Whitepaper

Chaingear - The consensus computer driven database framework

Principles of Chaingear

Chaingear is a set of smart contracts which operating in consensus computer with following principles:

Databases creates by user createDatabase call for Chaingear witch mints database-linked NFT token for user and deploys database with support of CRUD+TF operations. Token controls adminship of database.
Admin initializes database with given table/tables data schema.
Database admin may set user permissions for entry creation and fee for adding.
Each entry in database linked to NFT token (primary key) which grants a set of rights for token-entry operation as UPDATE/DELETE and TRANSFER/FUND.
Chaingear for given platform acts as Consensus Computer Driven Database as a Service
Application specific business logic should be available to operate on top of database/databases.

Chaingear on EVM, 0.1 Euler PoC

Chaingear

Chaingear is database of database which allow deploy new databases from there and creates an associated token for adminship.
Chaingear allow deploys different types of databases with defined functionality with connects with databases builders.
Database Builder is a fabric of databases of given type.
Databases may have their unique code base as an extension to the basic database.
Database-token may be transferred, sold/traded alongside with their right adminship.
Chaingear have fees for database creation.
Chaingear have benefitiaries which may claim collected fees proportional to their shares.

Database

A database is a smart contract which defines NFT tokens linked to entries. User creates database with given name and token symbol for entries.
After deploy database admin initializes database with data schema table/tables and this allows them or/and other users to create a systematic collection of data, where rights to operations with entry defined by entry-token ownership.
Entries data lives in Schema contract.
Each entry may be publicly funded, an entry-token owner may claim collected funds.
Database admin may set policy for entry creation: {OnlyAdmin, Whitelist, AllUsers} and fee for the entry-token creation and next claim fees.
Also admin may set multiple database's beneficiaries which may claim collected fees proportional to their shares.
