Bitcoin Core for Writcoin™ is derived from Bitcoin Core version 0.11.99. It utilizes features of C++11.

Writcoin™, the protocol wherefor this software is a client, features Bitcoin hard-fork requests such as the exclusive use of both pay-to-script-hash within all (non-data) transaction outputs and the exclusive use of fixed-width, 64-bit unsigned integers in storing block times. Writcoin corrects the dates of its genesis blocks to the start of its current Gregorian calendar month and utilizes a Proof-of-Work based on transaction tree Merkle roots and short (here, ten seconds) block times called Proof-of-Wait™. Writcoin defines a coinbase transaction as being any input-less transaction, regardless of origin, and defines a blockbase™ transaction as being any coinbase transaction with only one, unspendable output. (By default, the nonce of a block is the “value” of the sole output of its first transaction, a blockbase transaction.)

Its software patch (and, perhaps, clearnet software patch) was last updated 10 October 2015 (hardfork: 24 August 2015). Its primary seed node is accessible through Tor.


Great Empire Coin™ (GEC) is the official currency of Great Empire of Earth, is divisible into cents and mills, and has denominations of mega-, terra-, and exacoins. Earth has a heterarchical monetary authority: anyone may “mint” coins through an official channel (e.g., Writcoin) and have these coins certified “Great Empire Coin (GEC)” by the Empire.
