How to Build & Deploy Smart Contracts on Solana?

What exactly is Solana?

Solana is an uncentralized blockchain system that is designed to alleviate the problems of congestion and scalability present in the current blockchains. Its primary goal of enhancing scalability, like a higher number of transactions per second (TPS) and faster confirmation times. It’s an open-source project that consists of the most innovative technologies of Intel, Netscape, Google, Qualcomm to support Solana in ensuring high-performance standards. For a thorough analysis of Solana take a look at our research completely dedicated to Solana.

What is the Architecture of Solana Smart Contract?

Solana’s smart-contract model is different from the traditional EVM-enabled blockchains. Traditional EVM-based contracts combine state and code in one contract that is implemented on the chain. However the smart contract that runs that runs on Solana is in read-only or stateless mode, and contains code only. When the smart contract is installed, it is accessible by other accounts and these accounts can interact with the software to store information related to program interactions.

This is how the separation of states (accounts) as well as contractual logic (programs) occurs this is a key distinction between traditional EVM-enabled as well as Solana smart contracts. Furthermore accounts on Solana as well as different Blockchains (like Ethereum) are also very different. Accounts on Solana holds information (like account information) unlike Ethereum accounts, which are merely the reference for users wallets.

Metaverse Virtual Reality

The last decade was the internet era. Now the upcoming decades are the metaverse era. The metaverse will allow for more interaction, collaboration, and immersive virtual worlds than the internet. Despite the many startups and technologies that have dabbled in this area, blockchain technology emerged as a technological platform that will support and help build a sustainable ecosystem for metaverse. Gaming NFT markets are an example of a budding metaverse. Leading gaming companies that are eager to start their Blockchain Metaverse projects decentralized are entering the metaverse space confidently, signaling that virtual reality and metaverse is the future.

What is Meta?

Metaverse does not refer to any particular technology. It is a general shift in the way that technology interacts with us. The technologies that make up the metaverse include virtual reality. This is a category that includes obstinate virtual realities that exist even when the user’s not active. It also includes amplified reality which combines the elements of the digital and physical worlds. Virtual reality is interoperable and allows you to move virtual objects such as clothes or cars between platforms. Most platforms have virtual identities and avatars that are tied to a single platform. You might still be able to use your metaverse to allow you to transfer your avatar from one platform into another. Let’s examine the core value the metaverse will look to attribute in order for us to better understand the metaverse.

  • Metaverse will be permanent, meaning it will never reset or pause but will continue on indefinitely.
  • It will be live and synchronous, as the pre-determined events in real life will also take place. However, the Metaverse will be an experience that everyone can enjoy in real-time.
  • Metaverse can be an economy with full functionality where people and businesses can sell, buy, own, invest, and get widely recognized for their work.
  • The metaverse experience can be accessed from both digital and real worlds. It will include private and public networks, open and closed platforms, and digital and physical worlds.
  • Digital assets and digital content can be interoperable in unprecedented ways
  • The metaverse will include content and experiences created by a variety of contributors. These contributors can be independent individuals or informally organized groups.

NFT ticket

As NFTs gain popularity as of late, the NFT market has experienced the level in the range of $24.9 billion, as per information provided by Dapp Radar. While NFTs are transforming the way we do business across many sectors, the event industry is the first to use NFTs to link physically and electronically ticketing. Before the introduction of electronic ticketing, people had to keep old-fashioned tickets. Each ticket had a unique design, bringing back memories, no matter if it was an opera show in Vienna or for the World Cup in England, or an event in California. Digitalization has simplified tickets, the ticketing system has become more efficient and trustworthy for all. However, a simple QR code with no explanation that explains it is dull. Digital tickets can’t be kept as a souvenir that people would like to keep, and to look back at.

Presently, the ticketing system does not allow people to reflect on the special moments of past occasions. Therefore, NFTs are here for making tickets efficient and easier to store to keep as memories.

