• NounsBR artwork is in the public domain.
• One NounBR is trustlessly auctioned every 15 minutes, forever.
• 100% of NounBR auction proceeds are trustlessly sent to the treasury.
• Settlement of one auction kicks off the next.
• All NounsBR are members of NounsBR DAO.
• NounsBR DAO uses a fork of Compound Governance.
• One NounBR is equal to one vote.
• The treasury is controlled exclusively by NounsBR via governance.
• Artwork is generative and stored directly on-chain (not IPFS).
• No explicit rules exist for attribute scarcity; all NounsBR are equally rare.
• NoundersBR receive rewards in the form of NounsBR (10% of supply for first 5 years).

The NounsBR Auction Contract will act as a self-sufficient NounBR generation and distribution mechanism, auctioning one NounBR every 15 minutes, forever. 100% of auction proceeds (ETH) are automatically deposited in the NounsBR DAO treasury, where they are governed by NounBR owners.

Each time an auction is settled, the settlement transaction will also cause a new NounBR to be minted and a new 15 minutes auction to begin.

While settlement is most heavily incentivized for the winning bidder, it can be triggered by anyone, allowing the system to trustlessly auction NounsBR as long as Ethereum is operational and there are interested bidders.

Regarding the NoundersBR veto right, the NounsBR DAO will follow the exact terms applied by Nouns DAO, as follows:

The proposal veto right was initially envisioned as a temporary solution to the problem of ‘51% attacks’ on the Nouns DAO treasury. While Nounders initially believed that a healthy distribution of Nouns would be sufficient protection for the DAO, a more complete understanding of the incentives and risks has led to general consensus within the Nounders, the Nouns Foundation, and the wider community that a more robust game-theoretic solution should be implemented before the right is removed.

The Nouns community has undertaken a preliminary exploration of proposal veto alternatives (‘rage quit’ etc.), but it is now clear that this is a difficult problem that will require significantly more research, development and testing before a satisfactory solution can be implemented.

Consequently, the Nouns Foundation (and in NounsBR case, its founders) anticipates being the steward of the veto power until Nouns DAO is ready to implement an alternative, and therefore wishes to clarify the conditions under which it would exercise this power.

The Nouns Foundation and NounsBR DAO considers the veto an emergency power that should not be exercised in the normal course of business. The NounsBR DAO will veto proposals that introduce non-trivial legal or existential risks to the NounsBR DAO , including (but not necessarily limited to) proposals that:

• unequally withdraw the treasury for personal gain
• bribe voters to facilitate withdraws of the treasury for personal gain
• attempt to alter NounBR auction cadence for the purpose of maintaining or acquiring a voting majority
• make upgrades to critical smart contracts without undergoing an audit

There are unfortunately no algorithmic solutions for making these determinations in advance (if there were, the veto would not be required), and proposals must be considered on a case by case basis.

NounsBR are generated randomly based Ethereum block hashes. There are no 'if' statements or other rules governing NounBR trait scarcity, which makes all NounsBR equally rare. As of this writing, NounsBR are made up of:

• backgrounds (2)
• bodies (16)
• accessories (24)
• heads (40)
• glasses (13)

NounsBR are stored directly on Ethereum and do not utilize pointers to other networks such as IPFS. This is possible because NounBR parts are compressed and stored on-chain using a custom run-length encoding (RLE), which is a form of lossless compression.

The compressed parts are efficiently converted into a single base64 encoded SVG image on-chain. To accomplish this, each part is decoded into an intermediate format before being converted into a series of SVG rects using batched, on-chain string concatenation. Once the entire SVG has been generated, it is base64 encoded.

The NounBR Seeder contract is used to determine NounBR traits during the minting process. The seeder contract can be replaced to allow for future trait generation algorithm upgrades. Additionally, it can be locked by the NounsBR DAO to prevent any future updates. Currently, NounBR traits are determined using pseudo-random number generation:

Trait generation is not truly random. Traits can be predicted when minting a NounBR on the pending block.

'NoundersBR' are a group of brazilian artists and entrepreneurs that initiated NounsBR. Here are the NoundersBR:

• @beautyandpunk
• @komesciart
• @QuijoteHorizon

Because 100% of NounBR auction proceeds are sent to NounsBR DAO, NoundersBR have chosen to compensate themselves with NounsBR. Every 10th NounBR for the first 5 years of the project (NounBR ids #0, #10, #20, #30 and so on) will be automatically sent to the NounderBR's multisig to be vested and shared among the founding members of the project.

NounderBR distributions don't interfere with the cadence of 15 minutes auctions. NounsBR are sent directly to the NounderBR's Multisig, and auctions continue on schedule with the next available NounBR ID.
