Blockchain technology has captured the world’s attention and reshaped the way we interact with digital assets. However, scalability and security challenges have posed significant obstacles to its widespread adoption. NEO, a smart contract platform, has developed a unique consensus algorithm called delegated Byzantine Fault Tolerance (dBFT) that addresses these issues.
In this article, we will delve into the world of NEO and explore how its dBFT algorithm tackles these challenges head-on. Additionally, you can start trading and be on top of others. Want to know how? Start using Coin GPT now and start automated trading.
What is dBFT Consensus Algorithm?
Blockchain relies on consensus algorithms to establish trust and agreement among network participants. Delegated Byzantine Fault Tolerance is a consensus algorithm developed by NEO that aims to provide a fast and secure way to validate transactions on the blockchain. With dBFT, NEO ensures reliable consensus, block finality, and enhanced performance. It is an improved version of the traditional Byzantine Fault Tolerance (BFT) algorithm, which is known for its high level of fault tolerance.
The principle behind dBFT is to have a group of trusted nodes, known as consensus nodes, that are responsible for validating transactions and creating new blocks. These consensus nodes are elected by NEO token holders through a voting system, and they have the power to verify transactions and add them to the blockchain.
One of the key features of dBFT is its ability to prevent forks in the blockchain. In traditional BFT algorithms, forks can occur if there are conflicting views on which block to add to the chain. In dBFT, consensus nodes work together to agree on a single valid block to add to the chain, ensuring that there is only one version of the truth on the blockchain. This prevents transaction reversal, preventing chain forks, and allows the chain for immediate settlement of all transactions on the network.Â
Moreover, dBFT provides a high level of security by enabling Byzantine fault tolerance, which means that the system can tolerate up to one-third of its nodes being faulty or malicious without compromising the integrity of the blockchain. This is achieved by ensuring that consensus nodes communicate with each other to verify transactions and prevent any malicious activity from occurring.

Advantages of dBFT: Powering Blockchain to New HeightsÂ
- Efficiency:
One of the main advantages of dBFT is its ability to improve the efficiency of the blockchain with fast block confirmations. Compared to other consensus algorithms, dBFT can process a higher number of transactions per second (TPS) while maintaining a high level of security.
The reason for this increased efficiency is due to the delegation of validation power to the consensus nodes. Rather than requiring all nodes on the network to validate transactions, dBFT only requires a small number of trusted consensus nodes to do so. This reduces the computational power required to validate transactions, which results in faster processing times and higher TPS.
- Scalability:
NEO’s dBFT algorithm enables the network to handle increased demand without sacrificing performance or decentralization, by supporting parallel transaction processing and optimizing resource allocation.
They have implemented a feature called UTXO coalescing, which combines multiple unspent transaction outputs (UTXOs) into a single UTXO, reducing the size of the blockchain and increasing transaction throughput.
- Transaction Finality:
In dBFT consensus, NEO token holders vote to elect a set of consensus nodes; a delegated group responsible for producing blocks. These nodes commit a new block to the blockchain only after a â…” majority is achieved among them.Â
As each potential block must receive full network consensus before being accepted, transactions in Neo have absolute finality as soon as they are confirmed in a single block.
- Security:
dBFT safeguards the NEO network against malicious actors by requiring nodes to prove their identity, preventing compromises and enhancing security. Neo uses a digital identity system, which allows users to verify their identities and streamline the transaction process. This feature not only reduces the time required to verify a user’s identity, but it also prevents fraud and ensures that only authorized users can access the blockchain.Â

Now, before we move on to the Real World Applications of NEO, let’s take a closer look on at the security enhancements of the NEO blockchain.
Security Enhancements of NEO using dBFTÂ
Security is a critical aspect of blockchain technology, and dBFT is designed to provide a high level of security to prevent any malicious activities on the network.
Byzantine fault tolerance is a property of a distributed system that enables it to function correctly and securely even when some of its nodes fail or behave maliciously. In the context of blockchain technology, this means that the system can tolerate up to one-third of its nodes being faulty or malicious without compromising the integrity of the blockchain.
dBFT achieves Byzantine fault tolerance by requiring consensus nodes to communicate with each other to verify transactions and prevent any malicious activity from occurring. If any consensus node behaves maliciously, the other nodes can detect and isolate it, preventing it from affecting the integrity of the blockchain.
Another security enhancement of dBFT is its ability to prevent double-spending attacks. Double-spending attacks occur when a user spends the same cryptocurrency twice, leading to a loss of funds for the recipient. With dBFT, transactions are validated and added to the blockchain in a timely manner, ensuring that there is no opportunity for double-spending.
Moreover, dBFT also has a mechanism for preventing Sybil attacks, which occur when a malicious user creates multiple identities to gain control of the network. In dBFT, the consensus nodes are selected through a voting system, which ensures that only trusted nodes are allowed to participate in the consensus process.
