`Motivation`
As the network evolves and increases its interoperability, there is a natural need to support tokens with a number of decimals that would overflow uint64. This requirement was also pointed out by Mr. Kaine.
`Implementation`
Each struct that contains a `big.Int` field and is returned by RPC now has two additional methods: `MarshalJSON` and `UnmarshalJSON`. These methods override the default behavior in `json-rpc` when marshaling a struct to create an RPC response. The object will now be returned as before, but the `big.Int` field is returned as a string.
In every test, the changes include wrapping each `big.Int` inside " ". For getDepositedQsr and getQsrRegistrationCost, a new variable was included because the newly returned type is a string. In pillar\_test, a few extra expects were added. Each test runs smoothly.
These changes do not affect consensus or the way nodes communicate or synchronize and can be considered a soft fork. However, it is considered a hard fork for every application (such as Syrius or web apps) that is using an older version of the `SDK` which does not contain these changes. `SDK` developers would need to update them, and all apps should be recompiled using the new `SDK`.

Awesome! That combination of JSON and BigInt was creating issues for most SDKs.

I’ve started working on Syrius and the Dart SDK.
