🧪 Mad Science Project Idea: Decentralized Social Rollup

What is an Mad Science Project Idea?

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

The OP Stack makes it possible to easily spin up new rollups. Can you use the OP Stack and your favorite social protocol (Lens? Farcaster? Your own?) to create a social rollup? Or how about a decentralized backend for a web2 social media service?

Possible Features

• Create an OP Stack chain that runs a decentralized social media protocol.
• Create an OP Stack chain that acts as the backend for a web2 service.

📝 Draft Project Idea: Plasma DA

What is a Draft Project Idea?

A Draft Project Idea is a concept for a project within the Optimism ecosystem that is generally considered valuable but has not yet been fleshed out into a clearly defined product. Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

It's the return of Plasma! It's possible to hack the OP Stack so that data is published to a separate data availability layer instead of being published to Ethereum. Only hashes of that data would be published to Ethereum. You could then implement a challenge game on top of this to create a full-blown plasma protocol.

Plasma protocols like this are highly valuable because they provide extremely cheap data availability options while still providing good enough security properties for many use-cases. A design for a generic plasma protocol for the OP Stack would be very useful for the OP Stack ecosystem.

Possible Features

• Post data to any data availability provider
• Post hashes to Ethereum
• Define a challenge game that is compatible with the OP Stack

🔴 Ecosystem Project Idea: Attestation-Based Access Gating System

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The AttestationStation is a simple and unified way to make attestations on OP Mainnet, OP Goerli, or any other OP Stack-based chain.

You can use the AttestationStation to create a generic system that allows developers to gate access to product features depending on the attestations that a user has. Ideally this looks like some sort of SDK and/or server that allows app developers to specify relatively complex sets of attestations that users need to have before they can access a feature.

Possible Features

• Allow developers to specify complex attestation-based conditions to unlock features in their products.

Impact

• Developers could have more fine-grained control over who can access their product
• Communities can have complex but programmatic conditions for members

📝 Draft Project Idea: Unified Block Explorer

Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

Optimism's Superchain model aims to create a network of blockchains that feel like one unified blockchain. One important component of the Superchain is the user interface (block explorers). Currently, block explorers are tied to one specific blockchain. Could we build a block explorer that seamlessly explores/indexes multiple OP Stack chains at the same time?

Possible Features

• Block explorer as a search engine
• Aggregate data from multiple chains

🔴 Ecosystem Project Idea: Global Passport NFT

Possible Features

• View total MEV extraction over time
• View sources of MEV
• Track MEV transactions

Impact

• MEV is everywhere and highlighting MEV locations makes it easier to reduce
• MEV can be repurposed as income for a chain, understanding total MEV means understanding chain profitability

Resources

• Flashbots MEV explorer

---

Summary

Create a mechanism that gives users an incentive to use OP Mainnet that is generally sybil resistant. Ideally, each new user that someone gets to use OP Mainnet should result in an referral payout. You'll need to figure out how to make this sybil resistant and how to track referrals so they can be distributed. You might want to look into the AttestationStation as a way to handle sybil resistance.

Possible Features

• Allow users to register for some sort of referral link.
• Allow users to be rewarded when accounts they refer hit certain thresholds.
• Make the protocol sybil resistant.

📝 Draft Project Idea: Indexing Chains

What is a Draft Project Idea?

Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

It is possible to configure an OP Stack chain to operate without a Sequencer and to simply index data from the parent blockchain. We typically refer to these chains as "utility chains". You can use this concept to create a blockchain that indexes the parent chain in a verifiable way.

Possible Features

• Create an OP Stack chain that indexes useful data from a parent chain
• Create a smart contract on the parent chain that accesses data from this indexing chain

✨ Contribution Opportunity: Convert Echinda tests to Forge invariants

What is a Contribution Opportunity?

A Contribution Opportunity is a concrete task that you can work on to contribute to the Optimism Collective.

