Zcash Gives You a Privacy Switch Most Holders Never Flip

Key Takeaways
  • Zcash started offering fully private transactions in 2016. However, the privacy is optional, and for most of the network's life, the majority of ZEC has moved on the public side instead.
  • Zcash uses two address systems side by side. Transparent addresses behave like Bitcoin addresses. Shielded addresses hide the sender, receiver, and amount.
  • Coins sitting on an exchange get none of this protection. The platform sees everything, and KYC has already tied your name to it.
  • Moving coins from transparent to shielded takes one transaction. Undoing that protection takes just one careless round trip back to the same exchange.
  • Shielding changes who can see your trades. It changes nothing about the flat 30% VDA tax under Section 115BBH or the 1% TDS under Section 194S.

In 2016, Zcash was launched with a unique feature of shielding transaction details. However, the public ledger is still the more utilized ledger. The public ledger shows what the users of the network want to disclose. Price charts do not illustrate the gaps between what a blockchain is capable of and what is utilized by the users of the blockchain.

What does the Zero Knowledge Proof Actually Do?

Zcash (ZEC) is a cryptocurrency similar to Bitcoin, but with additional security features that enable privacy and anonymity. The ZEC blockchain uses zero-knowledge proofs to provide a mathematical way of proving ownership of a particular amount of coins without disclosing other information. The proof is accepted by the blockchain, and the transaction is finalised. Zero-knowledge proofs keep all information involved in the transaction private.

Zero-knowledge proofs keep the information involved in the transaction private and have numerous off-chain use cases. For example, using zero-knowledge proofs, a person can be mathematically proven to be above the minimum age required for entry to a bar without disclosing their name, address, or date of birth to the door person.

Four Methods of Sending ZEC

Zcash supports transparency, and therefore enables users to choose between private or public transactions. Transparent addresses start with t1 or t3 and work similarly to transactions on the Bitcoin blockchain, while private transactions are protected by zero-knowledge proofs. Private transactions can be further divided into more private transactions based on the amount of information disclosed.

The chart below counts the same thing numerically. Every transaction carries three fields that can be exposed: sender, receiver, and amount, and the bars show how many stay public in each case.

On-chain and Off-chain Transactions are separate Concerns.

Generally, on-chain transactions involve the ZEC blockchain, and off-chain transactions do not. Off-chain transactions include a centralised exchange moving ZEC between two of its customers. In this case, the exchange doesn't involve the ZEC blockchain.

Sounds private, but the exchange ultimately controls the coins and can access all info about the transactions and users from KYC. There is no cryptographic protection for you until you possess the coins and use a shielded address.

How Are Coins Transparent?

There are two main behavioral factors that impact shielding: the time of the transaction and the address that the coins are transmitted to.

Because of the behavioral factors at play, it is possible for coins to be transparent even though a shielding transaction was processed. It is also possible for coins to be transmitted to a shielded address even though there was no shielding transaction. Because of this, determining if coins are transparent or shielded can be complicated.

Which Exchanges Support Shielding?

Not all exchanges support shielding. Some do not allow deposits from shielded addresses. Make sure to check the rules of an exchange before sending shielded coins. Only a handful of wallets support shielded addresses to begin with, among them Zashi, Ywallet, Zingo, and Nighthawk.

What about the Company behind Zcash?

The Electric Coin Company, founded by Zooko Wilcox, created and launched the Zcash blockchain and built the Zcash wallet, Zashi. The Zcash Foundation, a different company, created a second implementation of a Zcash node, Zebra. Other companies and developers receive grants to work on Zcash and Shielded Transactions from Zcash Community Grants. Shielded Labs is also working on the planned move from mining to staking. The community decides how the block rewards are allocated, and the most recent negotiation occurred at the NU6 upgrade in November 2024.

Two updates impact Indian users the most. The first, known as NU5, launched in May 2022. This update introduced Zcash's first shielded transaction pool, known as the Orchard. This update also unified users' shielded and transparent addresses. This means users no longer have to decide which type of address they want to use. NU6, released in November 2024, implemented the second halving and adjustments to the current funding system.

Impact on Indian Users

Shielding has no effect on your income tax liability. The Indian government has enacted legislation, which is a part of the Income Tax Act, to impose a flat 30% income tax on profits derived from the sale of Virtual Digital Assets (VDAs) under Section 115BBH, and to provide that exchanges are obligated to withhold a 1% TDS on the sale of VDAs under Section 194S. Furthermore, the loss from the sale of a VDA cannot be set off against the gains from the sale of another VDA. It is also worth mentioning that, as of the date of this writing, cryptocurrency exchanges operating in India are required to register with FIU-IND as reporting entities under PMLA. This means that, regardless of the transactions on a given exchange, the initial and final points of the cryptocurrency transactions are fully known and identified.

From a tax compliance perspective, a "viewing key" can be issued to a chartered accountant, auditor, or tax authority to give them the ability to view a holder's transactions without granting any ability to spend. Confidential is not the same as hidden, and neither is the same as exempt.

One risk worth pointing out is that several jurisdictions and exchanges have delisted or restricted privacy coins on anti-money laundering grounds, including forced delistings in Japan and South Korea. That pressure remains a live regulatory risk for ZEC specifically, separate from ordinary price volatility.

Frequently Asked Questions

Is holding or trading ZEC legal in India?

Yes. Crypto is neither banned nor licensed in India. It sits in a regulatory grey zone, unregulated as a currency or security but taxed as a VDA under Section 115BBH, and taxation itself implies the activity is legally recognised. Privacy features do not change that status. What can change is access, since an individual exchange may choose not to list a privacy coin.

Does using a shielded address help me avoid the 30% tax or the 1% TDS?

No. The tax liability attaches to the gain, not to how visible the transaction was, and TDS is deducted by the exchange at the point of the trade regardless of which address type is involved. Treating shielding as a way to sidestep reporting is a compliance risk, not a tax strategy. The viewing key exists precisely so a holder can disclose their own transactions when required.

If I buy ZEC on an exchange, are my coins already private?

No. Coins held in an exchange account are recorded on that platform’s internal ledger, not in the shielded pool, and the exchange holds the keys along with your KYC identity. Privacy begins only after you withdraw to a wallet you control and send the coins into a shielded address yourself.
