The first phase of the internet involved the use of static pages that published information. In the next stage, the internet introduced social media and interactive applications focused on user-generated content. Web3, the latest phase of the internet, relies on smart contracts for creating smart contracts, distributed ledger technologies, and tokenized assets. Let us discover some insights on how smart contracts empower the Web3 ecosystem.

Understanding the Value of Web3

The first thing that you must address while learning about the relationship between Web3 and smart contracts is the definition of web3. It has gained the attention of corporate giants as well as startups worldwide for many reasons. One of the key elements that power the web3 ecosystem is blockchain technology, which helps in promoting the idea of tokenomics and decentralization. 

The impact of smart contracts in Web3 ecosystem depends completely on the involvement of blockchain in Web3 projects. Web3 has achieved significant improvements over web2, such as empowering users with control over their own data. Big companies could no longer profit from the massive collections of personal data of internet users.

Web3 not only provides a decentralized network with transparency and immutability but also provides new avenues for innovation. Blockchain and smart contracts have helped in creating various web3 projects that offer decentralized art, games, finance apps and digital assets. With Web3, users will play an integral role in shaping digital interactions and independent economies.     

Definition of Smart Contracts

Web3 represents a massive leap in the growth of the internet, and smart contracts are a major driving force behind the revolution. What makes these contracts so powerful? Smart contracts are automated programs running on a blockchain network without any intermediaries. Take the web3 smart contract example, and you will notice how it differs from manual contracts. First of all, smart contracts don’t require someone to enforce the terms and conditions of the contract. Therefore, you don’t have to rely on notaries, lawyers, or other middlemen or the time-consuming processes to execute contracts.

You can think of a smart contract as a vending machine programmed to dish out goods according to their price. The vending machine does not require a third party, such as a shopkeeper or retailer, as the intermediary between you and the machine. When the vending machine checks that you have paid the price for a product, it takes the money and gives you the goods to complete the transaction.

Diving Deeper into Working of Smart Contracts

The definition of smart contracts emphasizes more on their identity as self-executing agreements scripted in programs that run on a blockchain. The blockchain protocol or platform where you deploy the smart contract is responsible for providing the infrastructure to execute the contract. For example, Ethereum blockchain provides the Ethereum Virtual Machine or EVM as the infrastructure for running smart contracts. It is also important to remember that smart contracts are immutable and cannot be changed once you deploy them on a blockchain. 

The most common programming languages for writing smart contracts are Solidity and Vyper. If you have created an SOL smart contract, then it will go through rigorous verification process. Subsequently, the blockchain network must reach consensus on validation of the authenticity of the smart contract. Users can invoke the public functions in the contract and the code self-executes and changes state upon meeting specific conditions.

What Value Do Smart Contracts Bring to Web3?

The best way to understand the role of smart contracts in the world of Web3 is through an overview of their benefits. Smart contracts bring the assurance of the following advantages that make them the founding blocks of web3.

• Trustless Nature and Immutability 

The foremost aspect of smart contracts that answers questions like “What are smart contracts in web3?” is their trustless nature. Smart contracts run on the basis of design rather than following authority. You don’t have to trust anyone else to complete a transaction with smart contracts. On top of it, deploying smart contracts on a blockchain ensures immutability that enhances the security and integrity of every web3 transaction.

• Cost Reduction 

The removal of intermediaries according to principles of decentralization in web3 happens due to smart contracts. Without the involvement of intermediaries, you can notice dramatic drops in operational costs. Smart contracts help in bypassing notaries, banks, and lawyers to offer peer-to-peer transactions. As a result, smart contracts help in making various processes in the web3 space more efficient and leaner. 

• Faster Transactions 

The next important reason for which smart contracts are an inevitable part of web3 is the assurance of faster transactions. Smart contracts facilitate automation that makes transaction settlement faster, almost in real-time. The smart contracts web3 relationship ensures that web3 transactions don’t depend on third-party approvals. The self-executing agreements will execute certain conditions of transactions when they notice compliance with predefined rules.

