PIVX stands for Private Instant Verified Transaction. PIVX is an MIT licensed anonymity-based cryptocurrency created out of a fork of DASH. PIVX is an open source blockchain-based Proof of Stake cryptocurrency with Zerocoin protocol implementation for industry leading transaction privacy. PIVX project is focused on advancing its privacy technology to ensure fungibility, improve network scalability and increase real-world utilization to become an effective decentralized online digital currency for everyone. PIVX inherited all the technical features of DASH such as masternodes, instant send and private transfer. It has a block time of 60 seconds and has a fixed reward size per block that uses a custom Seesaw Algorithm that dynamically alters the reward split between masternode and staking nodes. PIVX also utilizes a decentralized network of masternodes that allow feature services, treasury management, and community governance. The project is focused on advancing its privacy technology to ensure fungibility, improving network scalability, and increasing real-world utilization to become a globally-accepted decentralized online digital currency. PIVX is the first cryptocurrency to implement a directly spendable Zerocoin protocol and has also developed and implemented an industry-first Zerocoin-capable Proof of Stake consensus algorithm, called zPoS, that allows complete privacy of the balance and transactions while staking. PIVX “wallet” software closely resembles running your own bank, while basecoin (PIV) for transparent transactions and Zerocoin (zPIV) for completely anonymous, untraceable transactions. PIVX is an advanced privacy-enabled proof-of-stake cryptocurrency using the Zerocoin Protocol, an advanced zero-knowledge-proof privacy protocol for utmost transaction anonymity, and zPoS, a world’s first privacy-enabled Proof of Stake technology all developed by a team of highly experienced developers and cryptographers. Here at PIVX, we wanted to do something innovative, so we brought this cutting-edge technology to life. PIVX is available to be purchased directly with some popular fiat currencies. Here are some exchanges that provide the option to buy PIVX with currencies (USD, EUR etc.) UpBit, Coinroom, LiteBit. The PIVX network allows for 2.6 million PIVX tokens to be minted per year forever, with 90% of the minted coins going to staking wallets and Masternodes (staking is covered in the next section), and 10% going to fund budget proposals voted on by the Masternodes and stakers. This lack of a maximum coin supply makes PIVX function similar to a traditional currency, as inflation is introduced to the system to encourage daily usage and avoid hoarding. The inflation is around 4% per year, but instead of simply devaluing your currency like the Fed does when it prints Dollars, all those minted coins are going directly to holders of PIVX, offsetting the effect of inflation by spreading the profits. PIVX is a promising privacy coin aiming to be an easy-to-use digital cash replacement. There have been a few hiccups surrounding the implementation of the privacy technology, but the community and development team are active, engaged, and optimistic. It’s performing well on the market, with high volume and support from major exchanges (most notably Bittrex) and looks like it’ll be around for a while.'
Ankr strives to build a resource efficient blockchain framework that truly enables Distributed Cloud Computing (DCC) and provides user-friendly infrastucture for business applications. There are indeed existing cloud solutions, but Ankr is the first one to leverage both blockchain and trusted hardware. Technology Overview Ankr provides a computation-resource-efficient blockchain and an integrated data feed system leveraging both cryptographic primitives and trusted hardware Proof of Useful Work The Proof of Useful Work (PoUW) consensus enables a self-sustainable blockchain framework. Instead of wasting electricity and computing power on hashes like Bitcoin does, PoUW uses these resources towards useful work tasks provided by enterprises and consumers. The protocol runs on SGX-enabled CPUs with remote attestation to ensure security and confidentiality. The novel PoUW approach unlocks the massive potential of idle computing power around the world by providing enough incentives: in this scheme, every computation contributor gets compensated, and some will get the extra reward for generating the blocks. In the future, this mining scheme can promote Universal Basic Income (UBI). Plasma Sidechains The Multi-chain Plasma implementation allows different applications to handle application-specific smart contracts on individual side chains, preventing transactions from overloading the PoUW-based main chain. Native Oracle Service Native Oracle Service (NOS) provides authenticated data feed by leveraging both cryptographic primitives and the trusted execution environment (TEE). Through a standardized API to port data from existing websites, NOS enables simple real-world business adoption
