What is sequential execution? Sequential execution, also known as Sequential Execution, is a resolution to execute and agree on each transaction before adding it to the block. So, if there is anything special about sequential execution, everyone will find out in the article below.

What is Sequential Execution?
Overview of Sequential Execution
In blockchain, when a transaction is sent to the network by a user, it is checked for validity and authenticated at the mempool before the transaction is included in the block. Sequentially, each transaction will be executed and agreed upon in such a manner. During this process, the transactions in the block will be processed sequentially, without interference from other transactions in the same block. That is Sequential Execution.
Sequential execution ensures blockchain integrity and accuracy of each transaction. Sequential execution is the standard process in executing and agreeing on the first transactions on the blockchain applied by Bitcoin, Ethereum,…
Pros & Cons of Sequential Execution
The advantages that Sequential Execution brings to blockchain include:
- High level of accuracy: The execution, validation and consensus of each transaction helps determine a valid transaction with almost 100% accuracy, thereby making the network secure and safe.
- Simple to deploy: Sequential execution is quite simple and easy to deploy, making the network less problematic when operating.
- Limit attacks on nodes because all nodes focus on processing one transaction at a time. This is also the disadvantage of Parallel Execution.
Some of the disadvantages of sequential execution include:
- The biggest disadvantage of sequential execution is the scalability of blockchains that apply sequential execution and suffer from slow transaction speeds.
- Sequential execution also contributes to high transaction fees on the blockchain network along with Mempool’s model.
- Blockchains that apply sequential execution if the network is not decentralized will also be vulnerable to DDoS attacks.
The Future of Sequential Execution
It is clear that in the context we see that many new generation blockchains such as Sui, Aptos, Monad, Linea or Fuel Labs begin to shift from Sequential Execution to Parallel Execution, will Sequential Execution blockchains be affected? pushed to the past or not? Of course not because this is not the biggest factor in deciding the survival of a blockchain.
A typical example is Bitcoin. Bitcoin has the Lightning Network which increases the processing speed of the blockchain, eases the limitations of sequential execution, and enhances its scalability. Even Ethereum itself does not need to move to Ethereum 2.0 because it can stay the same to build Layer 2 and then Layer 3.
In short, Sequential Execution will continue to play an important role in Blockchain and Blockchain itself has many ways to solve the scalability problem so Sequential execution is not the bottleneck. However, Parallel Execution will gradually become more popular in the crypto market.
