Topic: Bitcoin is not the answer for microtransactions; how to rebroadcast unconfirmed? - page 3. (Read 3936 times)

microtransactions = wait for payment-channels. we are early in the game. be patient.

Indeed, only a few could make it. Most would have this issue.
Who sends $1 often enough to care about it?

I use Bitcoin for any major transaction I want to make and the relevant altcoin for smaller transactions like tipping, so I've never run across this problem.

Dogecoin is where Bitcoin was in 2010. If it sees any success, it will have the same issues.

Can't a miner start earlier with the mining if fewer transactions are included in the block? Otherwise the miner has to wait for transactions to come in, or? Obviously that's not how it works but how is the timing of the next block determined?

EDIT: The miner will of course already have many transactions waiting when the mining of the next block starts. That explains it I think.

The miner decides which transactions to include. Miners will include all transactions with fees, of course. The number of transactions doesn't increase the cost of mining significantly, so most miners are generous and will also include transactions with no fees.

Who then decides how many transactions to include in a block? Can one miner choose to include only one transaction while another miner includes thousands of transactions in the next block?

There was someone yesterday who bought bitcoin from a reseller. The reseller didnt pay a fee, thus it took 5 hours. Its hard to tell how long it takes. Ive seen a week, Ive seen a few hours.


No, the amount of TX in a block does not make the block "longer" in terms of the longest chain. Each block is a single link within the blockchain, no matter how many TX it includes (confirmes). The longest chain part is important when it comes to several blocks beeing broadcasted close after eachother, as franky1 allready explained.

i thought it was the other way round. if 2 miners solve a block. if one block has a transaction that is not in the other block then that extra transaction is orphaned and thus ruining the block.

if only miners all communicated together and agreed to include ALL tx's of a certain timescale. they would all be on the same level. then it would just be purely fastest hasher first.

imagine it that the protocol had it so that whilst miners are mining blockA. they are all receiving transactions ready to build blockB. and there is a unix time limit where the consensus then agrees as the cut off period. this is 10 minutes. so not only will it irradicate orphans. but also help to keep to the 10 minute average, thus keeping difficulty under control.

but no miners would want to do that, would they. agreeing is not in their best interest. competing is.

I don't know the Bitcoin details, but wouldn't miners who included lots of micro transactions produce the longest chains and thereby "win" more often?

Example : With android bitcoin wallet, i can only send the minimal 0,06 mBTC (0,02 Euros).
Fees = 0,10 mBTC ...




What is a "micro-payment" ?

Dogecoin is more suited for microtransactions. And the OP problem is why competition amongst cryptocurrencies is good.

The fees for CC and PayPal are much higher as much as 33% on $1 transaction. Sending $1 by WU isn't even possible but it costs $5 to send $20 (40% in fees).  Not sure why you would think that sending $1 by other means would be cheaper. 

As a heads up future versions of the mainline client will reduce the min fee to relay from 100 bits (.0001 BTC) to 1 bits (.00001 BTC).  Still small txns will never be free.  Low cost yes, but free no.   The fees act as a denial of service prevention mechanism.  


No but the client will probably try to rebroadcast continually.  A miner may include it in a block but it may not.   It is possible to "delete" a txn and eventually other nodes will forget about it so you can create a new txn but I am not familiar with the wallet you are using.

bitcoin is perfect for microtransactions. but the mining pools are messing with the original concept for their own greed. so its human greed to limit bitcoins potential that is at fault.

Bitcoin is not suitable for microtransactions just like $100 bills....use a decent altcoin like LTC or DOGE for that purpose and use BTC for larger payments.

People must understand that BTC is a perfect replacement for wire transfers, not micropayments.

As the value of BTC and the size of the blockchain grows this will get worse - for the USD value of BTC, the non-suitabilibity for small payments will not make much difference, in fact I believe that a huge blockchain spammed with small transactions, is bad for BTC's value

anyone care to try to re-push the tx somehow

it seems that blockchain.info's pushtx no longer functions right. instead of re-transmitting unconfirmed tx's, it is saying it already exists. (which it should only say that AFTER confirmation)

I was under the impression that Bitcoin would be the answer for sending micro payments over the Internet, but that is apparently not the case at all.

With a .0001 BTC required transaction fee for all transactions under .01 BTC, that amounts to a 6% transaction fee (at today's exchange rates) for a $1 USD transaction. And that equates to a 12% fee for a $.50 USD transaction. These fees are significantly higher than credit card fees, Paypal fees, Western Union fees, and even foreign exchange rate fees.

A few days ago, I didn't realize any of this information (i.e. the required fees), so I tried to send $1 worth of BTC to a friend WITHOUT a transaction fee to show him how "amazing" this new technology is. Turns out to be not very amazing at all, because the transaction never confirmed because of the lack of the transaction fee. Worst of all, there seems to be nothing I can do about it... I can't even add the 6% fee to it now, in order to get it confirmed!

I used the BitWallet app on iOS to send the transaction, and the hash of the transaction is: c238d939b330b682abe1c729300636600254c23c67e1eea4e8daa9abc26dd2c5

So now the transaction is in a permanent limbo state that can't be resolved, and I have effectively paid a 100% transaction fee because the money is in limbo.

Is there anything I can do to rebroadcast this transaction with the appropriate fee, so it actually confirms?
