Ika Network represents a paradigm shift in blockchain interoperability. As the first sub-second Multi-Party Computation (MPC) network built on the Sui blockchain (formerly known as dWallet Network), Ika aims to enable zero-trust interoperability across different blockchains. It supports up to 10,000 transactions per second (TPS) and scales to hundreds of signing nodes. The project addresses one of the most pressing challenges in the decentralized finance ecosystem: achieving secure and efficient cross-chain asset coordination without relying on traditional bridge mechanisms.
As a parallel MPC network offering sub-second latency, high-throughput scalability, and support for hundreds of nodes, Ika is centered on zero-trust security. It is dedicated to redefining digital asset security and the multi-chain DeFi landscape. Its native token, IKA, powers network operations, governance, and economic incentives—laying a comprehensive foundation for the next generation of decentralized applications.
The blockchain ecosystem has become a fragmented set of siloed networks. While each chain offers unique functionalities, cross-chain interaction remains limited. Traditional bridges have suffered repeated security breaches, resulting in billions of dollars in losses and eroding trust in cross-chain operations. Ika addresses these limitations through a novel multiparty computation approach.
With Zero-Trust Protocols (ZTP) and dWallet technology, Ika enables programmable native assets (e.g., Bitcoin, Ethereum, Solana) on the Sui blockchain. This eliminates reliance on centralized bridges and introduces a secure, decentralized way to manage cross-chain assets.
Developers can now build applications that natively interact with multiple chains while preserving the unique security properties of each. With Ika's integration on Sui, decentralized applications can now support multichain assets natively.
Sub-Second Latency: Executes MPC operations at near-instant speeds, rivaling centralized systems while maintaining decentralization.
Massive Scalability: Supports up to 10,000 TPS, ideal for high-frequency trading, gaming, and other performance-sensitive use cases.
Zero-Trust Security: Advanced cryptographic protocols ensure that no single node can compromise the network, enabling true trustlessness.
Native Multichain Support: Unlike bridge-based models, Ika offers native support for major chains like Bitcoin, Ethereum, and Solana within the Sui ecosystem.
Ika's core innovation lies in its implementation of the 2PC-MPC (Two-Party Computation – Multi-Party Computation) cryptographic framework. This advanced approach enables multiple parties to collaboratively perform cryptographic operations without revealing their individual input data, laying the foundation for secure distributed key management.
The network operates through a threshold signature system, requiring multiple nodes to jointly authorize transactions. This distributed architecture eliminates single points of failure while maintaining operational efficiency through parallel processing capabilities.
dWallet (Decentralized Wallet) technology represents a fundamental breakthrough in cross-chain asset management. Unlike traditional multisig wallets that require pre-configured signers, dWallet leverages threshold cryptography to create dynamically managed wallets controlled by a distributed network of validators. It supports the following features:
Dynamic Key Generation: Keys are jointly generated by network participants, ensuring no single entity has full control.
Threshold Signature Scheme: Transactions require collaboration from a threshold number of validators, achieving security through decentralization.
Cross-Chain Programmability: dWallets can interact with multiple blockchain networks simultaneously, enabling truly cross-chain smart contracts.
Ika is a high-performance MPC interoperability network built on a fork of the Sui blockchain, scheduled to launch in Q1 2025. Serving as the interoperability layer for Sui, Ika aims to enhance cross-chain interactions and build a more connected DeFi ecosystem. Choosing Sui as the underlying blockchain offers several strategic advantages:
High Performance: Sui's parallel execution model aligns perfectly with Ika’s high-throughput MPC requirements.
Move Programming Language: Move's asset-centric programming paradigm provides native support for cross-chain asset management.
Object-Centric Architecture: Sui's unique data modeling enables a more efficient representation of cross-chain assets and operations.
Ika leverages several cutting-edge cryptographic technologies to achieve its performance and security goals:
Elliptic Curve Diversity: The choice of elliptic curves for different cryptographic algorithms (e.g., ECDSA, EdDSA, Schnorr) affects the computational cost of Distributed Key Generation (DKG) for creating dWallets and the cost of threshold signature generation.
Distributed Key Generation (DKG): An advanced protocol that enables the generation of cryptographic keys across a distributed network without a single point of control.
Threshold Homomorphic Encryption: Enables multiple parties to perform computations on encrypted data, supporting complex cross-chain operations while preserving privacy.
Pre-signature Optimization: The pre-signing phase allows the network to prepare cryptographic materials in advance, reducing latency and significantly improving transaction processing speed.
The IKA token has an initial total supply of 10 billion. As a community-driven protocol, over 50% of the tokens are allocated to the community. Among these, 6% (600 million tokens) will be distributed through the first Ika community airdrop at mainnet launch.
The IKA token serves as the economic backbone of the Ika Network, supporting several core functions:
Network Operation: IKA is used to pay for network operation fees, secure the network through staking, and enable decentralized governance.
Computation Cost Management: IKA also underpins Ika's fine-tuned economic system for cryptographic operations. Different cryptographic functions incur varying computational costs, which in turn affect how users are charged when interacting with the network.
Ika leverages its native IKA token to enable decentralized governance and economic incentives, building a permissionless Proof-of-Stake (PoS) MPC network on Sui that supports secure, censorship-resistant threshold signatures.
The network adopts a sophisticated PoS mechanism to achieve multiple objectives:
Validator Selection: IKA staking determines which nodes are eligible to join the MPC committee responsible for threshold signing.
Security Incentives: Stakers are economically rewarded for maintaining the network’s security and availability.
Decentralization: The permissionless nature of staking ensures the network remains decentralized and resistant to centralization risks.
Ika employs a market-driven dynamic pricing mechanism centered around the IKA token, designed to balance ecosystem incentives, ensuring MPC nodes receive adequate rewards for their computational contributions and reliability, while providing users with competitive and predictable pricing.
This innovative model establishes a self-regulating economic system that:
Adapts to changes in network demand.
Accounts for differences in computational complexity among various cryptographic operations.
Maintains the economic sustainability of network participants.
Provides predictable pricing for end users.
Changing the MPC node committee requires intensive cryptographic computations to securely redistribute shares of the network's threshold homomorphic decryption keys among new participants. The economic model addresses these complex operations by:
Distributing restructuring costs among network users.
Incentivizing long-term stability of the committee.
Ensuring sufficient compensation for computational resources.
