OLEA is a project that mixes biotechnology, history, conceptual and visual art and cryptography.   In collaboration with the CSIC and specifically the Instituto de la Grasa de Sevilla in Spain, the bioinformatician Javier Forment and the support of the Escuela Superior de Arte y Tecnología from Valencia, Spain, where Solimán has his R+D+I laboratory, the artist has managed to produce a unique olive oil. The particularity of this olive oil is that its composition contains DNA molecules with the synthesis of the code of a smart contract in the blockchain, which gives life to what the artist calls a “biotoken”.   With this biotechnology action, the artist has managed to unite two of humanity’s historical economies in a single liquid. On the one hand, the oldest and most physical, agriculture, and on the other, the newest and most intangible, blockchain and digital. The project also aims to revalue the product of the earth, to reflect on the origins of the value of things and is also a personal tribute to the artist’s family past.
