ua-js

Repo to calculate UserAuthority (UA) via follower data within Steem.

Implementation plan

1. read all follower transactions, chronologically, from the blockchain

• for a Proof of Concept (PoC), we will however begin with retrieving data from steemdata.com (MongoDB)

2. store follower transactions in a temp MongoDB collection: followDB

• update followDB per blockchain block
• include last block id

3. approximate all user UA via multi-iterational substitution, begin with 1 per account, store in temp MongoDB collection: uaDB

• equilibrium state is reached when abs[(it(n) - it(n-1)] < x % (confidence interval to be decided, can be very high)

4. store, as binary, the equilibrium per user as [uid: ua] : ua.db (binary file)
5. hash-encrypt ua.db , store hash in latest blockchain block for consensus
6. witnesses read ua.db per user (let's say 8 bytes per user: UA(user 100,000) is found at byte 800,000
