Note that the protocol differs a bit from #895 in its notifications format, to avoid additional server-side processing we're omitting some metadata like: * block size and confirmations * transaction fees, confirmations, block hash and timestamp * application execution doesn't have ScriptHash populated Some block fields may also differ in encoding compared to `getblock` results (like nonce field). I think these differences are unnoticieable for most use cases, so we can leave them as is, but it can be changed in the future.
