The ‘blockchain trilemma,’ idea was first coined the ‘scalability trilemma’ by Ethereum founder, Vitalik Buterin. The example in the previous part of how blocks get added to the Bitcoin blockchain explains this system. While their goal—to attain a consensus that a transaction is valid—remains the same, how they get there’s a little different. To obtain every new key, the previous block’s key and knowledge are inputted right into a formula. Once solved, the block is added to the network—and your fee, combined with all different transaction charges in that block, is the miner’s reward. Records saved utilizing traditional ledgers are additionally straightforward to tamper with, which means you possibly can simply edit, take away, or add a record.
