SUMMARY
A blockchain is a chain of blocks containing information. Since one block is connected to another, it becomes difficult to alter data, making blockchain highly secure and unalterable. Though blockchain and decentralization are generally interrelated, not all blockchains are decentralized.
Blockchains can be centralized or decentralized based on their participants’ rights to make transactions. In a decentralized blockchain, anyone can participate and make transactions, whereas on a centralized blockchain, only a few people will be decision-makers.
Let’s explore what makes the blockchain decentralized, the difference between a decentralized blockchain and a centralized blockchain, and more in this comprehensive blog.
What is Decentralization in a Blockchain?
Blockchain decentralization involves distributing power and authority equally to all participants in the network rather than a single entity governing the network. For instance, in a centralized blockchain, the network of computers or nodes collectively validate a blockchain.
On the other hand, a traditional centralized blockchain relies on a central entity to verify and validate transactions. A decentralized blockchain is created to eliminate the need for intermediaries by allowing multiple participants to manage the system collectively.
Each node can access the entire blockchain and participate in transaction validation. The consensus mechanism of the blockchain ensures the security, reliability, and integrity of the network.
Decentralized blockchain is used across multiple industries for the numerous benefits it offers. The popular examples of decentralized blockchain include Bitcoin and Ethereum.
What makes a Blockchain Decentralized?
A blockchain is decentralized due to its underlying technology and infrastructure. Here are a few prime features that make a blockchain decentralized.
1. Distributed Ledger Technology
The blockchain has a distributed ledger that records all transactions and stores them across multiple nodes in the network. Every node maintains a complete copy of the blockchain, making a distributed ledger. The ledger is synchronized via consensus mechanisms.
2. Consensus Mechanisms
Decentralized blockchains leverage consensus mechanisms like Proof of Work (PoW) and Proof of Stake (PoS), enabling various network participants to verify and validate transactions that occur on the blockchain. Every node should accept the transaction, eliminating the need for central authority.
3. Peer-to-Peer (P2P) Network
Blockchain networks work like a peer-to-peer network architecture, encouraging participants to connect with each other without a central authority. Each node coordinates with other nodes to create new blocks while maintaining the integrity of the blockchain.
4. Decentralized Governance Model
Blockchain networks often implement decentralized governance models to make decisions regarding protocol upgrades and enhancements via a consensus-driven process. That enables stakeholders in the network to participate in blockchain governance, eliminating the need for intermediaries.
5. Immutability
Blockchain leverages cryptographic algorithms to ensure the integrity and security of data stored in the network. Once added to the chain, the block is permanent, and it is impossible to alter past transaction data as it demands acceptance from numerous participants.
That makes the blockchain immutable, keeping the integrity of the network intact while preventing it from tampering and manipulation.
Types of Decentralization in a Blockchain
Let’s analyze the prominent types of decentralization in a blockchain.
1. Architectural Decentralization
It is one type of decentralized blockchain that primarily emphasizes the physical infrastructure and network architecture. The decentralization here means the distribution of nodes or computers that participate in the network across various locations and organizations.
The logic is to prevent a single point of failure and enhance resilience against blockchain attacks and disruptions.
2. Data Decentralization
It is another type of decentralized blockchain that predominantly focuses on the distribution of data across the network. The data in this blockchain is ideally replicated and stored across various nodes, ensuring redundancy while preventing a single point of failure.
The redundancy here improves the security and censorship resistance of the blockchain.
3. Governance Decentralization
Governance decentralization is all about distributing the decision-making authority among network participants in the blockchain network. Thus, every network participant can govern the network through mechanisms like voting, consensus protocols, or decentralized autonomous organizations (DAOs) rather than having a single central authority making decisions.
Governance decentralization ensures fair and democratic decision-making procedures.
4. Incentive Decentralization
It is one of the most popular decentralized blockchains that involves distributing rewards or incentives across the network, encouraging network participants to contribute fairly to the blockchain.
Most blockchain networks incentivize participants through consensus mechanisms like mining rewards or token-based economies. Incentive decentralization helps maintain the integrity and security of the blockchain by fairly distributing the incentives across the network participants.
5. Functional Decentralization
Functional decentralization involves distributing specific functions or tasks across the network. For example, various participants perform different activities like mining, validating transactions, maintaining consensus, and executing smart contracts. That ensures a more inclusive and robust blockchain as multiple functions are distributed and performed by concerned experts.
Advantages and Disadvantages of Decentralization
Let’s discuss the advantages and disadvantages of decentralized blockchain to better understand the functionality of decentralized blockchain.
Advantages
1. Reliability
Unlike traditional payment systems, decentralized blockchain is not amidst two parties. In fact, one needs no permission or trust from other parties to transact in the decentralized blockchain network.
Since it uses distributed ledger technology to record all transactions, these blockchains are transparent and unalterable, making them more secure and reliable.
2. Accuracy
Data accuracy is way better in a decentralized blockchain. Data is siloed and copied from one ledger to the next, making it impossible to alter, manipulate, or damage. Hence, data is more accurate and transparent in a decentralized blockchain.
3. Transparency
The data is available to the public in decentralized blockchains, enabling every user to see and track them. A transparent blockchain ensures the reliability and integrity of the blockchain.
4. Immutability
The data stored in the decentralized blockchain is unalterable. Since every node in the blockchain network should confirm every alteration, it is challenging to alter data in the blockchain network.
5. Security
Decentralized blockchains are far more secure than centralized blockchains as they implement encryption techniques to protect data.
Disadvantages
1. Expensive
A decentralized network can cost you more than a centralized network as it demands more systems and resources to run it.
2. Messy
Since many people are involved in the process and there is no single authority to control it, everyone will have a different say on an issue. That can make the process messy and difficult to come to solutions at times.
3. Unorganized
If the users involved in the decentralized network don’t do their intended jobs on time, as they have no centralized authority to question them, the network will suffer at the end of the day.
CONCLUSION
The decentralization of blockchain is determined by its architecture and governance. Simply put, factors like the distribution of nodes, the consensus mechanisms employed, and the level of transparency in protocol updates and decision-making processes determine the decentralization of the blockchain.
Though not all blockchains are decentralized, most of them are. Decentralized blockchains are preferable to centralized ones as they enhance the reliability, security and integrity of the applications built on them.

FAQs ON BLOCKCHAIN
-
Are all blockchains decentralized?
No, not all blockchains are decentralized. Some blockchains, especially private or permissioned ones, are controlled by a central authority, making them more centralized.
-
What is the difference between centralized and decentralized governance in blockchains?
Centralized governance involves decision-making by a select group or authority, while decentralized governance distributes decision-making power across the entire network, often through consensus mechanisms or voting.
-
What role does the consensus mechanism play in decentralization?
Consensus mechanisms like proof of work (PoW) and proof of stake (PoS) are crucial for decentralization. They ensure that all nodes in the network agree on the state of the blockchain, preventing any single entity from having influence.