---

Summary

The smart contracts for Optimism’s upcoming Bedrock launch includes a suite of Echidna tests which use Echidna for property testing. These contracts also have a suite of Forge invariant tests. In order to standardize tooling, OP Labs is looking for contributors to help convert the Echidna tests into to Forge invariant tests.

Please refer to the corresponding GitHub issue for more information.

Impact

Standardization is important to making sure that we’re covering every possible case with our invariant test suite and that we’re not missing anything because tests are split between two different frameworks.

Resources

• Bedrock
• Echidna

🧪 Mad Science Project Idea: Prediction Market Framework for Everything

What is an Mad Science Project Idea?

Possible Features

• Create an OP Stack chain that acts like a prediction market for everything.

🔴 Ecosystem Project Idea: ATST Data Duplicator

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The AttestationStation is a central repository for attestations on OP Mainnet. One of the primary challenges currently facing the AttestationStation is the need to bootstrap the system with high-quality attestations. Luckily, blockchains already have an enormous amount of useful data that can be converted into attestations.

Some examples of existing blockchain data that can be converted into productive attestations are:

• Addresses that were part of the initial ETH genesis allocation
• Addresses that have held some NFT for more than X amount of time
• Addresses that have donated to GitCoin rounds
• Addresses that have received POAPs from important events

Converting this information into attestations makes it more accessible to developers and improves the quality of data in the AttestationStation generally. It would be valuable to have a project that can import this data into the AttestationStation in a verifiable way. Here, "verifiable" means that another user can replicate the process that was used to generate the attestations to confirm that all of the attestations were generated properly. That user can then trust that the attestations are correct and can begin to use them in their own applications.

Possible Features

• Specify queries or scripts that pull blockchain data and convert that data into attestations
• Allow developers to easily reproduce the queries/scripts to verify the attestations
• Consider creating a system that makes it easy to do this for arbitrary queries.

🔴 Ecosystem Project Idea: Events Ticketing Application

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The AttestationStation is a simple and unified way to make attestations on OP Mainnet, OP Goerli, or any other OP Stack-based chain.

You can use the AttestationStation to create a ticketing application for events by allowing anyone to register an event, issue tickets, or revoke tickets. Everything should be represented as an attestation.

Possible Features

• Allow organizers to register an event, and store event details onchain via attestations.
• Allow organizers to issue tickets via attestations.
• Allow organizers to revoke tickets via attestations.
• Allow organizers to verify tickets by scanning a QR code.

Impact

• Ticketing data is very useful for other applications using the AttestationStation

---

Summary

Blockchain faucets tend to be a bit of a pain, but maybe that's just because we haven't experimented enough with what's possible! Try creating a faucet that has a better incentive model than the traditional faucet. Maybe you could create a faucet that can deploy smart contracts for you but won't actually give you ETH.

Possible Features

• Create a testnet faucet with a novel distribution mechanism.

📝 Draft Project Idea: Alternative Solidity Compiler

What is a Draft Project Idea?

A Draft Project Idea is a concept for a project within the Optimism ecosystem that is generally considered valuable but has not yet been fleshed out into a clearly defined product. Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

Solidity is the primary programming language for most EVM-based applications. It currently has a single compiler, solc. Just like client diversity is important for the robustness of Ethereum, compiler diversity is important for the robustness of applications built on top of Ethereum. By introducing new compilers we can eliminate single points of failure and create competition that improves the Solidity experience for everyone.

Impact

• Alternative compilers remove the single point of failure in the current codebase
• Alternative compilers can improve the compilation process and the development experience
• Alternative compilers may be able to make optimizations that the current Solidity compiler cannot.

Resources

• Solidity
• solc

Possible Features

• Build on top of other indexers or build your own
• Create an algorithm that scores user impact onchain

📝 Draft Project Idea: Fault Proof Framework

What is a Draft Project Idea?

A Draft Project Idea is a concept for a project within the Optimism ecosystem that is generally considered valuable but has not yet been fleshed out into a clearly defined product. Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

A fault proof is a mechanism that proves that a given program with some agreed-upon starting state and agreed-upon inputs did not generate some proposed output. Combined with an optimistic output proposal mechanism, fault proofs are an effective way of scaling the computational abilities of a smart contract by limiting onchain interactions to only the case where a proposed output is invalid.

