You could even throw a random transaction verification into the mix.

I like the scoring approach because it makes use of a  unique set of circumstances we have access to: a second tier where you can introduce queries and additional checks to validate against fake nodes.

One of the things you can do, for example, is triangulate ping and query response rates. If I ping nodes in my immediate network I can record the ping times of my group of connected nodes.  If I ping and query, the query times should have some level of correlation, unless you are running a fake node. A fake node has to send a request to another node (hey, AnotherNode :-)) in order to get data to respond to the queries it is being asked for.  Do this enough times and you will be able to figure out who are the fake nodes, but even if they are not fake you can score them down.

If you add random ping and qurry rules into the equation, then you can avoid someone trying to game the ping and queries by running 5:2 bitcoin full nodes to fake nodes.

On the developer slack channel there have been numerous conversations about whether PoBN would be open to abuse by service node operators running multiple full bitcoin nodes sharing a single blockchain.

I have been doing some research into this over the last few days and I think that it isn't necessary to require cryptographic proof that a bitcoin node is using a unique blockchain copy.

Bitcoin Core (and XT for that matter) uses a database lock which locks the Berkeley Database when a blockchain is mounted and prevents another instance from connecting to the same blockchain copy.  This lock was put in place because if you have multiple bitcoin instances reading/writing to the same blockchain, near instant corruption occurs stopping synchronisation and forcing a reindex.

It is possible to over-ride the lock by deleting the lock file and opening another instance but blockchain corruption is rapid, almost instantaneous.

Does this mean that if a service node is scoring well in quality of service and has an up to date block height it can be trusted as a unique node?  

I have been trying to find some time to mine ETH, so I can sell for SPR.  Those SPR miners by Wolf0 make it tricky to mine direct.

The main issue that's stopping me mining ETH is of my own making. I have managed to brick four rigs because I left them unused for a few months in my cold garage which i had vented for mining, and I guess some of the rigs just want to be kept nice and warm.

I guess ETH is taking miners at the moment

Looks like big difficulty drop. Whats up with that?
Fire up the spreadminers folks!

What a really interesting chart.  Its got the brain cells working away faster than normal. There is a mention of side chains with bitcoin in the PoBN white paper, but if Dash were to add support for side chains, then that opens up so many opportunities for every project. Great contribution, thanks.

Absolutely.

Each successful testnet version should immediately be converted into the next mainnet version.

So when we are at testnet version2, we will simultaneously have moved to mainnet version 1.
Starting testnet version 3 means we are now at mainnet version 2,

etc

That's how its supposed to run, if we are to get the maximum network effect out of our ongoing development.

But it's ofcourse entirely possible that we will have a few isolated testnet versions inbetween, before we think that's now worthy of a new mainnet version,
like when we try to solve a particular persistant problem.

But then again, that's why I do lots of preliminary testing in my private network.

There's no need to engage the whole community in my debugging sessions, that wouldn't make sense.
No, testnet means we are testing something that I think is already pretty stable and now ready for a fieldtest.

Music to my ears 

Well, we will follow standard procedure: Test until we have a stable functioning version,
and try to bring it as quickly as possible to mainnet, even if it is not 100% complete (functionality wise).

It's important to start building a strong network as soon as possible.

Quick crazy question - when the test net goes live what is the length of time that we will be testing?  BTW - I am getting back on my feet and slowly accumulating. :-)

lol, no means no right? 

Yes, that's a pretty neat idea, with like mindboggling potential.

I say once we have achieved a BreakThrough (see roadmap), we can always slightly adjust the roadmap to factor in new ideas (research areas), before we continue to the next BreakThroughs.
It's good to be that flexible. But it's also absolutely necessary to keep working rigorously towards the nearest goal!

Without deviation.


I'm looking at you, kid!  

Yes, I couldn't agree more.
Currently I have to juggle too many priorities (spreadcoin community, my customers, private life), and everybody is pretty anxious to get my full attention.

I'll do the best I can to not worsen the situation (by NOT adding more factors into the equation) and the goal is to basically turn spreadcoin community into my main customer soon (thereby reducing the factors).

It should get pretty interesting to see how this will look like: to work for a community as the dayjob!  

Thanks!
There is nothing more motivating than receiving donations in SPR!
So yeah, I highly welcome additional encouragement of this sort!

I agree with you, and I know SPR has got a huge role to play.

Even though I am but a mere newbie, I dare ask if what came to my mind would be feasible for Spreadcoin:

I guess what I'm talking about SPR having a sidechain on each main cryptocurrency...

... does it at least make any sense (coding illiterate here  )

Please, keep up the amazing work! Do your best!

IMO, I don't think exact dates matter now, but it does look like testing will begin in Feb.  

Georgem has given a reasonable time window, but the more important announcements that haven't been factored and which should give this community huge confidence is that Georgem says this is going to be a full time effort and he will likely do a video update.

Back in May 2015, there were discussions about a p2p exchange. That was based around creating some form of anonymous accounts hosted by serivcenodes to create a decentralised form of Coinbase.

A few months ago Evan over at Dash began releasing details about Evolution which we now know has some similar ideas.


What would be really interesting is to find a way to create a bridge between two crypto currencies using the serivcenodes / masternodes.  This is like currency transfers in the real world and would open up a path over the next 10-20 years for nations to adopt crpto as a mechanism to digitally transact their national fiat currencies - although that opens up problems with regulations  that might be difficult to resolve in the immediate future.

Still the Evolution work is likely to take between 12 months to 24 months and that is the timing for getting 3000 to 5000 bitcoin nodes on the network, so a few weeks to wait for testing is no big deal when the size of the prize is a decentralised Coinbase and PayPal, with an ability to exchange value with bitcoin, Dash, SPR, ETH, etc.

Crypto has never been so exciting as its about to get.

Let me get this right. By the 7th (latest) i will be able to test a service node on testnet?

If so will they have decentralised block ex?

  My impatience is masking my excitement, I'm just really pumped for testnet whenever that may be. Certainly I'm glad you're taking the methodical approach as the ambitions of the project reach uncharted waters.  Gonna donate to your dev fund as a sign of appreciation for your hard work and would encourage others to do the same

Being creative like that is fun and relaxing, so when spreadcoin has replaced my dayjob, I'll keep creating animations in my freetime, why not.
Can't wait to show you some of my music too.  

I don't wanna be one of those savant syndrome coders... very good at one thing, but still an idiot.  

My approach to everything is very interdisciplinary!
