Ledger Series, Part I: The double entry Model
Most financial systems start the same way. You re building a wallet, a user has $100, they send $30 to a friend, so you write balance = balance - 30 on one row and balance = balance + 30 on the other.

Understanding The Modular Blockchain Infrastructure
First generation blockchains like Bitcoin, Ethereum and Solana are saddled to the tasks of carrying out consensus, settlement, execution and data availability on the same layer hence they have been termed monolithic blockchains. By design, monolithic blockchains can’t effectively carry out all these tasks and this leads to the rise of the blockchain trilemma.
