The Bitcoin Epoch Series is an extremely low-time preference open-ended series of artistic works created by Dustin D. Trammell. Each work depicts a BTC/USD logarithmic price chart for each Bitcoin block reward halving period, or, “epoch”, overlaid on top of all the previous epochs that have come before it. Because a Bitcoin block reward halving only happens every four years, a new piece in the series is only created every four years. Each piece is unique and there will only ever be one produced for each epoch. Dustin intends to continue creating one piece per completed epoch until either the U.S. Dollar dies, or he does, whichever happens first. In each piece, the epoch represented in the name of the piece is depicted in white on a black background. Each epoch that has come before it is laid on top of it in reverse order such that the first epoch is always the foremost layer. Each epoch other than the most recent is colored and etched according to the preferences of the owner of the previous piece in the series. When a new Bitcoin halving occurs, the current owner of the most recent piece in the series may collaborate with Dustin to choose the color and etching for the epoch represented by the piece that they own in the next piece being created, allowing the owners of the art to influence the design of all future pieces in the series.
