What is a Blockchain

A blockchain is a decentralized networking system wherein database is distributed across multiple nodes through digital transactions. It is a safe and secure medium for transferring digital property from one user to another. What enables a blockchain to manage itself is that no single administrator or centralized authority controls data transactions between clients. Users or participating members within the blockchain are connected with nodes which removes the restrictions of accessing, updating, and sending digital data by a centralized server. The database is shared with all network participants with transparency so that no one can question the legitimacy of transactions.

Integrated with a mixture of different digital technologies, a blockchain with its complexity makes it more reliable for exchanging digital data. But because of its functionality and efficient performance, it guarantees participating members with less uncertainty and more convenience and confidence. These technologies involve a blockchain’s identity, program or platform, and peer-to-peer Networking.

Without a governing body, the database could be vulnerable to specific problems such as cyberattacks, digital theft, hacking, and other cybercrimes. Authenticating your identity and authorizing your activities online are two of the essential elements as security and preventive measures. Since a blockchain does not have a governing body, the capacity to authenticate your identity and authorize your digital transactions are distributed across its network and delegated to peer nodes or network participants. This is called peer-to-peer networking. You also possess private key cryptography which already authenticates your identity while still protecting your private information from the blockchain network. A blockchain’s protocol is designed to record transaction data history for recordkeeping and security purposes

Today, blockchain’s reputation is increasingly reaching dozens of people and businesses. It’s innovations of cryptographic keys and shared ledgers, and blockchain networks are gaining more momentum and power in the digital world.
