What is a blockchain? A definition of the distributed ledger technology
blockchain is as follows:
A blockchain is a distributed database that maintains a continuously growing list of digital “blocks”, each of which contains a cryptographic hash of the previous block, a timestamp, and transaction data. Each block is linked to the previous block through a cryptographic chain. Bitcoin and other cryptocurrencies use blockchain technology to create an open, digital ledger of economic transactions.
What is a blockchain? Understanding the distributed ledger technology
A blockchain is a distributed ledger technology that serves as a public record of all cryptocurrency transactions. It is essentially a digital ledger of all cryptocurrency transactions that are verified and stored by nodes on the network. The blockchain is unique in that it allows for secure, transparent, and tamper-proof recording of transactions. This makes it an ideal tool for tracking the ownership of digital assets.
What is a blockchain? An introduction to the distributed ledger technology
that underpins cryptocurrencies like Bitcoin.
A blockchain is a distributed ledger technology that underpins cryptocurrencies like Bitcoin. It is a tamper-proof system that allows for secure, transparent and tamper-resistant transactions. Transactions are verified by network nodes and recorded in a public “block chain”. Bitcoin and other cryptocurrencies are based on blockchain technology.
What is a blockchain? The basics of the distributed ledger technology
that underlies cryptocurrencies like Bitcoin are explained here.
A blockchain is a digital ledger of all cryptocurrency transactions. It is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
The decentralized nature of blockchains makes them difficult to tamper with. Bitcoin, for example, uses cryptographic proof to verify the validity of each block, making it virtually impossible for anyone to modify the ledger without being noticed.
What is a blockchain? How the distributed ledger technology works
A blockchain is a digital database that allows for secure, transparent and tamper-proof record keeping. The technology works by creating a continuously growing list of records, called blocks, that are linked and secured using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp and transaction data. Bitcoin and other cryptocurrencies are based on blockchain technology.
What is a blockchain? Applications of the distributed ledger technology
(DLT) are proliferating, but what is a blockchain?
A blockchain is a distributed ledger technology that facilitates secure, transparent and tamper-proof transactions. It uses a distributed database that is constantly growing as "completed" blocks are added to it with a new set of recordings. Each block contains a cryptographic hash of the previous block, a timestamp and transaction data. Bitcoin and other cryptocurrencies are based on a blockchain.
What is a blockchain? The future of the distributed ledger technology
A blockchain is a distributed ledger technology that enables a secure, transparent and tamper-proof record of transactions. The technology is built on a decentralized platform and uses cryptography to secure data. It is often described as a “distributed database” because it allows multiple parties to access and update information without the need for a middleman.