Several different fault proof systems exist already and more will be developed as time goes on. In general, the overall structure of a fault proving system tends to be identical except for specific areas. We believe that these key areas can be abstracted away into modules in a larger fault proving framework that would make it possible to reuse code from across the ecosystem and reduce the amount of duplicated work.

A basic model for a framework like this would contain the following components:

• A "program" that consists of compiled bytecode for some machine architecture
• A "program executor" that executes a program bytecode for a given machine architecture with some given state and generates an execution trace in some standardized format (follows a standard interface)
• A "dispute game" that resolves disputes over any arbitrary array (OP Labs is already working on this)
• A "smart contract opcode executor" that can execute any single opcode within the specified machine architecture onchain (follows a standard interface)

Fault proof developers then only need to implement the "program executor" and the "smart contract opcode executor" for any given machine architecture while the rest of the logic is handled by the framework. For example, it should be easy to slot in a MIPS fault proof or a RISC-V fault proof within this system without having to re-implement everything.

Impact

A fault proof framework would have a significant impact because:

• It would allow developers to more easily build proofs for new machine architectures
• It would allow projects to take advantage of client diversity by targeting different architectures

---

Summary

The AttestationStation is a simple and unified way to make attestations on OP Mainnet, OP Goerli, or any other OP Stack-based chain.

You can use attestations as a way to show that two users have met each other in person. This would be a great application for conferences where people often need to share contact information to stay in touch in the future. Imagine something along the lines of sharing business cards. Each business card could have its own set of contact information that will be shared with the recipient.

Possible Features

• Allow users to create attestations that signal that the users have met in person.
• Allow users that have met in person to share contact information.
• Combine this with events so that users can show that they've met each other at X different events.

---

Summary

The AttestationStation is a central repository for attestations on OP Mainnet. One of the primary challenges facing the AttestationStation today is that complex queries against the AttestationStation can be hard to execute. Developers are looking for easy, scalable ways to index the AttestationStation so that they can cheaply query the graph of attestations. The ideal AttestationStation indexer is efficient, easy to run, robust, and provides easy querying access to the full graph of attestations.

Possible Features

• Allow developers to easily run the indexer.
• Allow developers to quickly query the ATST graph.

🧪 Mad Science Project Idea: Trigger L2 contracts with L1 events

What is an Mad Science Project Idea?

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

The OP Stack makes it possible to trigger actions on L2 based on things that happen on L1. One powerful mechanism that an OP Stack chain could introduce is the ability to register "hooks" that are automatically triggered when certain events are emitted on the L1 chain. Doing so would require modifying the derivation layer of the OP Stack in a manner similar to the example modification found within the OP Stack documentation.

An ideal hook system would allow any address to register a hook via a smart contract on L2 by providing the L1 address, an event filter, and a function to be triggered whenever the event is emitted. You may have to come up with a fee mechanism that accounts for the cost of checking for events each time a new block is introduced. It may also be necessary to supply a maximum number of hooks that can be registered at any point.

Possible Features

• Allow users to register new hooks with an L2 smart contracts
• Modify the derivation layer to trigger L2 contracts based on the registered hooks
• Charge a fee whenever a hook is checked
• Charge a fee whenever a hook is executed (to pay for gas)

Resources

• OP Stack
• Derivation layer modification example

🔴 Ecosystem Project Idea: L2 NFT Gift Cards

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

Bridging UX today is a blocker to more people onboarding onto L2s. We’ve heard this especially for NFT users, who tend to be less technical and daring with random interfaces that take their tokens. Gift cards are a great way to get someone into the L2 ecosystem.

From the Bridge Pass Mirror post:

What if we took the gift card metaphor to make collectible NFT editions that, when minted, automatically bridge funds to an L2?

