Understanding zero knowledge proofs and zk-SNARK.
0 Comments27 Minutes
zk-SNARK (Zero-Knowledge Succinct Non-Interactive Argument of Knowledge) is the protocol of zero knowledge proof. ZCash cryptocurrency will be the one of first opened blockchain projects, which will utilize the implementation of this fascinating algorithm in the mechanics of blockchain. Zero knowledge proofs have huge potential…

Optimal strategy for safe Oracles use in web3
The oracle's business model is to execute off-chain (off-blockchain) queries and return them to the contract in exchange for a fee, which the contract pays by asking oracles for off-chain data.

How to achieve decentralization using Oracles in blockchain?
So how do we create a decentralized oracle? The model is as follows: a contract should ask several oracles to execute the same query, get results from each oracle, and then determine the correct answer on its own based on multiple results (answers from multiple oracles).

How to read non-blockchain data in smart contracts and how Oracle works?
External data to the smart contract (from outside the blockchain) can be provided only, as parameters (arguments) of its call. Oracles are software running outside the blockchain, which listens for "requests" by smart contracts for external data, and then provides this data to the smart contract, by calling the appropriate…
