…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…

…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 …

…The platform continues to refine its ecosystem to make it more accessible and efficient for developers and users alike. Check out Polkadot’s current value and recent price trends. Ecosystem Comparison: SOL vs DOT Solana and Polkadot’s Consensus Mechanisms Solana’s consensus mechanism combines Proof of Stake (PoS) with its signature Proof of History (PoH) to maximise transaction efficiency, where validators vote on whether new blocks contain verified transactions that should be added to the…