Instead of bridging to L2 through a boring “swap” UX, what if users could buy a cool looking NFT! Under the hood, the purchaser receives the collectible NFT on L1, while the funds are bridged and made available on L2.

Create a gift card NFT that contains a special note for the recipient and can be redeemed for a certain amount of ETH or OP on OP Mainnet. The gift cards could live either on L1 or on L2.

Possible Features

• Giftcard marketplace”-like interface, with maybe just a couple of highly desired collections (motorheadz?)
• Allow users to create a gift card by writing a message and attaching some ETH or OP.
• Allow users to send the gift card to addresses on Ethereum or OP Mainnet.
• Allow recipients to access the gift card, see the special message, and redeem the gift card for its value.
• Buy an NFT, autobridge from L1 (or wherever you have funds)
• If the gift card is sent on Ethereum, redeeming should perform a deposit into OP Mainnet.
• If the gift card is sent on OP Mainnet, redeeming should simply transfer assets to the recipient.

Impact

• This can onboard new NFT users by just sneaking bridging under the hood.
• It can be a fun way to make OP NFTs go viral — by gifting!

🔴 Ecosystem Project Idea: ATST Schema Reputation System

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The AttestationStation (ATST) is a central repository for attestations on OP Mainnet. The ATST is transitioning to use the Ethereum Attestation Service (EAS) standard which introduces schemas that attestations can follow. EAS schemas are defined as Solidity structs and can therefore allow attestations to contain arbitrarily complex data structures.

One problem with EAS schemas today is that it's often unclear which schema a developer should use for a given type of attestation. Sometimes a schema already exists that a developer can use, sometimes no schema exists, and sometimes multiple potential schemas exist.

It's important for developers to be able to easily understand:

• What schemas already exist for a given type of attestation
• Which schema to use for a given type of attestation

We propose solving these problems with the introduction of a "schema reputation system" with the following features:

• Accounts can attest that a given schema is the "correct" schema to use for a given task
• Users can explore the list of "correct" schemas on a web interface
• The web interface applies a default algorithm to surface "correct" schemas
• The web interface allows users to apply alternative algorithms to surface "correct" schemas

A simple proposal for a default algorithm would be to use attestations from reputable organizations in the space. Although this isn't totally decentralized, it provides a strong starting point. If the application is designed carefully, the default algorithm can easily be updated and improved in the future to be more decentralized. Furthermore, if the web interface allows users to include their own algorithms, then users can experiment with better mechanisms on behalf of the project.

Impact

A schema reputation system is highly impactful because it allows developers to coordinate on standardized schemas for specific tasks. Standardized schemas means that multiple applications can work from the same dataset and can easily find attestations of a given type without fear that data will be fractured across different data structures. This system also gives developers confidence that they're using a standard that others will be able to easily parse.

🔴 Ecosystem Project Idea: ATST Citizenship Algorithm

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The AttestationStation is a central repository for attestations on OP Mainnet. One of the main usecases for the AttestationStation is to establish Citizenship for Optimism's one-person-one-vote Citizen House.

Using the AttestationStation, define a highly sybil resistant algorithm that uses attestations to select the set of Citizens at any given time. A good Citizenship algorithm should identify members of the Optimism Collective who contribute actively to the Collective.

Alternatively, if the attestations required to create such an algorithm do not exist yet, create a list of proposed attestations that would make such a list possible. For example, if attestations that identify the addresses of OP Labs employees would be useful, you can propose this as a requested attestation.

Possible Features

• Define an algorithm that selects Citizens.
• Write a list of proposed attestations that would make Citizenship algorithms possible.

✨ Contribution Opportunity: Bedrock Contracts Architecture Diagram

What is a Contribution Opportunity?

A Contribution Opportunity is a concrete task that you can work on to contribute to the Optimism Collective.

---

Summary

The smart contracts for Optimism's upcoming Bedrock launch are now code-frozen. Currently, our existing architecture diagrams for the Bedrock smart contracts are out of date. OP Labs is looking for a contributor to create a high-quality architecture diagram of the Bedrock smart contracts that would make it easy for someone to understand how the contracts interact with one another.

