Blockchain for the IRS

Bitcoin and blockchain may have jumped the shark over the past few years. But blockchain, which is simply a chain of cryptographic hashes, seems like it would be an ideal mechanism for the IRS to track payments and taxes. 

USPS Informed Delivery

I just signed up for the US Post Office's Informed Delivery which e-mails you a scan of that day's inbound mail. It's very handy and works as advertised.

The USPS started this service as a pilot in 2014 and a few years later they rolled it out to most of the country with more than 15 million. Give it a try – it's free, a bargain at twice the price.
