Part 0, where we introduce our work

This May, together with Nuno Lopes and Juneyoung Lee we made a proposal to add a new

alecco

-- Note: example given is for SQLite but can be adapted to other SQL

-- This is a fast query to sample random rows
-- It gets a list of existing row identifiers (rowids),
-- materializes, sorts, and picks 10.
SELECT * FROM test
    WHERE rowid IN
        (SELECT rowid FROM test
            ORDER BY random() LIMIT 10);

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.
