Welcome aboard the Sl8 Social Crypto Platform! 🚀🚀

Stellar is an open-source blockchain that enables global economic transactions. With the help of a $100 million adoption fund provided by the Stellar Development Foundation, this blockchain has made Soroban available in advance to make it easier to create and use Stellar smart contracts (SSC).

This article will help you understand this Stellar blockchain development for smart contracts, its use cases, and more.

What is Stellar Blockchain?

Stellar is an open-source and decentralized global trading network that enables inexpensive transfers between digital currency and fiat money. Also, it allows cross-border currency exchanges between any two currencies. It uses blockchain technology, just like other cryptocurrencies, to maintain network synchronization.

Stellar is speedier, less costly, and more effective than existing blockchain-based financial access and inclusion systems. Stellar Lumens (XLM) is its native coin, facilitating international transactions.

One of Stellar’s key features is its focus on financial inclusion. Thus, Stellar aims to make financial transactions more efficient, affordable, and accessible to people worldwide, particularly those currently underserved by traditional banking systems.

It offers an efficient system for fast and low-cost digital asset issuance and transfer.

Stellar Smart Contracts (SSC)

Smart contracts define and secure connections via computer networks by integrating user interfaces and protocols. The goals and guiding principles of smart contract development come from concepts of secure protocols, economic theory, and legal principles.

Smart contracts are expressed as Stellar smart contracts (SSCs) on the Stellar network. Connected transactions inside an SSC operate under various limitations.

When developing SSCs, the following constraints can be taken into account and implemented:

Multisignature

Multisignature refers to a concept in which different people must sign transactions from an account. People can also assign thresholds and signature weights.

Atomicity/Batching

Several operations are combined into a single transaction under the batching principle. If one operation in a transaction fails, atomicity causes the transaction as a whole to fail.

Sequence

On the Stellar network, sequences are denoted by sequence numbers. These sequence numbers are used by the blockchain to control transactions and make sure they fail if a substitute is available.

Time Bounds

Time bounds set limits on how long a transaction can be valid. They express periods in an SSC.

Soroban — a Smart Contract Platform

Soroban is a smart contract platform for the Stellar network. Based on WASM (web assembly) and Rust, the Stellar network supports Soroban’s Turing-complete smart contracts. When combined with the strength of the Stellar network, Soroban on Stellar will enable use cases focused on extending access to financial services.

Founders created this new type of smart contract platform for the built-to function. A preview of Soroban is live on Futurenet. Now, developers can start building and deploying smart contracts on a test system with Soroban and earn rewards for their work.

Founders built Soroban for scalability, a battery-included developer experience, and reliable access to financial channels via the Stellar network.

Soroban Design Principles

Founders developed Soroban to perform through the following three design principles:

Battery-included

The intention behind creating Soroban is to provide developers with a battery-included experience. Developers have direct access to the resources they need to start quickly and deploy solutions successfully.

Soroban developers will have access to a Local sandbox for quick setup and iterative development. As a result, they can run and debug their contracts independently, locally, and without the assistance of the Stellar network.

A comprehensive and effective set of host functions and built-in contracts are also available to save time. One such function is a built-in efficient token contract that eliminates the need to copy and paste ERC-20 contracts.

Scalability

Another principle of Soroban is scalability. The platform offers a base that can support concurrency immediately. Soroban transactions comprise footprints as transaction dependencies. They use contemporary multi-core hardware to run group transactions simultaneously.

Soroban has a limited number of deserialization and serialization loops. The smart contract development process is easy as the platform does not have encoding and decoding, which consumes significant time and computer resources.

Access to Financial Rail

Soroban creates trusted connectivity to financial networks via the Stellar network. Creators integrated Soroban into the current Stellar ecosystem and tech stack, allowing developers to take full advantage of Stellar’s strengths as a tested, reliable network.

Stellar Smart Contract Use Cases

The following are the SSC use cases:

Digital Identity and NFTs

Developers can use Stellar smart contracts for non-fungible tokens (NFTs). People can convert their gaming assets, certifications, credentials, and more into digital assets on the Stellar blockchain. The blockchain stores the metadata of these assets. Stellar smart contract code configures the metadata to determine ownership and reassign the same with the NFT.

Decentralized Finance (DeFi)

Stellar smart contracts (SSCs) enable the functioning of decentralized finance (DeFi) solutions, including borrowing, lending, tokenization, payment apps, and more. DeFi businesses utilize them to protect the atomic escrow account. Here, SSCs’ regulations control the assets. Programs will only release these assets after the fulfillment of certain conditions.

Stellar Smart Contract Development

With the increase in people migrating to different countries, the number of cross-border payments has increased. According to the World Bank, about $630 billion was sent in remittances to low- and middle-income nations in 2022. It is expected that the value of cross-border payments to reach over $250 trillion by 2027. However, hefty fees, averaging 7–8% (and up to 15% for developing economies), and prolonged processing times persist through various intermediaries. Here, Stellar blockchain can be used as a solution with its high-speed and low-cost transactions. In this article, we explore how Stellar blockchain development services can solve various challenges in cross-border payments.

