Resurfaced 1998 video shows Bitcoin pioneer Hal Finney's early grasp of crypto concepts like zero-knowledge proofs and NFTs

Video of Bitcoin pioneer Hal Finney discussing zero-knowledge proofs in 1998 resurfaces. He credits the protocol's invention to Cramer and Damgard.
Zero-knowledge proofs help secure and scale blockchain networks. They are used in rollups to bundle transactions.
There are two types of rollups Optimistic and Zero Knowledge. The latter relies on zero-knowledge cryptography.
Hal Finney received the first Bitcoin transaction from Satoshi Nakamoto in 2009. Some believe Finney was Satoshi or part of the group.
In the 1990s, Finney referred to NFTs before they became popular. The video shows his early understanding of crypto concepts.
