What is a blockchain in technology?
Blockchain is a system of recording information that makes it difficult or impossible to alter, hack or spoof the system. A blockchain is essentially a digital ledger of duplicated transactions distributed across a network of computer systems on the blockchain.
A blockchain is a growing list of records, called blocks, linked together using cryptography. Each block consists of a cryptographic hash of the previous block, a timestamp, and transaction data (usually represented as a Merkle tree).
The timestamp proves that transaction data was present when the block was published to bring it to its hash. Since each block contains information about the block preceding it, they form a chain, with each additional block reinforcing the one before it.
Therefore, blockchains are resistant to modification of their data because once recorded, the data in any block cannot change retroactively without changing all subsequent blocks.
What is a Blockchain Technology Example?
A blockchain is a series of blocks that contain information. The data stored inside a block depends on the type of blockchain. For example, a bitcoin block contains information about the sender, receiver, number of bitcoins to be transferred. The first block in the chain is called the genesis block.
What is Blockchain vs. Cryptocurrency?
Blockchain is the technology that enables the existence of cryptocurrency (among other things). Bitcoin is the name of the most famous cryptocurrency, for which this technology was invented.
Most cryptocurrencies use blockchain technology to record transactions. For example, both the Bitcoin network and the Ethereum network are based on the blockchain.
On 8 May 2018, Facebook confirmed that it would open a new blockchain group led by David Marcus, who was previously in charge of Messenger. Facebook’s planned cryptocurrency platform, Libra (now known as Diem), was formally announced on June 18, 2019.

Blockchain is the technology that underlies bitcoin and was developed specifically for bitcoin. So, bitcoin was the first example of blockchain in action, and without blockchain, there would be no bitcoin. So although bitcoin uses blockchain technology to trade digital currency, blockchain is more than just bitcoin.
What are the disadvantages of Blockchain technology?
- Blockchain is not a distributed computing system
- Scalability is an issue
- Some blockchain solutions consume a lot of energy
- Blockchain cannot go back – data is immutable
- Blockchains are sometimes inefficient
- Not completely safe
- Users are their bank: private key
Why is blockchain so valuable?
Bitcoin’s underlying technology, called the blockchain, is tested and used as a payment system. One of its most effective use cases is increasing speed and reducing cross-border remittances costs.
Who is using the blockchain?
