fjahr commented 9 months ago

This adds the asmap.dat result for the coordinated launch from https://github.com/fjahr/asmap-data/issues/9 from the epoch 1706536800. We had a match from 4 out of 6 participants in the coordinated launch.

To confirm the result of the encoding you also need to check out https://github.com/bitcoin/bitcoin/pull/28793 to get the latest version of asmap-tool.

I have a matching asmap.dat with 2155eab71080099f469c524e49ff71d264859b023431b27aa52f58315a640ff1 too!

Loading that file also seems to work. However, it prints a different version/hash. Not sure how this hash is calculated.

Yeah, it prints a double-SHA256 hash of the decoded data. Not sure it is needed to print the file hash as well. I will keep it in mind if this keeps confusing people.
