> Reported the problem to bitcoincore-rpc [rust-bitcoin/rust-bitcoincore-rpc#225](https://github.com/rust-bitcoin/rust-bitcoincore-rpc/issues/225) I tried fixing this in https://github.com/rust-bitcoin/rust-bitcoincore-rpc/pull/230, however my changes seemed to have broken backwards-compatibility and I need to fix the tests.

It seems that the link you provided is the solution that everyone is using. https://github.com/rubocop/rubocop/issues/8697#issuecomment-690875556

I would be interested in having a go at this issue.

@i5hi you can also create custom Database implementations outside of BDK.

> I have been witnessing few occasional failures in blockchain tests in my local too.. Seems like some kind of resource blocking thingy happening somewhere?? I was seeing "resource unavailable"...
