What is DeFiChain
DeFi stands for Decentralized Finance. It describes the idea removing the trusted third-party to execute financial services, with a blockchain in its place to enable people, and in the future, machines to become their own bank for these services, removing counterparty risks.

Why not use the Bitcoin blockchain?
The Bitcoin blockchain was created for a single specific financial service – the decentralized and censorship-resistant store of value used as a medium of exchange, and perhaps a unit of account in the future.

Ethereum was meant to be a general-purpose platform. In principle, one could do anything with Ethereum, rendering it the jack of all trades but master of none. Problems such as the DAO and parity hack reveal the challenge to keep smart contracts secure, due to their general and universal nature.
