leveldb would not improve the start-up time by much, as there are some more PoS-related checks and also the scrypt Nfactor a major role in load times (and with so many blocks it gets even worse).

yeah, the geolocation data was on my old site - though afaik it was quite inaccurate (a LONG delay before an inactive address was removed from the list - so it was a bit inflated). i could make a more accurate version of that from the dnsseed server data (currently ~400 nodes, just 35 with over 10% uptime over last 30 days - so the network isn't that big).

no opinion on the qt wallet transparency here Tongue

aliases - i'd rather not do that. even firstbits seemed like a dumb idea to me. i can guarantee it'll end up like the coinbase's aliases (at least i think it was coinbase) - a fake sean's outpost charity alias registered within minutes and "the ceo of bitcoin", to name a few Cheesy

what i'd like to see is people swithing from full qt wallet to thin clients (instant start-up, negligible storage requirements, not so much cpu-intensive - so it can run on your smartphone without draining the battery in seconds). however, that would require a PoS minting capability built into such clients - which is not an easy task, but certainly doable. just my 2 yacs

With many full nodes that accept incoming connections some cool "anon" features can be done. Not a single altcoin yet improved a way nodes connect and reconnect over time which is what makes networks an easy target for signal inteligence and especially traffic analysis.

imo the node "buckets" and overall connection policy in bitcoin and derivatives in quite good and i don't see anything obvious to improve there. traffic analysis? there's no encryption whatsoever, so i don't see the point there. same with sigint. also, all the *coin networks have a unique identification "magic" so you can eg. easily block all bitcoin traffic with a simple deep packet inspection.

The original reason for it is obsolete right?
Yes, it is.

Groko's been doing some work on the POS miner through the YACoin client.  Looks like he found a world around to some of the long-term concerns.  I thought I would share the link here to increase awareness.  I believe he recently made a pull request to have this items added to the sourcecode.

http://yacointalk.grokonet.com/t/pos-mining-performance-boost/67

More excellent additions by Groko! Well need some community consensus on this, so everyone that can, please provide your opinion.

Still looking for an opinion for some of the bigger holders and old timers in the community.  YAC doesn't mix very well with dictator Wink
PoS doesn't secure the network now anyway, so I'd go with the more user-friendly option and that's not splitting the stake (although it's beyond me why all the people want it to be this way).

wasn't my wiki

YACoin is on the list, but I need info.

What is the total supply? That is blank in first post.

What exactly is the PoW algo? One part says Scrypt-N SHA-3, another says just Scrypt-N and in the next sentence talks about SHA-3 Keccak. Finally the miner uses Scrypt-chacha. I know the SHA-3 winner is Keccak but how does it fit into YACoin?

See this for PoW algorithm:
http://forum.yacoin.org/index.php?topic=322.msg1495#msg1495

...


According to above post post, the library is Scrypt Jane and Scrypt Chacha is one of the mix functions. The hash is Scrypt-Keccak512 with N increasing over time

I will call it whatever you want, but I think Scrypt Jane or ChaCha are incorrect.

call it scrypt-yac, it's got its own Nfactor schedule anyway

Regarding the total supply - this is from sairon :

Quote from: sairon link=http://forum.yacoin.org/index.php?topic=514.msg2282#msg2282
That's theoretically unlimited capped at 2,000,000,000 coins. However, transaction fees are destroyed instead of distributed to miners and proof-of-work block reward decreases with increasing difficulty. So IMHO it will find its equilibrium somewhere lower.


not true, there's no coin supply limit. the 2 bil limitation applies only to a single input.
that said, the equilibrium part still holds. it all depends on how the tx volume, pow supply and pos supply balance out.

I am going to use one word to describe coin supply. Would you like infinite or unlimited?
unlimited describes it much better than infinite

BTW well done! YACoin has now surpassed bitcoin in marketcap by more than 10 fold! lol wth...
lmao, an unintended consequence of joe switching the dns of explorer.yacoin.org to the new server and me implementing an (almost Cheesy) compatible api on it - though instead of a decimal number it lists the coin supply in satoshis Grin

anyway, hopefully this gets us some nice publicity and maybe even increase the exchange rate a bit Tongue

R7 240 4GB = 984 H/s
You're a little low, may want to work on settings - try a lower LG or increase frequencies.  You're leaving hashpower on the table...

