Blockchains are tamper evident and tamper resistant digital ledgers\nimplemented in a distributed fashion (i.e., without a central repository) and\nusually without a central authority (i.e., a bank, company, or government). At\ntheir basic level, they enable a community of users to record transactions in a\nshared ledger within that community, such that under normal operation of the\nblockchain network no transaction can be changed once published. This document\nprovides a high-level technical overview of blockchain technology. The purpose\nis to help readers understand how blockchain technology works.\n
