I am tired of spam. Can we create a protocol where in the header there is a X-Human-Blob and X-Human-HashIf the Sha256 of the email content together with the blob start with Y zeros, then the receiving email client knows the creator of such email INVESTED energy to create the email. Each receiving email client can demand different number of zeros as compute becomes cheaper.That way, when I send a cold email to someone in which the X-Human-Hash starts with a 1000 zeros is IT CLEAR THAT IT IS A F-ING IMPORTANT EMAIL!! NOT SPAM. This would important for legal teams, engineering teams, etc.It is the 21st century, I have a SaaS that makes $1.5m per year, I live in a super advanced nation, use best practices, and I CAN'T GUARANTEE an important email INBOXES!? How did we get here.Thoughts?If you wanna work on this with me email me at somid3-at-gm@il-D0t-c0m
