@zhoujianfu paste.city is very nice, almost exactly what we need for a proof of concept! Thanks for pointing out. Will keep you up to date 👌
I have a feeling Memo will extend far beyond one blockchain. Imagine different blocckians as subthreads of the common protocol. One key everywhere, optimally tied to a community identity system (Namecoin).
In each blockchain you can follow different community members.

edit: different blockchains, common identity system

So every memo account has corresponding public key already exposed in the blockchain. You can fetch any transaction and extract public key from it. And than do ECDH with it.
then
You can’t do ECDH from just a public address, cause right, it’s a hash not a public key. But you expose actual public key when you transact.

Good point. I'm not soo cryptography-savvy, so I wasn't sure if just from somebody's public address (isn't it a HASH of the public key?) you could encrypt messages to them? Can you?

then. The problem is, the memo is so addictive, how can I stop using is for a minute? Will do some chi kung breathing.
Ok, I really need to sit down and describe the protocol as a whole with all the tiny details figured out. We can than proceed to PoC implementation, as a browser extension for ex.
As a cheery on top, the url during initiation can point to an onion/i2p service, for extreme anonymity and meta-data free communication.
“...If someone famous is getting more e-mail than they can read, but would still like to have a way for fans to contact them...”
The anti-spam filter is built-in (initial tip threshold) , can be large for famous people, just as Satoshi invisioned.
The difference from today’s email system is that your are not tied to a particular provider. All social connections are on a blockchain level. You key is your account.
And cause we are in a free market, there will be many such web servers (just like email providers), and each will have a community-built rating.
The limit is basically time/storage/bandwidth consumed. Can be very cheap for users, but can be a viable business model is idea catches up.
You use that key to post/update txt files to that server. The server keeps an account for tokens, and discards tokens once the limit is reached.
Such as you tip to a web server memo account as if you were initiating a message with all that ECDH dance, and as a “reply” from web server you receive a token (key).
The web server party can be a anything like a dropbox. But I can envision dedicated web servers run by community members that accept messages on a paid basis
That way, Alice can download Bob’s second file first to check whether there is an updated version of the “messages” file, and only query it if the hash differs from Alice cash
Ok so, there can be one txt file for messages, and another with only the hash of the previous one.
edit: only, once... sorry for the mistakes folks, that’s partially autocorrection and partially cause I am in a hurry.
Important part: two parties you use blockchain to initiate a contact. One they have url’s of each other, the post messages by updating the txt files on a web server.
That way, you can filter all the addressee’s memo action and catch one which has a reply to your message once (and if) it’s posted.
