The project you mentioned is extremely interesting. I'm reading their white paper and will reach out. Thank you!

To access all the wallets and their relevant balance I have some queries in this blog: https://www.dolthub.com/blog/2022-06-01-free-the-sql-data/. I can add an addresses table as a generated view for sure

I launched an open-source Bitcoin database https://www.dolthub.com/repositories/web3/bitcoin. Anyone should be able to clone and run mysql queries on top of it. It's built on a database tool called https://github.com/dolthub/dolt.

Let me know if this interesting, this current database is a little behind the head block but I have a more optimized database of Bitcoin coming soon.

I open-sourced the Bitcoin blockchain https://www.dolthub.com/repositories/web3/bitcoin. It's a little behind (will catch up soon to the head block) but you can easily query all wallets in SQL with it. CC this blog https://www.dolthub.com/blog/2022-06-01-free-the-sql-data/ for some ideas.

If you know SQL, I put together a Bitcoin database https://www.dolthub.com/repositories/web3/bitcoin that is currently updated till 2013. I have a more optimized database on the way that will be easier to download and work with. If interested, I can help you with the SQL queries.
