Governor: Acala parameters

[tbjump]

Over the last week, there has been a significant increase in transfer activity from DAI on Acala to Ethereum.

Looking at the Dashboard, the Governor "fast transaction limit" is currently exhausted with five VAAs already enqueued.

Raising the Governor limit would expose the Token Bridge to a higher security risk if there was a vulnerability on the Acala blockchain, but since the launch of the Global Accountant, the cross-chain risk is limited.

Acala has received multiple third-party audits and runs a bug bounty program.

From a security perspective, I would support raising the Governor fast-transaction limit from $500/$50k to $1M/$100k notional to meet user demand and re-assess the situation if demand falls back down.

I would appreciate feedback from Guardians if they would adopt a $1M/$100k setting for Acala if it were to become part of the reference implementation, or alternatively which limits they seem to be appropriate.

I think we should support users demand whenever security isn't a problem. It feels secure to us (Triton) to raise this limit.

It seems like demand on Acala went back to normal and a modification of Governor parameters is no longer needed. I will therefore close this discussion for now.
