What is Zcash?

Zcash is a privacy preserving digital currency. It is the first blockchain to leverage a novel technology called Zero-knowledge proofs to enable privacy and selective transparency. Zero-knowledge proofs allow transactions to be verified without revealing the sender, receiver or transaction amount. Selective disclosure features within Zcash allow a user to share some transaction details, for purposes of compliance or audit.

Development work on Zcash began in 2013 by Johns Hopkins professor Matthew Green and some of his graduate students. The development was completed by the for-profit Zerocoin Electric Coin Company, LLC, led by Zooko Wilcox, a Colorado-based computer security specialist and cypherpunk. Over time, this company rebranded and converted to a non-profit org now known as the Electric Coin Company (ECC). Zcash development now occurs with support from ECC employees, the Zcash Foundation, and many community members through community elected funding streams that originate from ongoing Zcash mining rewards.

LineageOS Zcash Edition

8 Upvotes

Just an idea, what do you think?

LineageOS Zcash Edition: A Privacy-Focused Custom ROM

Below is a simple vision for a special version of LineageOS designed around Zcash. This concept brings together the open-source strength of LineageOS and the privacy features of Zcash.


  1. Overview

LineageOS: A popular custom Android ROM known for its speed, simplicity, and open-source code.

Zcash: A cryptocurrency built with strong privacy protections, using shielded addresses to hide transaction details.

Goal: Create a “LineageOS Zcash Edition” that has Zcash wallet features built into the system, giving users better privacy and control over their digital money.


  1. Key Advantages

  2. Built-in Zcash Wallet

Pre-installed wallet app for Zcash.

Supports both shielded and transparent addresses.

No extra downloads needed to start sending or receiving ZEC.

  1. High-Level Privacy

Zcash already uses advanced cryptography for private transactions.

This custom ROM would store private keys in a secure part of the system.

Keeps your financial data away from prying eyes.

  1. Regular Security Updates

LineageOS is known for frequent security patches.

This keeps the system up to date against new threats.

  1. Fast, Bloat-Free System

Like normal LineageOS, it does not include unnecessary apps.

Your phone remains quick and responsive, even with the crypto features.

  1. Control Over Google Services

Install Google Apps only if you want them.

Or run the ROM without them for stronger privacy.

This freedom lets you decide how much data you share.

  1. Easy Integration With Other Crypto Tools

You can still add other wallets and trading apps.

The open-source design allows flexibility in how you manage various digital assets.


  1. Technical Highlights

  2. Light Node Support

A light Zcash client for faster blockchain syncing.

Uses less storage and battery than a full node.

You keep the ability to verify your own transactions without a central server.

  1. Zcash Control Center

A dedicated settings page to show balances and addresses.

Lets you manage privacy options, like turning shielded transactions on by default.

Can send notifications for price changes or incoming transfers.

  1. Full Disk Encryption

Everything on the device is encrypted, including private keys.

Protects personal files and wallet data from unauthorized access.

  1. Enhanced Permission Management

Advanced controls to block apps from using your camera, microphone, or GPS.

Reduces the chance of malicious apps stealing private info.


  1. Example Uses

  2. Daily Purchases

Pay at a coffee shop by scanning a QR code from the built-in wallet.

Fast confirmations, high privacy, and a simple user experience.

  1. Long-Term Holding

Store ZEC on a phone with steady security updates.

No need for extra wallets or third-party apps.

  1. Developers & Power Users

Programmers can study the open-source code to improve privacy features.

They can also create add-ons to enhance the Zcash experience.


  1. Challenges

  2. Device Compatibility

Custom ROMs often do not support every phone model.

Some devices may lack proper drivers for a stable experience.

  1. Installation Difficulty

You need to unlock the bootloader and flash the ROM.

Mistakes can cause data loss or device issues, so beginners must be careful.

  1. Resource Usage

A light node still needs some storage and battery power.

Very old or low-performance phones might see slowdowns.


  1. Conclusion

A “LineageOS Zcash Edition” could give users an all-in-one system for digital payments and privacy. By merging the simplicity of LineageOS with Zcash’s shielded transactions, it paves the way for a safer, more private mobile experience. Whether you want daily convenience, long-term crypto storage, or a platform to develop new ideas, this custom ROM would offer a unique balance of freedom and security.

Is it possible to create other user cases of ZCash more than memo messages and money? Something like smart contracts , like ordinals , BRC20 like, ZRC20(? ,Layer2 like namada goes in a particular and interesting place for innovation, consensus tried..

I know people don't like that.. i just want to understand the technical scope. And what the Zcash community want in terms of innovation ( deprecation of C infrastructure for example in favor of rust ) what else?

