Anatoly Yakovenko 0135971769 Fast UdpSocket reader
* message needs to fit into 256 bytes
* allocator to keep track of blocks of messages
* udp socket receiver server that fills up the block as fast as possible
* udp socket sender server that sends out the block as fast as possible

Greg Fitzgerald 5dd567deef Rename Genesis to Mint
Genesis is a story of creation. We should only use that term to
for the event log that bootstraps the system.

Greg Fitzgerald 1436bb1ff2 Move entry into its own module
Hmm, Logger doesn't depend on log.

Greg Fitzgerald 1b77e8a69a Move Event into its own crate
The log crate was starting to be the catch-all for all things
related to entries, events, signatures, and hashes. This split
shows us that:

* Event depends only on signatures, not on hashes [directly]
* All event testing was done via log testing (shame on me)
* Accounting depends only on events

Greg Fitzgerald 0443b39264 Allow event log to hold events of any serializable (hashable) type 2018-02-26 16:42:31 -07:00
Greg Fitzgerald 08e501e57b Extend the event log with a Claim event to claim possession
Unlike a Discovery event, a Claim event associates a public key
with a hash. It's intended to to be used to claim ownership of
some hashable data. For example, a graphic designer could claim
copyright by hashing some image they created, signing it with
their private key, and publishing the hash-signature pair via
the historian. If someone else tries to claim it as their own,
the designer can point to the historian's log as cryptographically
secure evidence that the designer's copy existed before anyone
else's.

Note there's nothing here that verifies the first claim is the actual
content owner, only that the first claim almost certainly happened
before a second.

Greg Fitzgerald fa4e232d73 Add serialization/deseriation support to event log
See bincode and serde_json for usage:

Fixes #1

Greg Fitzgerald d97112d7f0 Explain proof-of-history in the readme
Also:
* Hash userdata so that verification works as the readme describes.
* Drop itertools package. Found a way to use std::iter instead.

Fixes #8
2018-02-20 14:04:49 -07:00
Greg Fitzgerald 0297edaf1f Use sha256 hashes instead of Rust's builtin hasher.
Causes a 20x performance degradation. Enabling asm did not
speed things up.

Greg Fitzgerald fd209ef1a9 Rename event crate to log 2018-02-18 09:59:33 -07:00
Greg Fitzgerald 831e2cbdc9 Add historian
A microservice that continuously generates hashes, only stopping to
tag messages with the latest hash.

Greg Fitzgerald a74540470a Rename Tick to Event
* Define a tick to be an event with no user data.
* Use the term "event log" for now.
** Reserve the word "entry" for hash entries, and "item" for array items.
** Reserve the word "blockchain" for when the event is a block of something.
** Reserve the word "ledger" for when the event is of a particular type,
   such as transactions.
