Re: Hoeveel % btc bedraagt jou portefeuille ?

Ik heb al mijn btc ingeruild. Ik zie niet in hoe het kan overleven met de onvoorspelbare transactiekosten door de 1mb bloklimiet. Lightning zie ik het probleem niet oplossen.

Re: What will the world look like in 10 years if Bitcoin succeeds?

I am interested to know also.
Even more, what if bitcoin would be the dominant currency in the future?
How would this work with taking loans for example? Would there be negative interest rates?
What would the investment climate look like?

Het zal niemand ontgaan zijn dat er al een tijdje een hevige discussie woedt tav de max. blocksize.
Ben benieuwd hoe hier de meningen verdeeld zijn.

Okay, thanks for replying.
I don't still get the full gist of this but I guess you will need to fiddle with the actual code to get a total understanding.

The transactions included are determined usually by their priority, which is also determined by the fee. Large transactions are typically high priority as well as transactions with a decent fee. I think the software will pull the transactions with a high enough priority first and include those in the block. Also, part of the block is a thing called the merkle root, which is a hash of all of the transactions included into the block. In order to change the hash in different ways besides the nonce, different transactions will also be included to change the merkle root. Generally, block sizes are determined by how quickly the miners exhaust nonces and how many transactions with decent fees can be stuffed in.

So does the amount of transactions in the block change with each hash attempt with a new nonce?

⭐ Merited by ABCbits (2)

From the whitepaper:

1)
New transactions are broadcast to all nodes.
2)
Each node collects new transactions into a block. 
3)
Each node works on finding a difficult proof-of-work for its block.
4)
When a node finds a proof-of-work, it broadcasts the block to all nodes.

So how does the the miner software work? I reckon transactions are flowing in continuously.
The time needed for the pow and the rate of incoming transactions determines the size of the block?

Re: variance in block times --- std deviation

Cheers for that Danny.

Btw, would a realtime difficulty adjustment be feasable in order to garantee a 10-12 min range for instance ? I mean from a architectual perspective ?

I guess not since it would probably be done already. But it would have advantages I take it.

I have a question complementing this thread.
I have copied a chunk from the whitepaper:

Quote
The average work required is exponential in the number
of zero bits required and can be verified by executing a single hash.
For our timestamp network, we implement the proof-of-work by incrementing a nonce in the
block until a value is found that gives the block's hash the required zero bits

Every 2 weeks difficulty is adjusted to keep the 10 minutes avarage in place, but how can this be garanteed since adding or subtracting a nonce will change the difficulty and thus the average exponentialy.
Is there no risk the average will go from lets say 8 minutes to 16 minutes ?

Thanks for answering.
I will experiment with a few other wallets, I think required confirmations should be adjusted to spending amount.
3 confirmations waiting time can be very long when you are hungry ;-)

wallet software and confirmations

So I have started actually using bitcoins recently, have been a saver/hodler for 2 years.
The take-away express in the Netherlands lets you order food in bitcoin with zero fees (can save you some 10%).
So last time I noticed that my bitcoin mobile wallet (bitwallet) was empty so I bought some 20 euros of bitcoins online.
After the buy, my wallet had me wait for 3 confirmations (ca 30 min) before I could send out 10 euro worth of bitcoins.
I know that the takeway takes 0-conform transactions, or at least I get a sms-confirm directly, so I pressume as much.

So why is my wallet waiting for 3 comfirms on a small amount? Also are there any guidelines wallet-software could/should follow for confirms?
How does this work at the btc protocol? At which point can an output be used as an input ? After how many confirmations of the output ?

He typed the private key into his computer to send some bitcoins out of it and a few hours later the rest of the funds on the paper wallet were stolen.

How is this even possible, the funds belonging to a private key needs to be spend all at once right?

No. You need to "spend" all the funds in each input that you are sending however it is possible to make the chance go back to the address that originaly had the funds as is encouraged by the use of paper wallets.

It would be possible to have multiple inputs to an address and only spend one or some of them.

Thanks for explaining, didn't know.

When reading all this I ask myself how can the average non-technical user ever store bitcoin safely ?
You would almost crawl to the necessity of a trusted party to store your keys.

the only reason banking is as profitable as it is today is because banks are allowed to print fiat money and loan it to people with interest.

They will probably be able to continue to do so for a while.

When Alice buys bitcoins from Bob, fiat moves from Bank A(Alice) to Bank B(Bob), hence there is no loss for the banking system.
In other words banks have nothing to fear from the bitcoin network, right?

Ik heb een eigen php framework gemaakt met een stukje smarty templating geïntegreerd.
Symfony ben ik echter ook in thuis.

Sowieso maak ik alles frontend met bootstrap(3).

Hallo allemaal,

Ik ben net begonnen met mijn eigen bedrijfje www.klik2web.nl.
Als bitcoin enthousiasteling accepteer ik natuurlijk ook bitcoins.

Weet je dus iemand die een nieuwe (responsive) website nodig heeft en graag met bitcoins betaald, laat het weten!
