Planing a bitcoin-project - looking for team-member
by
tonytumble
on 22/06/2016, 06:40:44 UTC
Hi there,

i would describe myself an capable, talented back- and frontend developer with about 15 years of experience in various industrial and financial IT-fields. I am currently working at my PhD and have some spare time left. The last months i ve been following BTC and its economic as well as social "rise" very close. And tbh, i ve never spent so much attention to any project like this. The potential is enourmous and i think most of the users just don't realize it.

So let me come to the point. I ve been planing two very interesting projects and now look for team-members. As mentioned i am a good dev and sec-analyst, but poor in marketing, designing and soft-skills like communication and stuff. Its just not my business. So if you feel like you could be an enrichment for this project please contact me. If you have questions just ask publicly.

2 - 3 people will get the opportunity to join.

Every team-member will get a share in this project. I can assure you that it will be profitable within couple of weeks after launching. More details will be discussed personally.

greetings,
tony

As mentioned on the mailing list last month ( https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2016-May/012743.html ), there are notes and a transcript available from a few conversations between some Bitcoin Core developers.

Transcript/notes: https://bitcoincore.org/logs/2016-05-zurich-meeting-notes.html

Summary: https://bitcoincore.org/en/meetings/2016/05/20/

This transcript covers topics such as:

* segregated witness (segwit)
* error correcting codes for future address types
* encryption for the p2p network protocol
* compact block relay
* Schnorr signatures
* signature aggregation
* networking library
* encrypted transactions / committed transactions
* UTXO commitments
* merkleized abstract syntax trees (MASTs)
* mutation testing
* key derivation scheme proposal for Lightning Network
* child-pays-for-parent (CPFP)

thanks for sharing. indeed some interesting points in the transcript such as Schnorr sig integration. following this topic for the last weeks.. have you been on the zurich-meeting?

Re: libsecp256k1 schnorr sigs - how to determine the number of signers
by
tonytumble
on 08/06/2016, 22:46:07 UTC
I have been experimenting with the schnorr combined signatures and I cant figure out how to directly determine the number of signers.

From what I am seeing, the combined pubkey will say any combined pubkey with any subset of signers is valid.

I dont see a clean way to get a specific threshold validation. Is the process to iterate through all the pubkeys from each signer to see which ones validate against the combined signature? Otherwise it seems that some sort of combinatorial explosion of combined pubkey needs to be made to find the exact set of signers.

but I only need the number of signers, not the exact ones, so I am hoping there is a simple way

James

i would determine it by iterating through every users pubkey and validating them against the sig. I don"t think there is a easier way as its not known how many users combined their sigs into the merged "unified signature" which from my understanding does not reveal who nor how many people signed. but with their pubkeys you could validate their participation incrementaly.

Re: Bitcoin price will reach $4000 after halving ?
by

Do you all actually think that the coin will rise so much to the 4000 each i dont think that can be true. there is allot going on with the coin after the halving but i think that only causes the mining procedure and not the price.

halving will enforce a price-rise. no question about that. the supply/demand balance will be affected by halving. if the offer is shrinking, then the price will rise. as said before. this may only be temporarily. but we will see some crazy price-movements.

agree on this talk. spoetnik has style..  and regarding his arguments regarding the evolution of the cryptocurrency-scence. i also have to (sadly) agree that its mostly right. 80% or more of the crypto-scence turned into a pyramid like scheme the last 2-3 years... anybody with IQ > 80 know where this will end. or how it will end.


As someone that has been here on the Altcoin Section scene from day one...

Nothing has changed, not at all

Just more coins and more scammers.

This section never was "technologist" LOL


If I was to ever have a successor

No finer than Spoetnik!


~BCX~



you said it: nothing has "changed". it just got worser than it already was. But from my pov, back in 2013 it was kind of livable... or lets put it like that: it was "better"...

Re: My whole life is a lie..

For a big time I thought that one satoshi equals to 0.000000001 BTCitcoins. But, I missed for a whole decimal. So, I thought that 100k satoshi equals to 0.00001 not 0.0001 Bitcoins. I choose 100k for an example because I'm earning that much daily with a faucet. It is enough for me since my earning are low anyway. So ai thought it was too pow for me, but it's not.

