Any idena when sharding & oracle?

"There is a new version of the Idena node available: 0.23.2

Changes:
- Peer discovery improvement
- Validation bug fix

Update is recommended for the successful validation"

Acording to @Tytanowy Janusz, we are on the mainnet already.

When is the mainnet again?

I participated in their Twitter companies, only not for coins ,but for invites and received 2 times from them invites for small actions on Twitter, you need to try to participate now and here , when will the next contest be held 

I've been following this, but unfortunately I still haven't managed to get a giveaway from them, but I will try it as long as they continue to hold it every week, congratulations to the winner

Sharding is not needed untill we reach 8-9k identities. We have long way to reach that number. There is no network congestion. If there was network congestion I and other people who are more tech savy and know how to setup idena good, would randomly fail validation due to congestion. But that is not the case. Regular people just fail at running node as good as they should. Shared node as a service will be salvation for them. I have allready started making list of people who failed validation and talked to me. I have offered to them to try Web validation over shared node that I will have up and running for next validation.

I have written post about good setup for validation long time ago and i send it to every new member that i chat with:

It is recommended to go to through pre-validation check of your technical setup of Idena App and node. It will be a lot of information, try to do things that seem easy enough for you to do. Please consider these few advices:

1. Time synchronisation
Time synchronisation is of great importance for successful validation. Experience tells me that Windows users are affected mostly with time synchronisation issue. Thing is, windows has built-in time synchronisation which synchronises time once in 7 days. So it is very likely that you will be out of sync to some extent on validation day. To check how much in sync your PC is right now, visit time.is website.
Problem:
What can out-of-sync cause during validation? It can fool Idena app to show you wrong time during short session. You can have 16 seconds displayed as remaining time, but in fact if your PC time is out of sync for let's say 19 seconds, you have already missed the time to submit your answers, so you can fail validation short session with result "Late Submission".
Solution:
Install free program that can sync your time more often. You can download it by visiting website NetTime, or download it directly from this http://www.timesynctool.com/NetTimeSetup-314.exe. Allow it to be installed as a service so it runs automatically in the background.


2. Internet connection
Idena at home:
If you run node in a home environment, there is whole lot of things to consider that can cause problems:
- Router quality: Did your internet start disconnecting from time to time while using idena? Many home routers are made in low quality and can't handle this kind of traffic and connections that Idena is making. Regular cisco will work like a charm. If you replace your current router that is disconnecting with some regular cisco or mikrotik, you will not have problems. You can restart your router one day before validation so it clears its cache if it has any, so it can serve you as good as it can on validation day.
- Wi-Fi: Are you running Idena on laptop over Wi-Fi? How good is your Wi-Fi? Since wifi is something unpredictable, if you know from experience that your wifi is sometimes unstable, it is recommended to hook up a lan cable during validation session so you avoid potential problems.
- Other people in house and programs: Are you running other programs like torrent or are you on a shared internet? Turn off all other things that are using internet during validation time, and ask your roommates/family members not to use internet during validation time (It's just 15min once in a 2 weeks).
- Internet speed: I don't have exact data but 2mbps of upload speed would be questionable recommended minimum for validation of one Idena on that internet using --profile=lowpower option. See how to setup that option on this video (read video description).


3. Hardware resources and performance
Hardware requirements is complicated subject as there are many possible setups and pc hardware on which you can run full Idena App or just node. As I don't have much experience with all devices (like RaspberryPi or Mac's) and operating systems like all possible Linux distributions, I will try to give general suggestions.
CPU power: validation is more cpu intensive than in-between validation node mining. So if your mining is working ok, that does not mean that your validation will go ok if you limit your CPU for Idena in some way. If you use Idena on laptop on windows and connect to it remotely, don't close lid of your laptop as it will disable graphics card and your CPU will maybe have problem to deal with all that needs to be done and possibly go out of sync during validation. Also some PC's/Operating systems disable graphics card if you don't have monitor attached, that can also cause issues in getting all computational load on CPU.
RAM memory: I have noticed that node starts by using 200MB of RAM. Over time, if you don't restart it, it consumes more and more memory. I have seen it go up to 800MB after 7-10 days of non stop activity. This is very problematic for VPS that have 1GB of RAM. If you have swap file(virtual memory on hard disk), it will help but not for long. After some time I guess CPU has to deal with node and ram and swap and node starts to go offline from time to time. It is very recommended to restart your node one day before validation. Not right before validation as then load on network is high and if you are not lucky, you might not connect to peers fast enough. After you restart node, it will go to using 200MB of ram and it will be in best condition for validation.
Please don't use VPS's with Windows and 2GB of ram, you will maybe pass one validation, but will fail next for sure. For VPS with Windows, 4GB is minimum for normal funcioning for you to be safe and not fail validation.

I have talked to many people who think it is better to have three nodes with a bad score (and to participate in mining) than one with a good one. Obviously, I do not support them and therefore, I have only one node.

Okay, maybe this is not half of the total. Quarter.

This is all really interesting, but what about sharding? When will it be implemented?

Because on the last validation there were some people who just couldn't start their session. The validation started without them. And their nodes were synced. So it is obvious that there are some technical issues like an network congestion. Sharding seems to be the right solution for such problems.

really very useful and informative article, I think many people should read it, now we are waiting for the implementation and launch of oracles in the Idena blockchain 

This is a great article like all articles written by Gigamesh of the Dailychain!

yes maybe people just think the problem can't be solved, just look at ETH also BTC with high fees has yet to find a way to solve it, no blockchain project is perfect, but we have a strong community and quite a lot of active nodes now, looking at the problem yesterday hopefully everything will be safer now, it needs a lot of real people in the future

I have read this and it seems that the writing is easy to understand by readers, I like to see every article on their site

Great article

https://thedailychain.com/idena-and-the-oracle-problem/

No... we can't say that for sure because IDENA economy rewards you for high score which is impossible to get validating 2 nodes. It's better to have 1 good node than 2 shitty with high risk of failing validation on one of them. Majority of people that i've spoke has 1 node per 1 person. Some of them have few nodes but each of them is being validated by real life person (f.e friend/family member)

We will see after validation ceremony. From what i've seen this detected farm is far less than 700 nodes (more like 400-500) but it can be not the only one.

What really happend (by @ozh_v):

https://t.me/idena_trading/31585

We can say for sure that real people in the project are about two times less than active nodes now. As long as it is possible to have two nodes for one person, nothing will change.

How many nodes are currently running right now?
I mean REAL nodes

Yeah. That's great that network become more and more secure, and the most critical code vulnerabilities are being fixed now - while the network is still small and not so popular.

I'm not sure, I was just reposting. Next time I will be more carefull what I repost and to check things out myself.
Note to self, never trust anyone else.
