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 one of their autonomous agents (smart contract). Primary areas of concern are around loss of user funds, DoS, and total network shutdown.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, and in Obyte’s case, its DAG, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

In order to qualify for the reward of USD 50 000, the bug reported must be able to cause unrecoverable total network shutdown of the entire Obyte network or allow the unpermitted execution of transactions from accounts of other users without their private keys. All other critical bug reports are capped at USD 2 500.

Theft of yield/interest in this bug bounty program is considered Low.

All web and app bug reports must come with a PoC. All bug reports submitted without PoC will be rejected with instructions to provide PoC.

The web/app impacts of “Stealing User Cookies” and “Bypassing Authentication” are only accepted if they result in a loss of at least USD 1 000. The web/app impact of “Ability to execute system commands” is only accepted if the actions are done as root.

Payouts are handled by the Obyte Foundation directly and are denominated in USD. The payout can be completed in GBYTE, BTC, or OUSD.
