Introducing 0x Protocol V2

The first versions of the smart contracts that implement the 0x protocol were deployed to the Ethereum mainnet in August 2017. Since then, the 0x core team has been shocked by the positive response…

Can you explain what the ability to create “filter contracts” for permissioned liquidity pools means and why it's important?

@soonaorlater Definitely! Will outlined this idea in detail in Compliant Peer-to-Peer Trading (https://blog.0xproject.com/compliant-peer-to-peer-trading-4dab8e5c3162). In short, the concept is that a relayer can deploy a 'Filter' contract that orders must pass through before being passed to the 0x Exchange contract for executing the trade. This Filter contract can, for example, verify that the person making or taking the order is on a KYC whitelist to ensure that the traders using the relayer are trading with other known traders. We expect to see people taking this Filter concept and taking in creative new directions!

Is there a backward compatibility to V1?

@dstuecken Because the exchange contract address is part of the order format, orders that were created using V1 will not be fillable with V2 and vice versa. Users who allowed the 0x V1 proxy contract to execute their trades will have to set this allowance again on V2 proxy contracts, but we're in the process of releasing an awesome new 0x Portal to make this process as smooth as possible! Additionally, relayers will still be able to use V1 for a few months as they transition to V2, but we will turn off the ability for V1 to fill orders in the future.

Does this update effect holding 0x token in any way? So do investors have to do anything? 😊

@dstuecken Nope, hodlers can keep hodling! We're working on bringing governance to the 0x Protocol in stages (https://blog.0xproject.com/governance-in-0x-protocol-86779ae5809e), so token holders will be able to vote on changes to the protocol in the future!

As someone who was formerly @facebook/instagram and currently in the crypto space, any guesses as to what direction David Marcus might take with the new blockchain division at FB?

@atyreefinch I'll try to hold off on speculating too much in public :). Facebook has world-class engineers, designers, PMs, etc. and tends to move very deliberately. I would expect to see a real consumer product come out of this effort and FB will probably pull out all the stops help it get adoption. Say what you will about FB's products, but growth is their bread and butter.
