One of the basic things you need to know before you start buying crypto is how blockchain transactions work. Two different transaction types can be done on the blockchain: on-chain and off-chain.

The main difference between on-chain and off-chain blockchain transactions is that on-chain transactions occur directly on the blockchain, while off-chain transactions occur outside of the main blockchain network, using secondary channels or layers.

Today we’re going to discuss them both and understand the difference between them. But first, let’s talk a bit about the blockchain itself.

Understanding Blockchain - what’s a distributed ledger?

A distributed ledger is a database shared and synchronized across various countries, sites, institutions and accessed by multiple people. The blockchain is a distributed ledger that records, synchronizes, and shares all transactions in an electronic database.
How does it work exactly? Independent computers that are called nodes track and record all blockchain transactions and other data in their electronic ledgers. Each participant at a node of the network can access the data shared across the network and own a copy of it. All this data is organized in blocks chained together, thus creating the blockchain.

The other type of ledger that banks use is a centralized ledger, which can be more prone to fraud and cyber-attacks. Centralized or general ledgers work as a central repository for accounting data that is transferred from any sub-ledgers. They’re the foundation of any accounting system. They involve a third party that controls the entire system, rendering them less secure.
There is no need for a third-party oversight with distributed ledgers, making them perfect for cryptocurrency. Using the proof-of-work method, users can validate transactions on the blockchain without dealing with an intermediary. Another advantage of these ledgers is their decentralized nature that makes them very secure. They are not easy to hack, and their shared data is highly transparent. Distributed ledgers are also immutable and tamperproof. A user cannot alter their data, which gives the blockchain an added layer of protection.

On-chain transactions

This type of blockchain transaction is considered valid when transacted on the public, decentralized ledger. Users verify transactions and validate them. In order for a transaction to be considered valid, all the validated signatures from the users are required to be an exact match. Each transaction is published on the public blockchain, where it can be inspected, ensuring transparency, as it cannot be changed or reverted once published. Some drawbacks of on-chain transactions are the slow speed at which they are performed and the higher costs, as the transaction fees can be pretty hefty.

Off-chain transactions

Transactions that move the value outside of the blockchain are called off-chain transactions. Simply put, these transactions take place outside of the blockchain itself. Some methods through which to execute these transactions are either a transfer agreement between the two parties involved or adding a third party that guarantees that the transfer will be honored.
Compared to their on-chain counterparts, off-chain transactions offer some advantages, like low fees and faster execution. They also ensure the complete anonymity of the participants, as the details of the transaction are not publicly broadcasted. Both types of transactions are suitable depending on their main use. On-chain transactions are ideal for cryptocurrency transfers. Off-chain is preferred by some users that bundle multiple transactions of this sort into a single on-chain one, achieving a similar effect.

Both types of transactions have benefits and drawbacks when it comes to the gaming industry. On-chain transactions provide complete transparency, a significant advantage, but can incur higher fees. Off-chain transactions might be faster, but they offer less transparency.

Questions of interest

How do on-chain transactions impact the blockchain network?

On-chain transactions impact the blockchain network by directly adding data to the main blockchain, which increases the size of the blockchain and requires nodes to verify and process the transaction. This can slow down the network and increase transaction fees, particularly during periods of high network activity.

How do off-chain transactions affect transaction fees?

Off-chain transactions can help reduce transaction fees by moving some transactions off the main blockchain network and onto secondary channels or layers. This can help alleviate network congestion and reduce the load on the main blockchain, leading to lower fees for on-chain transactions.

Can on-chain and off-chain transactions be used together in a single blockchain network?

Yes, on-chain and off-chain transactions can be used together in a single blockchain network. In fact, many blockchain projects are exploring the use of off-chain scaling solutions, such as the Lightning Network, to help reduce network congestion and improve transaction speeds while still leveraging the security and immutability of the main blockchain.
