This document was last updated on 23rd December 2019. Previous versions of the Responsible Disclosure Policy can be found here.
Security is core to our values, and we value the input of security researchers acting in good faith to help us maintain high standards of security and privacy for our users and the Bitcoin SV blockchain. This includes encouraging responsible vulnerability research and disclosure. This policy sets out our definition of good faith in the context of finding and reporting vulnerabilities, as well as what you can expect from us in return.
We may modify the terms of this policy or terminate this policy at any time. We won’t apply any changes we make to these policy terms retroactively.
When working with us according to this policy, you can expect us to:
When conducting vulnerability research according to this policy, we consider this research to be:
You are expected, as always, to comply with all applicable laws.
If at any time you have concerns or are uncertain whether your security research is consistent with this policy, please submit a report through one of our Official Channels before going any further.
To encourage vulnerability research and to avoid any confusion between good-faith research and malicious attack, we ask that you:
To help us receive vulnerability submissions we use the following official reporting channel:
If you think you’ve found a vulnerability, please include the following details with your report and be as descriptive as possible:
Please encrypt all information that you send to us using our PGP key ([email protected]). This key is available from Public PGP Key Servers such as the MIT PGP Public Key Server. The PGP key has ID 7A20AB62 and fingerprint E8EB 970A 1C60 7DF0 822E 1388 F969 76FD 7A20 AB62. The PGP key is included in its entirety at the bottom of this page for your convenience.
A ‘bounty’ or reward may be payable for the responsible disclosure of vulnerabilities in accordance with our policy and ground rules, and provided that the Bitcoin SV security team is one of the original recipients of the disclosure.
The final amount is always chosen at the discretion of the reward panel, but the general guidelines below provides examples of the maximum rewards that may be payable based on the severity of the vulnerability that has been found. It should be noted that only vulnerabilities that are economically feasible will be considered e.g. 51% attacks on the network will be considered economically unviable.
|Description||Catastrophic impact on the network as a whole; network availability compromised; loss of funds||Impacts individual nodes; individual node crashes; potential for a loss of funds||Not easily exploitable; medium impact; no loss of funds||Not easily exploitable; low impact|
|Reward*||$100,000 USD||$50,000 USD||$10,000 USD||$1,000 USD|
*All rewards will be paid out in Bitcoin SV from CoinGeek Mining’s open source budget.
Our bug bounty policy focuses on the code base for Bitcoin SV and spans end-to-end: from soundness of protocols (such as the blockchain consensus model, the wire and p2p protocols, proof of work, etc.), protocol implementation and compliance to network security and consensus integrity. Classical client security as well as security of cryptographic primitives are also part of the policy.
Scope is limited to code contained in specified branches of the repository located at: https://github.com/bitcoin-sv/bitcoin-sv. Branches in and out of scope are specified by the branch name:
Branches in scope:
Branches out of scope:
Disclaimer: the scope of this policy is limited to those Operating Systems & hardware platforms for which binaries are released by the Bitcoin SV Node implementation team.
We define “resource exhaustion attack” as an exploit designed to consume large amounts of CPU, memory, bandwidth or storage resources whether by normal operation of the Bitcoin SV protocol or by intentionally crafting blocks or transactions with unusual behavioural characteristics.Bitcoin by design requires that miners competitively push the boundaries of resource limits to ensure ongoing growth in network capacity. As such default settings of various resource limiting features are intentionally defaulted to values which may not be considered safe under unusual situations. It is intended for operators of the Bitcoin SV software to choose and set these limits. Various other mechanisms, both technical and economic, are in place to discourage such attacks either by making them expensive to execute, by minimising their impact on the majority of network operations or by limiting resource usage with configurable consensus or policy limits.Resource exhaustion attacks, as defined, are out of scope for the bug bounty program.However, we acknowledge that there is value in documenting all possible attack vectors and will consider disclosures of such attacks for rewards in the “low” category and in exceptional cases in the “medium” category. Awarding of bounties in this category are subject to the following conditions:
For obvious security reasons it would not responsible for the Bitcoin SV team to publicly document known attack vectors. This necessarily requires a degree of good faith however it is strongly in the interest of the Bitcoin SV team to encourage such disclosures and build trust with the security research community through building a track record of making such bounty awards.
Please note, we do not want to receive any sensitive data during any disclosure, such as personally identifiable information (PII) or any data associated with private/public keys.