A big miss from me, I was in this lie for 3 months and just found out today. I am blind...

try to offer any kind of skill as a service in here. Writing articles, designing logos, artwork, coding, webdesign, ecetera. I am sure you will be able to earn much more then with the faucets. I never invested time into faucets.

bitcoin is too volatile to keep a stable price for a longterm period. It will rise for sure with the halving, this stage (of pricegrow) already started +1 months ago. I predict a pricerange of 800 - 1200 USD during couple months after halving. But not really sure how long this will last. We will see a lot pump and even more dumps.. The big thing is, this is all about math. But only few understand this.. One day +21 mio people will be aware of bitcoin and have interest of owning at least ONE of this unit. A whole BTC unit. this will be the time when btc will reach values we never dreamed of. A lot of the people here are not interested in bitcoin becoming mainstream alternative payment system to be used instead of fiat-currency. Most are here for a "fast buck" and forget about the real "value" of this project. well anyway - lets see what happens.

Re: implement Bitcoin Core?s signmessage command
by
tonytumble
on 16/03/2016, 13:52:52 UTC
How do I implement Bitcoin Core?s signmessage command in Java?

In order to get a signature, I used the following code:

ECKey key = ECKey.fromPrivate("morR2S8NfjiphGnGWwXuSXPoW9pRM9Du9h".getBytes());
String signature = key.signMessage(?create 225015613080074076?);

But I got the following exception. I don't know why?

java.lang.ArrayIndexOutOfBoundsException
   at java.lang.System.arraycopy(Native Method)
   at org.spongycastle.crypto.signers.HMacDSAKCalculator.init(HMacDSAKCalculator.java:58)
   at org.spongycastle.crypto.signers.ECDSASigner.generateSignature(ECDSASigner.java:94)
   at org.bitcoinj.core.ECKey.doSign(ECKey.java:629)
   at org.bitcoinj.core.ECKey.sign(ECKey.java:619)
   at org.bitcoinj.core.ECKey.signMessage(ECKey.java:769)
   at org.bitcoinj.core.ECKey.signMessage(ECKey.java:756)
   at com.am.coinspark.service.MessageCreate.getSignature(MessageCreate.java:115)
   at com.am.coinspark.service.MessageCreate.main(MessageCreate.java:94)


follow this instructions: http://bitcoin.stackexchange.com/questions/42245/eckey-ecdsasignature-creation

here is the explicit method description: https://bitcoinj.github.io/javadoc/0.12/org/bitcoinj/core/ECKey.html#signMessage-java.lang.String-

hope it s clear now.

I will go first if you are interested to buy btc for USD through paypal. I have some balance in my paypal. Want to buy directly. Or tell me any exchange where I may buy btc by fiat. My country is not allowed in coinbase

there are many ways to buy bitcoin. check this guide: http://www.coindesk.com/information/how-can-i-buy-bitcoins/

ps. paypal isn't a good option here because you could charge back the money after buying btc from somebody. its not secure for the seller.

Re: RPCAllowIP problems
by
tonytumble
on 06/03/2016, 13:03:44 UTC
When I run the server on localhost and connect to it from localhost it works. However when I add in the proper ip and run it from an external server it gives a connection refused.
Bitcoin.conf contents:
server=1
rpcuser=root
rpcpassword=examplepassword
rpcconnect=123.123.123.123
rpcport=8332
rpcalowip=123.123.123.123 (the ip of the external server).
So what am I doing wrong?

seems you are using bitcoind to connect to 123.123.123.123 and send the commands there.
remove rpcconnect=123.123.123.123. only the rpcallowip tells the bitcoind that the host with this ip
is allowed to connect to your bitcoind. the rpcconnect tells bitcoind to connect to that server and send the commands
there...

Re: Blocksize needs to be increased now.

they should have integrated BIP 101 months ago. Missing this will have bad results on the project BTC. But it will anyway succeed.. I hope the responsible "guys" get banned one day from this project. There was always conflict of interests.. They work for companies which don't want BTC block size to be increased. Sad but true...

i read about bitcoin and joined this forum to get more information. i did not know that there are topics like this.

it looks like this forum allows full freedom of speech/expression/opinion. Or am i wrong?
i think there should be a warning for younger visitors regarding the adult, obscene, disgusting, graphic, gory, disturbing and shocking videos/photos.
