F8: Open Source Development Ecosystem

Currently there is no opensource component that allows developers to interact with web wallets like Nami from .Net C# in Blazor WebAssembly

Currently the .NET Library, CardanoSharp, lacks appropriate support for deserialization of Cardano CBOR serialized transactions.

There is no high quality WordPress plugin for receiving ADA payments. 1/4 of all websites are built on WordPress, more than 2M on Laravel

There is no easy way to create DAOs on Cardano. We need open source community focused tooling that enables collaboration.

Cardano Lacks Simple Multi-Signature Wallet Applications.

Tipping URLs are cool, but it adds friction for transactions. We could have a better solution for that.

No incentives to provide automation tools, no provision of open source training or communication of what open source in Cardano entails.

Transactions for sending assets to many addresses will incur cumulative transaction fee unless batched together into one transaction.

Open sourced wallet projects have the potential for any SPO to offer and host (submit-api) a branded wallet for their delegators.

The Cardano ecosystem does not have a native C++ library which isolates Cardano from one of the largest open-source developer communities.

Cardano-serialization-lib is one of the top projects in the ecosystem used by almost all dApps & needs to be updated for the next hardfork

Currently, there exist few tools & software built for ARM-based computers making it hard for developers to build and use existing software.

The tools for Python developers to build on Cardano are currently limited and existing libraries need updating to wrap recent features.

There's a great deal of value locked in the data processed by Cardano and its ecosystem. How to extract it and make it available to all?

There is no common libraries to help C++ Developers build on Cardano.

Funding from Project Catalyst requires several months before funds are available. Critical community initiatives need faster funding.

Same things get discussed over and over again, nothing gets done. People have no mandate to drive change. No room for leadership to emerge.

The Catalyst Community needs open spaces to network and connect ideas and projects as well to discuss and participate in Catalyst governance

Many projects rely on an IOHK tool called cardano-db-sync. This means that when an issue is found in db-sync, the many projects are affected

DAOs on our Next-gen DAO collaboration platform needs strong traceability for governance changes and open-source capture of their charters

There are not enough project based learning (PBL) formats available for DEVs to become blockchain DEVs and deliver on the work ahead.

Flutter is the fastest growing mobile app developer community but currently there's no Flutter library support in the Cardano ecosystem.

Connecting UN frameworks like the SDGs to Proposals require analyses + evaluation. Support our research work in Fund 8 as in Fund 6.

Cardano needs a wallet with robust handling of multisig for enterprise use cases and for DAOs

Cardano needs to build bridges with more Web3 Tools that allow for decentralized collaboration.

LATAM Cardano Community participates proactively in building the Cardano Ecosystem without ensured and sustainable access to resources

With the current supply chain shortages, previously low cost devices are becoming too expensive to source.

To ensure decentralization, we need to make it easy for users and developers to run full node and archive nodes of Milkomeda

Cardano was designed to support secure smart contracts. Yet, testing, auditing, and even designing Cardano dApps involve serious challenges.

Often the seller of a CNFT does so to purchase another NFT from the same collection. This results in unnecessary fees & lost opportunities.

There is currently no standard and commonly used tool that can verify NFTs as real

Cardano open-source funding is less than $25m. We need other major donors in & out of Cardano to accelerate open-source funding and support.

PHP developers are missing tools to fully enjoy Blockfrost.io, a service that provides free and public Cardano API to developers.

Stateful Plutus smart contracts (DeFi) are difficult to implement due to Cardano’s current transaction size parameters (16kb Tx size limit).

Plutus developers don't have a standard open source contract tooling required to quickly build, test and simulate their smart contracts.

Video games requiring real-time 3D procedural generation have almost no options available, especially free and open source.

Creating robust Catalyst proposals can be difficult. Connection with existing structures and frameworks is time consuming.

Reference inputs (CIP-31) will address Cardano's "concurrency problem" but there are no guidelines on how best to implement this feature.

Lets say we got a reddit to run by ourselves. How would we change it in the spirit of Cardano?

Project Catalyst turns economic power into innovation power by using the Cardano Treasury to incentivize and fund community-approved ideas.

Funds Overview

When a proposal is ‘Approved’, it means it received enough support to receive funding (at least 1% of the total registered voting power voted ‘YES’). But only those proposals that most people say 'YES' to get money first until there's no funding left in that category.

Meets all approval criteria; the highest ‘YES’ result gets funding first until the remaining budget is depleted in the category and unable to fully fund the next approved proposal. If the amount requested by a proposal is larger than the remaining category amount at any point, it is skipped.


Proposals that did not meet criteria for approval and were not eligible for funding. Each proposal needs to get enough 'YES' votes equal to 1% or more of total registered voting power in a funding round in order to be approved.

Proposals that met approval criteria but whose budgets exceeded the remaining category budget. Some 'Not Funded' proposals can get second change via 'Sponsored by Leftovers' category. Proposals can be approved but not funded due to lack of funding budget availability in a relevant category.

At least 1% of the total registered voting power must vote ‘YES’ on a proposal. In Fund11, there was ₳4,535,989,461 as a total registered voting power as accounted for by the snapshot. To be accepted (become an ‘approved proposal’ as well as be eligible for funding), a proposal must be voted by at least 0.01 * ₳4,535,989,461 = ₳45,359,894.61. ‘ABSTAIN’ votes do not count towards the acceptance threshold of 1%.

Proposals are ranked by the highest ‘YES’ votes and funded one by one until the category budget runs out. Any leftover funds excludes proposals submitted in ‘Cardano Use Cases: Product’ and ‘Catalyst Systems Improvements’ categories.

Includes Fund 10 and 11 total funds, converted to USD at the time of fund launch. Please note, any ecosystem role incentives are not included in these figures.

Funds requested by funded projects. Please note, any ecosystem role incentives are not included in these figures.

There's some funds left in each category that haven't been given out. All that leftover funding is put together into a new category called 'Sponsored by Leftovers'. All approved (and not yet funded) proposals across the entire Fund are eligible for this funding, except proposals from the 'Cardano Use Cases: Product' or 'Catalyst Systems Improvements' categories.

Title of the proposal is a link that will bring you to the proposal detail page.

The number of Cardano wallets that take an active part in the Catalyst voting event. Each wallet can vote once per proposal. The number indicated by each proposal represents a number of unique wallets casting a vote for that specific proposal.

Total voting power in ada casting an ‘ABSTAIN’ vote from all wallets combined. ‘ABSTAIN’ votes can be found in the results CSV for reference and do not count towards the approval criteria thresholds.

Total voting power applied in opposition of a proposal

Total voting power in ada casting a ‘YES’ vote applied in support/favor of a proposal from all wallets combined counting towards approval criteria thresholds.

Amount of ada registered to vote in Catalyst determined by the voting power snapshot unique for every funding round. For Fund11, the snapshot took place on Jan 15, 21:45 UTC. Each wallet has its own unique voting power based on the balance on the day/time of the snapshot. Each time a wallet casts a vote, it uses its full voting power applied to a proposal. This can be done only once per each proposal: ‘YES’ or ‘ABSTAIN’.

Project Catalyst explained: an innovation engine from IOG

Project Catalyst is the world’s largest decentralized innovation engine for solving real-world challenges.

Ideas. Innovation. Impact.

Project Catalyst has funding rounds every few months, with a set amount of ada ready to allocate to ideas.

At the start of each Fund, the community has three weeks to submit proposals to answer challenges set in the previous funding round. Proposals are selected by community vote and funding is allocated to bring the projects to life.
