During execution of the protocol, the nodes reach consensus and converge on a common output by exchanging messages.

Going far beyond its use in cryptocurrencies, blockchain is regarded today as a promising technology to simplify trusted exchanges of data and goods among companies. Starting with the celebrated protocols for Byzantine Agreement established in 1982, consensus protocols have found widespread applications for keeping distributed systems healty and making cloud platforms operate continuously.

Il a déjà été signalé que cette technologie est un moteur important des revenus de l’entreprise dans les services de Cloud : « Lorsque l’on examine l’attribution directe des dollars réellement dépensés pour la Blockchain, on constate que pour chaque dollar dépensé, 15 dollars sont consacrés à d’autres services de cloud computing ». It is a global collaboration including leaders in finance, banking, IoT, supply chain, manufacturing and technology. All nodes validate the information to be appended to the blockchain, and a consensus protocol ensures that the nodes agree on a unique order in which entries are appended.

[3] E. Androulaki, C. Cachin, A. [8] M. Vukolic, Today, consensus protocols exist in many variations, but all of them need a majority or even a qualified majority (such as 2/3 of the nodes) to be correct, whereas the remaining ones could fail, misbehave, or even act adversarially against finding consensus.
IBM collabore également avec Connecting Food, une "foodtech" qui utilise la blockchain pour tracer et certifier les produits alimentaires. Transactions are executed “on” the blockchain with the help of consensus protocols and may append new records to the ledger.
