Washington has introduced a new bill, SB 5638, to recognize and promote blockchain technology, amending the Washington Electronic Authentication Act to provide legal recognition for digital signatures and a voluntary licensing mechanism for certification. This initiative is part of a broader effort to enhance the use and understanding of blockchain across various industries while addressing the need for regulatory frameworks. The state's technology hub, including companies like Amazon and Microsoft, positions it as a leader in blockchain development and encourages future growth in this sector.
