Zk-Snarks stands for “Zero-Knowledge Succinct Non-Interactive Argument of Knowledge”. To understand its application, it is important to know how a smart contract works. A smart contract is basically an escrow of funds which gets activated once a particular function is done.
How is Zcash produced?
After that, I will explain ZCash’s technology in a really simple way, and its potential to either rise or fall in value over time. Ethereum is now moving from using a proof-of-work (PoW) mechanism to implementing a proof-of-stake (PoS) protocol. A miner uses their computer in order to solve complicated equations. Once the equation is solved, a new block is added to the chain and the miner is rewarded with ZEC.

Not only this but once you know the wallet address, you can then view every single transaction that it has sent or received in the past. To validate transactions on the blockchain, miners use their computing power that helps to solve the puzzle (or equation). Once it has been solved, the transaction is then confirmed in the block. To thank miners for solving the puzzle, they are rewarded with the coin native to the blockchain, which in this case is ZCash. Like other types of money, you’ll need a wallet to access your cryptocurrency, including Zcash. A crypto wallet stores the encryption keys required to access your coins.

This was the subject of some controversy within the crypto community. Some accused the coin of being too centralized, while others defended Wilcox-O’Hearn https://www.tokenexus.com/ and praised his transparency. Zcash actually originated from a different digital currency, though one that remained conceptual, called Zerocoin.
- With a brokerage, however, there is no “other person” – you come and exchange your crypto coins or fiat money with the platform in question, without the interference of any third party.
- However, overall, ZCash has performed really well since it was created in 2016 and has established itself as a top 50 cryptocurrency.
- It also enables support for light-client use cases alongside initiatives for developing cross-chain interoperability.
- Between 2016 and 2018, Zcash released a series of upgrades called the “Sprout Series” with two core protocol upgrades, i.e., Overwinter and Sapling.
- In Bitcoin’s privacy model, a user’s transactions are publicly viewable, but their identity is not.
Zcash allows for fully shielded transactions, meaning the sender, recipient, and amount are encrypted. This feature is quite a deviation from the transparency that is a central part of many other cryptocurrencies. Zcash differs from other cryptocurrencies because of its shielded transactions, allowing individuals to maintain complete privacy. Zcash is also decentralized across a wide network, making it more secure and accessible.
Between 2016 and 2018, Zcash released a series of upgrades called the “Sprout Series” with two core protocol upgrades, i.e., Overwinter and Sapling.

Unlike most of the other coins though, Zcash wasn’t pre-mined and nor is it ICO funded. Basically, the function C takes in 2 values as input, a public hash value “x” and the secret statement that needs to be verified “w”. If the SHA-256 hash value of w equals “x” then the function returns TRUE otherwise it returns FALSE. So, to give you an example, this is how zero knowledge proofs used to work before Fiat and Shamir.

In 1986, Fiat and Shamir invented the Fiat-Shamir heuristic and successfully changed the interactive zero-knowledge proof to non-interactive zero knowledge proof. In Zcash, you have a choice to choose between two kinds of transactions. This prompted a deeper professional interest in the Bitcoin and Blockchain space which he had been dabbling in since 2014 as a miner and trader. Aaron now writes about Blockchain Technologies and does content marketing and business development for CoinStructive, a Bitcoin and Blockchain consulting firm.
This usually isn’t a problem in an open ledger like bitcoin where all the transactions are open for the world to see. However, in Zcash, the privacy stops anyone from checking the state of the coins. A big reason why equihash is being used is to make mining as ASIC unfriendly as possible.
