Because it is decentralized and with an open implementation, there are several online currencies that follow the same structure. Analysing Bitcoin definition one realises of the possibility of colouring them. There exist many methods of implementing such colouring but, after several months of discussion, the community decided to implement what is known as Ordering Bitcoin Colouring (OBC). Colouring systems require for the creation of what is known as colour definition. These are files which describe the name of the colour, the means of identifying it; they can include several signatures and certifications. With the existence of such colours, appears the need for exchanging the definitions and trading the coloured coins. Currently, the only way of doing so is by means of a central server. Such centrality does not belong to what is desired in decentralized networks. This is why it is appealing to build a system that can circumvent the central server. This project provides a definition of the structure of such system, as well as a working prototype as a proof of concept.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaIntercambio electrónico de datosSoftware libreTecnología P2PDesarrollo de softwarebachelor thesisInformáticaopen access
