Bitcoin Cash is a hard fork of Bitcoin with a protocol upgrade to fix on-chain capacity. Bitcoin Cash intends to be a Bitcoin without Segregated Witness (SegWit) as soft fork, where upgrades of the protocol are done mainly through hard forks and without changing the original economic rules of the Bitcoin. Bitcoin Cash (BCH) is released on 1st August 2017 as an upgraded version of the original Bitcoin Core software. The main upgrade is the increase in the block size limit from 1MB to 8MB. This effectively allows miners on the BCH chain to process up to 8 times more payments per second in comparison to Bitcoin. This makes for faster, cheaper transactions and a much smoother user experience. Why was Bitcoin Cash Created? The main objective of Bitcoin Cash is to to bring back the essential qualities of money inherent in the original Bitcoin software. Over the years, these qualities were filtered out of Bitcoin Core and progress was stifled by various people, organizations, and companies involved in Bitcoin protocol development. The result is that Bitcoin Core is currently unusable as money due to increasingly high fees per transactions and transfer times taking hours to complete. This is all because of the 1MB limitation of Bitcoin Core’s block size, causing it unable to accommodate to large number of transactions. Essentially Bitcoin Cash is a community-activated upgrade (otherwise known as a hard fork) of Bitcoin that increased the block size to 8MB, solving the scaling issues that plague Bitcoin Core today.

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.'