Impact

Architecture diagrams help developers and OP Stack chain deployers understand how the various smart contracts within the Bedrock codebase interoperate.

🔴 Ecosystem Project Idea: OP Stack Chain Registry

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

The OP Stack is the open source software stack that powers the Optimism Collective. A core part of this stack is dedicated to the software for spinning up L2 blockchains like OP Mainnet and Base.

One problem facing the OP Stack today is the ability to easily resolve everything about an OP Stack chain, including contract addresses and chain configuration. All of this information is available within smart contracts on L1, but the missing piece is a smart contract registry that allows chain deployers to register their deployments for easy off-chain discovery. This would simplify much of the existing off-chain infrastructure and code that's currently responsible for this task.

The OP Stack Chain Registry should be a simple smart contract on L1 with the following features:

• A user should be able to "claim" a deployment name by sending a transaction that includes a string name and an address admin
• The admin of a given deployment should be able to set keys in a mapping of string names to addresses
• For simplicity, it should be possible to set multiple names to addresses in the same transaction
• For simplicity, it should be possible to query multiple addresses by their names in the same call
• This contract should live in the /periphery folder of the contracts-bedrock package within the Optimism Monorepo
• A hardhat task should be added to the /tasks folder of the contracts-bedrock package for setting this mapping automatically based on a given deployment folder

Impact

The OP Stack Chain Registry will make it possible to easily query all of the required contracts for a given OP Stack chain deployment. This will significantly reduce the complexity of querying these addresses off-chain.

✨ Contribution Opportunity: Review Bedrock contracts

What is a Contribution Opportunity?

A Contribution Opportunity is a concrete task that you can work on to contribute to the Optimism Collective.

---

Summary

The smart contracts for Optimism’s upcoming Bedrock launch are currently code frozen and not accepting modifications to operating logic. However, there’s still a need for reviewers to look over the code for opportunities to improve comments and tests. Review can also help spot areas for future improvements when the code begins accepting logic contributions again, including gas optimizations and overall structural simplifications.

Output for this project depends on the exact type of review performed but might look like:

• A PR that adds comments where missing
• A PR that adds additional tests where missing
• A detailed document that describes areas where comments/tests could be added
• A detailed document that describes areas where gas usage could be optimized
• A detailed document that describes areas where logic could be simplified

Impact

Optimism’s smart contracts form the backbone of the OP Stack. Simplifications, clarifications, and testing improvements make the OP Stack codebase stronger and safer for users of the Stack.

🧪 Mad Science Project Idea: Generalized "Airline Miles" Rollup

What is an Mad Science Project Idea?

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

The OP Stack makes it possible to easily spin up new rollups. A common use-case pitched for crypto is bringing rewards points onchain. However, this tends to be too expensive on blockchains like Ethereum. To solve the cost problem, you could create a rollup entirely dedicated to rewards points. You could even create a framework for easily spinning up rewards programs hooked up to individual rollups.

Possible Features

• Create an OP Stack chain that manages rewards points.
• Create a framework for launching OP Stack chains for rewards points.

📝 Draft Project Idea: Stop Snoozing!

What is a Draft Project Idea?

A Draft Project Idea is a concept for a project within the Optimism ecosystem that is generally considered valuable but has not yet been fleshed out into a clearly defined product. Draft Project Ideas may be converted into Ecosystem Project Ideas as they are explored further and more thoroughly specified.

---

Summary

Have a hard time waking up every day? Need something to keep you accountable? Introducing: Stop Snoozing!

Stop Snoozing! is a concept for a simple smart contract application that incentivizes you to wake up every day before a specified time. You can use bokkypoobah's Solidity DateTime library to make sure that a transaction is triggered on a set schedule within a certain time range. Users can put some ETH or ERC20 tokens up as stake that will be taken away if the transaction isn't sent on time. Easy!

