockchain. Ultimately, the goal of proof of work is to make it more rewarding to play by the rules than to try to break them. In this instance, spending the money on energy costs in an attempt to tamper with the historical record would have resulted in significant loss. If you win the right to create a block, it might not be worth the risk of tampering with the records and having your submission thrown out - forfeiting the reward. But the huge upfront cost is also a way to discourage dishonest players. The completion of this puzzle is the "work" in proof of work.įor lucky miners, the Bitcoin rewards are more than enough to offset the costs involved. To decide who gets the reward, Bitcoin requires users to solve a difficult puzzle, which uses a huge amount of energy and computing power. There is stiff competition for these rewards, so many users try to submit blocks, but only one can be selected for each new block of transactions.

Blockchains rely on users to collate and submit blocks of recent transactions for inclusion in the ledger, and Bitcoin's protocol rewards them for doing so successfully. Bitcoin uses proof of work, which makes this method an important part of the crypto conversation. Proof of work is one way of incentivizing users to help maintain an accurate historical record of who owns what on a blockchain network.
