On-chain and off-chain transactions

Assalamu Alaikum friends, I came to talk about all the transactions that we do in the block chain and outside the block. Transactions are done through on chain and off chain. We will know about this transaction and try to find the difference between them. Let's start.


----------

On-chain transactions that take part on the blockchain. decentralized transparent and secure digital ledger that records cryptocurrency transactions. These transactions are verified and confirmed by the network make up the blockchain network and are stored. Each on-chain transaction results in a permanent record being on the blockchain. It is impossible to change them .

Off-chain transactions on the other hand transactions that outside of the blockchain network. These transactions are made on the blockchain to reduce transaction costs and time . Third-party payment processors typically facilitate off-chain transactions. For example many cryptocurrency exchanges use off-chain transactions to make cryptocurrency transactions faster . These transactions are not recorded on the blockchain but instead balances are adjusted and stored within the exchange's internal ledger.

It is important to note that off-chain transactions offer some advantages in terms of speed and cost. However, they generally have lower security guarantees than on-chain transactions.


**Here are some key features that distinguish on-chain and off-chain transactions.**

**On-Chain Transactions:**

* Clarity: On-chain transactions are publicly visible and transparent on the blockchain.
* Security: Every on-chain transaction is verified. The process is more secure when recorded by a network of decentralized nodes.
* Immutability: Once an on-chain transaction is confirmed and added to the blockchain it is permanent and cannot be changed.
* *Decentralization: On-chain transactions processed by a decentralized network. This ensures that no one has control over the transaction validation process.
* Higher fees and longer confirmation time: On-chain transactions often involve fees and require confirmation from the blockchain network, which takes some time.

**Off-Chain Transactions:**

* Motion: Off-chain transactions can be processed much faster than on-chain transactions. Because they don't require confirmation from the entire blockchain network.

* Scalability: Off-chain transactions can help overcome blockchain's scalability limitations.

* Low fees: Off-chain transactions generally incur lower fees than on-chain transactions. due to reduced network overhead.

* Confidentiality: Off-chain transactions can provide more privacy. because they are not publicly visible on the blockchain.

* Centralization: Off-chain transactions involve third-party intermediaries or payment processors and are transacted through a degree of centralization and reliance on trusted entities.



Hope you understand about these two transactions. Through these we transact our important assets. Trustworthiness is of course very important for offchain when doing transactions. Because it does not store any history or data online. Since it is run by individuals or entities, it carries more risk. Thanks everyone.
