Thanks Megaspaz!) Like the left turn this is another hand signal that you should know if you have your license. Unlike the left hand turn this one is a little more tricky to figure out if you aren't familiar with it so don't expect your average car driver to know what this means.
A Single Photon Emission Computed Tomography (SPECT) scan is a type of nuclear imaging test that shows how blood flows to tissues and organs. A SPECT scan integrates two technologies to view your body: computed tomography (CT) and a radioactive material (tracer). The tracer is what allows doctors to see how blood flows to tissues and organs.
What is Quantstamp? Quantstamp is the first smart contract security-auditing protocol. What does this mean? Quantstamp will check for errors and vulnerabilities in smart contracts to preserve their security. Why is this important? In June 2016, a hacker stole $55M Ethereum coins from the DAO due to a bug in its smart contract1. In July 2017, another hacker took over $30M in Ether from crypto companies due to a one-word bug in the smart contract code in the Parity multi-sig wallet (from the whitepaper). How will Quantstamp do this? They will do this in two ways: 1. Quantstamp will use an automated and upgradeable software that will check for errors and vulnerabilities in smart contracts. 2. An automated bounty payout system that will reward human participants for finding errors in smart contracts. But why is an automated system needed?
