1. Introduction
Via Coin is an open source digital currency created on the Bitcoin protocol in 2014. It supports embedded consensus and supports extension of OP_RETURN 120 bytes. Via coin features Scrypt merged mining, also known as Auxiliary Proof-Of-Work (often abbreviated as AuxPoW), which is 25 times faster than Bitcoin (24-second block time).
Via mining rewards are halved every 6 months (current block rewards are 0.3125 coins per block), with a total supply of 23,176,392, keeping inflation and mining rewards relatively low . In order to maintain mining interest, merged mining (AuxPoW) has been implemented, in which the largest share of hashing originates from the Litecoin network. Via coins are currently mined by the world's largest mining pool, F2Pool, thus maintaining a very high hash rate.
Other features of Via coin include the Dark Gravity Wave mining difficulty adjustment algorithm (Dark Gravity Wave), which aims to solve the defects in the Kimotos Gravity Well, version bit (BIP9), and allows up to 29 parallel soft The fork function is executed in the codebase, as well as Segregated Witness (Segwit) and Lightning Network.
2. Project introduction
ViaCoin (VIA for short) plans to develop a protocol called "ClearingHouse" to build VIA blocks and allow applications to be built on it. Its total amounted to 92 million. The initial 10 million will only be distributed through pre-sale, and no pre-mined coins will be distributed to developers. The remaining 82 million VIA will be distributed as block rewards over the next 24 years. Vircoin is currently approaching block 7000 with a block confirmation time of 24 seconds. The 0 reward mining period will continue until sometime tomorrow morning. After the block reward starts, every 10,000 blocks, the reward will decrease.
VIA coin has the Styx function, which is characterized by high anonymity. It adopts zero knowledge contingent payment proof, which allows users to pay anonymously, which is safe and fast, and does not leave any money in the process. Download any traceable information so that holders of via coins can safely protect their assets, minus the risk of being stolen by others. Via has an atomic mixing function, which uses the smart contract in the Via Script function to execute the atomic payment protocol, which allows us to exchange a Via coin for a hash or an elliptic curve cryptographic calculation. And the script function of via coin combines the encryption calculation outside the blockchain and uses the RSA encryption algorithm, random oracle model (ROM) and elliptic curve cryptography.
Vircoin was created to allow decentralized services such as trading platforms, asset tracking, and voting to be provided on the blockchain. The goals of Velcoin are similar to that of Contractcoin, which seeks to solve the problems faced by previous projects by moving decentralized services from the Bitcoin blockchain to a blockchain that explicitly supports such development.
3.Review
Viacoin is an open source cryptocurrency project based on the Bitcoin blockchain. Launched publicly on the cryptocurrency market in mid-2014, Viacoin integrates decentralized asset trading onto the blockchain at speeds never before seen in cryptocurrencies.
This Scrypt-based proof-of-work coin was created to try and contrast Bitcoin's structural issues, primarily because the currency's transition from a digital currency to a fixed store of value like gold hinders the Congested blockchain latency for microtransactions.
