What is On-chain? A Guide for Crypto Users [2023]

Updated 2023-07-21 16:04:51

Cryptocurrency transactions can be facilitated via blockchain technology without the involvement of a reliable third party, such as a bank. In general, a blockchain system is a network that consists of a distributed ledger, which is similar to a common database. On-chain transactions are those that are completed and shared among all participants on the blockchain itself. A blockchain's "on-chain" transactions provide more security and transparency because they are validated and stored on an immutable public distributed ledger. This article will include a brief explanation of On-chain transactions, their benefits, and their disadvantages.


What is On-Chain?

On-chain transaction is a transaction that is completed entirely on a blockchain network


On-chain transaction is a transaction that is completed entirely on a blockchain network. The transaction is then confirmed and added to the public ledger of a blockchain network. Depending on the network protocol, a transaction becomes nearly irreversible after it receives enough confirmations from other network users based on the network's consensus mechanism. Usually, the transaction can only be undone if a majority of the blockchain's hashing power agrees to do so. This can enable the high secure feature to the crypto users.


The network's users, known as miners, must verify each transaction that takes place on a blockchain. A transaction is only considered to be genuine once all parties have agreed that it is valid after being independently verified. The transaction information is subsequently transmitted to network users and recorded on the block.


On-Chain vs Off-Chain

On-Chain Vs Off-Chain


On-chain transactions are transactions that happen directly on a blockchain network. These transactions are verified, and then they are permanently recorded on the blockchain.


Meanwhile, off-chain transactions take place away from the blockchain network. These transactions are handled through other procedures and channels outsite the blockchain. Here are the differences among on-chain and off-chain.



On-chain transactions refer to the exchange or modification of digital assets or tokens that occur in a blockchain network. These can be exchanges of cryptocurrencies, communications between smart contracts, or any other operations requiring alterations to the state of the blockchain.


Off-chain transactions may utilize established payment systems and centralized databases for the procedure. These transactions could involve acts like money transfers between accounts on a centralized exchange or the use of payment systems. It also tends to have a cheaper transaction fee for each transaction.



The on-chain transactions are publicly visible and anyone in the network can view the transaction details including the send and receiver address, the transaction amount and transaction timestamp. This visibility can increase the trust and operability of the network.


The visibility of off-chain transactions on the blockchain is depend on the specific implementation. The blockchain may record the settlement of these transactions, but the specifics of each transaction are not made available to the public. This can be useful for privacy-focused cases.


Ability to Scale

The underlying blockchain technology can have an impact on how scalable on-chain transactions are. Due to their consensus methods, public blockchains can only scale to a certain extent, which results in slower transaction processing times and higher fees during times of intense network congestion. To overcome these scaling issues, various solutions and blockchain improvements are being created.


Compared to on-chain transactions, off-chain transactions may provide better scalability. These approaches can perform a bigger volume of transactions with less network congestion and lower fees by completing transactions outside the blockchain. Off-chain solutions are designed to address the scalability issues of on-chain transactions, particularly with regard to throughput and speed.


Trust and Security

On-chain transactions get advantages from the security provided by the underlying blockchain protocol. Digital signatures and consensus procedures are frequently used to protect transactions. A transaction is very secure and immutable once it is approved and uploaded to the blockchain, making it very difficult to change or tamper with.


The procedures utilized to settle these transactions have an impact on the security of off-chain transactions. For the security and integrity of off-chain transactions, some systems use cryptographic techniques, while others may add centralized components or trusted intermediates. Depending on the particular implementation, the security level may vary.


Benefits of on-chain transactions

5 Benefits of on-chain transactions


There are several benefits that can be provided from on-chain transactions. They are decentralization, high security, immutability, transparency, and global accessibility.


1) Decentralization

On-chain transactions assist in the decentralization of power and control. Rather than relying on centralized institutions or authorities, blockchain networks allocate decision-making and transaction validation among network participants (nodes). This decentralization helps build a more inclusive, resilient, and censorship-resistant financial and economic infrastructure in a blockchain network. Moreover, interacting with decentralized applications (DApps) requires on-chain transactions. To allow numerous features, including token transfers, smart contract executions, decentralized finance (DeFi) operations, and more, these DApps make use of on-chain transactions.


2) High Security

The strong security offered by the underlying blockchain protocol is advantageous for on-chain transactions. Through cryptographic techniques like digital signatures and consensus procedures, transactions are protected. Blockchain networks are particularly resistant to attacks and unauthorized modifications due to their decentralized structure, offering a high level of security.


3) Immutability

Blockchain is immutable and cryptographic hashing techniques are used to safeguard on-chain transactions. A procedure known as hashing transforms the transaction data into a fixed-length string of characters called a hash when a transaction is created. Since the hashing operation is intended to be irreversible, it is quite challenging to extract the actual transaction data from the hash. A hash value would change if the exchanged data were altered in any way. Thus, an on-chain transaction is nearly impossible to change after it has been verified and uploaded to the blockchain. Blockchain technology's decentralized and distributed structure makes sure that transaction records are irreversible and difficult to manipulate. The security and integrity of transactions are increased by this immutability.


4) Transparency

On the blockchain, on-chain transactions are openly viewable and transparent. Within the network, this transparency encourages trust and responsibility. In order to increase transparency and lower the risk of fraud or manipulation, participants can check transaction specifics and monitor the movement of funds. Anyone can examine a transaction's activity and track it back to a specific wallet address using a blockchain explorer, enabling independent verification of claims and transactions.


5) Global Accessibility

Every user on the blockchain network can access on-chain transactions. Blockchain networks frequently offer open participation and governance frameworks, making it possible for anyone from all over the world to check every detail of transactions providing the trust of the network to the crypto users. By giving unbanked or underbanked people access to financial services, on-chain transactions have the potential to advance financial inclusion. People can engage in on-chain transactions and utilize the numerous financial services made available on blockchain networks as long as they have a smartphone, computer, and internet connection.


In general, on-chain transactions offer numerous benefits such as security, transparency, trustlessness, decentralization, and global accessibility. While there are challenges such as scalability and privacy concerns, the advantages of on-chain transactions outweigh the drawbacks, making them a valuable component of blockchain technology.