Possible Features

• Allow users to easily set up a wakeup schedule
• Allow users to have a different wakeup schedule on different days of the week
• Allow users to put up some stake in ETH or ERC20 tokens
• Require users to trigger a transaction every day according to the wakeup schedule
• Take away the stake if the user fails to trigger the transaction

Impact

• Stop Snoozing! is a fun application that gets users familiar with making transactions every day
• Waking up is hard, but it's easier when you have a strong incentive to do so!

Resources

• Solidity DateTime library

🧪 Mad Science Project Idea: Doom as an OP Stack Chain

What is an Mad Science Project Idea?

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

The OP Stack makes it possible to easily spin up new rollups with custom execution environments. Although you could probably put Doom on a blockchain, why not create a blockchain that is Doom?

Doom Chain would involve hacking the execution layer to replace the EVM with an emulator of some system running Doom. Transactions in the system would then represent inputs to the system. Running Doom demo files should be a good test of this hack.

Possible Features

• Be able to play Doom in a browser where each input is actually a transaction to an OP Stack chain.
• Be able to run Doom demo files as an automated series of transactions to the Doom Chain.

Impact

• Doom is a great game
• OP Stack community would learn a lot about the process of modifying the execution layer
• You would get clout for SURE

Foundation Mission Request: Code of Conduct Enforcement Solution

Foundation Mission Request – Code of Conduct Enforcement Solution

• Foundation Mission Summary: Code of Conduct Enforcement Solution
• S4 Intent: Improve Governance Accessibility
• Proposal Tier: Ember
• Baseline grant amount: 50k OP
• Should this Foundation Mission be fulfilled by one or multiple Alliances: May be One or Multiple
• Optimism Foundation point-of-contact: Justine (@justine-hy)
• Submit by: June 28th at 19:00 GMT
• Selection by: July 13th at 19:00 GMT

---

How will this Foundation Mission (RFP) help accomplish the above Intent?:
A Code of Conduct went into affect in December 2021. The Code of Conduct is critical to maintaining a healthy governance community that all delegates feel welcome engaging in, thereby increasing the accessibility of Optimism governance.

The Foundation currently plays and administrative role in processing Code of Conduct violation reports. The Foundation is not an arbiter and does not adjudicate whether violations occurred, but the community has expressed interest in a more rigorous enforcement process. Some delegates have also expressed that they are uncomfortable voting on Delegate Suspensions.

Given that we are moving towards further decentralization, we don’t believe the Foundation should temporarily implement and administer an onerous governance process around adjudication. However, we welcome suggestions for alternative methods of enforcing the Code of Conduct that reduce or eliminate the Foundation’s role in the process while also minimizing governance overhead.

What is required to execute this Foundation Mission (RFP)?
A comprehensive plan to replace the Foundation in the Code of Conduct enforcement process that can be piloted in Season 4

• Proposed solutions should align with the principles outlined in our Working Constitution.
  • Governance minimization
  • Forkability
  • Anti-plutocracy
  • Impact = profit
• The proposed solution should account for a future where the Code of Conduct may be enforced by both the Token House and the Citizens’ House
• We are intentionally leaving the design space open for this solution. Proposals should specify the design of the system. Service providers may suggest their own solutions. If a service provider is not required to implement the solution, the designer of the proposal will receive the reward.

Please list the critical milestone(s that should be tracked to determine if you should receive your grant in one year:

• Implementation of solution by the end of Season 4

How should the Foundation measure progress towards this Foundation Mission (RFP):

• Successful processing of Code of Conduct violation reports
• Delegate feedback on process

How should badgeholders measure impact upon completion of this Foundation Mission (RFP)?

• Delegate feedback on process
• Reduction in Foundation time and overhead spent on Code of Conduct violations

🔴 Ecosystem Project Idea: OP Mainnet Gas Fee Tracker

What is an Ecosystem Project Idea?

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

Tools like ethgasstation help users understand the current transacting landscape on a blockchain. Currently, the best available tool for understanding the cost of using OP Mainnet is l2fees.info which only displays spot fees and does not show historical fees or the fees for using popular applications.

