Star Wars quote etched into eternity
Hey, just found this from 2014. Someone transcribed the Star Wars opening scene into a series of Bitcoin addresses. Too bad the addresses aren't spendable :(
The quote is from this: Youtube - Star Wars (1977) - Original Theatrical Crawl
In block 448064, a single transaction was included, whose output addresses were carefully constructed to read like a love letter to a Ms. Dover.
Additionally, the amounts of bitcoin sent to each line of the letter include a string of numbers from pi, which 'goes on forever'.
Looking backwards, you can see the coins for this transaction come from a vanity address '1DannyDnA68LfEpEX1Ek7APzLBzJqgUgWJ' only 2 days before the empty love letter block was mined, meaning the creator of this letter [...]
The first bitcoin faucet from Gavin Andresen, paying 5BTC/day in 2011!
For my first Bitcoin coding project, I decided to do something that sounds really dumb: I created a web site that gives away Bitcoins. Five ฿ per customer, first come first served, I've stocked it with ฿1,100 to start.
US Marshals Auctions off 29,658 BTC to Tim Draper in 2014
After the US Marshals collected thousands of bitcoin from Ross Ulbricht and the Silk Road, Tim Draper was happy to purchase 29,658 of them in July of 2014 for an undisclosed price, when publicly Bitcoin was trading for $600 each. Now with a price of $4400 today, Tim could theoretically realize a hefty profit of around $112 million!
The purchase that started it all. This is considered to be the first time bitcoin was exchanged for real world goods, when Laszlo payed 10,000BTC for two delicious pizzas. This cemented one of the earliest known USD exchange rates of $0.0040/BTC.

The largest value transfer on the Blockchain ever: 500,000 BTC worth $1.5m in 2011, and now worth $2.35 billion in 2017.
Google announced an algorithm to break SHA1 that is 10,000x more efficient than brute force, and it was proven by signing a SHA1 protected Bitcoin address containing a 2.48BTC ($2616) bounty.
There are suspicions that it was not actually the Google research team that claimed the bounty, rather it was a third-party that made use of the methods Google announced.