Tickets made of paper can be lost, damaged by water and damaged. In addition, organizers do not have enough security when using tickets printed on paper. They are also easily counterfeited. QR codes can solve this issue for organizers, however they’re not as effective for the guests purchasing tickets.

What are the issues that the traditional ticketing system faces?

Tickets with black marketing

Fraud has plagued the industry of ticketing and has forced customers to pay more as well as posing security concerns for organizers of events. By utilizing technology in a way that isn’t bots for ticketing, they cause chaos, allowing those who are online to buy tickets in bulk, and then sell tickets to secondary markets for premium prices.

Lack of exchange protocol

It is difficult to trace the customers’ movements or exchange information outside the borders of a provider and the absence of exchange protocols allows fraud on markets that sell on the second. If a ticket is purchased on the secondary market it does not represent any ownership of the buyer who’s information the organizer of the event have. Thus, the event’s organizers don’t know who attends their event. Since tickets are distributed in a way that doesn’t allow exchanges on the secondary market there is no way to change the holders name, nor to determine how often the tickets are exchanged.

Customer Trust

One of the main questions for visitors is whether they bought a legitimate ticket or fake. Sometimes, guests purchase fake tickets from websites that pose as legitimate ticketing agencies which can result in the loss of money and dissatisfaction.

HOW TO CREATE TOKEN ON STELLAR BLOCKCHAIN NETWORK?

The majority of startups launched their tokens on Ethereum because it is an established environment that is also Turing-complete. However, Ethereum does have some drawbacks too. Ethereum is able to process the equivalent of 14 transactions in a second. This is becoming a serious issue and is forcing existing dApps to leave on the Ethereum platform. It is therefore advisable to explore other options.

Stellar Lumens is one of the most popular blockchain platforms that lets users to design a customized token that forms the basis for an entire ecosystem. In this article, we’ll show you how to create and issue an e-token that is a part of Stellar Lumens. Stellar network.

Step 1: Create two accounts (One for Issuance, the Other for Distribution)

The first step to create an Ethereum token using Stellar Stellar platform involves set up an issuing account that will transfer an amount of tokens to an account for distribution. We set up an issuing account to make it secure after the generation of tokens. We also show our customers that the token supply won’t increase in the near future.

HOW TO BUILD A STELLAR APP?

Blockchain technology has seen a surge in recognition since its introduction to the market. Applications of blockchain in finance like cryptocurrency were among the first uses of this technology. As the world becomes more global and the need for payments across borders grows companies will be pushing for the development of blockchain-based payments.

Our belief is the Stellar Core is one of the most significant distributed technology that permits anyone to build affordable and rapid financial solutions. Our experts in blockchain have been involved in a number of PoCs and have seen the possibilities through Stellar Core.

What is Stellar Blockchain?

The goal for Stellar as well as the group responsible for developing it is to let users transfer money across borders safely and quickly , for fractions of a cent. Stellar connects payment systems with banks, users, and payment systems and enables the transfer of money for free.

With the help of apps or software developed upon Stellar Blockchain, mobile money apps are able to be interoperable , resulting in lower costs for smaller transactions, and increased efficiency.

Stellar Blockchain Stellar Blockchain has an open and decentralized database which allows it to have a verification time of just 3-5 seconds. Since the Stellar blockchain is not written in the Turing full language and therefore, the rate of transactions per second is also very high. Let’s look at an example of how the Stellar blockchain is used to facilitate transactions that cross borders.

For example, you wish to transfer a certain dollar amount to someone (John) who you conduct business with. That person is located in Europe and will be receiving cash in EUR. John’s bank and yours are both connected with Stellar. Stellar network. When you attempt to send cash to John in USD to John the transfer request will be sent out to John’s banks in order to determine whether John is in compliance or not. When you receive the green signal by John’s European bank, the money is taken out of the account of the bank and sent into Stellar. Stellar network in the form of Lumens. When Stellar Lumens are sent to the network, the funds is sent to John’s account and transferred to his bank account.