The biggest problem with traditional financial systems is the centralized nature of operations, which slows down transactions. On top of it, traditional finance is inaccessible to millions of people on the planet. Another drawback of traditional finance is the reliance on intermediaries, which leads to higher costs and more inefficiency. 

The proven solution to these problems will be to write smart contract for Ethereum or any blockchain of your choice for a DeFi application. Smart contracts serve as the driving force behind many popular DeFi platforms that offer peer-to-peer financial services. Smart contracts help in automating different DeFi services such as lending, insurance, and trading, alongside ensuring secure transactions.

Considering the role of DeFi in the Web3 ecosystem, it is reasonable to believe that smart contracts will redefine the boundaries of financial services. With the help of smart contracts, DeFi platforms in the web3 space can allow anyone to participate in global financial markets. 

• Non-Fungible Tokens 

Non-fungible tokens or NFTs, are another prominent offering in the web3 space alongside DeFi solutions. The popularity of NFTs has shattered many conventional ideas about digital assets and their ownership. As NFTs emerge as one of the vital elements for the economies of Web3, it is important to acknowledge how smart contracts drive NFTs. Non-fungible tokens use smart contracts to represent the ownership of digital assets on a blockchain, thereby maintaining a trail of ownership.

You might wonder about the feasibility of smart contracts in the domain of web3 with respect to NFTs. Interestingly, NFTs are in web3 for the long run as they bring a new experience of digital art, virtual real estate, and gaming. The use of smart contracts in Web3 ecosystem has brought new privileges for users to create and sell NFTs. On top of it, smart contracts also help in building NFTs that represent in-game assets which players can own and trade.

What is an Escrow Smart Contract?

While discussing the core concepts of blockchain technology, a common question that may arise in one’s mind is – What is a smart escrow contract? By finding an answer to the question you can get a thorough insight into how transactions take place within blockchain networks. Escrow involves a third party or a neutral party that is responsible for holding the assets in the presence of two parties, i.e., buyer and seller.

Before engaging in a transaction, participants transfer their tokens to an escrow smart contract. In blockchain escrow smart contract, the deposited tokens are held until the requisite payment conditions have been fulfilled. The reliance on an escrow account smart contract arises since the involved parties need to make sure that the delivery of the agreed product or service takes place and the appropriate payment is done.

Hence escrow blockchain acts as a security blanket for users who take part in transactions within blockchain networks. The primary purpose of blockchain escrow smart contract is to ensure that one of the involved parties does not default at the expense of the other involved party.

An escrow smart contract example involves a seller who wishes to sell his smartphone. It also involves a buyer who intends to buy a smartphone from the seller. For taking part in the exchange process, they will contact a neutral party. It will be responsible for holding the assets or tokens until the buyer receives the smartphone.

Once the buyer receives the intended goods as per the agreed terms the release of the tokens or assets to the seller is possible. The simple escrow smart contract example gives a glimpse into how these contracts work in the blockchain ecosystem.

Key features of an Escrow Smart Contract

Now that you have the answer to the question – What is a smart escrow contract? It is time to identify its key features. The chief features of escrow smart contracts make them an indispensable element in the blockchain environment. Some of the features of the blockchain escrow smart contract are:

• It involves a third party that holds the funds on behalf of the participants who partake in the transaction. 
• The disbursement of the funds takes place only after the agreed conditions between the parties are met.
• The purpose of having such a contract is to curb the possibility of fraud or default for the parties.   
• An escrow account smart contract does not depend on any central authority. This is because the contracts are self-executable once necessary terms are satisfied.
• The relevance of escrow blockchain is immense since it boosts elements such as efficiency, transparency as well as trust while engaging in blockchain transactions.

Need to create an Escrow Smart Contract

If you plan on transacting within blockchain networks you must certainly create an escrow smart contract. In escrow smart contract solidity serves as the chief programming language. Once you have the financial agreement in place you can take part in safe and secure transactions. You do not have to worry about getting duped by any malicious party or fraudulent.

The use of solidity is common for developing smart contracts. Hence you can make use of the programming language to develop Escrow smart contracts and participate in transactions securely. In your escrow smart contract solidity can ensure that the contract serves the intended purpose and provides complete transparency as well as security to the involved participants.

