Blockchainconcept
• Blockchainisdistributed,independent,opencommonledgermanagementtechniques
• Bitcoinisanapplicationthatusesthiscommonbookasatransactionrecord

블록체인은 분산되고, 독립적이며, 개방된 공통 장부(원장, ledger) 관리 기술
비트코인은 이 공통 장부를 거래기록 용도로 활용한 애플리케이션
블록체인은 해시 → 해시캐시 → 블록체인 → P2P 네크워크 → 거래기록(비트코인)은 비대칭키 암호화로 구성된다.
Hashcash는 Proof of Work 의 아이디어이다.
비대칭키는 개인키와 공개키 두개를 한쌍으로 암호키로 구성

Hash function
• Onewaycalculationiseasy,butreversecalculationisverydifficultformula
• Therestofthefunctiondividedbyacertainprime(modular)