What kind of products are possible to create with Stellar Blockchain?

  • Peer-to peer payment application You can create a Peer-to-Peer payments application on Stellar Blockchain. Stellar Blockchain that requires minimal charges for transactions and can be faster. By using Stellar Blockchain as the Stellar Platform as your foundational technology, you can allow transactions that are cross-border and low-cost with minimal wait time and with minimal overhead cost.
  • Asset Digitization Digitization of assets is among of the main applications of Stellar blockchain. It assists in digitizing tangible and non-tangible assets that are on Stellar blockchain. Stellar blockchain.
  • Decentralized Exchange Stellar’s blockchain protocol assists in the creation of decentralized exchanges due to the fact that the security of the network is enhanced by having independent servers that have fault tolerance systems are part of the network. The major distinction in Stellar DEX as well as other central and decentralized exchanges, is the fact that it is your responsibility to manage your own funds. Your private keys are in your hands and is only. Contrary to centralized exchanges, in which they store your private keys in central servers or Ethereum exchanges, which are based on Ethereum, and which store them in smart contracts and Stellar DEX allows you to have full control to control your funds. That means that nothing you do, whether hacking into central servers or manipulating smart contracts can cause you to lose your money.
  • Sharing Economy Say that you create an online platform that lets a person who uses mobile data when traveling allows others to use it through hotspots. Since we’re the inventors and advocates of technology, let’s suppose that matchmaking, metering, the rest will go smoothly. But how can the person who shares their mobile information with other people receive a payment for it? This is where blockchain technology comes in , as you are able to develop payment systems using it.

WHAT IS STELLAR BLOCKCHAIN? A COMPLETE GUIDE FOR BEGINNERS

What is common between the top blockchain platforms that are growing rapidly? The answer isn’t difficult when we review of the most popular and new blockchain platforms. Each of the new blockchains are placing on three winning combination – greater speed, scalability, and lower cost of transactions when compared with their older predecessors. Additionally, Stellar blockchain is in the same class. If the emphasis isn’t sufficient in the three areas mentioned above it will be nearly impossible for a blockchain-based platform to gain traction.

What is Stellar?

Stellar is a protocol for payment that is based on distributed ledger system. It facilitates rapid, cross-border transactions among all currencies. It is, in many aspects it’s like other blockchain-based cryptocurrency.

According on the website of Stellar blockchain, Stellar blockchain “is a platform that connects payment systems, banks as well as people” and is designed to “move money fast, efficiently and for nearly free.”

Stellar Lumen (XLM) Stellar Lumen (XLM), the native currency of Stellar that powers the whole operation of the network of blockchain. When the Stellar network 100 billion Stellar Lumens/XLM were created.

The only other way to trigger making XLM can be attributed to inflation. There is a set annual rate of inflation of 1% of the Lumen creation rate in order to reflect economic growth and the loss of Lumens. The new Lumens are created each week and distributed through an indirect voting system.

The Stellar Network vs. Stellar.org

The Stellar network is a distributed ledger technology which facilitates financial transactions. The technology is open source that is distributed and owned by the community.

On the other the other hand, Stellar.org or Stellar Development Foundation is a non-profit organisation which contributes to financial inclusion, creation of social initiatives and tools that revolve around that Stellar network. Stellar employees Stellar create codes to support their Stellar network, however Stellar’s technology is not part of the company.

How Does Stellar Blockchain Work?

As with all blockchain platforms, any transactions made on Stellar’s Stellar network are recorded in an open and shared public ledger. Stellar utilizes an algorithm for consensus built in the Federated Byzantine Agreement (FBA) and is referred to as”the “Stellar Consensus Protocol” (SCP).

