…The solutions proposed are all aimed at tackling these. The blockchain scalability trilemma (scalability, decentralisation, security) might be a tricky problem to solve, but it is not something set in stone. Three directions that blockchains are heading towards in order to boost their scalability include novel consensus mechanisms and both on-chain and off-chain solutions. Introduction Blockchain scalability is arguably the holy grail and bottleneck of the cryptocurrency world. It mainly refers …

…Bitcoin’s decentralised nature and limited supply (capped at 21 million coins) have contributed to its popularity and value. As mentioned above, Bitcoin operates on a decentralised network of computers (nodes) that collectively maintain a public ledger, known as the blockchain, that records all Bitcoin transactions in a chronological order, ensuring transparency, security, and immutability. Each transaction is verified by network participants through a consensus mechanism known as Proof of W…

…This process uses a significant amount of computer processing energy: In fact, Bitcoin uses as much power to operate as some mid-size nations. In 2022, Ethereum moved to the Proof of Stake (PoS) consensus mechanism through The Merge upgrade. In the PoS system, a group of participating validators are randomly chosen to validate transactions, verifying them if they reach a consensus (the process known as ‘staking’). The PoS system is faster and requires less computer processing power than PoW,…

…Bitcoin solves this issue with sound consensus mechanisms, including requiring each node to work independently and having a decentralised public ledger that allows anyone to review transactions. Tampering with the system would require majority control of full nodes (a 51% attack) and precise manipulation of blocks to ensure consistency. A further protection is that Bitcoin has no central authority, relying instead on a distributed network of nodes. For example, when consumers use a credit card…

…Like the generals trying to reach a consensus, these computers, also known as nodes, have the job of achieving consensus on the transactions. In the case of a blockchain, the first to propose a solution to this issue was Bitcoin through the Proof of Work (PoW) consensus mechanism. Other forms of consensus mechanisms include Proof of Stake (PoS), Proof of Burn (PoB), and Proof of Authority (PoA). These mechanisms make a network Byzantine Fault Tolerant (BFT).Key TakeawayThe Byzantine Generals Pr…

…Learn more about what it is, why it’s needed — and challenges The Merge might face. Key Takeaways: The Ethereum Merge (also known as The Merge or Ethereum 2.0) is the transition of the Ethereum blockchain’s consensus mechanism from Proof of Work (PoW) to Proof of Stake (PoS). Proponents of The Merge expect it to reduce energy consumption, increase decentralisation, and set the stage for future upgrades that may improve scalability, increase transaction speeds, and lower gas fees.

…As a large part of the global population remains unbanked — with no access to financial services or ability to qualify for bank accounts — Bitcoin is capable of providing financial inclusivity, as anyone with an internet connection can, in principle, access and use Bitcoin, regardless of their location.How to Use Bitcoin (BTC) | Crypto.comPopular ways to use Bitcoin and what you can buy with BTC.How Much Energy Does Bitcoin Consume? | Crypto.comHere’s how energy-intensive Bitcoin’s Proof…

…It is a smart contract platform based on the Ethereum Virtual Machine (EVM) model, but is connected to the Bitcoin blockchain through a sidechain. The Rootstock blockchain uses the Proof of Work (PoW) consensus mechanism, and blocks are mined through merged mining, a process where miners can simultaneously mine both Bitcoin and Rootstock while using the same hashing algorithm and sharing the same computational power. Rootstock features a ~30-second block confirmation time and throughput of aroun…
