…Proof of Burn (PoB) A succinct definition of Proof of Burn (PoB) Proof of Burn (PoB)Level UpNEWIndividualsBusinessesDevelopersDiscoverCompanyGLOSSARYPROOF OF BURN (POB)Copy linkShare on TwitterShare on FacebookShare on LinkedinProof of Burn (PoB)Proof of Burn (PoB) is a consensus mechanism that uses less energy consumption than Proof of Work (PoW). The concept behind PoB requires miners to ‘burn’ a portion of their digital currencies for the chance to mine a new block.In PoB, miners send tok…

…Unlike Proof of Work (PoW) blockchains like Bitcoin, which consume substantial energy for mining, Cardano was one of the first cryptocurrencies to employ a Proof of Stake (PoS) consensus mechanism, which significantly reduces energy consumption by eliminating the need for resource-intensive mining computations like with PoW. Nowadays, a large number of other blockchains also rely on PoS or other environmentally friendly consensus mechanisms, but the green image has stuck to Cardano as a pionee…

…On the other hand, concerns about the energy consumption of Bitcoin mining or potential vulnerabilities in its protocol can cause prices to fall. 5. Market Manipulation Due to the relatively low market capitalisation compared to traditional assets, Bitcoin is more susceptible to market manipulation. Large players, often referred to as ‘whales’, can influence the market by making significant trades that cause price fluctuations. Additionally, the presence of unregulated exchanges increases th…

…Ethereum transitioned from a proof-of-work (PoW) consensus mechanism to Proof of Stake (PoS) with ‘The Merge’ in 2022, significantly reducing energy consumption and introducing staking for network security. Its native cryptocurrency, Ether (ETH), is used for transaction fees (gas fees) and as a form of value exchange within the ecosystem. Ethereum supports thousands of tokens and applications across decentralised finance (DeFi), non-fungible tokens (NFTs), and more. Despite scalability chall…

…This change cut energy consumption by over 99%, and allowed holders to stake their ETH, thus helping secure the network while earning rewards. Ethereum operates its own Layer 1 blockchain, but Layer 2 solutions exist, for example Arbitrum and Optimism. These help scale the network by reducing fees and boosting the speed of transactions. Unlike Bitcoin with its fixed supply, Ethereum adjusts the volume of assets in circulation dynamically, burning a portion of transaction fees to help manage inf…

…This process ensures that the blockchain can operate efficiently and securely without the high energy consumption associated with Proof of Work (PoW) mining.In PoS systems, validators are chosen based on the number of tokens they hold and are willing to stake as collateral. They are rewarded with newly minted tokens after validating transactions and creating new blocks, which incentivises participants to help maintain the security and integrity of the blockchain.Key Takeaway‘Minting’ is the …
…Since hashpower reflects the computational work performed, it directly correlates with energy consumption, raising discussions about the environmental impact of PoW mining.Key TakeawayHashpower, also known as hashrate, is a critical metric that represents the total computational power used to solve cryptographic puzzles necessary for mining, processing, and validating transactions.
