3.1.2 Performance and Security Protection
Breaking the "Anonymity = Low Performance" Curse, Taking into Account the Present and the Future
Anonymous technologies often come at the cost of sacrificing performance (for example, Monero has a TPS of less than 10 due to ring signatures, and Zcash has a long verification time due to zk-SNARKs), and lack defense capabilities against future threats such as quantum computing. Through three major technologies of "state sharding + quantum-resistant algorithms + anonymous cross-chain", Imperium Chain realizes the triangular balance of "anonymity, performance, and security".
State Sharding: Realizing 1,000,000+ TPS to Support Large-Scale Commercial ApplicationsTo solve the problem of "limited processing capacity of a single chain", Imperium Chain adopts "state sharding" technology, splitting the blockchain network into multiple parallel "sub-chains (shards)". Each shard processes transactions independently, and data collaboration is realized through the "cross-shard communication protocol":
Sharding division logic: Sharding is based on "transaction type + user anonymous identity hash" - transactions of the same type (such as DEX transactions, asset cross-chain, and AI service calls) are assigned to the corresponding shards. At the same time, through the hash value of the user's anonymous identity, it is ensured that consecutive transactions of the same user are preferentially entered into the same shard, reducing cross-shard communication overhead.
Cross-shard collaboration mechanism: When it is necessary to process "cross-shard transactions" (such as a user holding privacyBTC in shard A and transferring it to a user in shard B), the collaboration is realized through the "shard verification committee mutual recognition" mechanism: the verification committee of the initiating shard generates a "transaction legality proof" and transmits it to the verification committee of the receiving shard through an encrypted channel. The two parties can complete the transaction confirmation without synchronizing the complete data, and the cross-shard transaction delay is controlled within 3 seconds.
Dynamic sharding expansion: When the TPS of a certain shard approaches the threshold (such as 1000 TPS), the system automatically splits it into two new shards and adjusts the load distribution between shards at the same time; when the network transaction volume decreases, idle shards are merged to avoid resource waste. Through dynamic adjustment, the TPS of the entire network can increase linearly with the number of nodes, with a target peak of over 1,000,000+ and a delay of less than 2 seconds, meeting the needs of high-frequency scenarios such as e-commerce payments and cross-border settlements.
Quantum Resistance: Adopting NIST-Certified Algorithms to Resist Future Technological ThreatsWith the development of quantum computing technology, traditional encryption algorithms such as RSA and ECDSA will face the risk of being cracked (for example, quantum computers can crack the ECDSA private key of Bitcoin in a few minutes). Imperium Chain has made early arrangements and adopted the CRYSTALS-Kyber and CRYSTALS-Dilithium algorithms recommended by the National Institute of Standards and Technology (NIST) Post-Quantum Cryptography Standardization Project to build a "quantum-resistant security system":
CRYSTALS-Kyber (quantum-resistant key encapsulation): Used for encrypted communication between nodes and encrypted storage of user private keys. This algorithm is based on "lattice-based cryptography" and realizes encryption by generating "short vectors in high-dimensional lattices". Even if quantum computers have strong computing power, it is difficult to crack the key within a reasonable time, ensuring the security of transaction information during transmission and storage.
CRYSTALS-Dilithium (quantum-resistant digital signature): Used in core scenarios such as transaction signing, node identity verification, and block generation. Compared with traditional ECDSA signatures, Dilithium signatures have a shorter signature length (about 2KB) and faster verification speed (30% faster than other quantum-resistant algorithms) at the same security level, and can be seamlessly compatible with existing blockchain architectures without affecting network performance.
Through the collaboration of the two algorithms, Imperium Chain can not only resist current classical computer attacks, but also cope with the threats brought by quantum computing technology in the next 10-20 years, providing users with a "long-term security commitment" for their assets and privacy.
Anonymous Cross-Chain: ACCL Layer Realizes "Cross-Chain Without Trace", Connecting Multi-Chain Privacy EcosystemsCurrent cross-chain solutions (such as ordinary IBC and Bridge) generally have the problem of "non-anonymous cross-chain process". When users transfer assets from the original chain to the target chain, information such as the original chain address, transfer amount, and cross-chain path will be publicly recorded, leading to privacy leakage when cross-chaining between "anonymous chains and transparent chains". Based on the IBC and Chainlink CCIP protocols, Imperium Chain builds an "Anonymous Cross-Chain Communication Layer (ACCL)" to realize full-process privacy protection:
Asset privacy mapping: When users transfer external assets such as BTC and ETH into the Anonymous Imperium ecosystem, the ACCL layer first verifies the authenticity and ownership of the original chain assets through "Zero-Knowledge Proof", and then generates corresponding "privacy version assets" (such as privacy-BTC and privacy-ETH). During the mapping process, the original chain address and the privacy address are bound through a "one-time hash function", and the outside world cannot associate them; the transfer amount is hidden through zk-SNARKs, and only the verification information of "asset total conservation" is retained.
Anonymous routing of cross-chain transactions: The ACCL layer has a built-in "cross-chain relay node pool". Nodes propagate cross-chain transactions through the Dandelion++ protocol to confuse the source and propagation path of the transactions. At the same time, the verification information of cross-chain transactions (such as asset mapping proof and receiving address legality) is submitted to the target chain through Zero-Knowledge Proof, without exposing the details of the original transaction.
Interoperability of multi-chain privacy assets: The ACCL layer supports cross-chain interoperability with other privacy public chains (such as Monero and Zcash). Through the "privacy protocol adaptation module", asset conversion under different anonymous technology systems is realized. For example, users can map ZEC of Zcash to "privacy-ZEC" through the ACCL layer, and freely trade with privacy-BTC and privacy-ETH on Imperium Chain, while maintaining anonymity throughout the process.
Through the ACCL layer, Imperium Chain not only connects the external chain with the Anonymous Imperium ecosystem, but also builds a "multi-chain privacy asset interoperability network", allowing users to transfer assets between different blockchains without compromising between "anonymity" and "cross-chain convenience".
