This block crashes many web-based blockchain browsers, including the linked one. So the relevant information is: 1) mined by Chinese pool f2pool 2) contains only 2 transactions: coinbase and single regular one 3) the regular one has no fees, but 5569 inputs and 1 one output. It appears to mop up dust outputs for a total of BTC0.05569000 4) it probably should get a medal for UTxO minification 5) the total block size is 999,923 bytes Edit: Nothing to add, just quoting the reply from Danny in case he changes it: This block crashes many web-based blockchain browsers, including the linked one.
So the relevant information is:
1) mined by Chinese pool f2pool 2) contains only 2 transactions: coinbase and single regular one 3) the regular one has no fees, but 5569 inputs and 1 one output. It appears to mop up dust outputs for a total of BTC0.05569000 4) it probably should get a medal for UTxO minification 5) the total block size is 999,923 bytes
The BTC0.05569000 total is paid to the same address as the coinbase transaction. As such, it would appear that the transaction was built by the pool, and that the entire transaction is fees.

So just getting all of someones satoshis together takes up an entire block and crashes block explorers? Why is it being marked as a double spend by blockchain.info?
Seems weird to me, with stress tests and forks recently there have been a few mishaps in the last few days, this seems like another.

Now that you posted a link it got jinxed and crashes/hangs too. Kinda cool way to show the weakness of the "web-based services" paradigm: they can't tell the sudden spike of popularity from a garden-variety DDoS. And all this added JavaScript sauce, it could really serve as an example how not to design UI widget architectures.

In case, it is crashing at your end, here is a list of alternatives...

OK, there are 330k such outputs in blockchain now One block can reduce this number by 5569 So we need 60 blocks in a row filled by 1 tx just to eliminate these spam outputs from a blockchain ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) By the way, bitcoin has not yet died even after three months of your death prediction. I was wrong. It will die soon.

I dont think, you have read your tarrot cards properly this time as well. Here is something I am copying from elsewhere... Previous Scenario :- 2012 end: Block reward halving 2013 beginning: Hard Fork 2013 mid: Cyprus crisis 2013 end: Bitcoin reached ATH Current Scenario :- 2015 mid: Greece crisis 2016 beginning: Hard Fork 2016 mid: Block reward halving 2016 end: ? ? ? You might like to place a bet on your prediction on bitbet.us as well ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

The crash/hang is actually a symptom of the site activating its DDoS defenses. If you are on an ISP with few bitcoiners the DDoS defenders are unlikely to activate the throttle/reduction and other defenses. You may be also accessing that site during the time when most of the people are asleep in your area. Thanks for the alternate links, but please be aware of the above issues when posting easily clickable links. I have a proxy/vpn on the opposite side of the Globe, that does succeed loading that page.

Wouldn't these spamtransactions be lost after some time when no miner includes them in a block?
I know that this would mean that the miner had to keep all transactions in the RAM but i think it's better to adjus the RAM instead giving in to spam.
