Essential Blockchain Fundamentals Every Inexperienced Investor Needs to Grasp Prior to Engaging in Investment
In the ever-evolving world of cryptocurrency, understanding the fundamental workings of blockchain technology is crucial for both investors and enthusiasts alike. This article will delve into the various consensus mechanisms that underpin blockchain networks, providing a foundation for navigating the complex landscape of digital assets.
Before diving into the specifics, it is essential to emphasise the importance of investing in knowledge before investing in any crypto project or buying crypto. To avoid scams and make informed decisions, it is recommended to read, watch, ask questions, and do thorough research.
The main consensus mechanisms used in blockchain technology include:
- Proof of Work (PoW) PoW is a mechanism where miners compete to solve complex computational puzzles, with the first to solve it proposing the next block and earning a reward. Bitcoin uses PoW to maintain network integrity, making it computationally expensive to alter past transactions, thereby deterring malicious actors.
- Proof of Stake (PoS) In PoS, validators are selected to propose and validate blocks based on the amount of cryptocurrency they "stake" as collateral. This method reduces energy consumption compared to PoW and incentivises honest behaviour since staked tokens can be forfeited if validators act maliciously. Ethereum 2.0 uses PoS to improve scalability and security.
- Delegated Proof of Stake (DPoS) DPoS involves token holders electing a small group of delegates who validate transactions and maintain the blockchain. This increases transaction speed and scalability while maintaining a level of decentralization. Platforms like EOS and Tron employ DPoS.
- Practical Byzantine Fault Tolerance (PBFT) PBFT is designed for permissioned blockchains and allows nodes to reach consensus even if up to one-third are faulty or malicious. Nodes exchange messages to agree on the blockchain state, providing high fault tolerance and reliability, often used in private or enterprise settings like Hyperledger Fabric.
- Proof of Authority (PoA) PoA involves a small set of trusted validators pre-approved to validate transactions and create blocks. This consensus is faster but less decentralized, suitable for private blockchains where participants are known and trusted.
These consensus mechanisms contribute to blockchain security and resilience by ensuring agreement among distributed nodes, deterring malicious activity, handling faulty or malicious nodes gracefully, maintaining immutability, and enabling decentralization.
In summary, different consensus mechanisms provide alternative trade-offs between security, decentralization, energy efficiency, and transaction speed, tailored for varying blockchain environments such as public, private, or consortium networks.
Aside from finance, blockchain technology is being utilised in various industries, including supply chains, digital identity, gaming, voting, and art & music.

In the crypto world, coins are native to their own blockchain (e.g., BTC on Bitcoin, ETH on Ethereum), while tokens are built on top of blockchains (e.g., USDC, SHIB, or any NFT). Smart contracts are bits of code written on the blockchain that execute when conditions are met, and can be used for tasks such as transferring NFTs, recording votes in DAOs, and enforcing terms of crypto loans.
Lastly, it's essential to remember that blockchain is not magic but tech that can be complex, yet understandable once broken down. Having a solid foundation in blockchain basics will help in spotting opportunities and staying informed.