The absence of a blockchain escrow smart contract is a poor move for a participant who wishes to transact with another party within the blockchain network. This is because it can increase their vulnerability. Furthermore, the possibility of being cheated may escalate significantly.

How does an Escrow Smart Contract work? 

A series of processes take place involving an Escrow Smart Contract when transactions take place between parties within blockchain networks. It has already been discussed that a blockchain escrow smart contract is chiefly responsible for holding funds until and unless the requisite payment conditions have been met. 

Stage 1 

In the initial stage when two parties decide to take part in an exchange process, they need to specify the payment procedure. Additionally, the parties have to make sure that they state the proper conditions at this stage. These elements together make up an integral part of an escrow smart contract. The specification as well as the deployment of the smart contract may be made either by the buyer or the seller. 

Stage 2 

In the next stage, the buyer has to transfer his tokens to the blockchain escrow smart contract. The purpose of making the transfer is to send it to the seller on receiving the intended item from it as per the agreed terms and conditions. 

Stage 3 

Then the seller has to make sure that the token release conditions that have been set by them are met. In order to meet the conditions, the seller has to focus on delivering the desired service or product to the buyer. The information relating to the specific event that takes place between the buyer and the seller has to be shared with the escrow smart contract.

Stage 4 

In the final stage, the escrow smart contract has to ensure the validation of the pre-defined conditions. Once the validation process is complete it will release the tokens of the buyer to the seller. In case the respective event that takes place between the buyer and the seller is not informed within the appropriate time then the tokens will be sent back to the buyer. Similarly, if the escrow smart contract receives the information that the product or service has not been delivered to the buyer according to the set terms, the tokens will be sent back to the buyer. 

Benefits of Escrow Smart Contract in Blockchain

The use of an escrow smart contract in blockchain gives rise to a broad range of benefits. Below are some of the chief benefits of Escrow Smart Contract that can help you explore the concept at a comprehensive level. 

• High level of trust as well as security 

The chief benefit relating to an escrow smart contract revolves around high trust and security. By having such a smart contract in place, the risk relating to fraud can be reduced considerably. An escrow smart contract boosts the confidence of buyers and sellers to take part in different transactions within the blockchain network. 

Since these contracts involve a neutral party, buyers can breathe a sigh of relief and do not have to fear that they will lose their tokens. The improved level of security undoubtedly enhances the trust factor between the involved buyers and sellers in the blockchain realm.

• Transparency 

The participants that exist within blockchain networks expect to have a high level of transparency. Escrow smart contracts make sure that there is no compromise in terms of transparency for participants who take part in exchange transactions in the blockchain setting. The operations and processes that take place are conducted in a transparent manner. Therefore all the appropriate participants can see the transactions that take place. 

• High efficiency 

Another important advantage relating to escrow smart contracts in Blockchain is high efficiency. Blockchain eliminates the need to involve any centralized authority. As a result the transactions take place in a highly efficient manner. Hence it helps to keep a tab over transaction costs while ensuring efficiency of the services. 

The role of escrow smart contracts in blockchain is of high value. It gives rise to a broad range of benefits for both buyers as well as sellers. These smart contracts enhance trust, security, transparency and efficiency for users who partake in blockchain transactions.

The Solana Program Library, or SPL, is a comprehensive collection of libraries and tools tailored for supporting dApp development on Solana blockchain. In technical terms, the SPL is a collection of on-chain programs that target the Sealevel parallel runtime. The on-chain programs go through testing with respect to the Solana implementation of Sealevel.

Solana maintains the Solana Program Library, or SPL, as a comprehensive and dedicated documentation library. The answers for ‘What is Solana Program Library’ would focus on how SPL includes all the pre-compiled, deployed, and optimized programs on Solana blockchain. It is important to note that smart contracts on Solana blockchain take the identity of programs. Let us learn more about the Solana Program Library and SPL token program in the following post.

Build your identity as a certified blockchain expert with 101 Blockchains’ Blockchain Certifications designed to provide enhanced career prospects.

What are Solana Programs?

