Plain-language change summary

The amendment to HB 639 removes the definition of "home digital asset mining" and the definition of "private key." Instead, it retains definitions for "node," "self-hosted wallet," and "smart contract," which clarify how these terms relate to blockchain technology. Additionally, the bill establishes a blockchain dispute docket to oversee related disputes. These changes help provide clearer definitions within the legislative framework and detail how blockchain technology is managed in the context of disputes.
