Reworking Bitcoin Transaction Fees

Transaction fees as they are currently implemented in the original Bitcoin code suffer from a few problems:

The rules are complicated and ad-hoc
Fees are hard-coded and do not reflect real costs
Adding fees to a transaction doesn't necessarily make it more likely the transaction will be confirmed more quickly.

I'm proposing changing the rules miners use to decide what transactions to include in their blocks, and changing the way clients tell users whether or not any particular transaction "needs" a fee to be confirmed in a reasonable amount of time.

WAL-E needs to be installed on all machines, masters and slaves.

How to install WAL-E

Only one machine, the master, writes WAL segments via continuous archiving. The configuration for the master postgresql.conf is:

archive_mode = on
archive_command = 'envdir /etc/wal-e.d/env wal-e wal-push %p'
archive_timeout = 60

	// directly uploads to S3

	// See http://philfreo.com/blog/how-to-allow-direct-file-uploads-from-javascript-to-amazon-s3-signed-by-python/
	// See https://github.com/elasticsales/s3upload-coffee-javascript

	editors.Filepicker = editors.Text.extend({
	tagName: 'div',

	events: {
	'change input[type=file]': 'uploadFile',

	# Demonstrates three important caveats as of now:
	#
	# 1. You you have to use `touch: true` in the `belongs_to` declaration,
	# to automatically notify the parent model about the update.
	#

	# Run with: rake environment elasticsearch:reindex

	namespace :elasticsearch do
	desc "re-index elasticsearch"
	task :reindex => :environment do

	klass = Place
	ENV['CLASS'] = klass.name
	ENV['INDEX'] = new_index = klass.tire.index.name << '_' << Time.now.strftime('%Y%m%d%H%M%S')
