Solution: A bounty management system that integrates Github PRs with Marlowe contracts, minimizing the trust requirements between parties and removing the need for intermediates.

Solution: A bot challenge, incentivized by ADA rewards, that showcases the capabilities of the UTxO model by participating in a compelling on-chain strategy challenge.

Solution: A framework for building self-contained, portable logic for reading and participating in on-chain smart contract protocols.

Solution: A streaming, real-time API that uses gRPC + protobuf to provide a performant and developer friendly way to interact with the Cardano blockchain.

Solution: A reference implementation of a Substrate node that uses an UTxO-based ledger and a Plutus VM, allowing the execution of Cardano-like dApps in Substrate-based networks.

Solution: We will build a generic backend component that serves as a smart, massive mempool. It can be used by dApps directly out-of-the-box as a resilient and performant mechanism for tx submission.

Solution: We'll contribute a new Rust library that implements a peer-to-peer networking compatible with Cardano to be used by Amaru and any other Rust-based application that requires it.

Solution: We'll build a reference implementation of a Substrate partnerchain that can be use by developers in the ecosystem as blueprint / example to build their own specific chains.

Solution: Oura is a battle-tested Cardano-specific tool to observe and process on-chain events. We'll extend Oura's capabilities to support observing events from Bitcoin, Ethereum and Substrate.

Solution: A light, self-custodial, open-source wallet that runs on the terminal, enabling new capabilities for power-users around automation and programability which can't be find in other wallets.

Solution: We'll build a SuperNode, a new infrastructure tool aimed at SPOs, capable of onboarding and operating multiple Cardano partnerchain nodes using a unified and simple interface.
