Understanding the Stellar Consensus Protocol by Bob Glickstein Interstellar

Stellar burned almost half of its outstanding lumens in 2019, which led to a rise in price. Since manipulating cryptos may be hazardous, this has raised considerable debate. To try to stabilize its market, Stellar announced that it would stop producing any more lumens, after which the price quickly stabilized.

An important innovation of SCP is that it removes the responsibility for making quorums from the consensus algorithm itself and pushes it into the application layer. This suggests that, although federated voting is general enough to work with any kind of value being voted on, in fact its robustness depends critically on the broader meaning of those values. Some hypothetical uses might not lend themselves as readily to producing well-connected networks as others.

A blocking set is just one node chosen from each of N’s quorum slices. If all nodes in such a set accept W, then (by Theorem 8) it will never be possible to form a quorum accepting not-W, and so it’s safe for N to accept W too. All the participants, or nodes, must agree on some decision, such as whose turn it is to update a shared file or pull a task from a processing queue.

Goes through the meaning of decentralized network, ledger, consensus, anchors, distributed exchange, and multi-currency transactions. The Stellar Consensus Protocol uses federated voting in a way that guarantees safety and liveness.⁴ The idea, in a nutshell, is to conduct multiple federated votes on multiple values until one makes it all the way through SCP’s various voting phases, described below. The federated voting procedure just described is safe in the sense that if a node confirms value V, no other node will confirm a different value. But “won’t confirm different things” is not the same as “will confirm something.” There may be so many different values being voted on that nothing even reaches the “accept” threshold.

So in addition to casting their own nomination votes, nodes “echo” the nominations of their peers. In practice SCP protocol messages batch these separate votes together. After finding confirmable nominees, SCP moves to the balloting phase, where the goal is to find some ballot (which yinbi crypto is a container for a nominated value) and a quorum that can commit to it. If a quorum commits to this ballot, its value is the outcome of this round of consensus. But before a node can vote to commit to a ballot, it must first confirm that all lesser ballots are aborted.

  • Other Byzantine agreement systems owe much of their complexity to making guarantees about quorums.
  • The main competitors of Stellar (XLM) are Ripple (XRP) and Bitcoin (BTC).
  • “This paper introduces a new model for consensus called federated Byzantine agreement (FBA).
  • The initial total supply of XLM was 10 billion tokens, with a built-in mechanism for a 1% inflation.

Think of Stellar Core as the software used to make verification possible. Stellar is an open-source protocol for exchanging money or tokens using the Stellar Consensus Protocol.[1] The platform’s source code is hosted on GitHub. The Internet is the perfect example of a network of independent nodes with quorum intersection. Most nodes on the Internet connect to just a few other local nodes, but those small sets overlap enough that every node is reachable from every other node by one route or another. It might seem unreasonable to expect a collection of independent nodes to organize their slices in such a way that the network will reliably enjoy quorum intersection.

It’s very different from Bitcoin, which uses proof of work (page 3) to verify transactions. Nomination is only about producing — and limiting the number of — candidates for consensus.

Unlike prior Byzantine agreement models, which presuppose a unanimously accepted membership list, SCP enjoys open membership that promotes organic network growth. Compared to decentralized proof of-work and proof-of-stake schemes, SCP has modest computing and financial requirements, lowering the barrier to entry and potentially opening up financial systems to new participants. Rather than use a standalone cryptocurrency to transfer value over international borders, Stellar would have users transmit fiat-equivalent credit over the stellar blockchain. This credit is issued by “anchors,” or financial institutions that function as “bridges” between fiat currencies and the stellar network.

The benefits offered by Stellar — such as token issuance and upcoming Lighting Network implementation — place it in a strong position to continue to grow and potentially dethrone Ripple as the token of choice for legacy financial infrastructure. XLM is primarily traded on Binance, where the XLM/BTC trading pair accounts for over 26% of all trading volume. A further 20% of current XLM volume is traded on Upbit via the XLM/KRW pair. Poloniex, Bittrex, and Binance are other popular markets for Stellar Lumens. Ripple operates a permissioned ledger that restricts who can function as a transaction validator — Stellar, however, allows anybody to validate transactions. Ripple’s consensus mechanism is also vastly different from the manner in which Stellar gains consensus.

  • Transaction recipients are able to withdraw credit via an anchor service.
  • In a round of federated voting, each node must choose one of potentially many possible values as the outcome of that round.
  • This suggests that, although federated voting is general enough to work with any kind of value being voted on, in fact its robustness depends critically on the broader meaning of those values.
  • These anchors can be payment processors or centralized banks, and function as bridges between fiat currency and cryptocurrency.

The Fed stated that its approval hinges on the ability of banks to show that they possess the necessary control systems to manage the risks tied to stablecoins. The network launched in 2014 as a fork of the Ripple project backed by a $3,000,000 loan from Stripe, which was subsequently repaid with 2% of the initial 100 billion Stellar Lumen release. Stellar will automatically find the best prices to exchange currencies for the user.

SCP explains how a node should handle each type of peer message no matter what phase it’s in. The process of voting, accepting, and confirming makes up one complete round of federated voting. The Stellar Consensus Protocol combines many such rounds to create a complete consensus system.

Although they coexist in the same system, Stellar and XLM are two distinct entities. Lumens are traded on the blockchain network, which is built on the Stellar platform. An important keyword from this system is it uses leaderless computing network decision making to validate system/nodes outcome of transaction payment systems.
