Hi the xDai TokenBridge validators!
In order to improve the security of the Arbitrary Message Bridge deployed between the Ethereum Mainnet and the xDai chain by increasing the number of the oracles (currently we have 3 oracles and 2 of them must confirm the message relay) we suggest to utilize the nodes where the current xDai TokenBridge oracles are set to add the AMB workers there.
The current security improvement is important step since the AMB bridge is the key component for the OmniBridge that allows users to transfer any ERC20/ERC677 token from the Ethereum Mainnet to the xDai chain. We have completed the security audit for the OmniBridge contracts recently so with the next upgrade its beta phase will be finished and the bridge will be officially opened. Currently the bridge keeps assets with total value more than 2.2M. The value of tokens locked on the OmniBridge will increase as soon as we finish the development for the reversed OmniBridge that will allow to send ERC20/ERC677 tokens that are native w.r.t. the xDai chain (like HNY or CLS) to the Ethereum Mainnet.
It will require to generate to generate a new private key which is going to be dedicated only for AMB oracles needs – confirm message relaying from one chain to another.
The deployment process to combine to oracles together is quite tricky and will be described later. In order to have enough resources on the node to have combined setup we recommend to double check that it has at least four cores and 4GB of memory.
So far, if you are agree to extend your node to have AMB workers also, please send the address that corresponds to the new private key to this forum post. We will raise the governance call to add these addresses to the AMB validators contract.
If you have any question, write a note below this message.
