  There are thousands of projects worldwide based primarily on blockchain
technology. These have a large number of users and hundreds of use cases. One
of the most popular is the use of cryptocurrencies and their benefits against
money without intrinsic value (fiat money) and centralized financial solutions.
However, although thousands of new transactions are carried out daily in
different platforms, uniform and standardized information does not exist to be
able to manage the large amount of data that is generated and exchanged between
users through transactions and the generation of new blocks. This research
reports the development of BLONDiE, an ontology that allows the semantic
representation of knowledge to describe the native structure and related
information of the three most relevant blockchain projects to date: Bitcoin,
Ethereum and in the recent 1.0 version extends its definitions to include
Hyperledger, specifically the Hyperledger Fabric infrastructure. Its use allows
having common data formats of different platforms for further processing, such
as the execution of semantic queries.