new snapshot with most electrum plugins fixed/modified to work with yac is up Cool

list of available plugins:
* yacoin exchange rates (so far just from cryptsy api and only to btc)
* label sync
* point of sale
* qr scans
* virtual keyboard

disabled plugins:
* aliases (bitcoin electrum ships with this disabled anyway)
* coinbase buyback (for obvious reason)

teaser screenshot from windoze (running raw python scripts, still haven't figured out the py2exe setup script)

fresh yacoin electrum distribution archives (tgz and zip) up in my dropbox, grab them while they're hot (and don't forget to post some feedback!)

note for windows users: you need to know how to run python scripts if you wanna try this Tongue

http://explore.grokonet.com/ Is there any API for this block explorer?
Official explorer has been dead for ages
well, technically it's dead only since today. the motivation behind this decision is:
* it was running too damn slow to be of any use anyway
* the benefits of running that server didn't justify the cost (over $20/mo for something that's constantly moving through the thin line called "working/broken")
* some of the stat-generating cron jobs actually didn't even have a chance to complete as they were getting killed due to an out-of-memory condition

as a replacement, i'm running a (much cheaper but working and fast) new explorer at http://yacoin.unsha.net

Hello Sairon & anyone else suffering the "ISP blues",

Could you use this Linux ISP?
http://inxtracking01.inx1and1.de/tracking?i1005q00bdrfqbpn55000d0000000000000000cx6wb0i6&kwk=6854016

Yes $0.99 for the first year! 
Unlimited data transfer etc. etc. Or maybe the $5.99/month package?

Just use that link if you sign up, it gets me a "smidge" off my websites(shameless plug) Cheesy

Ron
yeah, but i need a vps, not webhosting Smiley
actually, their vps prices are a bit higher than what i pay currently at chunkhost

...
PS: i really tried to make a windows executable with py2exe, but there's no fucking way i'm gonna get that stupid m$ visual shit to work (needed to compile yac_scrypt)...
...
MSVS can be like a fickle mistress.  You treat her wrong and she will give you hell.  You treat her right and she will make you very happy Smiley
What are you trying to do with MSVS?  What is yac_scrypt?  You did see my videos on building all the libraries for Bitcoin, YACoin, etc.  and my video on my YACoin changes using MSVS?

Ron

i was referring to yacoin_scrypt python module (which itself is written in c). finally managed to compile it with mingw (the time i could've saved by trying it this way first... gah), so it's ok now.

here's a beta version of electrum client for yac. most checks are skipped for now and not all block hashes are checked for performance reasons (sometimes it seems like a bad thing that scrypt-chacha is so slow). first you need to compile and install the yac_scrypt python lib (if you use p2pool or something you probably already have it installed).

PS: i really tried to make a windows executable with py2exe, but there's no fucking way i'm gonna get that stupid m$ visual shit to work (needed to compile yac_scrypt)...

PPS: no idea how to get the lib working on android so far, so don't ask me

13  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] YACoin ongoing development on: June 01, 2014, 08:17:13 PM
Maybe I should be more precise. Thats an example of use of MPOS api:
http://maxcoin.miningpoolhub.com/index.php?page=api&action=getdifficulty&api_key=example_id&id=7067

Edit: I know that it may not be possible to get data straight from url, just wanted to make sure Wink
yeah, it's not possible. you need to make a post request

* sairon adds REST API to TODO list
14  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] YACoin ongoing development on: June 01, 2014, 06:46:40 PM
here's a beta version of the API reference, feel free to make a pull request Smiley
https://github.com/saironiq/electrum-server/blob/master/README-API.md

also, i'm open to suggestions for new api methods if you need them.

you can test the API at electrum.unsha.net
ports: 50001 (tcp), 50002 (ssl), 8081 (http), 8082 (https)
and the brand new webocket interfaces: 8008 (websocket), 8009 (ssl websocket)

i wanna see some great new services built upon this api! Tongue

you can run your own electrum server (clone at https://github.com/saironiq/electrum-server), however, you need to apply this patch to yacoind first: https://github.com/saironiq/yacoin/commit/801d5756072bbe087cf009ad8490aff17aeb664f

Can you post an example of http request to "getdifficulty"?. I cant seem to work it out.
it's json-rpc. simply make a get or post request with data set to the actual request

eg. with curl:

