## What it is
Electrs is an efficient Electrum server re-implementation written in Rust that indexes the entire Bitcoin blockchain using RocksDB. It lets users self-host an Electrum server on hardware comparable to a full node, enabling fast wallet balance and transaction history queries while preserving privacy.

## Use cases
- self-host an Electrum server for my Bitcoin wallet
- index the Bitcoin blockchain for fast balance queries
- run a private Electrum server without leaking my addresses to third parties
- track wallet balances and transaction history in real time via Electrum wallet
- serve Electrum protocol queries from my own full node

## When to choose
- you want a privacy-preserving personal or small-scale (family/friends) Electrum server
- you have a Bitcoin full node and modest extra hardware resources
- you need fast blockchain synchronization and low index storage overhead
- you prefer a resource-efficient Rust implementation over ElectrumX

## When to avoid
- you want to run a large public Electrum server exposed to the internet (use the Blockstream electrs fork instead)
- you need to serve many concurrent users at scale
- you cannot run a Bitcoin full node alongside it

## Facets
- artifact type: application
- maturity: active
- function: search-engine, database, http-server, self-hosted
- domain: blockchain, self-hosted, privacy, databases
- platform: rust, self-hosted, cli
- tags: bitcoin, electrum-server, blockchain-indexer, rocksdb, wallet, full-node, cryptocurrency, linux, macos