SCP helps facilitate quick transactions for less as everyone in the network reaching an agreement on the validity of a transaction within a matter of minutes. Every participant (called”a node) who helps to add entries to the worldwide ledger, selects his/her own mini-network from other trustworthy participants. The mini-networks are referred to as Quorum Slices. The large Stellar network is able to reach an agreement on valid transactions and add them to the ledger fast so long as Quorum Slices are in close proximity.

Where is the Value of Stellar Derived ?

Stellar is an international exchange network that has the capacity to host many exchanges of currency as well as tokens every second. This is why it has an unquestioned value and is of great utility.

Transferring cryptocurrency and/or fiat currencies can be a lengthy and expensive process. Stellar allows it to be quick and inexpensive. XLM (the cryptocurrency used within Stellar Wallet) is the cryptocurrency supported by Stellar Wallet) is used to pay transaction costs and manage your accounts through the Stellar network.

HOW TO SETUP AND RUN STELLAR CORE NODE?

Stellar is an open-source network that connects multiple nodes. They are computers that maintain a shared distributed ledger. To validate and add transactions, the nodes communicate with one other. Stellar Core is an implementation the Stellar Consensus Protocol. It is used by nodes to keep in sync while validating transactions and applying them into the ledger.

Types of nodes

Stellar nodes have the same basic functions: Stellar Core runs, connects to peers, handles transactions, stores the ledger’s status in SQL database, and keeps a copy of it in flat XDR file called buckets. Horizon is the Stellar API that all nodes support. Two key configuration options are what determine the behavior of a node. A node can:

  • Participate in consensus for transitions validity
  • Publishing an archive allows other nodes to access it and view its complete history.

These are the key points that help to classify nodes into the four types of nodes:

  1. Watcher
  2. Basic validator
  3. Validator Full
  4. Archiver

Horizon is supported by all types of nodes. All types of transactions can be submitted to the network. The difference lies in validating transactions, and publishing history.

Watcher

A Watcher is responsible for keeping track of the ledger, submitting transactions and registering them. It is not able to validate transactions or create an archived history. A watcher is not able to contribute to the network or improve decentralization. It is the most lightweight node. A Watcher can pair well with Horizon. If the requirement is for Horizon only, a watcher would be the right option.

Basic validator

A Basic validator provides the same operational requirements as a Watcher and has similar advantages. The basic validator is equipped with a secret key, and can participate in the consensus.

Full Validator

The Full validator is similar to the Basic validator. However, it performs all the same tasks but publishes a history archive that contains the ledger’s snapshots. It is expensive to operate and can be difficult to maintain, but it provides support for the network’s resilience. For a complete history of the network, you can check the archives maintained by Full validators.

Horizon can be supported by Full validator, but organizations that manage them don’t use them to query the network or submit transactions. Watcher is preferred by organizations to manage Horizon.

Archiver

A Full validator is an archiver that publishes network activities but does not take part in consensus. Its utility is very limited. Archives are necessary to support a Stellar-facing Stellar service, such as blockchain explorer. You can referee the network using an archiver, but this is unlikely.

Environment set up

Stellar core can be installed in many ways. You can configure it to join the network at different levels. Watcher, Basic Validator, or Full Validator. No matter how Stellar Core is installed it is essential to connect to a peer–to–peer network, to store the ledger’s status in the database and to connect to the Stellar API, Horizon.

  • Calculate your requirements

Stellar Core PostgreSQL is well-suited for an m5.large AWS server with dual-core Intel Xenon processors and 8GB RAM. Storage-wise, 1TB of storage space is recommended. Stellar Core must be run in conjunction to Horizon. Make sure that your system is equipped for Horizon’s computing requirements.

  • Network access

Stellar Core connects via peer-to-peer networks to keep the ledger synchronized. It is necessary that each node has specific TCP ports open for outbound and inbound communication.

Inbound: Stellar Core’s node allows IPs to connect over TCP to its PEER_PORT. Stellar Core allows you to specify a port while configuring it, but the default (11625), will be used most of the time.

