So... Smart Filters!

Question

Once a smart filter (transaction-filter) is approved, is it applied to all transactions on that blockchain from that block onwards?

Please define a callback in layman's terms.

Can one smart filter reference another?

Thanks

Answer 1

If a transaction filter is approved (to the necessary level of consensus) in a blockchain transaction, then any subsequent transaction in the chain must pass that filter, until (optionally) the filter is disapproved.

A callback is just a way for Smart Filter code to make a request to MultiChain, in order to get the information it needs.

For now one filter cannot reference another, or share code with another. Or at least not yet...
