Atomically Trading with Roger: Gambling on the success of a hardfork
Patrick McCorry and Ethan Heilman and Andrew Miller
Abstract: We present atomic trade protocols for Bitcoin and Ethereum
that can bind two parties to swap coins in the event that two blockchains
emerge from a single “pre-fork” blockchain. This work is motivated by
a bet between two members of the Bitcoin community, Loaded and
Roger Ver, to trade 60,000 bitcoins in the event that Bitcoin Unlimited’s
planned hardfork occurs and the blockchain splits into two distinct
forks. Additionally we study several ways to provide replay protection
in the event of hardfork alongside a novel mechanism called migration
inputs. We provide a detailed survey and history of previous softforks
and hardforks in Ethereum and Bitcoin.
