Buy ARPA

ARPA Chain (ARPA) is a blockchain platform that aims to solve one of the biggest challenges in blockchain technology: securely sharing and processing data without compromising user privacy. Launched in 2018, the platform uses Secure Multi-Party Computation (SMPC), a technology that allows data to be processed without being seen by any of the parties involved.

The main goal of ARPA Chain is to enable users and organizations to securely share and use sensitive information without revealing the underlying data. This is especially useful in industries such as finance, where transactions can be performed without exposing sensitive information such as bank details. ARPA Chain allows confidential data to be processed in calculations while keeping it encrypted.

Another key feature of ARPA Chain is its focus on scalability and efficiency. Many blockchains, such as Ethereum, struggle with delays and high fees when processing many transactions. ARPA offers a solution by performing calculations off-chain via a layer 2 solution. This means that complex calculations are not performed on the main blockchain, but on a second layer, which speeds up transactions and reduces costs. This makes ARPA attractive to both enterprises and developers.

The ARPA token plays a central role in the ecosystem. It is used to pay for various services on the network, including the fees for secure multiparty computation. Users can also stake ARPA tokens as collateral to ensure the reliability and performance of the network. Computational nodes, which provide computing power to the platform, are required to stake ARPA tokens as a guarantee for their services. These tokens can be lost if a node breaks the rules or does not perform a task correctly.

Over the years, ARPA Chain has expanded its network and established major partnerships with companies such as Blockcloud and Mirror World. The platform finds applications in various sectors, including finance, healthcare, and even the emerging metaverse.

Who founded ARPA Chain?

ARPA Chain was established by a team of skilled blockchain and cryptography experts, including Felix Xu, Yemu Xu, Derek Zhang, and Jiang Chen. Felix Xu and Yemu Xu, who are also actively engaged in other blockchain ventures like Bella Protocol, serve as the team’s core members. Their combined expertise in cryptography, blockchain technology, and building successful businesses has enabled them to develop ARPA Chain. The project is led by the core team, but also collaborates with a broad network of partners and developers worldwide to further advance the platform.

ARPA Chain offers various applications that are aimed at both end users and developers. Here are some of the key features:

• Data trading: Users can securely trade or rent sensitive data without compromising the privacy of that data.
• Financial services: Banks and financial institutions can perform secure, privacy-preserving calculations, such as fraud analysis, without accessing users' personal information.
• Targeted advertising: Advertisers can reach customers without violating their privacy, creating a better balance between relevant advertising and privacy protection.
• Metaverse integration: ARPA's Randcast program provides random, verifiable numbers for applications within the metaverse, such as generating NFTs and staging events in games.
• Monetization of personal data: Users can securely monetize their personal data in an environment where that data remains encrypted.

ARPA Chain uses advanced cryptographic techniques, with Secure Multi-Party Computation (SMPC) playing a central role. This technology allows users to share and process confidential data without exposing the data itself. ARPA offers a scalable and secure solution for privacy-sensitive applications, while maintaining efficiency.

Secure Multi-Party Computation (SMPC)

SMPC is the core technology of ARPA Chain and enables data processing without exposing it to the parties involved. Unlike techniques such as homomorphic encryption or zero-knowledge proofs, SMPC offers an optimal balance between scalability, flexibility and efficiency. This makes it an ideal solution for applications that process sensitive information, such as in the financial and healthcare sectors.

SMPC involves distributing a computation across multiple parties, with each party processing only a portion of the data without access to the entire dataset. The results of these computations are then aggregated so that the final outcome is available without revealing the original data.

The ARPA Chain consensus mechanism

ARPA Chain uses a unique consensus mechanism designed to ensure both efficiency and security. This mechanism consists of three key components:

• Proof-of-Correctness: Ensures that only selected nodes are responsible for performing computations, increasing network efficiency and speed.
• Proof-of-Computation: Keeps track of which nodes are performing computations and rewards them based on their contribution to the network.
• Proof-of-Secureness: Validates computations performed off-chain in Trusted Execution Environments (TEEs) to ensure that computations are performed correctly and securely.

Edgecast and verifiable randomness

Another key component of ARPA Chain is the Randcast program, which focuses on generating random, verifiable numbers (RVN) for applications such as NFT creation and metaverse events. Randomness is crucial for security in blockchain networks, and ARPA offers an efficient and cost-effective solution for developers who need random numbers for their applications with Randcast.

The ARPA token is the native cryptocurrency of the ARPA Chain network and plays a vital role in the operation of the platform. ARPA is primarily used as a means of payment for various decentralized services within the network, such as performing secure multiparty computations. In addition, computational nodes are required to stake ARPA tokens as collateral to guarantee their computational power and incentivize honest behavior. This stake can be forfeited if a node does not meet the requirements or misbehaves.

In addition, network participants can stake ARPA tokens, which contributes to the security and efficiency of the network. Stakers receive rewards in the form of additional ARPA tokens depending on their contribution. In addition to its functional use, ARPA also functions as a governance token. This gives token holders voting rights in important decisions regarding the development and management of the network. The total maximum supply of ARPA is limited to 2 billion tokens.

ARPA staking is a way for users to contribute to the security and performance of the network while being rewarded with additional ARPA tokens. To stake ARPA, users can stake their tokens via supported staking platforms or wallets that offer staking services.

When you stake ARPA, your tokens are locked up for a period of time and used to support computing power and validate transactions. Stakers receive rewards based on the number of tokens staked and the duration of the staking process. This encourages users to continue to stake their tokens, increasing the reliability and efficiency of the network.

ARPA Chain stands out for a number of unique features within the crypto and blockchain world:

• Privacy-preserving Secure Multi-Party Computation (SMPC): ARPA uses SMPC technology, which allows sensitive data to be shared and processed without exposing the data itself, providing optimal privacy protection.
• Scalability and efficiency: By using off-chain computation, ARPA avoids overloading the main blockchain, resulting in faster and more affordable transactions.
• Interoperability: ARPA is blockchain agnostic and can interoperate with multiple blockchains, making the platform extremely flexible for diverse applications.
• Randcast technology: ARPA provides verifiable random numbers for applications in the metaverse and NFT creation, making it unique in providing secure random number generation (RNG).
• Tokenomics and governance: The ARPA token plays a clear role in both staking and governance, allowing token holders to have a say in the development of the network and earn rewards for actively participating.
