Censorship Threats

Users can leverage types of pluggable transports which alter the signature of each packet aiming to appear as normal unblocked traffic. IP blocking is generally avoided by running domain fronting bridges which will encrypt traffic as HTTPS requests to unblocked services like Azure or Cloudflare. Once they reach the unblocked service, the bridge will forward the request to the desired location. In the case of domain fronting, it becomes difficult for a state level actor to prevent the flow of all traffic to popular bridges without causing significant disruption to the general usage of the internet. 

Evading DPI Strategies

Although the Service Node network has no central points of failure, there are two significant censorship threats to the network, being harvesting attacks and deep packet inspection

IP and Packet Blocking

Users of decentralised blockchains are not required to provide digital or physical identifiers which helps users who lack identity or are being persecuted because of it but create vulnerability to Sybil attacks where a malicious actor produces numerous false identities and uses these identities to spam the network with requests. 

Denial of Service Attacks

When nodes operate in a trustless environment without a centralised leader enforcing rules, maintaining proper node behavior on the network becomes difficult. Although Service Nodes in Loki must hold the correct collateral requirement, they may choose to not route traffic or store data in their memory pools. Because this option is financially beneficial, a system of distributed flagging needs to be proposed to remove underperforming nodes.