The first thing you need to learn Solana program library is a detailed understanding of Solana programs. Solana programs are automatically executable code that you can find in buffer storage. In Solana blockchain, accounts serve as the buffer storage for Solana programs. On top of it, users can execute programs through transactions just like smart contracts on Ethereum or other programmable blockchains.

However, Solana has a resource-efficient approach for smart contract execution compared to other programmable blockchain networks. In Ethereum, smart contracts store the smart contract program and its state together. On the other hand, Solana uses a stateless program model and accounts to help store data and programs.

Significance of Accounts in Solana

The guides for understanding Solana programs would be incomplete without a description of accounts in Solana. You can learn more about the Solana SPL token program by discovering the meaning of accounts in Solana. Accounts are a type of record in the Solana ledger that can hold data or also serve as executable programs.

If you think that Solana is a database, then the accounts in Solana serve as rows. In addition, pub keys serve as IDs, and the value in the rows points to the information you can find in the account. The information in the rows can be found in the form of programs or smart contract codes and the data or state of the program.

You can identify an account with the help of a unique Public Key, which is 256 bytes in size. Solana offers logical separation between the code and data associated with it, thereby leading to the creation of two distinct variants of accounts. The common types of accounts you can find in a Solana program library example include executable and non-executable accounts. Each type of account has distinct traits, which makes them invaluable additions to the Solana ecosystem.

Executable accounts are accounts that store only the immutable smart contract or program code on Solana.

On the other hand, non-executable accounts also store the data that the related program would need. For example, it would store variables, states, and assets of the program. Anyone can read the data in non-executable accounts. However, only the owner of the program has the right to modify data in non-executable accounts. A comprehensive Solana program library guide could also highlight the fact that only validator nodes could maintain the accounts.

The validator nodes would charge a maintenance cost known as ‘Rent’ for offering memory space to store the required information. Users can pay the ‘Rent’ in the form of lamports, which are the fractional denomination of SOL, the native token of Solana blockchain. At this point, you must learn about Sealevel Parallel Runtime system that helps in maintaining the Solana program code and state data separately.

Excited to learn about the fundamentals of Solana and Solana smart contracts development, Enroll now in the Solana Development Course.

Importance of Sealevel Parallel Runtime

Sealevel Parallel Runtime is the most important component in the Solana ecosystem. It is Solana’s unique approach to implementing a parallel transaction processing system. Sealevel parallel runtime is a valuable component for Solana SPL token program execution and powers the Solana Program Library.

In the case of traditional single-threaded blockchains such as Ethereum, processing transactions one at a time can help avoid concurrency. It is important to note that Ethereum smart contracts are stateful in nature, which implies that the state and the code can be combined in the same contract.

Sealevel Parallel Runtime can help Solana in processing thousands of transactions in parallel without any conflicts. Solana can leverage multiple validator cores and execute almost 50,000 TPS along with a 400 millisecond block time. The tasteless nature of transaction instructions ensures that they can decide the account data for modification. Therefore, Solana programs that do not have the same account data could run simultaneously.

Notable Variants of Solana Programs

The journey to learn Solana program library fundamentals also involves familiarizing with the notable variants of Solana programs. You can find two variants of programs in the Solana ecosystem, such as native and on-chain programs. Let us learn more about the two variants of Solana programs in detail.

• Native Programs

Native programs are useful for implementation of core functionalities of Solana network. The core functionalities of the Solana network include creation of new accounts, enforcement of the rules of Solana network, management of allocation of account storage, and transaction processing. Native programs are integral components of Solana’s core blockchain model.

Low-level languages such as C/C++ and Rust help in creating native programs. The native programs are optimized to achieve better security and performance, and any program or user can call native programs. On the other hand, users cannot directly call or access a kernel-level program in your operating system.

Updating the native programs could happen only as a result of the cluster upgrades or core blockchain upgrades. The upgrades could focus on improving performance, adding new features, and fixing bugs. Every Solana program library example could help you understand how native programs could help in securing the validator. Some of the notable variants of native programs on Solana include system programs, stake programs, and Berkeley Packet Filter or BPF programs.

