H. R. 6572 is a bill that wants to help America be the best at using cool new technology called blockchain; it asks an important person, the Secretary of Commerce, to work on making sure everyone in America knows how to use and make the best of this technology. The bill also wants this person to tell the President and the people in Congress how well it's going and what problems they might face.

H.R. 8464 is like asking some very smart groups in the government to work together to write a big book about how people use a new computer trick called "blockchain" to make regular things like money or houses into special, digital versions. They have to talk to lots of people to make sure the book is really good and to see if they need to make new rules.
