Introduction
Blockchain is a form of digital database that can be used to store transactions, records and other data in a manner that makes them secure from tampering and revision. Using cryptography, blockchain technology allows users to conduct secure transactions with each other without the need for a third-party intermediary. In this article, we will look at how cryptography is used in blockchain technology to provide security for the transactions.
What Is Blockchain?
Blockchain is a distributed ledger technology (DLT). It is a chain of blocks that are linked together through cryptography. Each block contains a hash of the previous block, which links them all together in an unchangeable chain. The blockchain is not stored in one location; instead, it exists on thousands of computers around the world.
Cryptography in Blockchain
Blockchain is a distributed ledger. It is a list of transactions that have been recorded on multiple computers around the world and then synchronized with each other through cryptographic techniques. Each block in the blockchain contains information about one transaction, including details such as sender, receiver and amount transacted.
Cryptography is used to provide security for these transactions by ensuring that they are valid; this ensures that no one can tamper with or falsify any information stored on it. Cryptography also allows us to add blocks of data onto our blockchain without needing central authorities like banks or governments involved in approving them (this process is known as consensus).
How Does Blockchain Work?
Blockchain is a distributed ledger that records transactions between two parties. The blockchain is a chain of blocks, each block containing a hash of the previous block. The structure of these blocks makes it possible to verify any transaction on the network by tracing back to an earlier block in the chain and checking that its hash matches with what’s expected.
Each block contains a timestamp and transaction record (or multiple transactions). Blocks are linked together in chronological order using cryptography to create an immutable record for every single transaction ever made on the network.

Cryptography is a branch of mathematics that provides methods for secure communication in the presence of third parties. Cryptography can be used to encrypt data so that only authorized parties can read it, or it can be used to verify identity or validate an action by someone who has permission from another party (e.g., signing a contract). Blockchain technology uses cryptographic hashing functions and digital signatures to ensure that transactions are valid and cannot be altered after being recorded on a block chain ledger system.
