What is blockchain select the best answer? ›

What is blockchain? Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).

Blockchain is an immutable digital ledger that enables secure transactions across a peer-to-peer network. It records, stores and verifies data using decentralized techniques to eliminate the need for third parties, like banks or governments. Every transaction is recorded, then stored in a block on the blockchain.

On the Bitcoin blockchain, a block is verified by miners, who compete against each other to verify the transactions and solve the hash, which creates another block. On the Ethereum blockchain, a block is validated by randomly selected nodes, which is must faster because there is no competition.

A blockchain is a distributed, immutable, and decentralized ledger at its core that consists of a chain of blocks and each block contains a set of data.

It's a type of distributed ledger technology (DLT), a digital record-keeping system for recording transactions and related data in multiple places at the same time. Each computer in a blockchain network maintains a copy of the ledger where transactions are recorded to prevent a single point of failure.

Healthcare

Blockchain can have a big impact on healthcare using smart contracts and healthcare is one of the biggest applications of blockchain. These smart contracts mean that a contract is made between 2 parties without needing any intermediary.

In the simplest terms, a blockchain is formed by stringing together different blocks. Each 'block' is a set of data or some kind of information – most commonly, transactions. Nobody 'owns' blockchain technology.

The blockchain commission is the fee that the sender pays for making a cryptocurrency payment. The fee is mandatory and serves 3 important functions: Goes to support miners/validators who help with process capture and validation of transactions in the blockchain.

How do you explain blockchain technology to someone who doesn't know it? ›

Blockchain technology is an advanced database mechanism that allows transparent information sharing within a business network. A blockchain database stores data in blocks that are linked together in a chain.

How Long Does It Take to Mine 1 Bitcoin? The reward for mining is 3.125 bitcoins. It takes the network about 10 minutes to mine one block, so it takes about 10 minutes to mine 3.125 bitcoins.

A Blockchain Validator is someone in charge of validating transactions on a blockchain. Every participant may become a blockchain validator by operating a full node on the Bitcoin Blockchain. However, the main reason to perform a complete node is to improve security.

If the transaction was supposed to be included in the next 25 blocks, I thought it will take around 250 minutes (~4hours) to be processed.

A blockchain is a decentralized, distributed and public digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network.

Blockchain technology is an advanced database mechanism that allows transparent information sharing within a business network. A blockchain database stores data in blocks that are linked together in a chain.

Blockchain is an encrypted, distributed database shared across multiple computers or nodes that are part of a community or system.

A blockchain is a decentralized, distributed, digital ledger consisting of records called blocks.
