Factom is the first usable blockchain technology to solve real-world business problems by providing an unalterable record-keeping system. By creating a data layer on top of the Bitcoin blockchain, Factom’s distributed ledger technology secures millions of real-time records in the blockchain with a single hash using cryptographic isolation. Businesses and governments alike can use Factom to document their information so that it cannot be modified, deleted or backdated. Factom’s technology decentralizes record keeping by ensuring that the integrity of stored data remains intact, providing complete transparency, while at the same time maintaining user privacy in an increasingly digital world. The Factom project began in 2014 which puts it on the older end of the blockchain spectrum. The team has made steady progress since then. They released the first version of Factom in early 2015 and had their token sale in the middle of that year. In August of 2015, they were accepted into the Plug and Play FinTech accelerator and were chosen as one of Austin’s A-List start-ups in May 2016. Based out of Austin, TX, the core team has multiple members with several years of experience in the blockchain space. Peter Kirby, Factom Co-founder and CEO, and Abhi Dobhal, VP Product Management, previously worked together at CoinTerra, Inc – a producer of ASIC miners for Bitcoin. The price of a Factoid is directly tied to the amount of network usage. As more businesses join the network, it will become more costly to submit Entries which will, in turn, affect the Factoid price. Once the number of Factoids being burned outpaces the 73,000 that are created each month, the currency will become deflationary. This may drive the price up even further.
Hcash is a new cryptocurrency designed to allow value transfer among blockchains and between blockchains and blockless cryptocurrencies. In addition, Hcash will support private transactions, DAO governance, and quantum resistance. Since Hcash hopes to be a side chain for many different cryptocurrencies, including privacy coins, it will need to implement privacy features to mask how users are moving their funds. To address this issue, Hcash will come with two types of wallets: white and black. While the white addresses will be publicly viewable, the black addresses will remain private. In order to achieve this privacy, Hcash will implement zero-knowledge proofs. This system, as proven on Zcash’s blockchain, involves masking the identity of the sender and receiver through the use of advanced cryptography to verify transactions without sharing information about the transaction with miners. As a result, blockchains that implement zero-knowledge proofs do not include any identifiable user information. Hshare offers enormous technical potential in the industrial, private network sector. Multi-compatible and multifunctional software, which is already designed for quantum processors, makes it possible to combine a wide variety of crypto technologies. This offers advantages in the FinTech area, in finance, in dealing with Big Data and also for the application area of the Internet of Things. Hshare seems to be not subject to any limitations.
