  • 15/07/2010 Satoshi added the next line of code to the software repository:

static const unsigned int MAX_BLOCK_SIZE = 1000000

The software containing this upgrade was released on July 19 , and the new 1 MB limit came into force in September 7, 2010 at block height 79,400.

  • 4/08/2010 Gavin Andresen posts a message indicating that he has to shutdown the faucet because there is some spanish jerk draining the faucet.
  • 15/08/2010. An overflow bug was exploited to create billions of bitcoin. Block number 74638 included a transaction spending 0.5 btc to 2 addresses each with 92 billion bitcoin (2 to the power of 63 satoshis, that added to 0, as the variable in the C++ code is a 64 bit unsigned integer, so the sum of the outputs was lower than the sum of the inputs). Very soon Jeff Garzik spotted the strange transaction and In a few hours, Satoshi corrected the bug and made a post in with the patch.

Version 0.3.10 patches the block 74638 overflow bug.

  • 16/08/2010 The new release was deployed and a hard fork happened removing that block and extending the chain from the previous one, 74637. We can check the time between those two blocks in any bitcoin explorer and see that it’s 7 hours.
  • 5/12/2010 Satoshi answered a post of a user that wanted to bring Wikileaks to bitcoin given that they had already get our of PayPal and the US government was already trying to make the same with Visa, MasterCard and the most important US banks. Satoshi said:

“No, don’t ‘bring it on.’ The project needs to grow gradually so the software can be strengthened along the way. I make this appeal to WikiLeaks not to try to use bitcoin. Bitcoin is a small beta community in its infancy. You would not stand to get more than pocket change, and the heat you would bring would likely destroy us at this stage.»

  • 10/12/2010 PC World published an article with the title: Could the Wikileaks Scandal Lead to New Virtual Currency?

WikiLeaks has kicked the hornet’s nest, and the swarm is headed towards us.

  • 26/04/2011 Last mail from Satoshi to Gavin Andresen, in which he said:

 I wish you wouldn’t keep talking about me as a mysterious shadowy figure, the press just turns that into a pirate currency angle. Maybe instead make it about the open source project and give more credit to your dev contributors; it helps motivate them.
