Deno's sandbox security is somewhat similar to Mandatory Access Control (MAC) implemented by SELinux and AppArmor. But it looks like not as fine-grained as MAC. In the example: deno run --allow-net myWebserver.ts With SELinux, one can

In case there are multiple conflicting transactions (for double-spending purpose), the network will only accept the first one and reject the rest. So the micropayment processor needs to wait for a few seconds when it receives the first tran

Since it is a micropayment, it is possible (or acceptable) to accept payment with zero confirmation (in less than 10 seconds), as pointed out by Satoshi in the "Bitcoin snack machine" post: https://bitcointalk.org/
