How Transactional Throughput and Finality Contribute to Security

Zenith Chain· 4 min read

In the world of Blockchain, many moving parts must work together for the system to function correctly. One of the first-mentioned topics is security. It’s no secret that Blockchain is secure. In fact, that’s one of the big selling points.

But how does Blockchain achieve this?

In part, one component is transactional throughput, which measures how many transactions can be processed by the network in a given period. Another is finality, which is the assurance that once a transaction is committed to the Blockchain, it cannot be reversed or modified.

In this article, we’ll explore how these two factors contribute to the security of the Blockchain.

Transactional Throughput

Transactional throughput is the number of transactions processed in a given time frame. For example, if a blockchain can process ten transactions per second, its transactional throughput would be ten tps. The higher the transactional throughput, the more secure the Blockchain. That’s because a high transactional throughput ensures that blocks are added to the chain frequently. This, in turn, makes it more difficult for attackers to alter transaction data without being detected.

Transactional throughput is vital for security because it helps to ensure that all transactions are processed promptly. If there are too many unconfirmed transactions, it becomes more challenging to determine which ones are valid and which ones are not. This can lead to double-spending or someone trying to spend the same coins more than once.

By processing transactions quickly, transactional throughput helps to prevent these types of attacks.

It’s important to note that not all blockchains are created equal when it comes to transactional throughput. For example, Bitcoin has a transactional throughput of around five tps, while Ethereum has a transactional throughput double that of bitcoin. This means Ethereum is more secure than Bitcoin because it can process transactions more quickly and add them to the chain faster.

Of course, other factors contribute to security in Blockchain beyond transactional throughput. But it’s one of the most important ones. So, if you’re looking for a secure blockchain platform for your business, pay attention to its transactional throughput.


Finality is also vital for security because it allows users to trust that it cannot be reversed or modified once a transaction is committed to the Blockchain. This means that users can be confident that their coins will not be stolen or lost due to someone else’s malicious actions. In addition, finality prevents attacks where someone tries to roll back the Blockchain to spend their coins more than once.

It refers to the permanence of a transaction. Once a transaction is finalized, it cannot be altered or reversed. This quality is what makes Blockchain so secure. When you combine finality with decentralization, you get a distributed ledger system that is incredibly difficult to hack.

We’re always doing transactions on Blockchain, but especially when we send a trustless system something of value, there needs to be an assurance that it won’t get reversed.

To understand why finality contributes to security, it helps to know a little bit about how Blockchain works. Essentially blocks in a blockchain contain a record of all the transactions that have taken place since the last block was created. These transactions are verified by the computers in the network (i.e., the nodes), and each node has an identical copy of the transaction history.

When a new transaction is initiated, it is broadcasted to all the nodes in the network. The nodes then verify the transaction and add it to their respective copies of the ledger. Once a transaction is added to a block, it cannot be altered or reversed — hence the term “finality.”

Finality is what makes Blockchain so secure. Since each transaction is irreversible, there is no way for someone to change the ledger without being detected. Hackers would need to hack into every single node in the network simultaneously to modify the ledger, which is nearly impossible.

In addition, because each node has its copy of the ledger, it would be tough for someone to tamper with all of them without being detected. This decentralized nature of Blockchain makes it incredibly secure.

The security of Blockchain is unbreakable because once a well-formed block has been added to the chain, it cannot be revoked.

Finality is vital in blockchain consensus protocols, but it only happens after a period. For transactions to be considered final, you have to wait for confirmation before they’re confirmed.

Zenith Chain Is Fast and Secure

Closing thoughts

Transactional throughput and finality are necessary for security because they help prevent double-spending and other attacks. By ensuring that all transactions are processed quickly and that once a transaction is committed, it cannot be reversed, these two factors help to keep the Blockchain secure.
