HydraChain, the brainchild of Saar Yaari and Tal Kol, is a permissioned blockchain platform that allows for comprehensive control by authorized participants to create and control their own distributed ledgers – or Hydraledger (HYD) as it's otherwise known. With HydraChain, users are able to deploy and use their own customized blockchain which is built off of the Ethereum platform. Hydraledger is perfect for enterprise-level applications that require a private, secure, and data-intensive tool. It is specifically designed for businesses or users who need to have large amounts of sensitive data distributed or encrypted in a secure way. The blockchain uses Hydra protocol to control its distributed ledgers, giving users a great degree of control over the data. For example, Hydra protocol allows companies to control who are allowed to modify the LEDGER, who can view or share the data, and even who can audit the integrity of the ledger. All this is safely done without compromising any kind of data privacy as HydraChain only uses a minimal amount of public data which is kept encrypted within its blockchain. HydraChain seeks to improve the scalability, control and privacy of blockchain technology, allowing developers to increase speed and reliability in their transactions. The main goal of HydraChain is to provide the tools needed to enable enterprises to utilize the power of blockchain in various forms, from supply chain management to financial services. One of the things that makes Hydraledger unique is its use of Jupiter, an open source Hydra virtual ledger network. This network allows parties to securely share data across different blockchain networks and to maintain cryptographic proof of data authenticity and integrity. This makes it an ideal platform for trading security tokens and finance/payment solutions. Hydraledger coins and tokens can be bought and sold on exchanges such as Bitfinex, and crypto services such as Coinbase and Kraken. They can also be purchased with credit cards or debit cards using services like Changelly or Simplex. In addition, they can be purchased using traditional fiat currencies such as dollars, euros or yen. However, it is important to note that these transactions can also be subject to market volatility. In conclusion, Hydraledger is an open-source blockchain platform that provides developers and enterprises with a robust and secure blockchain network. It is well-suited for applications that require data-intensive operations, privacy, and scalability. As it is based on the Ethereum platform, it is also compatible with existing systems and applications. Additionally, Hydraledger coins and tokens can be bought and sold on exchanges, as well as with traditional fiat currencies.
