revision of protocol to be more concise and simple

more work to increase the use of RESTful path queries in general is required simplicity of event format is definitely better now without unnecessary newlines (that are fine, but not great for reading) and the elimination of a bracket-like syntax for tags (they are just a list terminated by the content)
ackchually generates events

+The signature is upon the Blake 2b message hash of everything up to and including the newline preceding it, and only relates to the HTTP POST payload, not including the header.

 Even subscription messages should be signed the same way, to avoid needing a secondary protocol. "open" relays that have no access control (which is retarded, but just to be complete) must still require this authentication message, but simply the client can use one-shot keys to sign with, as it also serves as a HMAC to validate the consistency of the request data, since it is based on the hash.

+IMPORTANT: One shot keys for requests and publications is recommended especially for the case of users of Tor accessing relays, as this ensures traffic that emerges from the same exit or comes to the same hidden service looks the same. However, it should be also pointed out that a client is likely to query for one specific pubkey on a fairly regular basis which should be considered with respect to triggering the use of a new path in the tor connection (or other anonymizing protocol).

 === Use in Data Storage

-The encoding is already suitable for encoding to a database, it is optional to use a somewhat more compact binary encoding, especially if the database has good compression like ZST, which will flatten tables of these values quite effectively.
+The encoding is already suitable for encoding to a database, it is optional to use a somewhat more compact binary encoding, especially if the database has good compression like ZST, which will flatten tables of these values quite effectively, with little overhead cost for lowered complexity.

 === Tags

-Event ID hashes will be encoded in URL-base64 where used in tags or mentioned in content with the prefix `e:`.
-Public keys must be prefixed with `p:` Tag keys should be intelligible words and a specification for their structure should be defined by users of them and shared with other REALY devs.
+Tags are simply a list of `<key>:<field>[;<field>]...\n` and the terminator is the sentinel `\ncontent:<length>\n`

-NOTE: Indexing tag keys should be done with a truncated Blake2b hash cut at 8 bytes in the event store, keys should be short and thus the chances of collisions are practically zero.
-Blake2b is required so it is a good choice to use.
+Common tags would include `event` and `pubkey` and `hashtag` - these are guidelines, the specifics of tag content and syntax is tied to the type, the first string at the top of the event, as described above.

 `subscribe` means to request to be sent events that match a filter, from the moment the request is received. Mixing queries and subscriptions is a bad idea because it makes it difficult to specify the expected behaviour from a relay, or client. Thus, a subset of the `filter` is used.
