## What is the ARPA?
The ARPA BLS Threshold Signature Scheme (BLS-TSS) Network stands as a groundbreaking decentralized cryptographic system dedicated to executing BLS threshold signature tasks. Its inaugural product, Randcast, harnesses the ARPA Network's capabilities to provide secure and dependable random number generation on the Ethereum blockchain. The utilization of threshold cryptography, particularly the Boneh–Lynn–Shacham (BLS) threshold signature scheme, marks a pioneering shift towards distributed and tamper-resistant random number generation, elevating security and trust in cryptographic applications.

## Core Architecture and Standards
The ARPA BLS-TSS Network adheres to a set of core standards that delineate its architecture and interactions, laying a robust foundation for its operations. The Distributed Key Generation (DKG) process, a pivotal phase in the network, involves various nodes generating group public keys and individual partial keys. These cryptographic elements form the basis for producing random numbers in a distributed manner, preventing any single entity from exerting undue control.

### Smart Contracts Orchestrating the Network
- Controller Contract: Central authority for DKG process coordination, node registration, and group management.
- Coordinator Contract: Facilitates interaction between participants and the network during the DKG process, managing phase transitions.
- Adapter Contract: Links Randcast protocol to threshold signature-based random number generation, ensuring secure and reliable randomness results.
- RandcastSDK Library: Provides utilities for interacting with the ARPA network, aiding in processing random numbers and performing operations requiring randomness.

### Key Concepts
- Node: Fundamental entity forming the ARPA Network, responsible for registration, grouping, BLS signature signing, and aggregation.
- Group: Set of nodes grouped together to generate BLS signatures, reconfiguring when a member joins or leaves.
- DKG Process: Initiates group formation, coordinated by the Controller and Coordinator contracts, with nodes committing results after up to four phases.
- BLS Process: Involves generating a BLS signature initiated by the Adapter contract's task assignment, with nodes aggregating and committing the signature.

## Node Rewards and Staking
Staking a minimum of 500,000 ARPA tokens allows nodes to join the ARPA Network and earn various rewards, including user fees, randomness submission rewards, BLS-TSS task rewards, DKG post-process rewards, and community staking delegation rewards. An invite-only early-access period precedes the fully permissionless system, enabling issue identification and resolution for enhanced security and stability.

Staking ARPA tokens becomes an active contribution to fortifying the ARPA network's decentralization and robustness. Participants earn rewards while actively shaping the network's future and promoting a decentralized and reliable system. Staking matters for driving node operation, fortifying security, advancing decentralization, fueling rewards, and catalyzing community engagement.

## Running a Node
Operating a [node](https://coinrotator.app/category/Nodes) involves a deeper engagement in network operations, contributing significantly to security and reliability. A minimum staking requirement of 500,000 ARPA ensures participation, with nodes receiving 5% of the community's total staking reward due to auto-delegation in staking v0.1.

To regulate node behavior, slashing and chilling mechanisms are implemented. Slashing imposes penalties on malicious behavior during the DKG process, while chilling introduces a cool-off period of 7200 blocks for nodes exiting the network, ensuring operational stability.

## Randcast
Randcast, an on-chain verifiable random number generation service, leverages the ARPA Network for BLS threshold signature tasks. The full flow involves the Randcast Adapter Contract, ARPA Network acknowledgment, and Randcast Adapter Contract converting the random seed for the subsequent DApp or Web3 game logic.

In various industries, Randcast serves as a versatile solution for ensuring fair and secure randomness. In gaming, it enhances the dynamic experience by guaranteeing fairness in character attributes, item allocation, matchmaking, map generation, and event outcomes. Blockchain-based lotteries benefit from its transparency, ensuring auditable winner selection. NFTs can utilize Randcast to randomly assign rarity tiers, enhancing tamper-proof randomness. 

The consensus layer of blockchains can embed Randcast as a modular random beacon. Marketing campaigns leverage Randcast to randomly select giveaway winners based on custom metrics. DAO governance benefits from certified fair random sample voting. Generative art gains unpredictability using Randcast, and in scientific research, it aids in reducing bias by randomly selecting representative samples. Finally, in cryptography, Randcast provides cryptographically secure randomness for tasks such as private key generation and random seed generation for encryption.

## Investors
ARPA is proudly backed by Coinbase, Binance Labs, GBIC, and Arrington Capital.

## Project Development
In Jan 2024, the ARPA Network is excited to announce the launch of the Community Pool Staking Program Round II, following the success of Round I and the MainNet launch. Round I saw significant monthly staking, averaging over 50 million ARPA from 120 unique wallet addresses. This support enhanced network security, leading to the successful launch of ARPA Randcast on Ethereum, [Optimism](https://coinrotator.app/coin/optimism), and [Base](https://coinrotator.app/category/Base-Ecosystem). 

Early supporters enjoyed annual reward rates ranging from 18% to over 40%. Round II allocates 1.5 million ARPA tokens monthly as rewards, maintaining a 100 million token cap for the pool. Stakers contribute to network robustness and enjoy flexible depositing and claiming, with a 14-day unlock period for unstaking. The ARPA Network is committed to a multi-chain strategy and expanding the Randcast ecosystem, focusing on Autonomous Worlds, fully on-chain games (FOCG), NFT distribution, wallet management, and DAO governance.