Possible Features

• Display showing the current cost of transacting on OP Mainnet using common transaction types as reference points. Ideally these common transaction types include basic transfers, ERC20 transfers, swaps, and a series of transaction types pulled from popular apps on OP Mainnet.
• Display historical gas prices on OP Mainnet to show how gas prices have changed over time.
• Display the users and applications that are using the most gas on OP Mainnet over certain specified time ranges (1d, 7d, 30d, all time).

Impact

• Users would have a better understanding of OP Mainnet fee behavior

🧪 Mad Science Project Idea: Conway's Game of Life Onchain

What is an Mad Science Project Idea?

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

Conway's Game of Life is a classic cellular automaton with straightforward rules. It should be possible to implement the Game of Life in a smart contract either on OP Mainnet or on a custom OP Stack chain. Can you make it happen?

The Game of Life is a tick-based simulation. At each tick, a new system state is computed and the simulation updates. Consider using the mechanism introduced by Ticking Optimism to create an OP Stack chain that automatically triggers an update function whenever a new L2 block is produced. This would make the simulation update in real time without the need for transactions to update the simulation state.

Possible Features

• Allow users to spin up their own Game of Life system on chain
• Allow users to initialize the Game of Life board with a starting state
• Allow users to start the simulation by sending a transaction
• Allow users to see the simulation progress with each tick
• Allow users to pause the simulation or reset it to start over

🧪 Mad Science Project Idea: Onchain Movie

---

Summary

The OP Stack makes it possible to easily spin up new rollups. You could make an entire rollup that just exists to host a single movie. It's not clear why you would do this, but that's the point of Mad Science Project Ideas. Have fun!

Possible Features

• Create an OP Stack chain that hosts a movie.
• Allow people to add comments or reviews about the movie.
• Create a custom video player that downloads the movie.

🔴 Ecosystem Project Idea: TokenList.org-Style Attestation List

An Ecosystem Project Idea is an idea for a project that someone could build within the Optimism ecosystem. As opposed to an Ecosystem Concept or an Ecosystem Idea, an Ecosystem Project is generally more fleshed out and corresponds to a relatively clear product to be built.

---

Summary

TokenList.org is a website that allows users to publish and discover lists of tokens maintained by teams and projects. These lists of tokens make it possible for teams to signal the legitimacy of certain tokens and help users filter out spam. The AttestationStation needs a similar type of "Attestation List" specification and website that helps users understand which attestations/schemas are appropriate to use for which use-cases.

Possible Features

• An instance of an attestation list following a standard JSON schema and can be hosted publicly on ENS, IPFS, or HTTPS.
• Context on what attestation lists are
• Directions on how to validate that a schemas follow the proposed standard
• Directions on how to author a attestation list
  • List data
    • List URL
    • List Name
    • List version
    • Link to the official homepage of the list manager
  • Attestation data
    • Attestation name
    • Attestation author
    • Attestation key
    • Attestation value
    • Attestation image
    • Attestation description
• Directions on how to deploy an attestation list
• Examples of what a attestation list looks like

🧪 Mad Science Project Idea: Crowdfunding Rollup

A Mad Science Project Idea is an idea for a project within the Optimism ecosystem that may not have clear value but is generally cool as heck. Mad Science Project Ideas make great hackathon projects and tend to be a great way to explore Optimism, OP Mainnet, and the OP Stack.

---

Summary

The OP Stack makes it possible to easily spin up new rollups. You could make an entire rollup dedicated to crowdfunding campaigns, like a decentralized Kickstarter! Although you could definitely do this on an existing EVM chain, it might be cheaper for end-users to do this on a custom rollup.

Possible Features

• Allow users to deposit funds from another L2 or from Ethereum.
• Allow users to view projects that need crowdfunding.
• Allow projects to register as needing funding.
• Allow users to fund projects.
• Allow projects to set different funding parameters.
