Rafael Cosman

Rafael Cosman is recognised as a co-founder of TrustToken, a blockchain technology company that later rebranded to Archblock. The company emerged during the early growth phase of decentralised finance, focusing on solving practical challenges in bringing real-world assets onto blockchain networks. Cosman's involvement in the founding positioned him as a key figure in the development of asset tokenisation solutions.

His work has centred on the technical and conceptual architecture required to bridge traditional finance and decentralised blockchain systems. Through his role at TrustToken/Archblock, Cosman has contributed to the broader discussion around how blockchain technology can facilitate the tokenisation of assets including commodities, securities, and other real-world instruments.

TrustToken was established to address a specific problem in early cryptocurrency and blockchain adoption: the need for stable, reliable representations of real-world value on decentralised networks. The platform developed infrastructure to tokenise various asset classes, creating blockchain-based tokens backed by real-world collateral. This approach distinguished TrustToken from purely speculative cryptocurrency projects and positioned it within the growing infrastructure layer of decentralised finance.

The company's work included creating stablecoin mechanisms and systems for transparent asset-backed tokenisation. Cosman's contributions to the technical strategy of these systems reflected broader industry efforts to create bridges between traditional finance and blockchain-based systems. The development of trustworthy, auditable asset tokenisation mechanisms became increasingly relevant as institutional interest in blockchain technology grew.

TrustToken's later rebranding to Archblock reflected an evolution in the company's strategic focus and market positioning. As a board member of Archblock, Cosman has continued to shape the organisation's direction in the competitive landscape of decentralised finance and blockchain infrastructure development.

Cosman's work exemplifies the shift towards practical applications of blockchain technology beyond cryptocurrency speculation. By focusing on asset tokenisation, he has contributed to narratives around blockchain's potential to improve efficiency, transparency, and access in traditional finance. The tokenisation of real-world assets remains an area of significant development and experimentation across the cryptocurrency and decentralised finance sectors.

As part of the Archblock leadership, Cosman continues to operate in a sector that bridges finance, technology, and regulation. The challenge of creating scalable, compliant systems for asset tokenisation requires both technical innovation and engagement with regulatory frameworks. His ongoing work reflects the maturation of blockchain technology from a purely speculative asset class towards infrastructure with potential applications in settled financial markets.
