Title: Block with only 1 transaction

what is the deal here, no one placed a bitcoin transaction in 10 minutes?  is that why this happened?  cause most blocks have hundreds of transactions..

i laugh at people spending all day looking at transactions.. very boring life. whats next a topic about millions of transactions. then a topic about transactions with only fee's, then a topic about high value single transaction, then a topic about a sing transaction where the fee exceeds the value to destination. then a topic about single transaction to multiple destinations, then a topic about multiple origins to single destination. then a topic about any there boring transaction that is more boring then reading my waffle.

point is dont try to waste time trying to think about the reasons. in a country of 60million people+ you will find times where a single person wins the lottery, or a bunch of them, you will find times that one person protests his rights or thousands of people protest their rights,

in nature all possibilities are possible, so dont sweat the nature of bitcoins. it could be a slowday, it could be a miner that formed a block by ignoring other transactions. either way, life moves on, and so does the blockchain.

have a nice day

Mining a bitcoin block is a lot like guessing random numbers until one is the correct one... this mine just happened to guess correctly rather quickly... seems like within seconds.

The 10 minute thing is just a window of how long the bitcoin network wants these numbers guessed correctly. If miners guess correctly more frequently than 10 minutes.. the bitcoin network raises the difficulty (meaning it presents a much larger # pool to guess from)... in order to slow down the rate of guessing the correct answer...

You don't have to include any transactions, although there are incentives (primarily the transaction fees) for you to do so. Some miners don't include transactions, for one reason or another.

It's also possible that the miner didn't hear of any transactions between the time of the last block and when he found his block.

10 minutes? This block was found 17 seconds after the previous one ::)

hmm- why can't a person simply setup their mining hardware to seek out the 1st transaction and submit it as a complete block with just the 1 trx immediately upon receipt? 

Doesn't probability of finding an accurate block increase substantially as the # of transactions goes down?

Dude, you make me feel bad!! Only thing worse than looking at transactions all days is clicking on a thread about looking at transactions all day. Yeah.

The one TX is only the block subsidy for the miner. There was not actually any TX included in the block.

Miners are not required to include any TX in their blocks, but have an incentive to do so as they get TX fees.

Actually, I too like looking at transactions to try and learn more about what is going on (I have been doing Bitcoin for only a few months).  That includes looking at blockchain.info (http://blockchain.info) transactions.  There are lots of things I do not understand about some types of transactions, yet I want to learn more about how it all works.

In fact, I have been looking for the textbook for "Blockchain Transaction Interpretation 101"...

I see nothing wrong with curiosity and wanting to learn more, especially about using BTC for financial discretion and self-protection.  In fact I believe it is my duty to learn more!

1. Because you still need to find the hash that is below the target.
2. No, the probability of finding a block under the hash is independent of the number of transactions in the block.

Miners can include anywhere from zero transactions up to the block size limit, it is solely up to the miner (or pool) who finds the block.

Yup, there simply doesn't seem to be a new transaction reaching the miner's/pool's mempool at that point. It's pure variance: rare, yet totally 'normal'

Wow look at the blocks with the highest fees on that site...200btc fee? Does that mean that miners have made 250 coins on that single block?

Often you will see this when two blocks are solved directly after one another (within seconds). But as far as I know, a miner does not need to include any transactions from others in a block.

I would like to know if there is any way to know who mined it, i mean if any known player mined it, e.g. GHash.io, BTC Guild, Eligius etc ?

The reward was paid to the address at:
http://www.reddit.com/r/Bitcoin/comments/1extr4/asicminer_mining_address/
I'm guessing the transaction fee was a mistake, or some sort of laundering.
Edit: It was a mistake, and ASICMiner refunded it. (http://www.reddit.com/r/Bitcoin/comments/1lb5my/asicminer_refunds_the_accidental_200_btc/)

So, ASICMiner address = 91.223.77.253

Again, http://www.wolframalpha.com/input/?i=91.223.77.253 => Kiev, Ukraine

Does it mean ASICMiner is mining from Kiev, Ukraine ?

Including more and more transactions usually brings more profit for the miner "from the fees" but originally it's not that required IMO, it must have been hard to spot something like that though

It looks like that someone make a very big mistake when making a TX.

EDIT: Yes, the miner made 200 BTC in TX fees, and received a 25 BTC block subsidy so they earned 225 BTC as the block subsidy had halved by then

Someone already explained that they added that high fee as a mistake and that person who mined it gave it back to its owner, firstly miner had to be so happy but then the person who got it back was happy even more i guess,

No it does not increase the chances of finding a block that has a low enough hash as the number of TX goes down. It will take a little bit more time to broadcast the found block to the network as the block will be larger then it otherwise would be.

Miners have incentives to include TXs in found blocks via TX fees that make up for the larger block size

Transactions are random, sometimes it one block can have tens of transactions, while another can have maybe 0 transaction, I guess it follows the Gassuian's distribution?

Most of blocks have 100s of transactions
