The Initial Coin Offering (ICO) price of the ARPA token was $0.02 in the first round and $0.018 USDT per ARPA during its IEO (Initial Exchange Offering) on Biss.com. The initial allocation of the ARPA token was structured as follows:

• Bootstrap Rewards: 30%

• The Team: 20%

• Foundation: 15%

• Reserve: 13%

• Private Sale: 10%

• Public Sale: 7%

• Ecosystem: 5%

This allocation strategy was designed to support the project’s vision and incentivize various stakeholders within the ARPA ecosystem.

• Market Volatility:

• Cryptocurrency prices are highly volatile.

• Regulatory Risks:

• Potential for regulatory changes impacting the network.

• Technical Risks:

• Risks associated with the complex cryptographic techniques used.

• Adoption Risks:

• The network’s success depends on widespread adoption.

• Competition:

• The token faces competition from other privacy-preserving and scalability solutions.

The ARPA Chain whitepaper outlines a secure computation solution for blockchain networks, focusing on privacy-preserving technologies and scalability. ARPA Chain employs Secure Multi-Party Computation (SMPC), allowing multiple parties to compute a function over their inputs while keeping those inputs private.

The ARPA protocol is divided into two phases: preprocessing and computation. The preprocessing phase is independent of the function and data, providing the raw materials for computation. During the computation phase, private inputs are secretly shared among parties, who then collaboratively perform operations according to an arithmetic circuit. The results are only revealed after computation verification.

ARPA tokens serve five critical functions within the ecosystem:

• Medium of Exchange:

• ARPA tokens are used for all transactions within the ARPA computation network.

• Computing Cost:

• Tokens are exchanged to perform secure multiparty computation, compensating computation providers.

• Stake:

• Computation providers use ARPA tokens as a safety deposit, with penalties for aborting computation or other malicious actions.

• Transaction Fee:

• Similar to Ethereum’s gas fee, ARPA tokens are paid to nodes facilitating transactions.

• Backing of Data or Model:

• The network allows backing of public data or models, incentivizing early adopters and backers of ARPA’s data marketplace.

Experiments conducted in privacy-sensitive applications, such as auctions or machine learning, demonstrate that with suitable optimization, the overhead caused by computation and communication can be largely mitigated. ARPA Chain supports various applications, including fintech, healthcare, and AI, by enabling “Private Smart Contracts” that protect data privacy, function privacy, and participants’ identities.

ARPA Chain is designed to be blockchain-agnostic, adaptable to multiple blockchains, and prioritizes decentralization and community governance. The network’s threshold signature service is decentralized, tamper-proof, and cryptographically secure, with signatures verified on-chain.

ARPA Chain represents a significant step forward in privacy-preserving computation on blockchain networks. Its use of SMPC and a dual-phase protocol for secure computation, combined with a well-thought-out token economy, positions ARPA as a promising solution for a wide range of applications that require both privacy and scalability.
