[SKY] Skycoin Launch Announcement

I keep on getting "Requesting DHT peers"

Anyone experiencing the same?

I keep on getting "Requesting DHT peers"

Anyone experiencing the same?

Yes, i had the same thing - my peers.txt file was empty. Probably needs some constant address hardcoded.
I know bitcoin used to tackle this by using IRC in the beginning.

Anyway, I got a list of peers from "cell", pasted it in the file /.skycoin/peers.txt and it works fine now.

The list is here:
http://pastebin.com/H3xPHXuE

Plz update if it works for you.

To the Sky and back SKY interesting journey true the virtual coin...

Thank you, but still the same. I deleted everything inside ".skycoin" folder, except "peers.txt" and "wallets" folder. But no blockchain is being downloaded and the message "Requesting DHT peers" still appears.

Are you in Linux or Windows?
Another user on IRC said he has the same issue and therefore runs skycoin under VM in windows.

Windows. Maybe it's a firewall issue, but I wonder why yesterday everything was running smoothly

...I wonder why yesterday everything was running smoothly

Have you pulled the updates code from the repository?
OP suggested doing it every second day.
Many small changes are added now to correct bugs etc.

That might be it... I used the client from here https://bitcointalk.org/index.php?topic=380441.msg11060146#msg11060146, so I might not have the latest code revisions in it!

Update:

Procrastinating. Getting back to sending out more IPO messages.

There is a huge amount of work queued up now.

Bug Fixes: Networking

Yesterday, as soon as soon people started connecting to network, we found out how unreliable the internet is. People had difficulty connecting to servers. The majority of client did not have open ports so could not accept incoming connections. People had to wait hours for connections and then transactions were not propagating for some users, depending on country.

I disabled DHT and PEX and just hardcoded list of servers and then clients connected within half a second and it worked.

Peer-to-peer appears to work best when there are at least a few fast servers the client is guaranteed to connect to.

- PEX needs to be updated to keep track of which peers allow incoming connections.
- A user should not pass a peers unless they have succeeded at making an incoming connection to that peer
- Only a fraction of the peer list should be passed each request
- Connection attempts should use exponential back-off
- PEX needs to store and save the last time a connection succeeded for that peer
- We need to get UDP+hole punch for next networking refactor

I have a sketch now, of how Skywire will fit into the existing networking refactor.

As soon as the crypto library is ported completely to golang (there is a single C dependency right now), then we will have automatic cross platform builds for all platforms. Right now windows has to be done by hand.

The cross platform build tool fails when there are cgo dependencies.

Hi Skycoin,

Haven't been able to receive the coins you sent yet.

Still can only run the first skycoin-win download which I downloaded quite awhile ago now. Ran it for a few hours but no coins showing in wallet.

The latest download I have, skycoin-win-20150415 starts and shuts down straight away. It just wont work, and as far as I can tell it isn't creating a blockchain file.


Thanks for sending coins, hopefully I can get them into my wallet sooner or later.

I think a new download is needed that doesn't have these problems. If you can show a new link to a new download so I can try it out as soon as its ready.

Thanks again.

In the long term, we need open source CPUs.

Some of the CPUs have microcode backdoors that do not have any authentication on the microcode patches. The most recent ones use an RSA key, but anyone with the RSA key can exploit the CPU. There also appear to be buffer overflow attacks on the microcode update process itself. The security appears to be horrible. The Intel Processors were easier to exploit than AMD. There are more microcode example.

....

Secure and open processor designs also require a secure manufacturing process.  A design given to an ASIC manufacturer could be modified and backdoored before committed to physical chips.  This implies that any open processor design should be simple enough to be easily understood and verified, and the manufacturing process/fab size used should be large enough that it is open to visual inspection of decapped chips using low cost processes that would allow nearly anyone to verify the integrity of the physical device for themselves.

http://travisgoodspeed.blogspot.com/2009/06/cold-labless-hno3-decapping-procedure.html

An open processor running on a closed FPGA would not be enough.  It is not enough to rely on the security of FPGAs as they may be compromised at the manufacturer's level.  Several years ago researchers found a backdoor common to all of a manufacturer's 3rd generation FPGA families, including the military-grade ones:

https://www.schneier.com/blog/archives/2012/05/backdoor_found.html
http://www.cl.cam.ac.uk/~sps32/ches2012-backdoor.pdf

The backdoor allowed an attacker to extract the bitstream configuration from a locked FPGA.  It required physical access as it used undocumented JTAG commands.  The backdoor would allow an attacker who gained physical access to a device to extract the design, modify it, then re-write the modified design back into the device without being detected.

A simple RISC processor design, like those of the more recent work of Niklaus Wirth, may be in order -- with the caveat that the final design be committed to ASIC rather than FPGA.

Hi Skycoin,

How much is actually functional from the Partial Feature List in the OP?
How about setting up a website? Nothing fancy, even a wiki engine would do with perhaps a blog, so the information would be structured. There you could list the working features, roadmap, found bugs, nodes, etc.

I know that you have no time for this but good communication is always of strategic importance. I can devote some time for this, if you're interested.

thanks for processing my payment and sending my SKY, good luck everybody  

[CoinAwesome]

Is SkyCoin actually a thing now? Final blockchain?

[Tobo]

How will the projects like Google's Loon affect Skycoin?

Update:

Processing more receipts. Everyone who sent receipts will eventually get the coins requested.

IPO Support

At least one Chinese user in QQ chat has mentioned they have sent bitcoin and not received coins. The outputs are being double checked to make sure they are created, but if you have any problems, check

http://skycoin-chompyz.c9.io/blockchain/blocks?start=0&end=500
http://skycoin-chompyz.c9.io/outputs

If your coins appear there, but not in client then it means client is having difficult syncing.

If the coins do not appear there, message on Bitmessage and we will check ledger and resend coins

Todo:

The network has been operating for a few weeks now. It is working pretty well, but there are reliability issues over open internet that did not occur in the VPN testing environment.

The two major improvements that are needed are
- queuing pending transactions, ensuring they are executed, blocking wallet from creating new transactions until existing transactions are executed, putting indicator in GUI to allow diagnosis of transactions that fail to propagate
- major refactor of PEX (peer-exchange). Peer-to-peer works perfectly when every client is equal, fast, has reliable network connection, allow incoming connections and same version of software. In real world, we have encountered a bunch of edge cases that require a full refactor of PEX. PEX is the library that manages peer-swarms, exchanges peer introduction and is component for maintaining connectivity in peer-swarms. This is only used in Skycoin Daemon right now, but can be used to build other P2P applications in future.

I remember looking and not buying because the IPO was too low a % of total coins and too complex to buy a couple months ago.

What is the distribution graph for all coins and IPO coin release plan in a nutshell?
