Zcash utilizes zk-SNARKs technology to provide secure and private transactions.
Regulatory scrutiny remains a challenge, as Zcash faces potential delistings from exchanges due to privacy concerns.
Future developments may include a transition to a proof-of-stake consensus mechanism, enhancing scalability.

What is Zcash (ZEC)?

Zcash is renowned as a privacy-focused cryptocurrency, providing users with the option to maintain anonymity when executing transactions. Launched in 2016, Zcash was built upon Bitcoin’s code but introduces unique features that enhance its privacy offerings. With options for both shielded and transparent transactions, Zcash aims to be both a means of payment and a secure, open-source cryptocurrency accessible to everyone.

Anonymity and Features

Zcash employs “shielded addresses” that utilize a technology known as zk-SNARKs (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) to ensure transaction privacy. This technique allows users to validate transactions without disclosing any sensitive information about the sender, receiver, or transaction amount. While Zcash is based on Bitcoin, its advanced privacy features set it apart.

The History of Zcash

The inception of Zcash traces back to a white paper published in 2013 by cryptographers Matthew Green and Eli Ben-Sasson, who felt that Bitcoin’s privacy capabilities were inadequate. Initially conceptualized as Zerocoin, the project evolved, and Zcash officially launched in October 2016 under the guidance of CEO Zooko Wilcox and the Electric Coin Company (ECC). The ECC drives the development of the Zcash blockchain while being supported by the Zcash Foundation.

Key Features of Zcash

With a total supply capped at 21 million coins, Zcash shares important characteristics with Bitcoin, such as its proof-of-work (PoW) consensus protocol. A distinguishing feature of Zcash is its capability for “shielded addresses,” which offer privacy by preventing transactions from being publicly recorded on the blockchain.

The "Zcash ceremony" marked the blockchain’s inception, necessitating a trusted group to create the master public key and subsequently destroy any related data to prevent future manipulation. However, this process faced criticism for its lack of transparency.

ZK proofs empower a seamless transaction method where users demonstrate the validity of transactions while keeping all identifying details concealed. The innovative zk-SNARKs ensure that transactions remain secure yet private.

How Does Zcash (ZEC) Work?

Transactions on the Zcash network can either involve shielded addresses (z-addresses) or transparent addresses (t-addresses). When two users employ z-addresses, the transaction remains completely anonymous, rendering it invisible to blockchain trackers. Conversely, if transactions involve a mix of z-addresses and t-addresses, their visibility varies, impacting privacy.

Zcash utilizes a mining algorithm called Equihash, which requires computational memory and helps secure its blockchain. Notably, Zcash transactions per second (TPS) range from six to twenty, influenced by the ratio of shielded to transparent transactions. As most exchanges only support transparent transactions, this affects overall anonymity.

Zcash Upgrades and Developments

In 2019, Zcash made strides with the introduction of Halo, a trustless recursive ZK-proof that improved scalability and addressed the issues surrounding the original trusted setup. The Halo 2 source code was publicly released in September 2020. This advancement allows the network to function without the initial trusted setup, thereby minimizing potential manipulation.

The 2022 upgrade moved Zcash to the Halo proving system, enhancing cryptographic integrity while eliminating the need for the original trusted setup. Additional features like Shielded Coinbase and FlyClient were integrated, enabling miner rewards directed to z-addresses and supporting cross-chain interoperability.

The first halving of Zcash occurred in 2020, decreasing block rewards from 6.25 ZEC to 3.125 ZEC and introducing a development fund, followed by plans for future halvings anticipated around November 2024.

How to Buy Zcash

Zcash (ZEC) can be purchased across numerous major cryptocurrency exchanges, decentralized exchanges (DEXs), and peer-to-peer trading platforms. Buyers typically create an account, deposit funds (often via bank transfer), and select a trading pair to place their orders. On DEXs, users link their crypto wallets to swap other cryptocurrencies for ZEC. However, due to regulatory scrutiny, some exchanges might no longer list Zcash.

The Future of Zcash

Despite its innovative features, Zcash faces criticism for potentially facilitating underground transactions, a concern that has gained traction amid regulatory scrutiny. As a result, its status on some exchanges may be at risk, prompting discussions regarding regulatory compliance and wider adoption.

Additionally, Zcash is exploring the shift to a proof-of-stake consensus mechanism, aiming to enhance scalability. While the energy-intensive blockchain continues to evolve, there’s optimism that increasing demand for privacy-focused cryptocurrencies will benefit Zcash in the long run. However, its ability to navigate regulatory challenges and gain acceptance as a traditional cash alternative remains uncertain.
