How does bitcoin replace trust with proof
Can Bitcoin do proof of stake?

Does Bitcoin rely on proof of work?
Does Bitcoin Use Proof of Work? Yes. It uses a PoW algorithm based on the SHA-256 hashing function in order to validate and confirm transactions as well as to issue new bitcoins into circulation.
How does Bitcoin create trust?

Which Crypto is proof-of-work?

The newer consensus mechanism is called proof of stake, and it powers Ethereum 2.0, Cardano, Tezos and other (generally newer) cryptocurrencies.
Which crypto uses proof-of-work?
Ethereum, like Bitcoin, currently uses a consensus protocol called Proof-of-work (PoW). This allows the nodes of the Ethereum network to agree on the state of all information recorded on the Ethereum blockchain and prevents certain kinds of economic attacks.
Is Ethereum a proof-of-work coin?
Ethereum currently relies on what’s known as proof-of-work, in which miners must complete complex puzzles to validate transactions and create new coins. This process requires a huge amount of computer power, and is often criticized due to its environmental impact.
Why is proof-of-work necessary?
Proof of work enables Bitcoin transactions to to be confirmed and recorded without a central authority. It disincentivizes attacks on a crypto’s blockchain by making verifying transactions expensive. Proponents of proof of work contend it’s more secure than other mechanisms like proof of stake.
Why is proof-of-work more secure?
Security. So far, proof-of-work has been the most proven way to maintain consensus and security within a distributed public network. This is because proof-of-work requires the initial cost of hardware and the ongoing expenditure of resources, rather than a single upfront expense to participate like proof-of-stake.
