Asset split and Blockchain Seeding

Asset Split

Break apart Assets into Unit-Of-Measure and Assets as they represent divergent behavior.

Blockchain seeding

We've included the following unit-of-measure and asset standards in the hashblock genesis creation:

1. units: http://unitsofmeasure.org/trac
2. assets: https://en.wikipedia.org/wiki/ISO_4217

Shared Keys for Private Exchanges

Breaking Changes

Significant changes as we mature #B:

1. Now uses Elliptic Curve Diffe-Hellman shared key instead of Fernet (#81), changing how UTXQ/MTXQ are encrypted. The old encrypted data will not be migrated.

2. In oder to remove the user constraint of managing asset prime number (values) (#87), we've changed the address scheme. Refer to Address Scheme

General:

Core focus is on removing the fernet key as THE encryption/decryption key for exchange data in the PoC and move on to a shared key PoC solution and optimizing Asset unique value representation (prime numbers).

Breaking Change:

We are happy to announce hashblock-exchange (#B) alpha for your pleasure.

Hashblock Exchange enables encrypted data in flight and at rest while also providing matching exchange transaction anonymity on the Hyperledger/Sawtooth system.

Note: Still alpha level, not ready for prime time
