The ledger is the book in which the user’s transactions on the network are recorded. The ledger is like a book where everything is recorded to maintain security, privacy, and transparency in the network. It is shared among all the users on the network. 

What is Ledger in Cryptocurrency?

In the context of cryptocurrencies, a ledger is a database or a list of every transaction that has ever taken place on the network. This decentralized ledger, known as a blockchain, is maintained by a network of computers, or nodes, who work together to verify and record transactions.

  • A consensus mechanism, like Proof of Work or Proof of Stake, verifies each transaction on the blockchain to make sure it is legitimate and not fraudulent. The transaction is added to a block and then added to the blockchain when it has been confirmed.
  • A transaction that has been added to the blockchain cannot be changed or removed since the ledger is immutable. By doing this, fraud is avoided and the ledger’s integrity is guaranteed.
  • Users may follow the movement of cryptocurrency from one address to another using the ledger. This makes it possible to confirm the legitimacy of transactions and their owner, as well as to prevent double-spending.

In general, the ledger is essential to the functioning of a cryptocurrency network since it offers a safe and visible record of all transactions.

What is Distributed Ledger?

A computerized system for tracking asset transactions called distributed ledger technology (DLT) allows for the simultaneous recording of transactions and their associated information in numerous locations. Distributed ledgers lack a central data store and management features, in contrast to conventional databases.

  • A sort of database that is dispersed across numerous network nodes is a distributed ledger. It is a decentralized system that makes it possible to record and retain transactions safely and openly without the aid of a centralized body or middleman.
  • It is practically hard to tamper with or change the data recorded in distributed ledgers because they use cryptographic methods to maintain the validity and integrity of the data. Because of this, they are especially helpful for documenting financial transactions, digital assets, and other kinds of data that demand a high level of security and transparency.
  • There are other forms of distributed ledgers with various architecture and methods, but the blockchain is a particular version that employs a chain of blocks to record transactions. Directed acyclic graphs (DAGs) and hashgraph are two examples.

What is Blockchain Ledger?

A blockchain ledger is a distributed database that is maintained by a network of computers, which uses cryptography to ensure that each transaction is secure and cannot be altered retroactively without the consensus of the network. 

  • The ledger is made up of blocks, which contain a list of transactions, a timestamp, and a cryptographic hash of the previous block. 
  • Each new block is added to the chain in a linear, chronological sequence, forming a permanent, immutable record of all transactions that have occurred on the network. 
  • The decentralized nature of the blockchain ledger ensures that it is resistant to tampering, censorship, and fraud, making it an ideal platform for secure and transparent transactions. 
  • Blockchain technology is most commonly associated with cryptocurrencies like Bitcoin, but it has many other potential applications, such as supply chain management, voting systems, and digital identity verification.

Blockchain Ledger vs Distributed Ledger

ParameterBlockchain Ledger Distributed Ledger
Consensus mechanismA consensus method, such as proof of work or proof of stake, is used by blockchain ledgers to validate transactions and add new blocks to the chain. 
 
Distributed ledgers, on the other hand, employ a variety of consensus algorithms, including Paxos, Raft, and Byzantine Fault Tolerance.
ScalabilityDue to the consensus method and the requirement that every node validates every transaction, blockchain ledgers have come under fire for their poor scalability. 
 
On the other side, distributed ledgers can be more scalable since they leverage an efficient network of nodes to validate transactions.
 
ApplicationsBitcoin and other cryptocurrencies as well as other financial applications frequently employ blockchain ledgers.
 
Several sectors, including supply chain management, healthcare, and government, use distributed ledgers.
 
PermissionBlockchain ledgers come in both public and private varieties, with private blockchains only accessible to a few users.
 
Distributed ledgers can either be public or private, however, they are typically utilized in business contexts and require access rights.
 
StructureBlockchain is a distributed ledger that uses blocks of data connected in a chain using encryption, making it difficult to change.On the other hand, distributed ledgers use a network of nodes rather than a chain of blocks to jointly maintain a ledger.
