41  Bitcoin / Bitcoin Discussion / Re: Idea for helping Venezuela using Bitcoin on: December 18, 2016, 07:21:19 PM
Does this sound like a good idea? Would you donate? Does anyone know of any trustworthy Venezuelans who would be willing to work on this?
I wonder if any Venezuelan is actually reading this to provide their side of the story...
42  Economy / Gambling discussion / Re: Which gambling sites have 0% house edge? on: December 18, 2016, 02:02:27 PM
https://www.Chain-Bet.com has 0% house edge.

Is the owner of this site is still sane?, because this is really insane having a gambling site that has 0% house edge, lol, just saying. I bet that this person is a very rich one because he is just giving his money by setting his gambling site to 0% house edge so whoever plays on his gambling site would never lose, the players would just keep on winning until they are tired of winning.

0% house edge does not guarantee a win. But it increases your chance to win.

To be brief, 1% more chance to win than a site with 1% house edge. Smiley

I think we can let this thread dies a natural death since we are approaching 6 months after the halving, and difficulty is more than 286 Billion.

Crossed 300 billion today...

45  Bitcoin / Development & Technical Discussion / Re: Can an attacker flood mempool using transaction locktime? on: December 15, 2016, 03:56:12 PM
So, locktime has a max limit as well?
Not in the sense that you are thinking about. There is a limit of 4294967296 seconds past the epoch since the nlocktime field is only 32 bits.
Ok.

Could u plz point me to the relevant part of the code in Github, where it is written that Tx having locktime higher than a certain difference between block height will be rejected?
That's not how it works. Any transaction that has nLocktime set is considered non-final and thus rejected by nodes. This happens if the locktime is a few days away, or a few years.
So, only Tx with nLocktime of few hour is kept in mempool? If that is the case, then there must be a check in the code that filter Tx with nLocktime higher than a few hour. No?
46  Bitcoin / Development & Technical Discussion / Re: Can an attacker flood mempool using transaction locktime? on: December 15, 2016, 03:20:34 PM

Quote
so a locktime transaction can be added to the block chain up to two hours before its time lock officially expires.

nlocktime is not an issue. nodes will just reject and not relay transactions if the nlocktime is a year away.

So, locktime has a max limit as well? Could u plz point me to the relevant part of the code in Github, where it is written that Tx having locktime higher than a certain difference between block height will be rejected?
47  Bitcoin / Development & Technical Discussion / Can an attacker flood mempool using transaction locktime? on: December 14, 2016, 09:50:35 PM
If an attackers broadcast a bunch of Tx with the following criteria...

a. high Tx fee

b. total size of the bunch of Tx higher than mempool capacity

c. transaction locktime of a block, which is supposed to be mined after one year


Then which of the following will happen?

i. nodes will crash

ii. Tx fee required for new Tx to be in mempool will be higher than what is set by the attacker

iii. nodes will remove the bunch of Tx with transaction locktime of far future block


p.s. If u dont know about transaction locktime, please refer to - https://bitcoin.org/en/developer-guide#locktime-and-sequence-number
48  Bitcoin / Development & Technical Discussion / Re: How did Bitcoin "start"? on: December 13, 2016, 03:53:46 PM
My question is, who started the first node of the network, and how?

Satoshi started by mining the Genesis block - https://btc.com/000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f
49  Bitcoin / Development & Technical Discussion / Re: Is there any max limit of a mempool? on: December 13, 2016, 03:46:17 PM
Bitcoin Core has a default max mempool of 300 MB, after which point it will start kicking transactions and increasing the minimum fee to get accepted.

Thanks a Lot. Could u plz point me to the relevant part of the code in Github?

Well you told us how to sign a message .. But please tell me why it is needed to sign a message. What is it used for and why to sign a message?? Huh

Primarily it is used to prove ownership of a bitcoin address.

How do I use keybase.io? I tried to search it but its really confusing and cant get what I want to know can anyone help me or just simplify it to me or anything thanks

Keybase.io allows u to generate your own PGP key and sign any message with that. Which part appears difficult to u?
53  Bitcoin / Development & Technical Discussion / Is there any max limit of a mempool? on: December 13, 2016, 03:08:30 PM
I mean 32mb/64mb/128mb beyond which it will crash or wont relay new Tx or remove old Tx to accept new one. If there is no such fixed size, I'd like to know the max limit of an average node...
54  Other / Beginners & Help / Re: what is stopping miners from making empty or near empty blocks on: December 13, 2016, 02:37:05 PM
This Q has been discussed many times before...

but what is stopping a miner from setting some rules for the transactions they receive like a very high minimal fee/kb and only create empty blocks?
No. There is no network rule to stop miners from doing this.

is there any way to prevent this if some day a bad miner decided to do this for any reason?
They are not economically incentivized to do this. More Tx = More fees. If a pool keep creating blocks without high fee Tx, miners will abandon it and move to another pool for their own benefit.

56  Economy / Micro Earnings / Re: Which web hosting do you use to host your faucet? on: December 06, 2016, 07:53:56 PM
My advice go to namecheap they have best services and accept Bitcoin as wall.

NameCheap they are the best not only that but you get a free domain with the order YourDomain.website it also accepts bitcoin

Nacheap.com always best, because they have unlimited bandwidth for any packages. And I am selling one namecheap pack with cheaper rate, check here: https://bitcointalk.org/index.php?topic=1704764.0

I do agree that NameCheap is great for domains and they do accept bitcoin as well. But, I think, one should not keep all his eggs in the same basket. Hence, hosting should be from elsewhere.

If my potential activity is in the range of Legendary, then is there any way to confirm whether I will be a real Legendary once my post count equals my potential activity?
58  Bitcoin / Bitcoin Discussion / Re: NetBet Becomes the UK's First Licensed Gambling Site To Accept Bitcoin on: November 20, 2016, 06:53:42 PM
Seriously ? Woo, that's very awesome news ! I've always been attracted by NetBet and its included live-streaming service.
Be careful. AFAIK, they dont allow bitcoin withdrawal yet...
59  Bitcoin / Bitcoin Discussion / Re: How long it might take to confirm the following transactions? on: October 04, 2016, 09:49:59 PM
Tx2, Tx3 & Tx4 have already been confirmed. Tx1 is still pending. The funny thing is that, while u and many others are waiting for their Tx to get confirmed, Antpool mined a 2.1 Kb block with just 7 Tx in it.

If anyone of you needs to quickly sign a message without having the core client handy, feel free to use https://ordinarydude.github.io/offline-bitcoin-signer/.
The source code can be found at: https://github.com/OrdinaryDude/offline-bitcoin-signer
Fantastic work! It would be great if u added a JS based signed message verifier as well.
