In talking to people both familiar and complete strangers to Ethereum clients, these questions were asked more than once.
|

### Q: When do you expect to have it production-ready?
|
||
|
|
|
||
|
|
Soon. We've got some network simulations and a [public testnet](https://our.status.im/the-nimbus-mvp-testnet-is-here/) already running for [Ethereum 2.0](https://out.status.im/tag/two-point-oh), and we're syncing up to block 1.5 million on Ethereum 1.0. To stay in the loop, please follow our development updates on [our blog](https://our.status.im/tag/nimbus).

### Q: How is a super-light node different from just calling Infura through Web3js?
|
||
|
|
|
||
|
|
A Web3js or any similar JavaScript package for communicating with the blockchain is basically a more advanced XMLHttpRequest / Fetch wrapper. What we mean by this is that these packages retrieve information from another node and trust it implicitly. They ask "has this transaction been confirmed?" and get a response that's either "yes" or "that transaction is unknown".
|
||
|
|
|
||
|
|
With light nodes, they ask "give me the data to check if this transaction has been confirmed" and then check on their own. This is a trust-minimized setup which combines the best of both worlds - very little storage and processing power required while allowing for cryptographic verification of the full node's claims.

### Q: What's the plan for mobile?
|
||
|
|
|
||
|
|
While true that Nimbus only compiles to C, C++ and JavaScript and iOS and Android don't support C natively (and we definitely don't want a JS version of Nimbus running on a mobile device), native compiles with Nim work for both Android and iOS, just like geth written in go works. It's all NDK/C API. We'll soon have published specific instructions on how to compile it for all manner of devices, but you can already give it a go by following the [build instructions](/docs/building.html). Nimbus already runs just fine on OS X and any flavor of Linux, including a [NanoPC-T4 ARM](https://twitter.com/bitfalls/status/1111329152928485377) computer.