Challenges with Traditional Cross-Border Transactions

Most international money transfers pass through the SWIFT (Society for Worldwide Interbank Financial Telecommunication) system. Instead of sending actual money from the paying bank to the receiving bank, SWIFT transfers specific instructions, ensuring the security of financial transactions between its members.

Even after five decades in operation, SWIFT remains slow and costly. International money transfers heavily rely on SWIFT as an intermediary, incurring fees that elevate transaction costs. Consequently, it may take 3–5 business days for funds to reach the recipient.

The goal of the Stellar blockchain is to provide a quicker substitute that avoids these costs and delays.

Understanding Stellar for Cross-Border Payments

Stellar is an open-source blockchain that enables international payments. Its native digital currency is Lumen (XLM), which enables users to set up their account and transaction processing within the Stellar network. Stellar was developed with the intention of reducing obstacles to cross-border payments, advancing financial inclusion, and setting a new global payment standard.

Built-In Features of Stellar

Let us understand the built-in features of Stellar:

Speed: Stellar ensures swift confirmation of transactions, typically within five seconds, offering an efficient environment for financial operations

Cost: Stellar performs transactions with negligible transaction fees, averaging just over .000002 XLM per transaction.

Scalability: The network is capable of processing up to 1000 transactions per second (t/s), rivaling the volume managed by SWIFT. Since its inception in 2015, the network has impressively handled over 13 billion operations.

How Stellar Simplify Global Payments Without Intermediaries

Stellar establishes a seamless, blockchain-powered payment infrastructure and collaborates with local partners known as anchors. On the Stellar network, these anchors act as ports of entrance and departure for different international currencies.

Much like SWIFT, Stellar employs a standardized protocol. The network ensures consistent communication among all participants. Companies that use Stellar can send fiat money to an anchor, which enables a quick conversion to the recipient’s local currency. The receiver receives this converted value with ease thanks to a local anchor in their area.

This entire process eliminates the necessity for intermediary banks. Both the service provider and the buyer can conduct transactions in their respective local currencies. In essence, Stellar unifies the many procedures involved in foreign wire transfers and currency conversion into a single, straightforward channel.

What Does Stellar Offer in Cross-border Payments

Here are the use cases of Stellar in the payment sector:

Remittances

Stellar facilitates seamless transactions between individuals. It ensures swift coverage of everyday expenses.

Global Payroll

Stellar’s platform allows for payroll distribution in local currencies without imposing minimum transaction requirements. It enables businesses to pay employees globally more efficiently.

Treasury Management

Stellar manages liquidity in operating accounts without pre-funding them. It provides better financial agility and effective treasury management for organizations using Stellar’s network.

Business Invoicing

Employing Stellar, enterprises can issue invoices to suppliers and other businesses without the need for pre-funding accounts. This simplifies and expedites the invoicing process.

Merchant Settlement

It expedites payouts and effortlessly converts funds back to a single operating currency for seamless merchant settlements.

Social Payouts

Stellar facilitates the issuance of partial or full payments for grants, aid, and government services. It ensures a streamlined process for social payouts.

Enterprise Payouts

Stellar improves the efficiency of enterprise-level payments. With Stellar, businesses can easily reconcile corporate payouts without the need for pre-funding accounts.

Conclusion

The financial ecosystem must adopt Stellar-based blockchain solutions to revolutionize cross-border payments. Embracing this approach will enhance security, minimize risks, and elevate international transactions to new heights with secure, real-time, and cost-effective transfers.

Introduction

The Stellar Consensus Protocol (SCP) is a consensus algorithm developed by the Stellar Development Foundation (SDF) for the Stellar network. It serves as the underlying mechanism that enables decentralized agreement and consensus among nodes in the network. SCP ensures that all participants in the network have a shared view of the system state and agree on which transactions are valid and should be included in the blockchain.

Consensus protocols are fundamental to the functioning of blockchain networks, as they allow distributed systems to operate in a trustless environment without relying on a central authority. SCP addresses the challenges of achieving consensus in a decentralized and Byzantine fault-tolerant network, where nodes can be unreliable, malicious, or face network partitions.

Unlike traditional consensus algorithms such as proof-of-work (PoW) or proof-of-stake (PoS), SCP employs a federated Byzantine agreement protocol. This means that instead of relying on computational power or stake ownership, SCP relies on a decentralized network of trusted nodes to reach consensus.

SCP operates through a series of iterative rounds, wherein nodes are selected to form quorum slices. These quorum slices are subsets of nodes that are considered trustworthy and provide accurate information. The protocol progresses through proposal, preparing, prevoting, precommitting, and committing phases, allowing nodes to agree on the state of the ledger and the validity of transactions.

One of the key advantages of SCP is its scalability and energy efficiency. By avoiding resource-intensive processes like mining in PoW algorithms or the concentration of power in PoS algorithms, SCP enables fast, secure, and low-cost transactions on the Stellar network.

The Stellar Consensus Protocol plays a crucial role in maintaining the integrity and security of the Stellar blockchain. It ensures that all nodes in the network can participate in consensus and collectively validate transactions. Through SCP, the Stellar network achieves decentralization, fault tolerance, and resistance to censorship, making it a robust platform for various financial applications, including cross-border payments, token issuance, and decentralized exchanges.

