3.1.1 Triple Anonymous Protection
A Full-Link Privacy Barrier from "Transaction Verification" to "Data Traceability"
The core breakthrough of Imperium Chain, based on Monero ring signature and Zcash zk-SNARKs technology, lies in extending anonymous protection throughout the entire process of "transaction initiation - network propagation - on-chain storage", forming a "privacy protection network" that progresses layer by layer, and realizing that every transaction truly "comes and goes without a trace".
A-PoS + Consensus Mechanism: Anonymous Verification, Eliminating "Node Targeted Attacks" from the SourceIn the traditional PoS consensus, the identity of verification nodes is public, making them vulnerable to "targeted attacks" by hackers (such as paralyzing top nodes through DDoS attacks and bribing nodes to manipulate transaction verification). However, A-PoS+ (Anonymous Proof of Stake Plus) completely cuts off the connection between "node identity and transaction verification" at the verification layer through "cryptographic lottery + dynamic anonymous identity":
Random formation of verification committees: Through a cryptographic lottery algorithm (realizing "fairness + unpredictability" based on Zero-Knowledge Proof), the system randomly selects verification committee members from nodes staking AIS. The size of the committee is dynamically adjusted (50-200 nodes) according to the network transaction volume, with a term of 24 hours. The lottery process is fully on-chain verifiable, but the members' identities are only identified by encrypted addresses, and the outside world cannot associate them with real node operators.
Dynamic encrypted identity rotation: During the term of office, after a verification node completes the verification of 10 blocks, the system will automatically generate a new temporary encrypted identity (including a new public key and node communication key), and the old identity will become invalid immediately. Even if a temporary identity is accidentally exposed, it only corresponds to the verification behavior within a very short period of time, and the complete verification track of the node cannot be traced.
Anonymous rewards and accountability: If a node engages in malicious behavior (such as forging transactions and refusing to verify legal blocks), the system will lock and confiscate the AIS it staked through Zero-Knowledge Proof, but only announce the "anonymous address + confiscated amount" without disclosing the node's real information; on the contrary, the AIS rewards obtained by honest nodes will also be distributed to temporary encrypted addresses, which can only be withdrawn after multi-signature verification, further protecting the privacy of node operators.
Core value: Realize anonymity from the "source of verification power", avoid the risk of consensus network manipulation caused by node identity exposure, and let "decentralized verification" truly break away from the shackles of "node identity binding".
Dandelion++ Protocol: Transaction Propagation, Making "IP Traceability" ImpossibleThe "network-layer anonymity" of blockchain transactions has long been plagued by the pain point that "the IP initiating the transaction can be associated with the node IP". Hackers can reversely trace the real IP of the transaction initiator by analyzing the transaction propagation path between nodes (such as the "transaction fingerprint analysis" attack on Bitcoin). Imperium Chain introduces an optimized version of the Dandelion++ protocol to completely confuse the source of transactions through "dandelion-like propagation":
"Stem-Fluff" two-stage propagation:
Stem Phase: After a transaction is initiated, it first randomly selects a "relay node" (screened by the system based on node health and geographical dispersion to avoid single-node risks). The transaction information is only transmitted to this relay node in encrypted form, and a "one-time session key" is used during the transmission process. The relay node cannot decrypt the transaction content and is only responsible for forwarding.
Fluff Phase: After receiving the transaction, the relay node randomly selects 3-5 other nodes for broadcasting. The broadcasted nodes then each randomly select multiple nodes to spread, forming a "radial" propagation network. At this time, the transaction is decrypted and enters the verification process, and no one in the entire network can infer the "initial initiating node" through the propagation path.
Dynamic relay node pool: The system monitors the network status of relay nodes in real time. If a relay node has problems such as excessive delay or abnormal offline, a new node is immediately selected from the "standby node pool" to ensure the stability and anonymity of the "stem phase" propagation. At the same time, the probability of a single node being selected as a relay node is positively correlated with the amount of AIS it stakes, but the corresponding relationship between "staking amount and selection probability" is hidden through Zero-Knowledge Proof to avoid "high-staking nodes monopolizing the relay right".
Core value: Completely "decouple" the IP of the transaction initiator from the on-chain transaction. Even if hackers control some nodes, they cannot locate the source of the transaction through network traffic analysis, realizing the absolute security of "network-layer anonymity".
Mimblewimble Protocol Variant: Data Storage, Making "Historical Transaction Traceability" a FantasyTraditional blockchains (such as Bitcoin and Ethereum) store complete information of each transaction, including input, output, address, and amount. Third parties can restore the user's asset holdings and transfer tracks through methods such as "address clustering" and "transaction flow analysis". Imperium Chain develops a variant solution based on the Mimblewimble protocol to "prune and merge" on-chain data, retaining only the "core verification information" of transactions:
Transaction data pruning: Remove the "address information" from the transaction and only retain the mathematical verification relationship of "total input amount = total output amount + handling fee". Through Zero-Knowledge Proof, the verification node can confirm the legitimacy of the transaction (no over-transfer and no double-spending) without knowing the specific address.
Historical data merging: Every 100 blocks, the system automatically "merges and compresses" all transaction data in this interval - merging the "input-output" relationships of multiple transactions into an aggregated verification information of "total input - total output", and deleting the detailed data of individual transactions. The compressed data volume is only 30% of the original data, and the specific situation of a single transaction (such as the participants and transfer amount of a certain transaction) cannot be inferred from the aggregated information.
Optional encrypted data storage: If users need to retain "proof documents" for specific transactions (such as compliance certificates for cross-border transfers), they can store the documents in the DePIN decentralized storage network through encryption algorithms and only upload the "encrypted hash value" to the chain. When verification is needed later, the authenticity of the document can be confirmed through Zero-Knowledge Proof without exposing the document content.
Core value: Only minimal data that "can be verified but not traced" is retained on the chain. Even if a third party obtains the complete blockchain data, it cannot restore the user's transaction history and asset status, realizing the ultimate protection of "storage-layer anonymity".
