states, which we may map to the numbers 0 and 1. Larger integer numbers can be represented by a sequence of multiple bits. The Morse code was an early application used to transmit messages encoded in optimization of computer programs. WHAT IS A COMPUTER PROGRAM? A computer program is essentially a sequence of numbers that are meaningful to a computer CPU. The CPU recognizes these numbers as instructions known as the assembly language. In that language, for example, the character sequence "add A0, $8" may map directly to a sequence of numbers which instructs the CPU to add the constant integer number 8

discussion to another time! Upon receipt of a block, a peer will process each transaction in the sequence in which it appears in the block. For every transaction, each peer will verify that the transaction The blockchain is structured as sequential log of interlinked blocks, where each block contains a sequence of transactions, each transaction representing a query or update to the world state. The exact mechanism the ordering service. Its job is to arrange batches of submitted transactions into a well-defined sequence and package them into blocks. These blocks will become the blocks of the blockchain! The number
