Star Wars quote etched into eternity

mewald55 - /pages/Interesting

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

The Pineapple Fund. $86+ Million Bitcoin Pledged to Donations From a Anonymous Long-Term Hodler

mewald55 - /pages/Charities -

An earlier adopter of Bitcoin has left their greed behind and has begun anonymously donating over 5000 BTC to various charities they believe in, calling their charity the "Pineapple Fund".

From Pineapplefund.org:

Sometime around the early days of bitcoin, I saw the promise of decentralized money and decided to mine/buy/trade some magical internet tokens. The expectation shattering returns of bitcoin over many years has lead to an amount far more than I can [...]

$65 Million stolen from NiceHash

mewald55 - /pages/Stolen

In December of 2017, Nicehash had 4,736 BTC taken from their wallets. This took place just a few days after they completed maintenance to their API, which possibly opened up a security fault.

The attached address is where the funds moved to during the hack.

The largest transaction fee ever

mewald55 - /pages/BigFees

291.241 BTC was accidentally attached to this transaction in mid 2016, equivalent to $136K then, or $1.2M today.

The mining pool that claimed it, BitClub, offered to refund it if an entity could prove control of the sending address, but after some drama related with mixing services, half of the fee was instead donated to The Bitcoin Foundation.

A collection of some large accidental fees

mewald55 - /pages/BigFees -

A few of the largest accidental fees attached to transactions: 81 BTC, 50 BTC, 30 BTC, 16.95 BTC, 10.7 BTC, 4.6 BTC.

The 50BTC fee mined January 2017 is still an ongoing story... The fee was mined by 1Hash.com, and the creator of the transaction has been desperately trying to contact the mining pool to possibly receive a portion of it back. They have signed a message using the spending address, but there has been no word from 1Hash yet.

When 25,000 BTC get stolen from one person (2011)

mewald55 - /pages/Stolen

Here is the unfortunate story of bitcointalk user 'allinvain', who in 2011 woke up to find 25,000 BTC ($425K then, $120M now) stolen from his PC. Their wallet.dat file was apparently left un-encrypted and vulnerable on a live Linux computer, which a virus or attacker was able to access.

The attacker, however, was kind enough to leave 1720 BTC untouched, which it appears allinvain was able to safely sweep them the next day.

Petya Ransomware collected 4.1 BTC ($17K)

mewald55 - /pages/Stolen -

The Petya ransomware was first seen in 2016, but this new strain in 2017 is one of several ransomwares using NSA's leaked Eternalblue exploit.

This version presented the same Bitcoin address to every victim, which was clearly useless because the ransomware was modified to be unable to un-encypt the files it held hostage. It attacked over 80 companies, mostly in Ukraine and western Europe, most notably Ukraine's Chernobyl nuclear power plant's radiation monitoring system was disabled.

New Features: Privacy oriented address tracking with address+tx labeling.

blockpath - /pages/Blockpath

I've been pushing out features that will help you to manage and track your blockchain activity more easily. No more having your coins randomly scattered between hardware/phone/paper wallets and not knowing their status, here is a dashboard for tracking all of your coins.

After starting an ordinary search, open the "edit search" tab to add multiple addresses/xpubs, label them, and then save your watch-only wallet.

The data can either be saved directly inside your browser, or you can copy the [...]

New Feature: You can now search for a xPub account!

blockpath - /pages/Blockpath

Track the balance of an xPub (or multiple xPubs!!) and graph the connections between the different addresses involved. Try it out with this example xPub:

Current implementation: It searches the '0' key space for receiving addresses with a gap limit of 20, and then joins together the change address "1" keyspace. Address limit is at 50 while we are [...]

The Eternal Love Letter

mewald55 - /pages/Interesting

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!

Gavin:

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

mewald55 - /pages/Interesting -

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 Pizza Purchase

mewald55 - /pages/Interesting -

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.

Google Cracks SHA1

mewald55 - /pages/Interesting -

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.

The transaction that can XSS attack unprepared block explorers

mewald55 - /pages/Interesting

Here is a transaction gmaxwell created that could XSS attack blockchain.info. The transaction's hex string, when decoded, contained example javascript code that could execute in the browsers of users viewing this transaction.

The output script for the 2nd output reads: OPRETURN 3c7363726970743e77696e646f772e616c657274282249662074686973207765726520616e2061637475616c206578706c6f69742c20796f7572206d7977616c6c657420776f756c6420626520656d7074792e22293c2f7363726970743e0a (decoded) [...]
