[Passed] NuDroid upgrade v5 (April 2016)

[Cybnate]

Proposal for NuDroid upgrade

It has been over a year ago when the previous large upgrade grant passed. The App has been stable and useful, but doing nothing is going backwards in this fast moving world of crypto-currencies. So time to look at this again.
After quite some preparation work and some teasers I’m proud to present to you the draft custodial grant proposal to significantly improve the NuDroid App in a bid to increase the demand for NuBits. The proposal is split up in 5 sections;

1. Explanation and rationale; What is NuDroid and why this proposal?
2. Overview releases, time and costs;
3. Marketing
4. Contractual context
5. Detailed description of releases.

The intention is to discuss and finalise the custodial grant in the next 10-14 days and bring up the final grant for voting thereafter. The amounts mentioned for the releases and the total amount are estimates based from a draft contract and subject to negotiation with the developer or myself. The item around changing the currency from NBT to US-NBT in NuDroid is still being worked on and may need to be added to the cost TBC. There is also an option to update the user interface presented at the bottom of the grant which hasn’t been included awaiting feedback.

I recognise that this is a significant investment for Nu. However I think it will eventually provide good value. I have tried to provide easy to read overviews and at the end of the proposal a detailed description of the functionality for those more technically oriented. The text under ‘Requirements’ will also be added in the contract.
It is quite a read, but a major release like this is likely only to happen once a year and given the size adequate due diligence is required. Thanks for your time and consideration.

The proposal can only be finalised and submitted for voting when a contract with the Developer and Custodian has been agreed. This leaves flexibility for feedback and comments to be taken into account.

Oh, BTW here is the link to the full proposal:

Thank you for improving NuDroid an drafting this comprehensive contract.

There’s one thing I don’t understand:

The Child-Pays-For-Parent functionality wont be necessary for Nu, so that wont be included, nor will the fee behaviour changes, and anything to do with sweeping wallets.

wouldn’t fee beaviour changes need to be supported, if a fee different from 0.01 NBT/kB shall be recognized by NuDroid?

[Cybnate]

wouldn’t fee behaviour changes need to be supported, if a fee different from 0.01 NBT/kB shall be recognized by NuDroid?

Great, just one thing?!

Fee changes are already supported by a previous release. The referred changes in bitcoinj relate to fee changes in Bitcoin, which are not required.

[masterOfDisaster]

I often need time to digest complex things.
This was just the first finding that struck me
Maybe I come back with more of that or even suggestions to improve it?
Not very likely, because the draft is already in an impressive shape!

[Sebsebzen]

Integrating Ethereum would be an excellent move judging by the current trend. It also would allow us to raise interest within the Ethereum community, especially since Vitalik has recently tweeted that most DAPPS would require some form of stablecoin to work. To be realistic, NuBits has been more or less ignored by the wider Bitcoin audience.

[willy]

Are there any plans to improve the current peer discovery work around?

No one stepped up to create a second DNS seed so far. If nuseed.coinerella.com fails, NuDroid fails.

I also feel that the current implementation for dynamic fees is more or less a work around as well.

VPS, Hébergement VPS, Anti-DDoS, Serveur Privé - Dedimax.com

what LC plan would be the minimum to handle this DNS seed thing?

[willy]

It’s very slim.
I ran it on a Raspberry Pi B+.

[zoro]

And what is the cpu/mem utilization?

[willy]

Next to nothing… the DNS seed creates a lot of sub threads. The PHP script doesn’t create much load either, most of the runtime comes from the lag of the CloudFlare API.

[masterOfDisaster]

I have put this on my to-do list!
Thank you for reminding us.

[Cybnate]

I also feel that the current implementation for dynamic fees is more or less a work around as well.

You might be right, but will need to have @MatthewLM to comment on it.
Anyway, the risk is that anything changed now might need to be revisited again when Nu 3.0 is released. I rather wait until it is more clear how that is going to look like and what changes might be required.

And thanks for the reminder, will have a look whether it is feasible for me to add the Nuseeder to the https://svr1.nubitsexplorer.nu server.

[MatthewLM]

The implementation for dynamic fees as it stands was done to avoid implementing details to the Nu protocol in regards to fee calculations, which are indeed unknown for Nu 3.0 at this point in time. This was largely to make costs lower. The way NuDroid fetches fees should hopefully work with Nu 3.0 when it is released in the future, but to implement the logic from within the app itself, I would need to know the way Nu 3.0 will work.

I can add any new DNS seeds to the app during a release with no problem. Indeed it would make the app more resilient by having no single-point of failure. Though the app can do peer discovery without a DNS seed; it’s just much slower and more unreliable.

[Cybnate]

Just made a few changes to the proposal and I consider it now a final draft.

Change log:

• Renamed title to v5 April 2016
• Removed optional material theme text from proposal.
• Added release 1E which transitions from NBT to USNBT and has approach for change in Shapeshift.io api.
  This results in an increase of the duration to 7 weeks (was 6) and total cost increase to 16,350 (was 15,350).
  More details in the proposal.

As I have not seen any comments on the optional release for the Material theme I decided to leave it out in the final draft.

The intention is to release it for voting in the next few days, so please let me know if you still have some feedback or comments to improve it or just to support it.

[Cybnate]

Bump, any more comments. No opposing views I can address?

[cryptog]

What is the hourly rate?

[Cybnate]

There is no hourly rate. It is a negotiated fixed price proposal.
I’m currently finalising the contract with Matthew and make some final adjustments and submit it for voting if there are no other comments.

[Cybnate]

The underpinning contract with the developer for this grant has been finalised and I have updated the proposal at Daology accordingly.

The latest changes include:

• Proposal negotiated back to 16,000 NBT
• Added in the setup of another NuSeed instance (item F) at no additional cost.
• Extended timeframe release 1 with one week

Thanks for your consideration.

[cryptog]

I will put on hold this custodial grant vote until the liquidity issue is solved, hopefully quickly.

[masterOfDisaster]

Impeding development saves some bucks, but prevents useful tools from being created.
I’d rather see an NSR sale than saving money here.
The liquidity operation costs a lot of money and there’s a lot of potential for saving, but that road isn’t followed seriously.
Why make cuts here instead?
This has the potential to increase adoption.
