ETH Exploit, Chain Halted and information gathered

THORChain suffered another ETH based exploit and the protocol was halted again with the intention of it being a longer halt. This promoted a very large community response. Data has been collected regarding the exploit.

The Data https://www.notion.so/THORChain-Incident-07-16-e08a7be6cf4c4bce95ba2636759709e2#c5f8922b241c47888767012c89a8af1d

The Proposals going forward https://www.notion.so/Proposals-6eb7f21707f647fe8dbbd5ae5867a044

Information is being reviewed — it take time before the protocol can be fully operational.
