coinomi is good i agree, but it still requires the separate rpc server & electrum backend per coin. i think what poster is after is a self-contained wallet that can operate on its own.

also coinomi is not without bugs..

What algorithms you mining?

seem to have missed the point of the post fella.
i'll repost and try again.

pchMessageStart[] is the name of the array the bytes are held in.
pchMessage's Bytes or as you prefer 'Magic numbers' are a relatively standard concept of making sure crosstalk doesnt happen between any type of standalone node (Paging Channel Host); this occurs across all other types of networks.

When a host is advertising itself to another host; does it advertise its pchMessageBytes or pchMessageStart(s)? C'mon guys.

Anyway, enough of being an arsehole.
If you want to have a mess around with how the peers talk, checkout https://github.com/sebicas/bitcoin-sniffer.

I've found that some implementations do 'talk' with incorrect pchMessageBytes.. however, some get flatout ignored if the PROTOCOL_VERSION is too low.

Still after a definitive answer, anyone?

Please read, and understand my first post.
A node does not broadcast these bytes; unless another node (running identical netcode) sends these same bytes (and version info) first.
If i connect to an altcoin node on its P2P port, it will sit there and say nothing until a timeout occurs.



just found a random bitcoin node, hit it using telnet/raw (on 8333)... connects, and sits there, til timeout.
does anyone know how to get a given node to voluntarily spit out its pchMessageBytes?


pchMessageStart[0] = 0xf8;
pchMessageStart[1] = 0xb5;
pchMessageStart[2] = 0x03;
pchMessageStart[3] = 0xdf;

yes; a seasoned programmer would instantly know what i'm referring to. bytes, four of them.

Its quite a standard component of every Bitcoin-clone out there (https://github.com/search?q=pchMessageStart&type=Code).

Its 4 bytes that are broadcast in each P2P frame; basically makes sure that only the same type client/peers talk.

it wouldnt be impossible to have one wallet natively store multiple chains under the one hood (not thinwallets with a server backend).

however it would be an absolute b**tard to write; and performance would be lacking,
however; it should be able to utilize the same code for each wallet (depending on algo), as long as separate rules are applies for the intricacies of each currency (block time, block retarget algo, b58enc scheme).

Hi all,

I was reading a while back regarding the way the Bitcoin/Satoshi clients talk to each other; it seems that they first send a version-type packet, and if the other client sends a version that is too low, or with different parameters that do not match (for example pchMessageBytes); the client will not respond whatsoever.

Is there any known way to get a remote node to effectively reveal its unique pchMessageBytes?
Besides bruteforcing/pattern scanning (as there are 256^4 or 4,294,967,296 different combinations).

Please don't reply if its simply 'why do you want to do that'.

Very early preview of the RPC utility which will bolt onto the existing Supercoin client; allowing funds to be send from the old client to the new SupercoinPLUS client. I'm still in awe at the complexity/dodginess of the existing chainswaps that are occuring right now (YoCoin anyone? ).

And yes; it queried the client, polled for the addresses/balances all by itself.

unfortunately 808d won't work with a stratum pool by default; however i had written a drop in 'getblocktemplate' function that allows it to work correctly with python-stratum a little while back (https://github.com/barrystyle/808/commit/ac8f5e1a666c49c09a20fde33286a0e36208ad99 - dev please merge).

last night i had roughly 40-50Th pointed at my own pool, resulting in approximately 209coins in 12 minutes..

Hi all,

Again, running late due to issues getting a SuperCoinPlus master node up (well.. quickly at least).
Will post when I have more news.

jimmie? call me baz...
glad to see that this coin jumped the c-cex 'shark'

Guys,

Im going to make some time this weekend to get the new SuperCoinPlus client out with the crosschain node up and functional; as i feel i owe it to Griffith and the few loyal supporters at least. This will include the side plug-in console for the existing SuperCoin client which will make cross-sends possible and quick.

I spoke with the admin at Alcurex a little while back and he is quite interested in the entire concept; so we will most likely look at moving in that direction in regards to an exchange.

It doesnt have to have a local blockchain, nor does this impede its security.

Electrum/Coinomi can be easily ported to suit any Cryptocurrency; in particular Coinomi can handle multiple cryptocurrencies as long as the chains are hosted alongside given Electrum server.

