The Role of Hardware and Trusted Execution Environments in Blockchain Scaling and Security
*Hardware is not just about ASICs for mining. It will impact the next-generation design of blockchain peer nodes, remote utilities, and infrastructure*

The introduction of new ASIC mining hardware for accelerated computation of proof-of-work algorithms has recently jolted the blockchain community into an increased awareness and discussion of hardware. But hardware impacts all aspects of blockchain architecture including peer nodes and network infrastructure. Firmware and microcode increasingly blur the line between hardware and software. Moreover, blockchains provide an opportunity to re-think and extend the traditional notions of Trusted Execution Environments to make them far more useful.

As a community, we pay insufficient attention to the dramatic impact which these items exert on scaling and security.
