It implements the Stellar Consensus Protocol, a federated consensus protocol. Often a super-majority is deemed sufficient. Answer: Transactions are fast, inexpensive, and global. For context, XLM does not rely on Proof-of-Stake (PoS) or Proof-of-Work (PoW) but instead uses an FBA-based algorithm known as the Stellar Consensus Protocol (SCP). Ripple VS Stellar both want to disrupt the global financial payment systems even though they are using two completely different approaches. Consensus already at work Consensus-based transaction mechanisms have been on the market for some time. A consensus mechanism is a fault-tolerant mechanism that is used in computer and blockchain systems to achieve the necessary agreement on a single data value or a single state of the network among . The Stellar Consensus Protocol (SCP) provides a way to reach consensus without relying on a closed system to accurately record financial transactions. Q4: Why would banks and businesses use Stellar? Ethereum, like Bitcoin, currently uses a consensus protocol called Proof-of-work (PoW). 95% of all the stellars are set to be distributed to as many people worldwide as possible through a series of giveaways specified in their mandate. This protocol is still evolving, as is our knowledge of its limits and possible failure cases. Proof of work is a requirement to define an expensive computer calculation, also called mining, that needs to be performed in order to create a new group of trustless transactions (the so-called block) on a distributed ledger called blockchain. Consensus Protocol. Consensus protocols are a solution to the double-spend problem: the challenge of preventing someone from successfully spending the same digital money twice. 1.