Code:
curl -d '{"method": "blockchain.mempool.get", "id": 0, "params": []}' -H 'Cookie: SESSION=YOU-GET-THIS-FROM-SERVER-AFTER-FIRST-REQUEST' electrum.unsha.net:8081

the session cookie is quite important as the server will not neccessarily return the answer right away. if it doesn't, you just send an empty message ("[]" is a good example, an empty array) and the server sends you all the queued responses.

it sure looks nice, but adapting it for yac seems kinda challenging given most things are hardcoded in multiple places. also, i don't like the prospect of running Yet Another leveldb alongside the electrum's with essentially the same data. (and neither do i like node.js Tongue)
Hi Sairon

levelDB shouldn't phase you.  Have you seen my video on building a static leveldb library, at
https://www.youtube.com/watch?v=x1U1cBx6Ub0? Grin  Should be easy to port back to gcc.  Bitcoin has been doing it since ~0.8.0  YACoins data only seems to be about 300MB / year?

And do you know what a famous pundit said about scriptaculous & other javascript "frameworks"?  I was at a NFJS conference and the (anonymous speaker) said they appear to him to be a "steaming pile of code" Shocked Grin

Ron
nah, leveldb is cool, the problem is it just seems wrong to store the same data twice. either way, i use it from python, not c/c++ Tongue

but did the speaker survive?
18  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] YACoin ongoing development on: May 29, 2014, 08:48:58 PM
Wink
so, i'm writing the electrum-based block explorer myself now, mostly out of boredom (and also due to lack of volunteers).
the code is a major mess and still WIP (eg. no search box and no address handling so far), so consider this an early alpha preview.

http://yacoin.unsha.net/

PS: i know that i suck hard at writing javascript

That looks real nice! I throw my hat into the battle of the block explorers with my brand new super fast address balance
look up with transactions:

http://explore.grokonet.com
Hi Groko

It's nice to see someone who can still write HTML Wink  One can easily add a "smidge" of Javascript to that html that would "ask" for a new block every ~30 seconds or ~minute or what ever time period you like.  It could even be "done with AJAX". 

Where is the server getting its data from, might I ask?  Is it an "ABE" YACoin talking to a yacoin daemon on the server?

Ron
I've done something similar with my prototype explorer, though it's using websockets instead of polling the server every x seconds, which is imo cool. The browser support still sucks, however (and my html&js skills, too, for that matter Grin - guess i'll just focus on finishing the damn electrum client finally in my next coding session).

just a reminder: i'm still looking for buzzword javascript web dev to do a simple front-end for a block explorer. (jquery, angular.js, twitter bootstrap or whatever you prefer; websockets required)

and there i was hoping it would be up & running by the end of the month, silly me Undecided

have you looked into the insight block explorer's
https://github.com/bitpay/insight
it sure looks nice, but adapting it for yac seems kinda challenging given most things are hardcoded in multiple places. also, i don't like the prospect of running Yet Another leveldb alongside the electrum's with essentially the same data. (and neither do i like node.js Tongue)
19  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] YACoin ongoing development on: May 26, 2014, 12:38:34 AM
Yacoin is pretty awesome, the coin parameters and community are brilliant.
It's a shame it isn't more popular.

If only it had launched not as a fork but as a stand-alone coin written from the ground up, it would no doubt be one of the strongest coins.

Like essentially EVERY alt-coin in the world, Yacoin was forked from Bitcoin. However, YAC also ORIGINATED the scrypt-N (sometimes known as scrypt-jane) concept for the alt coin community as well. Every scrypt-N coin is forked from YAC.

There are probably ~10 - 15 alt coins ever released that brought something new to the table and Yacoin is one of them. That leads me to believe that our problem is lack of marketing, and also lack of participating in the nefarious plots that some other coins employ such as numerous fake accounts on BCT promoting (pumping) the coin between them, or doing the same thing on the exchanges (dumping). We'll continue to work on innovation and eventually the price will have to reflect that.
Pretty much...
Also, I suspect that the YAC community is incredibly small so far compared to other *coins.
20  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN][YAC] YACoin ongoing development on: May 23, 2014, 03:58:44 PM
Thanks to Cypherious and YAChoarder on the yacoin forums, the YAC multipool bounty is now up to 100,000 YAC! At current prices, when converted, that is about $500 USD.

I received a PM that this may have been completed!
