Application Logic

Here’s what Application Logic accomplished during the last week:

  • Bootstrapper component for initial launch of the system. This component is in charge of uploading initial types and data into Ledger.
  • http/json API for addressing the system. This API allows creating members, viewing balance, data on a precise member or all existing members.
  • RootDomain smart contract, acting as interlayer when calling API. Also, RootDomain is the parent contract of all other contracts.
  • Compilation and creation of plugins for all smart contracts that exist right now: Wallet, Member, Allowance, RootDomain.
  • Integrational tests for all contracts are ready. The tests check smart contracts’ launch and work within real system components.

Network

For Network, we have accomplished the following:

  • Cascade — a staged data transfer algorithm — for transferring messages between nodes.
  • First iterations for receiving Pulse from Pulsar.
  • DHT refactored — high dependency between network components removed, with test coverage increased.
  • Work on plans to introduce PulseManager — an entity that allows receiving current Pulse and setting a new Pulse.
  • System configuration documented.
  • An adapter for logging with tagging that includes additional metadata (package name, functions, file, line number).
  • Subsystem for collecting metrics.
  • Jet Coordinator (shard chain controller) interface defined, with iteration that uses configuration file.
  • Integration between Message Router and Jet Coordinator.
  • Transformation from Reference(NodeID) to DHT object being addressed.

Ledger

  • PulseManager implemented. This component stores current time slot of a Pulse and entropy data for current and all future and past Pulses. The entropy is used for all pseudorandom calculations on the platform.
  • First iteration of Jet Coordinator. This component allows detecting the exact network node, within which a smart contract must be fulfilled or its results must be stored.
  • Integration with LogicRunner (Smart Contracts). We have run relevant tests for basic cases to make them work correctly.

Smart Contracts

We have simultaneously launched test contracts — Member, Wallet, Allowance, Domain — on the ledger. As a result, now we can work with Delegates and child contracts.

  • Delegate contract fully belongs to the parent contract. Delegate is created by a third party and executes functions of the third party in the parent contract.
  • Parent-child connection is a relationship between the contracts. This way a child contracts always knows his parent contract and parent contract monitors all his children.

A lot of work was done in the Preprocessor (now renamed into Compiler) to make the contracts function fully. Check a short video, showing how different smart contracts can exchange funds on our platform.