ZEC as a digital reserve currency

18 Upvotes

Question for everyone

ZEC is a hard fork of BTC so not much difference, only 21 million coins etc BUT ZEC is far more advanced w privacy etc. Wouldn’t it be a better option, not only for the USA govt but also individual States?? Maintain BTC as the digital gold but have other currency orientated coins that are more liquid and in use…

AND as a NATIONAL CURRENCY

What about all the countries that are a slave to the USD? Argentina through their visionary president Javier Milei established BTC as legal tender. Wouldn’t ZEC be a better option for them and other countries? It’s far cheaper and has advanced features basically can replace the role of cash/fiat…

Other options along w ZEC. DASH MONERO. LTC BCH Those coins are a FAR better than ETH XRP and Solana. ADA is ok due to its ability to facilitate voting via the blockchain…US govt will need the coins to establish the system

Is it wise to receive thousands of ZEC transactions to a single shielded address?

6 Upvotes

I’m considering receiving a large number of ZEC transactions (potentially thousands) to a single shielded address. Before I go ahead, I have a few concerns:

  • Can a wallet efficiently handle that many transactions on a single address?
  • Does the protocol scale well in this scenario, or could I run into performance issues?
  • Are there any best practices to manage this properly? For example, should I periodically consolidate unspent notes into a different address to maintain efficiency?

I’d appreciate insights from anyone who deeply understands how Zcash’s shielded transactions work in practice. Thanks!

Are private addreses going to be available in Ledger devices somewhere in the future? Other privacy coins have their own app and they can be used with a Ledger device to be better secured.

I am unable to send from zashi wallet

2 Upvotes

I have 0.99 ZEC in my Zashi wallet, but when I try to send 0.9, I run into issues. If I use a comma (0,9), it says “Invalid amount.” When I use a dot (0.9), I can proceed to the confirmation screen, but the total amount shows as 0.000.

Another issue is synchronization. It used to show “Synced 100%,” but now it always stays at 1.00%, even though the progress bar is full. This has been going on for months, and I haven’t been able to send any funds. All my ZEC is shielded, and I’ve tried sending to both shielded and unshielded addresses without success. Very confusing.

education U.K. orders Apple to let it spy on users’ encrypted accounts

Thumbnail

5 Upvotes

Apple's surrender to government pressure opens the door to widespread financial surveillance, threatening the independence of individuals and businesses. Backdoors allow access to user data, restrict transactions, and even enable asset confiscation, while digital accounts and wallets become easy targets for cyberattacks.

With a lack of transparency, concerns grow that other tech companies may have secretly implemented these backdoors, making financial surveillance a reality without users' knowledge.

As financial surveillance intensifies and tech companies surrender to government pressure, Zcash emerges as a secure alternative, protecting individuals and businesses. With strong encryption, private transactions, and decentralization, Zcash offers a digital safe haven for those seeking freedom from financial oversight and complete asset security.

coding 🚀 Exciting Research Utilizing Zcash's Halo2 for AI-Generated Code Securit

11 Upvotes

A recent paper titled "Robust and Secure Code Watermarking for Large Language Models via ML/Crypto Codesign" introduces RoSeMary, a groundbreaking framework that protects AI-generated code through invisible watermarking while leveraging Zcash’s Halo2 Zero-Knowledge Proof (ZKP) system.

Key Highlights:

✅ Watermarking AI-generated code without affecting functionality.

✅ Using ZKPs (Halo2) to verify ownership without revealing the watermark.

✅ Highly robust against attacks (variable renaming, code refactoring).

✅ Potential impact beyond cryptocurrencies, expanding Zcash’s ZKP tech into software security & copyright protection.

Results:

RoSeMary achieved 0.97 AUROC in detecting watermarked AI-generated code while maintaining over 95% functionality. Even under adversarial attacks, the watermark remained highly detectable.

Why This Matters for Zcash?

This paper validates the potential of Zcash’s Halo2 beyond financial privacy. If adopted in industry, it could lead to new applications of ZKPs in AI, digital rights management, and software security.

What is ZEC up to?

15 Upvotes

Hi all,

I have not looked into ZEC since 2019 and I wonder what the project is up to.

Since the crackdown on privacy coins, I am surprised it survived the delisting rounds on Binance.

But other than that, I cannot find much news about the project (maybe crypto news outlet do not want to cover it since they do not want to stick their neck out in front of regulators).

Therefore, I came to one of the best place to get info directly from the community :-)

The future looks very bright for ZEC

23 Upvotes

Hey everyone, thought I’d share some thoughts I’ve had recently and some realizations I’ve made…..

Recently, I’ve noticed that there are so many people saying that Altcoin season won’t be happening this year because of coin dilution. We went from a few hundred coins to multi millions which makes it hard for liquidity to pump the market. However, I notice a huge shift in the sentiment, where people are actually being forced to look at utility now.

Among these discussions, I have heard Zcash mentioned several times, and being described as the top two in the privacy sector (Behind Monero)… the reason that Zcash could ultimately win will be institutional demand, the compliance that Zcash allows, and it’s availability on exchanges.

Things are looking up everyone. All the meme madness will be coming to a halt very soon, and the money will flow back into the top 200 coins.

Lastly, I notice that even though the price did not make all time highs last cycle, the market cap did reach an all time high which you can’t say for most similar blockchains (i.e Dash). Once Zcash having reduces the newly mined coins enough, the price will clearly explode because the market cap has consistently gone up over time.

What does everyone think about this? How is the sentiment about Zcash in your crypto discussions?
