A Transaction Fee Market Exists Without a Block Size Limit
This paper shows how a rational Bitcoin miner should select transactions from his node’s mempool, when creating a new block, in order to maximize his profit in the absence of a block size limit. ToExpand

A novel method for assessing the 3-D orientation accuracy of inertial/magnetic sensors.
A novel method for assessing the accuracy of inertial/magnetic sensors is presented. The method, referred to as the "residual matrix" method, is advantageous because it decouples the sensor's errorExpand

Selfish Mining Re-Examined
TLDR
We present a novel, modified selfish mining strategy, called intermittent selfish mining, that, perplexingly, is more profitable than honest mining even when the attacker performs no selfish mining after a difficulty adjustment. Expand
