#### Implementation notices
##### `getaccountstate`
The order of assets in `balances` section may differ from the one returned by
C# implementation. Assets can still be identified by their hashes so it
shouldn't be an issue.
##### `getapplicationlog`
Error handling for incorrect stack items differs with C# implementation. C#
implementation substitutes `stack` and `state` arrays with "error: recursive
reference" string if there are any invalid items. NeoGo never does this, for
bad `state` items it uses byte array susbstitute with message "bad
notification: ..." (may vary depending on the problem), for incorrect `stack`
items it just omits them (still returning valid ones).
##### `getassetstate`
It returns "NEO" for NEO and "NEOGas" for GAS in the `name` field instead of
language-aware JSON structures.
##### `getblock` and `getrawtransaction`
In their verbose outputs neo-go can omit some fields with default values for
transactions, this includes:
* zero "nonce" for Miner transactions (usually nonce is not zero)
* zero "gas" for Invocation transactions (most of the time it is zero).
##### `getclaimable`
`claimable` array ordering differs, neo-go orders entries there by the
`end_height` field, while C# implementation orders by `txid`.
##### `getcontractstate`
C# implementation doesn't return `Payable` flag in its output, neo-go has
`is_payable` field in `properties` for that.
##### `getnep5transfers`
`received` and `sent` entries are sorted differently, C# node uses
chronological order and neo-go uses reverse chronological order (which is
important for paging support, see Extensions section down below).
##### `getrawmempool`
neo-go doesn't support boolean parameter to `getrawmempool` for unverified
transactions request because neo-go actually never stores unverified
transactions in the mempool.
##### `getunclaimed`
Numeric results are wrapped into strings in neo-go (the same way fees are
encoded) to prevent floating point rounding errors.
##### `getunspents`
neo-go uses standard "0xhash" syntax for `txid` and `asset_hash` fields
whereas C# module doesn't add "0x" prefix. The order of `balance` or `unspent`
entries can differ. neo-go returns all UTXO assets while C# module only tracks
and returns NEO and GAS.
##### `getutxotransfers`
`transactions` are sorted differently, C# node uses chronological order and
neo-go uses reverse chronological order (which is important for paging
support, see Extensions section down below).
##### `invokefunction` and `invoke`
neo-go's implementation of `invokefunction` and `invoke` does not return `tx`
