# Blockchain Technology Overview

## TL;DR

This paper provides a high-level overview of blockchain technology, explaining its core features like tamper resistance, decentralization, and shared ledgers to help readers understand its fundamental workings.

## Contribution

It offers a comprehensive technical summary of blockchain technology, clarifying how it functions without delving into specific implementations or applications.

## Key findings

- Blockchains are tamper-evident and tamper-resistant digital ledgers.
- They operate in a decentralized manner without central authorities.
- They enable secure, unchangeable transaction recording within a community.

## Abstract

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