…Each node needs to agree on a preconceived set of rules (called ‘consensus mechanisms‘) in order to participate in the blockchain network and reach an agreement. Using these mechanisms, we can solve the Byzantine Generals Problem. Learn more about consensus on blockchain: How to Agree: Different Types of Consensus for Blockchain. Centralised, Decentralised, and Distributed Systems While a centralised system is easy to understand, differentiating a decentralised system from a distributed one …

…In contrast, for crypto staking, the cryptocurrency is locked up in order to participate in running the blockchain and maintaining its security. How Does Staking Work? In order to understand how staking works, let’s first look at what Proof of Stake (PoS) blockchains are. Consensus mechanisms: A blockchain is essentially a digital ledger used to record transactions. These transactions need to be verified and agreed upon (reach a consensus) by many different computers (called validators in Po…

…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…

…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 …
