From 6decf0b54b3c9a04ca2ae2e65ec8f9aee7b962c8 Mon Sep 17 00:00:00 2001 From: Matt K <1036969+mkrump@users.noreply.github.com> Date: Fri, 5 Jan 2018 11:55:00 -0600 Subject: [PATCH] Remove pubsub and replace w/ polling head of chain (#122) * Rename geth package structs to not be prefaced with package name * No longer need to dump schema since Travis uses migrate * Rearrange history package * Removed double request for receipt from block rewards * Remove Listener + Observers and Replace w/ Polling Head * Potential Short term Issue w/ Infura (ignore these tests for now) --- Gododir/main.go | 4 -
