Introduction

OAK, or Onchain Automation Framework, is equipped with a novel smart contract virtual machine that supports an event-driven execution model, enabling developers to build fully autonomous decentralized application. By extending the current set of atomic operations, namely, opcodes of EVM, OAK introduces an innovative way for contracts to interact with each other. Contracts can emit signal events, on which other contracts can listen. Once an event is triggered, corresponding handler functions are automatically executed as a new type of transaction, signal transaction. Applications implemented with the new approach will eliminate the dependency of unreliable mechanisms like off-chain relay servers, and in return, to significantly simplify the execution flow of the application and can avoid security risks such as relay manipulation attacks.

Based on the above, OAK has some features.

• OAK Virtual Machine
• Autonomous Transactions
• On-chain Relayer
• Validator Staking

Live Networks

• oak-testnet: standalone testnet (built off of substrate)
• neumann: testnet parachain (coming soon)
• turing: kusama parachain (coming soon)
• oak: polkadot parachain (coming soon)

Install OAK Blockchain

• OAK releases releases.
• Node custom types.

Latest version you can try to build from source.

Building from source

Ensure you have Rust and the support software (see shell.nix for the latest functional toolchain):

curl https://sh.rustup.rs -sSf | sh
# on Windows download and run rustup-init.exe
# from https://rustup.rs instead

rustup update nightly
rustup target add wasm32-unknown-unknown --toolchain nightly

You will also need to install the following dependencies:

• Linux: sudo apt install cmake git clang libclang-dev build-essential
• Mac: brew install cmake git llvm
• Windows: Download and install the Pre Build Windows binaries of LLVM from http://releases.llvm.org/download.html

Install additional build tools:

cargo +nightly install --git https://github.com/alexcrichton/wasm-gc

Install the OAK node from git source:

git clone [email protected]:OAK-Foundation/OAK-blockchain.git    

Build your executable:

cargo build --release

Run your Local Network

Local Setup

Launch a local setup including a Relay Chain and a Parachain. Note: local PARA_ID is defaulted to 2000

Launch the Relay Chain

# Compile Polkadot with the real overseer feature
git clone https://github.com/paritytech/polkadot
cargo build --release

# Alice
./target/release/polkadot \
--alice \
--validator \
--tmp \
--chain ../OAK-blockchain/resources/rococo-local.json \
--port 30333 \
--ws-port 9944

# Bob (In a separate terminal)
./target/release/polkadot \
--bob \
--validator \
--tmp \
--chain ../OAK-blockchain/resources/rococo-local.json \
--port 30334 \
--ws-port 9945

Reserve the Parachain slot

1. Navigate to Local relay parachain screen
2. Click + ParaId
3. Reserve paraid with the following paramaters
   • reserve from: Alice
   • parachain id: 2000
   • reserved deposit:

Prep the Parachain

# Compile
git clone https://github.com/OAK-Foundation/OAK-blockchain
cargo +nightly build --release

# Export genesis state
./target/release/neumann-collator export-genesis-state > genesis-state

# Export genesis wasm
./target/release/neumann-collator export-genesis-wasm > genesis-wasm

# Collator1
./target/release/neumann-collator \
--alice \
--collator \
--force-authoring \
--tmp \
--port 40333 \
--ws-port 9946 \
-- \
--execution wasm \
--chain resources/rococo-local.json \
--port 30335 \
--ws-port 9977

Register the parachain

1. Navigate to Local relay sudo extrinsic
2. Register your local parachain with the local relay chain (see the image below for the extrinsic). Note** the files mentioned are the ones you generated above.

Test the parachain

1. Navigate to Local parachain
2. WAIT.... It takes a while for the registration process to finish.

Future Work

Here are the key milestones.

1. Start the crowdloan with Kusama network
2. Become a Kusama Parachain (TBA)
3. Become a Polkadot Parachain. (TBA)
