On-Chain

November 21, 2023 - Around 3 mins mins to read

In order to understand what on-chain transactions are, it is important to first understand the concept of blockchain. A blockchain system is essentially a network that contains a distributed ledger, which can be considered as a shared database. This ledger records all the transactions conducted on the blockchain and is shared with all participants, making it transparent and secure.

On-chain transactions refer to the transactions that occur directly on the blockchain. When a new transaction is conducted, a new block needs to be added to the blockchain. In order for the transaction to be considered valid and added to the blockchain, consensus protocols need to be followed. These protocols ensure that all participants in the network agree on the validity of the transaction.

Once a transaction is recorded on the blockchain, it is considered an on-chain transaction. These transactions are validated and authenticated by miners or authenticators, who verify the correctness of the transaction. This verification process ensures that the transaction adheres to the rules and protocols of the blockchain network.

Additionally, for an on-chain transaction to be considered complete, there needs to be a certain number of confirmations by the miners. Confirmations act as a validation mechanism for the transaction and ensure that it is secure and irreversible. The number of confirmations required may vary depending on the blockchain network and the level of security desired.

The time it takes for an on-chain transaction to complete can also depend on the network congestion. In some cases, when there is a high volume of transactions, there may be delays in confirming transactions. Miners need to prioritize transactions based on factors such as transaction fees, which can affect the speed of transaction confirmations.

It is important to note that on-chain transactions are the foundation of blockchain technology. They provide the immutability and security that makes blockchain a trusted system for conducting transactions. Each transaction added to the blockchain forms a chain of blocks, hence the name “blockchain”.

On-chain transactions differ from off-chain transactions, which are conducted outside of the blockchain. Off-chain transactions are typically faster and can be more scalable, but they rely on trusted third parties to facilitate the transaction process. In contrast, on-chain transactions are fully decentralized and do not require intermediaries.

An example of an off-chain transaction is a payment made through a payment platform like PayPal. When two parties engage in an off-chain transaction, they agree on the terms of the transaction outside of the blockchain. The actual transfer of funds and verification of the transaction occur within the payment platform, which acts as a trusted third party.

On the other hand, on-chain transactions eliminate the need for intermediaries and provide a trustless environment. The transparency and security of the blockchain network ensure that transactions are validated by multiple participants and recorded in a tamper-proof manner. This makes on-chain transactions ideal for applications that require high levels of security, such as financial transactions or supply chain management.

In conclusion, on-chain transactions are transactions that occur directly on the blockchain. They are validated, authenticated, and recorded on the distributed ledger by miners or authenticators. These transactions are secure, transparent, and provide a foundation for trust in blockchain networks. Understanding on-chain transactions is crucial for grasping the fundamental principles of blockchain technology.
