• increases the cost of opcode SLOAD from 200 to 800 gas
• increases the cost of BALANCE and EXTCODEHASH from 400 to 700 gas
• adds a new opcode SELFBALANCE with cost 5.

Today (April 16th 2019 at noon) the first major clues to discover key #1 was set to be released in a few cities. A QR code with the words 'orbital' were found at these locations and looked like this: (https://imgur.com/a/6rNmz7T). If you read the QR code with your phone you will be directed to this url: https://satoshistreasure.xyz/k1

At this URL you are prompted to input a passphrase to decrypt the first shard. An obvious first guess was to try the word 'orbital' from the QR code. Not suprisingly this worked! This reveals a congratulations page and presents the first key shard:

ST-0001-a36e904f9431ff6b18079881a20af2b3403b86b4a6bace5f3a6a47e945b95cce937c415bedaad6c86bb86b59f0b1d137442537a8.

Now, we were supposed to wait until April 17th to get clues from the other cities for keys #2 and #3 but that wouldn't stop me from digging around with all the new information we had. All that time "playing" notpron (http://notpron.org/notpron/) years ago was going to help me here.

The first thing I noticed was

from blockchain import blockexplorer
from difflib import SequenceMatcher

def similar(a, b):
    return SequenceMatcher(None, a, b).ratio()

def compare (forked_shitcoin_hashes):
    winner = None
    shitcoin_race_winner = 0

* @title Metamorphic Contract
* @author 0age, derived from cloner contract by @mhswende
* @notice This contract will create a metamorphic contract, or an upgradeable
* contract that does not rely on a transparent proxy, when deployed using
* CREATE2. It expects the deployer to provide a getImplementation() function
* that will return an implementation address, which it will then clone and
* deploy. Unlike with upgradeable transparent proxies, the state of a
* metamorphic contract will be wiped clean with each upgrade. With great power
* comes great responsibility - implement appropriate controls and educate the
* users of your contract if it will be interacted with!

Price toots

Some people really don't want to hear about the price! But this is other people's favorite topic. If you adhear to the following two rules whenever talking about price, or something related to the price like altcoin prices, we should all be able to continue interacting about our common interests in Bitcoin:

1. Use a Content Warning (the CW in the Mastodon user interface) to allow people to opt-into seeing your price-related information and images. Note that replies to CW-content are also automatically wrapped in the same CW.