System Programs

The primary functionality of system programs revolves around creation of new accounts, assignment of account ownership, and transferring SOL tokens between accounts. In addition, system programs are useful tools for performing many other account management tasks in the Solana ecosystem.

Stake Program

The stake programs in Solana ecosystem can help in management of the process for staking SOL tokens on Solana blockchain.

Berkeley Packet Filter

The Berkeley Packet Filter or BPF programs are useful for managing the process of deploying and implementing upgrades and the on-chain execution of programs.

• On-chain Programs

The next important category of programs in the Solana ecosystem points to on-chain programs. Any Solana program library guide would be incomplete without mentioning the details of on-chain programs. The on-chain programs are user-scripted programs deployed directly on Solana blockchain. Some notable examples of on-chain programs include dApps, crypto exchanges, test smart contracts, multi-sig wallet implementation, and other generic programs.

As compared to native programs, on-chain programs are not a part of the core of the Solana cluster. On the contrary, they are custom programs developed and deployed directly on Solana blockchain. On-chain programs are not the essential requirements for operations of Solana blockchain.

The programs are developed over the core infrastructure developed by the native programs and help in creating a broad range of applications or services on Solana. Separate data accounts are required for storing the data with which the programs interact. The data could be passed as references through instructions, and the account owner could help upgrade the program data.

Core Functions of the SPL Token Program

The noticeable aspects you must focus on to learn Solana program library fundamentals would also include the SPL token program. The SPL token program serves as a generic implementation for non-fungible and fungible tokens on Solana blockchain. It offers an interface alongside detailed implementation that allows developers to create their own tokens. The code for SPL token program is written natively in Rust and also leverages the benefits of auto-generated bindings in JavaScript and C. You can access the source code for the SPL token program in the SPL Github repository.

You can understand the difference between Solana SPL token program and ERC-20 token program to learn more about their usability. The ERC-20 token program has a different working mechanism than Ethereum ERC-20 contracts. For example, you can try to publish three different tokens on Ethereum blockchain by deploying three different contracts. Every token contract would maintain track of the balances and transfers associated with the contract.

On the other hand, you don’t have to deploy three different token programs on Solana. You can only use one generic token program that would work on different types of accounts. The mint address supports the unique identification of the token type. In addition, users can pass the information as arguments to single static ERC-20 program instances deployed on Solana blockchain.

An Insight into Gas Optimization is Solidity

Solidity is the programming language that has been designed for developing smart contracts. While using Solidity, one has to be familiar with the concept of gas as well as gas optimization. Gas is basically the measurement unit of the volume of computational effort that is needed for performing certain operations on Ethereum. 

Solidity gas optimization involves the processes and practices to minimize the cost of Solidity smart codes while executing them. It is essential to prioritize gas optimization solidity to keep a tab on the cost aspect and support sustainability.

Are you aspiring to learn the fundamentals of the Ethereum Virtual Machine and smart contracts’ upgradability? Enroll now in the Advanced Solidity Development Course.

Top Solidity Gas Optimization Techniques 

Now that you know the importance of gas optimization in solidity, it is time to focus on some key techniques. The main question that may be bothering you is – How to optimize gas in Solidity? Below are some of the top solidity gas optimization techniques that can help answer the question.

• Substituting Arrays with Mappings

Arrays and maps are the two data types that can help describe the data lists in Solidity. It is quite common to use the array data structure while using Solidity. However, did you know that it increases the level of gas substantially. The issue can be minimized by using maps in the place of arrays. By doing so you will be able to save more than 2000 gas on every reading. This feature of mapping makes it a much affordable option in comparison to arrays. It is among the most popular solidity gas optimization techniques that you can use.

• Reducing on-chain data

By reducing the data that has been recorded on a chain you can minimize the consumption of gas. When the volume of data is less, there is the need for less storage for storing variables. As a result, there is an opportunity to minimize the gas that is required for your smart contract. A simple trick that you can follow involves making use of events for storing off-chain data instead of using the on-chain data storing option. It is certainly one of the best techniques to optimize solidity gas.

