## What it is
The original zcashd full node implementation for Zcash, a privacy-focused cryptocurrency derived from Bitcoin Core that uses zero-knowledge proofs for shielded transactions. The software reached its End-of-Support halt in July 2026 and users are directed to migrate to Zebra, Zakura, and Zallet.

## Use cases
- run a Zcash full node
- mine or validate Zcash blocks
- send and receive shielded Zcash transactions
- operate a privacy-preserving cryptocurrency wallet daemon
- sync the Zcash blockchain locally

## When to choose
- you need to study or maintain legacy zcashd code
- you are running a historical or archival node for research

## When to avoid
- you want to run a live Zcash node today - use Zebra instead
- you need a supported full node wallet - use Zallet
- you are starting a new project involving Zcash
