Lambda is a fast, safe, and scalable blockchain infrastructure project, which provides decentralized applications (DAPPs) data storage capabilities with unlimited scalability and fulfills services such as multi-chain data co-storage, cross-chain data management, data privacy protection, PDP, and distributed intelligent computing through logic decoupling and independent implementation of Lambda Chain and Lambda DB. Through the logical decoupling and separate implementation of Lambda Chain and Lambda DB, we provide infinitely scalable data storage capabilities to decentralized applications and achieve Multi-chain data cooperative storage, cross-chain data management, data privacy protection, data ownership proof, distributed intelligent computing and other services. Additionally, as the underlying service of blockchain, Lambda Chain provides millions of requests per second (RPS) through Sharding technology, which can grow as the scale of the system expands; and it also offers technology service capabilities for future unlimited expansion through sub-chain technology. We believe that all storage projects follow the core requirement of Provable Data Integrity.Also, it is crucial for data projects to store data in an infeasible storage node and make them trusted and secure, in the academic world, there are mainly two approaches which are Provable Data Possession (PDP) and Proofs of Retrievability (POR) depending on the usage scenarios. Lambda has applied these two approaches in blockchain through academic research and engineering verification, which has eliminated the core obstacles of decentralized storage.
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.'