I think some people are missing the entire point of Bitcoin in this thread alone.

One of the qualities of Bitcoin is the ability for a user to remain anonymous (anyone's basic right) and the paradigm that perhaps one day it could replace the entire global currency system. By dumping it straight back to US Dollars or your local currency; you've put a name to an address, as well as demonstrating that you are not interested in using it for products/services as is.

I've done a fair amount of paid work for Bitcoin and various other cryptocurrencies; either through implementation of services as per client requests, fixing bugs or 'bounties' as well as general 'development work required' type positions.

While not the fault of Bitcoin, it does get rough having worked several weeks in a row on a project, where money does start to get tight and money will not be sent until completion of the work as a whole (as opposed to a general salary job), usually in addition to general day job.

A lot of people have fleeced a lot of people too; which does make companies nervous, but for most of the part i've found businesses and individuals alike to be trustworthy. Most of the time where someone does not have best interests at heart, they will slip up or 'obvious behaviour' will give them up.

Coming from both a computing hardware and programming background, Bitcoin and the various altcoins really scratched an itch that I had for some time; particularly the mining in the early days.

About mid-late 2014 i'd managed to score a nearly new Zeus 28mh for approximately 300 AUD (220 USD) and was quite stoked with services like Nicehash allowing me to hash per share for approximately 0.01-0.015BTC/day. My collection grew to include 8 Gridseed blades, which gradually had chip failures, regulator burnouts and USB controller deaths - although at one point I had a reliable 75mh which was more than enough to mine on my own private pool hosted at my place.

I used to regularly look for the 'forgotten' coins on the exchanges; set up a pool and throw some hashrate against it. One particularly rewarding experience was Batcoin on Cryptsy, having come across it with a stuck difficulty of around 1000 (more than likely due to a highest profitability multi-pool bashing it out relentlessly) which it had been at for several weeks. Set a decent share rate (the Zeus absolutely hums at 4096/62m shares) and walked off. Hopped out of the shower to find the 'new coins/mined' balloon flashing like crazy; and had earnt the equivalent of 4-5LTC due to the elastic-band type reflex of the difficulty retarget snapping back from several weeks of non-movement.

I've come across a lot of disappointed people; particularly those who were into the ideals and community but without the computing experience. Unfortunately it seems that whenever there are a lot of people doing the same thing, following the same advice and HOWTO guides - it doesnt make money and I do not feel sorry for them. Time spent equals gains.

It seems that at times the spirit is still there (whether people are actually serious or not is an entirely different matter) however I've found people also seem to feel that they have a right to 'their money' without a deeper understanding of how it all works (and some relatively serious opposition to learning).

Just because someone set up a pool; it isnt 'their fault' if you don't get your guaranteed rate - and you've no right to complain.. because you can set up your own pool - see where i'm going with this?

The only advice i'd give someone starting today is to ignore the websites that promise a guaranteed return, if something doesn't seem right (or if someone is promising something far too good) then either sit and wait it out - or take an alternative choice.

i'm not advocating gambling; however those that hang around generally find that it evens out over time.. or people leave.

i remember throwing around 11-12LTC into 999dice some time back; late night and nothing else to do, then this happened:

not going to lie, i've bawled like a little girl after losing 2.43BTC ($1,822aud) which i accrued starting from approximately 0.35BTC
i find it hurts the most when it is money directly derived from your income; not just a little bit you made from trading alts etc

yes, i was using it as an example to show that rented hashpower can still find blocks of bitcoin; which bolsters punter's confidence in 8-12ph being more capable of finding a block. this isnt my pool, nor is it an advertisement for it 

if you re-read my post, i've explained myself pretty clearly.

what link are you talking about? my sig? not even related.

what would you guys think regarding a 'pot luck' btc mining pool, that waits until it has accrued 1-2btc (up for discussion), upon correct balance it then hires an appropriate amount of hashrate (8-12ph) and starts mining for a bitcoin block?
entirely possible and not even that difficult.
if a block is procured, the winnings can be split amongst those who contributed to renting the hashpower in the first place.

i still see solo.ckpool.org finding blocks with between 1-3ph a day; would be a neat project and i've already a bitcoind/stratum instance running.
