View impacts in scope Program Overview Obyte is a distributed ledger based on directed acyclic graph (DAG) and is without middlemen. Unlike centralized ledgers and blockchains, access to the Obyte ledger is decentralized, disintermediated, free (as in freedom), equal, and open. The Obyte Foundation is interested in securing their network, their core library, their GUI wallet, and some of their autonomous agents (smart contracts that operate completely independently). Primary areas of concern are around loss of user funds, DoS(not DDoS), and total network shutdown. Primacy of Impact vs Primacy of Rules Obyte adheres to the Primacy of Rules, which means that the whole bug bounty program is run strictly under the terms stated in this page. KYC not required No KYC information is required for payout processing. Proof of Concept Proof of concept is always required for all severities. Responsible Publication Category 3: Approval Required Prohibited Activities Default prohibited activities Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet Any testing with pricing oracles or third-party smart contracts Attempting phishing or other social engineering attacks against our employees and/or customers Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks) Any denial of service attacks that are executed against project assets Automated testing of services that generates significant amounts of traffic Public disclosure of an unpatched vulnerability in an embargoed bounty Any other actions prohibited by the Immunefi Rules Feasibility Limitations The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity. Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