Outbound: Stellar Core will need to connect with other nodes via PEER_PORT and TCP. Stellarbeat has information on other PEER_PORT nodes.

HOW CAN STELLAR BLOCKCHAIN SIMPLIFY CROSS-BORDER PAYMENTS?

Globalization has revolutionized business environment with the increasing amount of businesses and individuals making use of overseas suppliers. This trend is increasing the demand for transactions across borders. The rise in international commerce, ecommerce and internationalization of production shows that the demand for cross-border payments is expected to continue to increase rapidly. A Forrester study forecasts that cross-border eCommerce would span over at least 29 countries in Europe, Asia Pacific, Africa, North America, Latin America, and the Middle East by the year 2022.

The process of sending money from one place to another, be it to relatives, friends or even to pay for goods or services it is more expensive, time-consuming difficult, inconvenient as well as less transparent than regular domestic payments. This could have to do with the complexity involved in payments across borders with more risk and regulations than regular domestic payments.

In order to address these problems blockchain technology is a single-stop solution for improving the overall effectiveness of cross-border payment. A cross-border payment system built on the blockchain platform Stellar will make sure that financial services are accessible to people who have limited or no banking services. These include interconnections with domestic payment systems, expansion of closed-loop systems that are proprietary to boundaries, and peer-to-peer payments systems that are based on blockchain.

What are the problems facing traditional cross-border payment system?

The term “cross-border payment” refers to the process that see the money transferred from one nation and then to a different country. The traditional cross-border transaction consists of several entities such as banks and financial institutions, schemes providers, or even individuals who want to transfer funds across different territories.

When the funds are deposited the funds are processed and transferred through fragmented financial institutions. Each time, the fund’s custody shifts and the institution is charged fees in the range of a certain percentage. This results in increasing costs for the person who is sending. The total charges are calculated based on the amount of transfer as well as the country of destination. The whole process isn’t all that expensive, but it is also lengthy. Because the sender and the receiver do not have a shared ledger, the transaction has to be executed through a number of intermediaries. Payments across borders are essential when purchasing goods and services from one country to the next. But, they aren’t the most convenient option due to:

  • The processing of international payments through banks is complex and difficult.
  • Unpredictable currency exchange rates.
  • The risk of robbery, hacking or theft.

1. Older operational systems

Banks typically encounter the problem of the messaging infrastructure when it comes to cross-border transactions. The majority of payments across borders are made using the SWIFT the MT103 messaging format. It is a reliable format, but can’t carry a lot of information over the limit of. If you require additional information, it’s handled via email. The manual process and non-automated messages in both the transactions render this process inefficient.

2. Inefficient payment processing

Because of a lengthy and complex process that cross-border payments can stop at any time. This can lead to delays and a negative client satisfaction for all parties. The reason for this delay could be the inadequacy of data on the payment as well as the need to conduct sanction checks or AML checks or fraud. Because of the absence of digitization in the data sharing process, transactions have to pass through several sophisticated communication channels.

For instance the transfer of funds between banks internationally is the traditional method to make international payments. Many of the major banks are able to hold a restricted amount of currency. If a sender from the US wants for a transfer of funds into UK. UK however the banking institutions don’t hold enough currency stocks. In these situations they will have to rely on their foreign bank partners for the execution of the transactions. Because the smaller banks don’t have foreign currency, they choose to use large banks to handle the cross-border transactions for them. This is just one situation, however there are many intermediaries involved in these procedures, which can cause delays in transactions.

The majority of B2B international payments are processed by banks. The transaction needs to pass through intermediary institutions such as banks, central banks overseas banks, and the central bank. Each has an accounting system that is independent. This means that the bank accounts require clearing and reconciliation with the other counterparties in a single transaction. This is a slow process which results in the need to take longer processing the transactions.

