A list of the most common questions about Zcash. For troubleshooting the Zcash client, please see the official troubleshooting guide.
Zcash is a digital currency with fast, confidential transactions and low fees. Privacy is the central feature of Zcash. It pioneered the use of zero-knowledge proofs to encrypt all transactions.
Several wallets are available for instant, mobile, secure and private payments: Wallets
You can buy ZEC on custodial exchanges, DEXs, or centralized swap platforms.
You can also purchase Zcash peer-to-peer or acquire it by mining.
Zcash is fundamentally more private than Bitcoin or Ethereum. It offers fast block times (75 seconds), low fees, and regular upgrades.
Users can choose between Transparent or Shielded transactions. For more information see A Shielded Ecosystem.
The protocol is governed by the Zcash Improvement Proposal (ZIP) process. Anyone can submit a draft ZIP. Drafts are debated by the community and accepted or rejected by the ZIP editors:
Decisions are written into the specification and ratified on-chain when the network adopts them.
First read our guide to block explorers. Then check Zcash Block Explorer.
Transactions expire after approximately 25 minutes (20 blocks) and funds are returned automatically.
Common reasons a transaction may not appear:
Tips to succeed:
Yes. Zcash encrypts sender, amount, and recipient data for shielded transactions.
Zcash does not:

zcashd is retired. Version 6.20.0 shut itself down at block 3417100 on 18 July 2026, and it never supported Ironwood (NU6.3), so there is no later version to upgrade to.
Run the Z3 stack instead. Three programs split the job zcashd used to do alone:
Zakura is an alternative full node. It also runs zcashd on top of itself, which helps if other software still expects the old interface.
Start with the migration guide.
Zallet migrates an existing wallet.dat, so you keep your funds and addresses.
Back up wallet.dat first, then follow the migration guide. Keep that backup until you have confirmed your balance in Zallet.
The Zallet quick reference covers everyday commands once you are across.
Ironwood is network upgrade NU6.3, live on mainnet since block 3,428,143 on 28 July 2026. It adds a shielded pool built on a corrected circuit and seals the older Orchard pool, so anyone can verify that no ZEC was forged.
If you hold shielded funds, they may need to move. Value leaves Orchard only through the turnstile, and wallets handle the move at different times and in different ways. Ask your wallet provider before moving anything by hand.
Read Ironwood for what changed and why.
Zebra is the direct replacement for zcashd and the node the migration guide assumes. Pick it unless you have a reason not to.
Zakura is a second implementation aimed at scale, with faster sync and native block pruning. Pick it if you need those, or if you depend on software that still speaks to zcashd.
Both validate the same chain, so this is an operational choice rather than a consensus one.
See the Zcash Library. It covers the node and wallet software, the shielded pools, and the ZIP numbers that turn up most often.
| Misconception | Correct Answer |
|---|---|
| Is Zcash a centralised coin? | No. A trademark agreement prevents the Zcash Foundation or ECC from acting against community consensus. Governance is proven decentralised (see Messari report). Community polls, ZecHub, and Zcash Foundation A/V Club all enable broad participation. |
| Does Zcash have a backdoor? | No. Neither Zcash nor any cryptographic software we have built contains a backdoor, and never will. |
| Is Zcash controlled by a corporation? | Incorrect. While we partner with companies for research, Zcash remains committed to decentralisation. Multiple autonomous organisations work together toward self-custody and privacy rights. |
| Zcash has limited privacy compared to other privacy coins | No. Monero/Grin-style privacy relies on decoys (which can be defeated). Zcash encrypts all shielded transaction data so every transaction in the pool is indistinguishable. See Not Private Enough?. |
