It has been an eventful week in Witness World.

There has been one new witness arrive.

And there has been one old witness leave - under unfortunate circumstances.

Aside from these arrivals and departures there have been no major movements in the witness rankings.

If any witnesses have any information they would like to share feel free to contact me on Discord (Pennsif#9921) or leave a comment below.

There are a further 30 or so active backup witnesses mainly in the #20 - #45 slots.

All top 42 witnesses are running the current 0.23.1 version.

Most of the witnesses from #43 and below are 'former' witnesses that are running old witness versions (0.23.0 or 0.22.1) and have now moved to another blockchain.
