We, the undersigned core developers of OpenBazaar, have decided with consensus on the following on November 4th, 2014: Because of the facts that: (1) Developers can be malicious Our threat model involves powerful agents at play. These can include malicious governments who have the ability to issue secret warrants legally requiring developers to take certain actions. We therefore follow a trust-but-verify model in all our development process. As such, certain developers of the project may in the future be legally required to perform actions that they do not agree with, without the ability to communicate this fact to others. Through multisig, we are requiring at least one more developer to perform a check on financial decisions as a safety-net. (2) Mistakes happen We are human and often make mistakes. This can include lost wallet keys, or destroyed laptops. Multisig will allow us to migrate our funds in case one developer loses their keys. We also sometimes make transactions that may be incorrect. A second pair of eyes is good to make sure we don’t burn our funds or we don’t send them to the wrong third party. (3) Developers can become unavailable Developers may become unavailable for various reasons such as accident or death. We do not want to depend on one individual for all our funds. In case of unavailability, multisig allows us to move our funds to a new address. (4) Dictatorship is evil We take team decisions with consensus. However, sometimes consensus cannot be reached. We have never had this problem in our team yet, but it is bound to happen in the future. In cases where consensus cannot be reached, an individual developer should not have the power to act solely as a dictator and enforce their opinion. Multisig requires at least one more party to consent. This acts as a safety net. (5) Transparency is good We believe in a transparent development model. All our code is open source. We interact with the community through public chat on IRC, on a public subreddit, and in forums, all viewable by anyone. We plan features and submit bug reports through GitHub issues, which are public. Anyone is able to criticize us through these channels directly, even pseudonymously. As of Beta 3, we are also making all all-hands developer video calls publicly available through live streaming, and they are recorded for future reference. We wish to be held accountable for our actions, and we invite the criticism of the community. In this direction, as we are funded through donations, we believe the public should know exactly how much money we have and where and when exactly it is spent. By publishing our multisig address, we submit our financial records to public scrutiny. Now, therefore, we are announcing the following: (1) Ownership of public keys Each of us controls one of the following public bitcoin keys. We are providing bitcoin signatures as proof that we are in control of each.

Any funds donated to the old address will be immediately transfered to the multisig address. We will make all our organizational payments directly from our multisig address. We vow to publish the following information for every transaction originating from our project multisig address from now on:

  • The recipient bitcoin address
  • The date of the transaction
  • The recipient actual name or company name
  • The reason for the expenses

In case of conversion to fiat currency, we will state the above data for the recipient of the converted fiat currency. We invite the public to verify our GPG signatures on the above announcement.
