The Blockchain is one of the most recently coined terms in the world of technology, but do you know what it is? As you may have guessed, blockchain is a shared database that serves as a ledger for the registration of purchase-sale transactions and other transaction types.
Its emergence coincided with bitcoin’s; in fact, it is the data encoding system that employs this virtual currency. In a short period, the enormous potential that it possessed beyond finance was Because of its technical solidity. This technology enables more processing in a company’s back-end. It also allows multiple sharing of information across organizational and system boundaries without jeopardizing data integrity, capital flow automation, and auditing at any level.

What Is Blockchain?
Blockchain is a decentralized digital ledger that keeps records of the transactions made on several computers in a secure and transparent manner. To a network of computers rather than one central server, blockchain spreads the data, thus, it becomes tamper-proof and reliable.
The record of all the transactions (blocks) that are made on the blockchain stored in the block contains a timestamp as well as a cryptographic link to the previous block. This means that the data can no longer be modified.
Simply put: Blockchain is a database that is shared between parties and the stored data are there forever and are very safe without the need for a middleman.

How Does Blockchain Work? (Step-by-Step Process)
| Step | Process | What Happens |
| 1. Transaction Initiation | A user requests a transaction | Someone sends crypto, records data, or executes a smart contract on the blockchain |
| 2. Transaction Broadcast | Transaction is sent to the network | The request is broadcast to a peer-to-peer (P2P) network of nodes |
| 3. Transaction Validation | Nodes verify the transaction | Nodes check rules like balance, signatures, and permissions |
| 4. Block Creation | Verified transactions are grouped | Valid transactions are bundled into a new “block” |
| 5. Consensus Mechanism | Network agrees on validity | Consensus methods (PoW, PoS, etc.) confirm which block is valid |
| 6. Block Hashing | Block gets a unique cryptographic hash | The block is encrypted with a hash linked to the previous block |
| 7. Block Added to Chain | Block becomes part of the blockchain | The new block is permanently added, forming a chain of blocks |
| 8. Network Update | Ledger is synchronized | All nodes update their copy of the blockchain |
| 9. Transaction Completion | Transaction is finalized | The transaction becomes immutable and publicly verifiable |
Blockchain Workflow at a Glance
| Stage | Key Component | Purpose |
| Input | User / Wallet | Initiates the transaction |
| Verification | Nodes | Ensure transaction validity |
| Security | Cryptography | Protects data integrity |
| Agreement | Consensus Algorithm | Prevents fraud and double spending |
| Storage | Distributed Ledger | Stores immutable records |
Popular Consensus Mechanisms (Quick Comparison)
| Mechanism | Used By | How It Works |
| Proof of Work (PoW) | Bitcoin | Miners solve complex puzzles |
| Proof of Stake (PoS) | Ethereum | Validators stake coins |
| Delegated PoS (DPoS) | EOS | Token holders vote for validators |
| Proof of Authority (PoA) | Private blockchains | Trusted validators approve blocks |
Why This Process Matters
| Feature | Benefit |
| Decentralization | No single point of control |
| Transparency | Anyone can verify transactions |
| Immutability | Data cannot be altered |
| Security | Cryptography prevents tampering |
| Trustless System | No intermediaries required |
Types of Blockchain: Public, Private & Consortium
| Type of Blockchain | Public Blockchain | Private Blockchain | Consortium Blockchain |
Definition |
Permissionless network open to anyone globally. | Permissioned network controlled by a single organization. | Permissioned network run by a group of participating organizations. |
Access |
Open to all, no special permissions required. | Restricted to authorized participants only. | Limited to pre-approved member entities. |
Decentralization Level |
High (fully decentralized). | Low (centralized control). | Medium (shared governance). |
Examples |
Bitcoin, Ethereum, Hedera (a hybrid example). | Hyperledger Fabric, R3 Corda, private Ripple deployments. | Quorum; Canton Network (financial institutions consortium). |
Typical Use Cases |
Public cryptocurrencies, decentralized apps (DeFi), public records. | Enterprise supply chain, internal data sharing, private finances. | Inter-bank settlement, multi-company supply chains, regulated consortiums. |
Consensus Mechanisms |
PoW, PoS, other permissionless protocols. | PoA, PBFT, Raft (less energy-intensive). | PBFT, PoA, DPoS or customized protocols. |
Transaction Speed & Scalability |
Lower speed (e.g., Bitcoin ~7 TPS); scalability solutions evolving. | Higher speed & throughput (fewer nodes). | Moderate to high speed; performance depends on number of members. |
Privacy & Transparency |
Transactions publicly visible. | High privacy within the organization. | Privacy among members; selective transparency. |
Security Review / Community Feedback |
Very secure due to broad decentralization and many validators, but can be slower and costlier (e.g., high gas fees). | Efficient and private but centralized trust can be a vulnerability (private governance, collusion). | Balanced security; shared governance reduces single-point risk, but less transparent than public. |
Typical Costs |
Public: Transaction fees (gas), no infrastructure costs for users; decentralized networks often have higher operational energy use and unpredictable transaction costs. | Private: Costs tied to infrastructure (servers, maintenance, security) and development — no per-transaction fees in many cases but significant enterprise setup costs. | Consortium: Shared infrastructure and operating costs among members; lower per-member burden than private, moderate setup cost. |
Development & Maintenance Costs |
Typically lower for participants (no need to run nodes) but high transaction costs during use due to fees. | High initial setup & ongoing administrative costs; infrastructure and governance enforced by organization. | Shared setup costs; moderate maintenance and governance overhead split across organizations. |
Best For |
Open, trustless ecosystems and financial systems with many participants. | Business processes needing confidentiality and fast settlements. | Multi-party business networks requiring controlled collaboration. |

Blockchain’s Advantages for Businesses
Among the most significant advantages that this technology can provide at the business level are:
Increased Speed:
By eliminating a central authority or intermediaries. Information remains made available to all network participants in the exact location. Simplifying this data transmission process allows us to act faster and more agilely in the management of any information that we consult.
Reduced Cost:
Blockchain is a low-cost technology because it reduces the overload process by eliminating intermediaries and allows us to streamline our processes and communications. We can automate process execution due to a more direct relationship between internal systems and devices.
Increased Security And Trust:
A trusted environment will create in which data exchanges will carrie out using encrypted, And encrypted operations, allowing us to preserve data exchanges and ensure the security of all those involved. Furthermore, the decentralization of information ensures its total immutability.
The Blockchain’s Disadvantages
- When compared to centralized databases, it is slow.
- It provides excellent investment funds in terms of exchange costs and time, but the high initial capital costs may impede.
- Efforts required in blockchain system for achieving consensus across network nodes in blockchain.
- Blockchain is just a data structure; world problems will not all be solved by it.
- All cryptocurrencies will always require a mining system, which will consume huge amounts of energy.
- It alludes to a complete shift to a decentralized system that necessitates the recognition of its clients and administrators.
- Blockchain technology is wholly original and does not necessarily live to the hype about it. It links transactions together in blocks. These blocks connect with one another to form a chain. In particular, the order in which blocks connect is important so that the users can have complete faith in this connection. The latest block will reference previous block.
