How would you explain Bitcoin and blockchain to someone who is hearing about them for the first time? Wrapped Bitcoin coin

This is Wrapped Bitcoin (WBTC), which aims to combine the best of both worlds by bringing the value and liquidity (money) of Bitcoin to the dynamic and rapidly evolving world of DeFi. Wrapped Bitcoin was brought to the world as a collaborative project between major players in the DeFi ecosystem, such as BitGo, Ren, Dharma, Kyber, Compound, MakerDAO, and Set Protocol, in an effort to bring more liquidity into the Ethereum network by dipping into Bitcoin.
