“On-chain” transactions carried out on a blockchain offer greater security and transparency because they're verified and recorded on a public distributed ledger that cannot be changed. To get a better understanding of on-chain transactions, this "What is on- chain transaction?" article can help you out.
What is on-chain transaction?
An on-chain transaction is a transaction that runs from beginning to end on the blockchain network. Once verified, the transaction is recorded on the public ledger of the blockchain network.
Here's how it works: When two parties want to trade cryptocurrencies, the information about the transaction is packed and timestamped into digital data collections called blocks. That block is sent to an associated blockchain network where it waits to be validated by computers in the network called nodes and added to the blockchain.
Different consensus mechanisms are used to verify transactions and add new blocks to a blockchain. Bitcoin, for example, uses a method called proof-of-work, which rewards miners for competing against each other using specialized computer software to solve extremely difficult computational puzzles to guess or match the "hash" and win the block reward.
Newer methods like proof-of-stake don't require mining computations but require participants to lock up a set amount of the native crypto token - their "stake" - to have a chance to be the validator for a block of transactions. Either process provides a high level of security and transparency because transaction data is public and constantly reviewed and updated by the network of miners or validators. However, due to the complexity of the process, it takes time to process each transaction and add it to the blockchain.
The advantages of the on-chain transactions are:
Security: Data stored on the blockchain is end-to-end encrypted and cannot be changed once recorded.
Decentralization: Blockchain is not subject to central governance bodies. This means there is virtually no risk of intermediaries violating trust or manipulating the flow of data.
Transparency: A distributed ledger means that transactions are recorded and verified simultaneously in multiple places. Blockchain Explorer allows anyone to trace a transaction back to a unique wallet address and view its activity, allowing claims and transactions to be verified independently.
The disadvantages of on-chain transactions are:
Slow Transactions: The speed of blockchain transactions depends on the number of transactions waiting to be processed in the queue, which can lead to network congestion.
High transaction fees: If the transaction volume is high, the network fees will also increase. Network usage can be very expensive during periods of high demand.
Power Consumption: The mining process inherent in the Proof of Work consensus mechanism consumes a large amount of computing power and energy.
