[ANN][SIC] Sifcoin - inflation fork

[cinnamon_carter]

well, look back in history a bit,
people collected bitcoin when it was worth nothing.....


someone i know told me when it hit $13 it was like hitting the lottery !!

simple inflation coin has only been running a little over a year now, and people have been mining all along

personally i think it a crime it is not traded on every major exchange

but no one cares what i think ......

look at it as an experiment , nothing more,

likely outcome will be no big 'cash out' 

you can tell if you really are into cryptocurrency , bitcoin, or any coin if you are willing to spend time mining it , maintaining it, or even posting about it when everyone else is obsessed with VALUE

true value today in alt coins is mostly created by the developers buying thier own coins back or hyping things up via one method or another or more than one.... and duping others to buying the coins....sad but true.....

simple inflation coin has none of this baggage,  it is what is is - nothing more

the russian devs who put it together really did well, 

the code is not perfect and i will not tell you multiple rounds of hashing are more efficient or even more secure from a cryptography standpoint than a single proof of work algorithm,   

they are less efficient and less secure,  this is a proven fact from several academic papers......

still i learned a lot from the code these guys made, and if they are too busy now or whatever to maintain it, i felt the least i could do out of respect for what SIC made possible on the scene was just do a small update,   and now im probably going to run a node so we have some north american coverage......


here is a linux build if anyone wants one based on my fork of the code ----  generally i recommend everyone compile linux daemons themself however someone got in touch with me and said they were having trouble building it so here she is compiled on ubuntu -- its called bitcoind since they never changed the name but
when you run it create a .sifcoin directory in root and put your sifcoin.conf there

run from command line

sudo ./sifcoind -daemon

commands similar to rpc console  i.e.

sudo ./sifcoind -getinfo

Is there any place that you can use/exchange this coin?  I know there has been lots of voting, but I haven't seen any results. What good is it to accumulate a coin that can't be used anywhere, no matter how great it is?

well, look back in history a bit,

Well, if you consider how many coins there are now, bitcoin almost had it easy. There are so many coins exist today, that even great coins with nice features getting lost and forgotten. However, this is crypto so anything can happen.

difficulty slightly down


here are the nodes my full node is connected to now


sudo ./bitcoind getpeerinfo

well well well....... difficulty now spiking up fast --- 

[cinnamon_carter]

difficulty holding --- network pretty stable

[cinnamon_carter]

difficulty still up and down but never dropping too low,

[gjhiggins]

difficulty still up and down but never dropping too low,

At one point, I hacked up a Python sifcoin-hash module (https://github.com/gjhiggins/sifcoin-hash) to get a Sifcoin version of Abe up and running:

Code:

datadir = [
    {
        "dirname": "/home/gjh/.sifcoin",
        "chain": "SiFcoin",
        "policy": "SiFChain",
        "code3": "SIC",
        "address_version": "\u0010",
        "script_addr_vers": "\u0005",
        "magic": "\u00f2\u00d5\u00d3\u00d8",
        "loader": "blkfile",    # See the comments for default-loader below.
        "conf": "sifcoin.conf"
    }
]

The Abe.Chain.SiFChain subclass is quite straightforward ...

(I continue to run a SiFcoin node but I've migrated away from Abe in favour of ACME, my own (as yet unfinished) lightweight RPC-based blockchain explorer implemented in Python: https://minkiz.co/acme/sic --- it's basic and atm, barely better than the raw JSON but I have plans for it).

Also, fwiw: on a whim, I transcribed the Sifcoin code back into the full commit history, added getnetworkhashps to the API and squeezed a “diffplot” chart on to the overview page:

SIC (Sifcoin)    No block explorer, weak/low hashrate network, etc

cinnamon_carter, please write him, have block explorer, hashrate stable. My english is bad, so I beg you.

[cinnamon_carter]

nice work, i will have to check this out !!

would urge you if you get time to do a git pull to add support to official abe on github

https://github.com/bitcoin-abe/bitcoin-abe

jtobey regularly adds different algorithms....

...
jtobey regularly adds different algorithms....

Regrettably ...

I no longer work with Abe

Cheers

Graham

[cinnamon_carter]

i understand and respect that, good luck with your own python block crawler

eventually when i have time i may add it to abe ,

looks like you have all the right things in there,

you and I appear to be the only two people doing any development (even part time) work on this coin....

Okay, I can do that --- but for a PR to make any sense, sifcoin-hash needs to be available to install from PyPi (which it now is).

TBH, I really doubt whether the PR will ever get merged because it proposes to add a Chain subclass with a known unmanaged dependency (i.e. sifcoin-hash) for which the requirement kicks at runtime and it's a showstopper for what would be reasonably expected to be a supported configuration.

I think this is why most algo-specific Abe variants inhabit their own fork, it allows the maintainer to include the specific supported hash function as a subdir, thus enabling the dependency to be advertised and imposed at install time.

Whatever, the edited bitcoin-abe fork is https://github.com/gjhiggins/bitcoin-abe, PR is https://github.com/bitcoin-abe/bitcoin-abe/pull/155

The supporting sifcoin-hash module is https://github.com/gjhiggins/sifcoin-hash and on PyPi: https://pypi.python.org/pypi/sifcoin-hash/1.0.2

you and I appear to be the only two people doing any development (even part time) work on this coin....

Sifcoin's innovation of using a folklore hash combiner makes it one of the more notable members of the altcoin technical engineering heritage.

Graham

[cinnamon_carter]

Thanks Graham

[cinnamon_carter]

OK a few additional minor updates ---

First I renamed my repository to the name of the coin (I was badly in need of sleep when I did the last update)

It is on github here https://github.com/cinnamoncoin/sifcoin

Changes are outlined here, basically a few cosmetics and I updated the version of level db.

https://github.com/cinnamoncoin/sifcoin/commits/master

The windows-qt release is here on github https://github.com/cinnamoncoin/sifcoin/releases

Finally I contacted Coins-e to see if they would add Simple Inflation Coin to Voting to be added to the exchange.

(Who knows maybe this weekend or sometime soon I will use Graham's contributions to make a full block crawler)

it's running now on a node I made but returns nothing obviously, i now understnad what Graham meant when he said it may be impossible since difining sifcoin_hash is not so straightforward as in other proof of work coins..... I will think it over if i come up with something clever will let you know....

You musta missed the bit:

The supporting sifcoin-hash module is https://github.com/gjhiggins/sifcoin-hash and on PyPi: https://pypi.python.org/pypi/sifcoin-hash/1.0.2

All that's required is:

pip install sifcoin-hash

Abe should then be able to read the Sifcoin blockchain.


Cheers

Graham

[cinnamon_carter]

ok , i only had a few minutes to play with it, going to try a fresh install next time out.... thanks again.... i think i tweaked too many things on this attempt !!!

edit, it now reads the .sifcoin blockchain in my root directory a little bit before throwing all kinds of crazy errors ! !!

Winning is sent after the first confirmation of the received transaction.
To determine win amount script uses the first symbol of sha256('txid'+'secret'); (in hexadecimal, '0'=0.01, '1'=0.1, '2'=0.2, ..., 'a'=1.1, 'b'=1.2, 'c'=1.5, 'd'=1.8, 'e'=2.2, 'f'=3.5). The 'secret' changes once a day (00:00 UTC) and is published in my forum sign.
Script accepts only normal transactions made with the reference wallet.
Bets greater than the maximum are returned minus fee 0.0005 sic.
Bets less than the minimum are equated with donations and are non-refundable.
The minimum win is 0.01 sic.
The maximum prize is limited by the size of the pot.
