PhD candidates Yonatan Sompolinsky and Dr. Aviv Zohar, both from the Hebrew University of Jerusalem, this week published a document on a new scalable BlockDAG, an alternative network structure to the Blockchain protocol, called PHANTOM. https://i1.wp.com/criptotendencia.com/wp-content/uploads/2018/02/Scalable-Blockchain-Alternative-Mineria-Criptomonedas.jpg?w=725&ssl=1 [Fuente](https://i1.wp.com/criptotendencia.com/wp-content/uploads/2018/02/Scalable-Blockchain-Alternative-Mineria-Criptomonedas.jpg?w=725&ssl=1) Sompolinsky and Zohar's 2013 document on the GHOST protocol introduced the BlockDAG structure, which essentially transforms Bitcoin's Blockchain structure into a tree, as a way to improve security and speed up transaction times. In a talk at "Blockchain in Berkeley" in November 2017, Sompolinsky explained that the BlockDAG structure serves everyone simultaneously. This is in contrast to the Blockchain structure, in which new blocks are added one by one once they have been verified. The PHANTOM document is based on the researchers' SPECTRA protocol, which confirms transactions with recursive voting from previous blocks. However, unlike SPECTRA, PHANTOM will use a "greedy algorithm" in a BlockDAG protocol to create a more linear block structure by "distinguishing" between blocks correctly mined by honest nodes and those extracted by non-cooperating nodes that deviated of the DAG mining protocol ". The PHANTOM linear structure means sacrificing the fastest confirmation times that come with SPECTRA, although the document raises the possibility of combining the two protocols to "enjoy the best of both worlds". Although most cryptocurrencies are executed in a Blockchain protocol, there are several that run in BlockDAG. Byteball is a DAG-based currency in which transactions are linked to each other and contain hashes of previous transactions. IOTA is also based on DAG: the creation of a new transaction must validate at least two previous transactions.