3. Privacy rules

A majority of banks must adhere to the regulations regarding privacy of personal data. The regulations define which customer’s information needs to be shared across various regions for processing the transaction. The separation, sorting, and arranging of this data takes a considerable amount of time. For instance, in some countries, banks are not able to communicate information about their clients between various departments. This regulation can be implemented with the help of a technological solution to make it easier for the whole procedure.

4. Lack of Security, Transparency and Low Security

Regular cross-border payment uses centralized payment. Customers are required to share their account as well as other details with intermediaries. Based on this information intermediaries process remittances as well as withdrawals. These massive customer data as well as transaction information shared that are shared with intermediaries could be an easy attack for hackers. When using third-party services for transactions that cross borders the transaction information is available across various platforms, foreign merchants and banks. This means that the data is more susceptible to being released in these modes. The parties involved with the transactions can’t keep track of their payments. As a result it is difficult to determine the final amount of payment as well as the time of delivery date.

5. Expensive

Fees are accrued through the bank that sends the money to international and national correspondent banks as well as foreign exchange exchanges at each stage through the process. The cost is typically at least 3 percent for high volume international payments. However, it could increase to 10% if the volume and value of payments aren’t high enough. It is also not clear whether institutions that make payments charge fees to the recipient.

For instance credit cards are a the most popular choice for customers who want to make cross-border transactions. All they have to do is input their card information and wait for their card to be authenticated. It’s a simple process but there’s more that is happening in the background. The cross-border payments require more effort from the credit card networks as well as the involved banks to convert the two currencies. The added workload results in an cost of the transaction which is passed along through the chain of payment.

HOW TO RUN STELLAR API SERVER?

Stellar is a decentralized , open network for sharing and storing funds. Jed McCaleb, the founder of Stellar created Stellar with the intention of providing users with the ability to transfer their fiat currency with digital currency easily.

Developers who create applications on base of Stellar network software making use of Stellar SDKs that they use in their programming languages of choice. SDKs then communicate with Horizon Stellar-network API. Horizon offers a means to verify accounts, join to events, and send transactions.

Stellar ecosystem is based on an API server dubbed Horizon. It functions in the role of an interfacing with Stellar Core and the applications that are part of the Stellar network. It also offers HTTP API for data on data on the Stellar network. It obtains information from data in the Stellar network and serves the data in a format that is simple to access.

There are various benefits for running Horizon with your infrastructure:

  • Control the entire operation without any dependence upon any of Stellar Development Foundation
  • Set up multiple instances to handle capacity and redundancy
  • Enable rate-limiting of requests to ensure access to the network

Prerequisites

Horizon is dependent in the PostgreSQL server to store the data that is processed and ingested by Stellar Core. The PostgreSQL Version 9.5 or greater is required to run Horizon.

The additional RAM required is to host Captive Core’s memory database, which would amount to around 3GB. The second requirement is based on the volume of history of the network that is served by your Horizon instance. It can range from a few GBs up to hundreds of TBs to cover the entire history of ledgers ingested.

Installation

First, prebuilt binaries downloaded from Stellar repositories must be installed prior to installing Horizon. If you’re not keen to install prebuilt releases you can choose another method. It is necessary to build Horizon from source. Some developer tools will must be installed for this purpose:

  • OS that is similar to Unix that uses common basic commands such as mkdir, bash, cp, and so on.
  • Go1.15 or later
  • Git

Configuration

Parameters

Both command line flags and environmental variables can affect Horizon’s configuration. Use the following command to look up the available command-line flags along with their default values as well as the associated environmental variables:

Horizon -help

The command above will show many flags, but only a few are needed. The three most significant parameters are:

  • -db_url: It is the name of the Horizon database. Its value must be an authentic PostgreSQL link URL.
  • -captive-core-config-append-path: It points to a Captive Core configuration stub.
  • -stellar-core-binary-path: It is a file system path to a Stellar Core binary. Horizon scans PATH to find stellar-core automatically; however, if the environment is properly configured then there is no need to specify the path manually.
