Bernardo Ferreira and Bruno Cotrim, LASIGE researchers, integrated member and master’s student, respectively, received an honorable mention in the Arquivo.pt 2025 Awards, given by the DNS.PT Association, released on 28 June 2025.

‘ArchiveChain’ was developed as part of the Master’s thesis in Computer Engineering and it is a blockchain that democratizes the mission of archiving the Portuguese historical web. In ArchiveChain, all citizens are invited to save pages from Arquivo.pt, and whoever saves the most pages receives the most rewards in the form of cryptocurrencies. At the same time, the pages saved by participants are used as ‘fuel’ in its internal workings, making it possible to implement smart contracts in a sustainable way and avoiding the massive energy consumption of other blockchains such as Bitcoin.

Ferreira expressed that “we have created a more sustainable blockchain that consumes storage capacity with Arquivo.pt pages”.

LASIGE congratulates the recipients of the honorable mention, both for their scientific work and for their contribution to sustainability.

We invite you to start exploring the ArchiveChain platform and generating to the better preservation of the Portuguese web!
