BSC bridge multisig improvements

[robvanmieghem]

• Communication from the bridge master to cosigners is unstable threefoldfoundation/tft#117
• The way the BSC bridge multisig contract works is expensive threefoldfoundation/tft#170

I would make this an issue to improve all bridges for TF at once. To rewrite the bridges for eth / tfchain in a single project (preferrably rust)

Shared functionality:

• Stellar transaction streaming
• Signing transactions
• Communicating transactions between signer peers
• ..

@DylanVerstraete That's a different story imo

[DylanVerstraete]

I don't really agree with that, because to "improve" the things stated above, it will require some development work which can be directed towards a "fresh" start where we design the stuff from the bottom up again with all the knowledge we currently have. I believe redoing it will be the better solution here.

[DylanVerstraete]

Mainly because a lot of the functionality can be shared between the 2 bridges we have right now.

What is the status here, still feasible for 3.11? also should it still be linked to grid releases or can be in a separate project? @robvanmieghem

[despiegk]

lets just make sure its reliable for now, no need to rewrite, make sure we have it documented in our development docs (internal) / mdbook

Tested, small updates updated the docs to use the same code as the Ethereum bridge: https://github.com/threefoldfoundation/tft/releases/tag/v1.5.0
