Blockchain technology is a relatively new concept initially developed to support Bitcoin. However, the technology's popularity has grown, and more people are discovering that blockchain technology can be used for purposes other than cryptocurrency.

FREMONT, CA: Blockchain is a distributed ledger technology (DLT) intended to foster an environment of trust and confidence. Blockchain is a distributed ledger technology that is replicated and distributed across an entire network of computer systems. It enables access to information for all designated nodes or members, allowing them to record, share, and view encrypted transactional data on their blockchain.

Blockchain technology collects and stores data in groups, also known as "blocks," and each block can contain a finite amount of data. When a block reaches its capacity, it is chained to the entire previous block, forming a data chain, thus earning the clever name "blockchain."

Blockchain security is a comprehensive risk management system for blockchain networks, incorporating assurance services, cybersecurity frameworks, and industry best practices to mitigate fraud and cyber-attack risks.

Because blockchain technology is based on consensus, cryptography, and decentralization principles, its data structures are inherently secure. Each new block of information is inextricably linked to all previous blocks in a way that makes tampering nearly impossible. Additionally, a consensus mechanism (authorized users) validates and agrees on all transactions within a block, ensuring that each transaction is true and accurate. As a result, there is no single point of failure and no way for a user to modify transaction records.

However, blockchain security goes beyond the technology's inherent security features. This is how.

What Are the Different Kinds of Blockchain?

Private Blockchains: Invitations to private blockchain networks are required. Users must be validated either by the network's central administrator or starter or by the network's administrator using a rule set. Typically, businesses that utilize private blockchains establish a permissioned network. Permissioned networks place restrictions on who can join and what types of transactions they can initiate. In either case, participants must be invited or granted permission to join. Private blockchains are frequently used in internal, business-secure environments to manage access, authentication, and record-keeping tasks. Typically, transaction data is kept private.

Public Blockchains: Public blockchains are designed with participation and transparency in mind. The consensus mechanism is "decentralized," which means that anyone can validate network transactions, and the software code is open-source and freely available (e.g., Bitcoin and Ethereum).

The primary characteristic of public blockchain networks is decentralization via crypto-economics, which is used to ensure network cooperation. This means that the network lacks a political control point in public blockchains, and the software system's architecture lacks a central point of failure.

The consensus algorithm's design, network governance, ownership of cryptographic "private keys," and economic incentives determine how decentralized a blockchain is. Consider the concept of "data mining," which rewards users for validating transactions. This incentive incentivizes people to join the network and assist in validating transactions.

Governance considerations include who develops the software code, who is allowed to participate in the consensus mechanism, and who can participate in the communal governance activities that keep the network running. Consensus mechanisms for public blockchains are primarily "Proof-of-Work" (PoW) or "Proof-of-Stake" (PoS) (PoS).

However, anyone can join and validate transactions on a public blockchain, a significant distinction between public and private blockchains.
