How does bitcoin consensus work
The Bitcoin consensus is about transaction rules, transaction states, and Bitcoin values [4]. It is agreement of rules that determinate which blocks and transactions are valid or not, agreement of which transactions have occurred, and agreement of that bitcoins have value and players want accept bitcoins in payment.
How does consensus protocol work?
Conclusion. The consensus protocol is the guarantee for the stable operation of blockchain systems. Nodes agree on a certain value or transaction through the consensus protocol.
How does Nakamoto consensus work?
In the Nakamoto Consensus, there is no block selection “voting” process like in BFT-only networks; instead, the miners compete to solve a cryptographic puzzle, and the winner (and their new block) is then accepted as valid across the entire network of miners.
Is Bitcoin able achieve complete consensus?
Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
Can blockchain work without solving consensus?
It is therefore important to wisely choose one as per the business network requirement because Blockchain networks cannot function properly without the consensus algorithms to verify each and every transaction that is being committed.
Why is consensus hard in blockchain?
The miners solve cryptographic puzzles to “mine” a block in order to add to the blockchain. This process requires immense amount of energy and computational usage. The puzzles have been designed in a way which makes it hard and taxing on the system.
What is longest chain rule?
The longest chain is what individual nodes accept as the valid version of the blockchain. The rule that nodes adopt the longest chain of blocks allows every node on the network to agree on what the blockchain looks like, and therefore agree on the same transaction history.
What consensus does Bitcoin use?
proof of work (PoW)
Bitcoin uses proof of work (PoW) as its consensus protocol, which is energy and time-intensive. The rate of verification of transactions in Bitcoin is relatively slow compared to Visa and MasterCard’s likes.
What is proof of burn?
Proof of burn (POB) is an alternative consensus algorithm that tries to address the high energy consumption issue of a POW system. POB is often called a POW system without energy waste. It operates on the principle of allowing miners to “burn” virtual currency tokens.
What is consensus in Crypto?
A consensus mechanism is a fault-tolerant mechanism that is used in computer and blockchain systems to achieve the necessary agreement on a single data value or a single state of the network among distributed processes or multi-agent systems, such as with cryptocurrencies.
What is proof-of-work in crypto?
Proof of work (PoW) is a decentralized consensus mechanism that requires members of a network to expend effort solving an arbitrary mathematical puzzle to prevent anybody from gaming the system. Proof of work is used widely in cryptocurrency mining, for validating transactions and mining new tokens.
What are protocols in Crypto?
Definition. Protocols are basic sets of rules that allow data to be shared between computers. For cryptocurrencies, they establish the structure of the blockchain — the distributed database that allows digital money to be securely exchanged on the internet.
What is the best crypto protocol?

Is bitcoin a network or protocol?
The bitcoin network is a peer-to-peer payment network that operates on a cryptographic protocol. Users send and receive bitcoins, the units of currency, by broadcasting digitally signed messages to the network using bitcoin cryptocurrency wallet software.
Are all cryptocurrencies protocols?
Like the internet, cryptocurrencies have protocols. Any cryptocurrency – Bitcoin, Ethereum, XRP – has its own distinct protocol. Cryptocurrency protocols only allow the functioning of a few applications – sometimes only the application of the cryptocurrency itself.
Is Ethereum a blockchain?
Ethereum is a decentralized blockchain platform that establishes a peer-to-peer network that securely executes and verifies application code, called smart contracts. Smart contracts allow participants to transact with each other without a trusted central authority.

Why is blockchain called blockchain?
Why is it Called “Blockchain”? Blockchain owes its name to how it works and the manner in which it stores data, namely that the information is packaged into blocks, which link to form a chain with other blocks of similar information.
Can blockchain be hacked?
Since blockchain is supposed to be extremely secure and unalterable, many individuals have dubbed this technology as “unhackable”. However, recent incidents have unfortunately shown that hackers can access blockchains in certain situations.

How do you explain blockchain to a child?
A Blockchain (or block chain) is a method of storing a list of entries, which cannot be changed easily after they are created. This also applies to the list. This is done by using several concepts from cryptography, including digital signatures and hash functions.
How would you explain blockchain to a 5 year old?
Blockchain is basically a network of computers called nodes which all have same history of transactions. So instead of one company or a database which holds all the information, now the information is spread across whole of the network.
