In 2018, the LockTrip team released the LockTrip Blockchain Manifest, which became the foundational design document for the Hydra Chain. This document addressed real challenges encountered during the development of the LockTrip dApp. To create an optimal solution, the team adopted an evolutionary approach, building Hydra on top of proven open-source technologies, a strategy successfully used by major blockchains like Bitcoin Cash, Litecoin, and Qtum. Hydra's philosophy is to incorporate essential economic features while utilizing established technology for data transmission. Hydra is a permissionless, open-source, proof-of-stake blockchain that builds on projects such as QTUM, Bitcoin, Ethereum, and BlackCoin’s PoV v3, designed by Pavel Vasin. Alongside unique economic features, Hydra encourages stakers and market participants to support its decentralized architecture. Hydra offers fixed transaction fees in USD, dynamically calculated in Hydra based on market prices, providing businesses with on-chain predictability and reducing the risks of blockchain-based operations. Additionally, Hydra's gas royalty feature shares 50% of transaction fees with smart contract creators, fostering a fair incentive structure and making the chain highly appealing to developers.
