Open source C++ implementation of the Ethereum Execution Layer (EL) protocol.

Silkworm is a greenfield C++ implementation of the Ethereum Execution Layer (EL) protocol based on the Erigon Thorax architecture. It aims to be the fastest Ethereum EL client while maintaining the high quality and readability of its source code.

I contributed to the project by developing the C++ version of the header and body downloader for Proof of Work (PoW), adapting the innovative approach originally devised in Erigon.

Furthermore, I played a supportive role in the integration of Proof of Stake (PoS), specifically by implementing an inversion of control strategy as envisioned by our lead developer. This pivotal modification transformed the operational dynamic, enabling the Consensus Layer (CL) to direct the EL. This shift away from an EL-centric loop involving the CL to a more flexible architecture made it possible to plug different CL algorithms into the system, significantly enhancing its adaptability and performance.

A capital markets protocol for borrowing and lending built on the top of the Algorand blockchain.

Folks Finance is a DeFi (Decentralized Finance) project developed by Blockchain Italia. I was instrumental in laying the foundation for this project and have been part of the team since its inception.

My role involved drafting the initial design of the protocol on the Algorand blockchain, at a time when there were no DeFi projects on Algorand and skepticism existed regarding the feasibility of such implementations.

My contributions also included the development of the core mathematical models and their practical implementation, thereby establishing the groundwork for what would become a pioneering DeFi service on the Algorand platform.

A serverless application that uses AWS Step Functions workflow to model an Ethereum transaction life cycle. It signs & submits a tx, tracks its outcome, speeds up or recovers it if lost.

The application enables an enterprise component to interact with an Ethereum-like blockchain using an HTTP REST interface hiding the underlying details.

The project uses the serverless framework (see here) so that the owner only pays when he/she uses it; it generates an AWS Api Gateway backed by lambda functions and uses MongoDB for persistence.

Thanks to its object-oriented model, the code is short and the lambda functions are clean (they only manage HTTP issues); persistence is schemaless to truly take advantage of the NoSQL paradigm. I used ethers.js for blockchain related stuff.

A decentralized application for document certification, contract acceptance and property transfer that issues ERC-721 tokens.

I was a member of the team that developed this application. We used the Universal Login framework for frictionless user experience with Ethereum-like blockchain, IPFS as document repository, an Ethereum sidechain as default blockchain, a transaction relay infrastructure to pay gas using tokens, the Arbitrary Message Bridge to transfer relevant tokens to the Ethereum mainnet and vice versa, react.js for the user interface and no servers!
