TitleAn alternative to Blockchain using Twitter
Project id.36
Reference sectorICT
IP Protection LevelNo patent as yet
Description of the innovation projectDespite the rapid growth of interest of both researchers and companies in Blockchain for all possible applications, it is well-known that the protocol (even in the 2.0 version) has some weaknesses. We propose an alternate public ledger that, instead of the P2P network and the protocol of Blockchain, leverages the popular social network Twitter, by building a meshed chain of tweets to ensure transaction security. Importantly, Twitter does not play neither the role of trusted third party nor the role of ledger provider. From a conceptual point of view, the protocol is fully decentralized as in Blockchain, but the weaknesses above mentioned are overcome.

Advantage factorAt the moment, what is limiting the diffusion of blockchain-based applications is (1) the computational cost of the PoW, (2) the fact that users have to enter in a P2P network, (3) the pseuso-anonimity of transactions/smart contracts (in many case we have to trust and authorize the involved actors). Our Twitter-based solution overcame all the above drawbacks.