• Utilization of constants as well as immutable variables 

A smart way of gas optimization in Solidity involves making use of constants and immutable variables. This step can obviously help you reduce gas costs to a considerable degree. These variables are ideal choices since they do not consume a lot of storage space within Ethereum Virtual Machine. 

When constants and immutable variables are used, the allocation of values takes place solely during the creation of smart contracts. Furthermore, they subsequently become read-only. Hence these variables have high cost-effectiveness when compared with regular variables. 

Familiarize yourself with the complete Ethereum smart contract development lifecycle and gain fluency in the best practices for smart contract coding, testing, and deployment with Smart Contracts Development Course.

• Use of Solidity Compiler Optimizer

One of the top solidity gas optimization techniques involves enabling or using Solidity Compiler Optimizer. Its role is vital since it helps to transform complex expressions into their simpler versions. Hence it leads to the reduction in the size of the codes. That’s not all! The execution cost, deployment costs as well as costs relating to function calls gets lower. It is a useful strategy that can facilitate gas optimization solidity.

• Optimization of Unused variables 

One of the most popular solidity gas optimization techniques is optimizing unused variables. There are many times when irrelevant or unnecessary variables are kept while executing smart contracts. This is a poor practice which ends up increasing the overall gas costs. By removing the unused variables, smart contracts can get optimized, thereby reducing gas costs. This technique is crucial since it can help you free up the space that remains unused.

• Utilizing Indexed Events 

Events are an important part of blockchain. The role of events is essential since they allow users to know when something takes place within the blockchain network. In solidity, events serve as the ultimate shortcuts that increase the speed of smart contracts as well as working of external systems. By having indexed events in place there is an opportunity to keep track of all activities relating to a smart contract in an efficient manner. By using indexed events, it is possible to reduce the overall gas that is consumed. 

• Replacing dynamic sized arrays with fixed size arrays

One of the best techniques to optimize solidity gas is to use fixed size arrays instead of dynamic size arrays. In case it is a must for you to use arrays in your Smart contract, you can opt for the fixed size versions. One of the main limitations of dynamic size arrays is that they may expand indefinitely. Because of this the gas cost may substantially increase. However this problem does not arise when it comes to fixed size arrays. Due to the fixed nature there is no risk relating to the indefinite expansion of array and gas costs.

• Avoid the use of lower than 256 bit variables

The variables that you use in Solidity can have a direct impact on the gas that is consumed. You must avoid using variables that are lower than 256 bit. In case you use uint8 you need to know that it is a highly inefficient option. Instead you should opt for uint256 in Solidity. It is a much more efficient approach that will help you minimize gas costs by ensuring gas optimization.

• Utilizing External Visibility Modifier

When it comes to Solidity, it is instrumental to use the most suitable visibility for diverse functions. It can certainly serve as an effective measure that can help in the optimization of gas that you need while creating smart contracts. You must keep in mind that choosing an external visibility modifier is one of the best options that you can consider. It is highly gas efficient in comparison to the public option. 

Gas optimization is low in the case of public functions. This is because in the case of public functions, it has to support external as well as internal calls. However in the case of external functions, it can read only from calldata and hence there is no need for copying data to memory. This feature makes it a useful gas optimization technique. 

• Using storage pointers instead of memory 

Wherever applicable, you must use storage pointers instead of memory. Storage pointers, in Solidity, are the variables that reference a specific location in storage of a smart contract. You need to know how to make the efficient use of storage pointers so that you can avoid irrelevant storage reads. It is surely a gas efficient approach that can help you minimize gas costs in solidity. 

The higher the memory, the greater will be your gas costs in Solidity. You should try to reduce the overall usage of the memory while developing smart contracts in the Ethereum blockchain network. By capitalizing on storage pointers you may not only save memory but also optimize gas in Solidity. 

The identification of the different Solidity gas optimization techniques can certainly help you address the question – How to optimize gas in Solidity? As the rising gas costs can be really burdensome you must consider the given techniques to optimize gas use and reduce gas costs. The simple techniques can enhance your ability to leverage Solidity while developing robust smart contracts.