The Stellar Consensus Protocol (SCP) is a consensus algorithm developed by the Stellar Development Foundation (SDF) for the Stellar network. It is designed to facilitate decentralized consensus among nodes in a distributed network and is a key component of the Stellar blockchain.

The primary goal of the Stellar Consensus Protocol is to ensure agreement and consistency across all nodes in the network, even in the presence of malicious actors or network partitions. It achieves this by allowing participating nodes to reach a global agreement on the state of the network through a series of iterative rounds.

Here's a simplified overview of how the Stellar Consensus Protocol works:

Node selection: Each round begins with a set of nodes called "quorum slices" being chosen from the network. These quorum slices are subsets of nodes that are trusted to provide accurate information.

Proposal phase: In this phase, a node proposes a value or a set of transactions to be included in the next ledger. The proposal is then broadcasted to the network.

Preparing phase: Nodes receive the proposal and independently verify its validity. If they agree, they prepare the proposal by creating a "prepare" message and broadcasting it to the network. The prepare message contains a hash of the proposal and serves as evidence of agreement.

Prevote phase: Nodes collect prepare messages from other nodes and use them to create a "prevote" message. This message includes the hash of the prepare message the node voted for. Nodes broadcast their prevote messages to the network.

Pre Commit phase: Once a node receives a sufficient number of prevote messages that are consistent with each other, it enters the precommit phase. In this phase, the node creates a "precommit" message that includes the hash of the prevote it voted for. The precommit message is then broadcasted to the network.

Commit phase: Nodes collect precommit messages from other nodes and use them to create a "commit" message. This message serves as proof that a node has seen enough consistent votes to reach a global agreement. Once a node receives enough commit messages, it commits the proposed value or transactions to its local ledger.

By following these steps, the Stellar Consensus Protocol allows the network to agree on the state of the ledger and reach consensus on which transactions are valid and should be included. This consensus process ensures the integrity and security of the Stellar blockchain.

It's important to note that the Stellar Consensus Protocol is different from traditional proof-of-work (PoW) or proof-of-stake (PoS) consensus algorithms. SCP relies on a federated Byzantine agreement protocol, where nodes are chosen based on trust rather than mining power or stake ownership. This makes SCP more energy-efficient and scalable compared to PoW-based protocols.

Overall, the Stellar Consensus Protocol plays a crucial role in maintaining the decentralized nature of the Stellar network and enabling fast, secure, and low-cost transactions.

use of stellar consensus protocol

The Stellar Consensus Protocol (SCP) is primarily used within the Stellar network for achieving consensus among nodes and maintaining the integrity of the blockchain. It serves several important purposes and enables various use cases within the Stellar ecosystem. Here are some key applications of the Stellar Consensus Protocol:

Transaction Validation: SCP ensures that all participating nodes agree on the validity of transactions within the Stellar network. This allows for secure and reliable transaction processing, preventing double-spending and other fraudulent activities. By achieving consensus on transaction validity, SCP enables trustless and decentralized financial transactions.

Decentralized Exchange (DEX): SCP facilitates the operation of decentralized exchanges on the Stellar network. With SCP, the network can agree on the order and execution of trades, ensuring fair and transparent exchange of assets. This allows users to trade tokens directly without the need for intermediaries, providing greater control over their assets and reducing reliance on centralized exchanges.

Cross-Border Payments: Stellar is widely known for its focus on facilitating fast and low-cost cross-border payments. SCP plays a crucial role in this by allowing nodes in the network to agree on the state of the ledger and the validity of payment transactions. With SCP, the Stellar network can settle cross-border payments quickly and securely, making it an efficient solution for remittances and international money transfers.

Asset Issuance: Stellar allows users to issue and trade various digital assets, including tokens and cryptocurrencies. SCP ensures consensus on the creation, distribution, and ownership of these assets. This makes it possible for individuals and organizations to tokenize real-world assets, create new cryptocurrencies, or issue digital representations of traditional financial instruments.

Anchors and Fiat Currencies: Anchors are trusted entities within the Stellar network that act as bridges between the traditional financial system and the blockchain. They issue tokens that represent fiat currencies or other real-world assets. SCP ensures consensus on the operation of these anchors, allowing for the seamless integration of traditional financial assets and cryptocurrencies on the Stellar network.

Consensus for Governance: SCP can also be used for consensus in decentralized governance models within the Stellar ecosystem. It allows network participants to agree on protocol upgrades, changes to network parameters, or the introduction of new features. SCP's consensus mechanism ensures that decisions are made collectively and transparently, promoting a decentralized and inclusive decision-making process.

Stellar Blockchain is an open-source blockchain ecosystem designed to support digital assets and payments. Stellar's native currency is stellar, which pays for the network's computation fees and incentivizes the validators. Leveraging Stellar’s powerful public ecosystem, enterprises can create, mint and trade tokenized versions of real-world money, providing a common unified infrastructure where the global financial system can operate.
