Stellar and IBM had partnered to form the IBM World Wire. The SCP whitepaper, titled "The Stellar Consensus Protocol: A Federated Model for Internet-Level Consensus," is available online on the Stellar website.The whitepaper is a technical paper not easy to understand for casual readers, and therefore Stellar has provided a readable . Stellar Consensus Protocol: An Overview In a 2015 whitepaper, David Mazières described the Stellar Consensus Protocol (SCP). It is based on Federated Byzantine Agreement system, but instead of a predetermined set of trusted nodes, every node is able to pick the nodes they trust to validate transactions. Stellar is an open-source protocol for exchanging money or tokens using the Stellar Consensus Protocol. It is made possible by addressing the shortcomings of Bitcoin protocol. Anchors act as a bridge between the traditional finance world and the Stellar network. Much like Paxos, the protocol can be considered in a single instance (i.e., Stellar Consensus Protocol Stellar's biggest update occurred in 2015 when it replaced the mechanism it used to keep the computers running its software in agreement about the state of its ledger with a custom-built alternative. Different from BFT, Stellar's consensus mechanism is a type of Federated Byzantine Agreement (FBA) referred to as the Stellar Consensus Protocol (SCP). Stellar Consensus Protocol is the first implementation of a type of consensus protocol called Federated Byzantine Agreement (FBA). Close. The SCP was first introduced and architected in 2015 by David Mazières, a Harvard educated and MIT alumnus as well as a professor of Computer Science at Stanford University. The upshot: counterparties can transact trustlessly, at very low costs. Stellar Consensus Protocol is the basis of public infrastructure for money, making Stellar a blank canvas for people to design financial services that fit . Previous FBA protocols had a determined membership list. The underlying consensus algorithm of the Stellar network is the Stellar Consensus Protocol (SCP). However, Stellar has since made technical changes that differentiate its offering. Ecosystem momentum. Servers run a software implementation of the protocol, and use the Internet to connect to and communicate with other Stellar servers. Could consensus period be changed? In other words, Stellar aims to provide a platform with which all financial actors can interact without any friction. FBA was idealized in 2015 by Professor David Mazières of Stanford..
