Web3 smart contracts & blockchain development

A Beginner's Guide to Web3 Smart Contracts

Understanding Web3 smart contracts and blockchain development

So, you are interested in web3 smart contracts and blockchain development? Get prepared as we look into this intriguing topic.

Blockchain technology has revolutionized how we perceive trust and security in digital transactions. It is a decentralized ledger that records transactions across multiple computers, ensuring transparency and security. One of the most groundbreaking innovations within blockchain is the advent of smart contracts.

Smart contracts are self-executing contracts with terms and conditions written into code. They automatically enforce obligations and simplify complex processes, eliminating the need for intermediates. They play a crucial role in blockchain by providing automation, ensuring clarity, and making sure no changes can occur.

Technical Aspects of Smart Contracts

Depending on the blockchain platform, smart contracts are programmed using languages such as Solidity, Vyper, and Chaincode. Solidity is the most popular for Ethereum-based smart contracts.

Smart contracts interact with the blockchain by being stored on the blockchain itself. When a transaction occurs, the contract by design completes the specified terms, and the result is added to the blockchain.

For security, smart contracts have measures such as encryption and decentralized storage. That does not make them immune to vulnerabilities. Therefore, their security largely depends on the quality of the code input by the blockchain developer and the precautions used during development.

Potential Applications of Smart Contracts

There are many web3 smart contracts case uses, and more are created at an amazing pace across multiple industries.

For example, they can automate payments and insurance claims in finance, reducing fraud and delay. The supply chain industry can use them for traceability and authenticity verification. In real estate, they can streamline property transactions, reducing paperwork and fraud.

Real-world examples include AXA's flight delay insurance. This insurance automatically reimburses customers if their flight is delayed. De Beers uses smart contracts to track the journey of diamonds from the mine to the customer, ensuring authenticity and ethical sourcing.

Challenges in Smart Contract Development

Don't think, however, that web3 smart contracts don't have their issues with limitations and security.

Because all actions and events occur as a result of set actions, smart contracts cannot access off-chain data without external help. There's also the 'garbage in, garbage out' problem – if your coding is incorrect, your output will also be wrong.

Moreover, security vulnerabilities are frequently evident. Blockchain smart contracts are subject to attacks. An article in Wikipedia explains,

"The DAO was a digital decentralized autonomous organization (DAO) and a form of investor-directed venture capital fund. After launching in April 2016 via a token sale, it became one of the largest crowdfunding campaigns in history."

2016 was The DAO's downfall. "...Users exploited a vulnerability that enabled them to siphon off one-third of The DAO's funds to a subsidiary account."

To ensure this doesn't happen again, developers must apply rigorous testing and code auditing. Utilizing blockchain platforms with enhanced security features and superior coding practices is also essential.

Future of Smart Contracts in Blockchain Development

Did you know that the global smart contract market size is currently around US$315.1 million and is projected to reach $1.46 billion by 2028?

Emerging trends in smart contracts include interoperability, enabling interaction between different blockchains, and the rise of Decentralized Finance (DeFi), which heavily relies on smart contracts.

These advancements could lead to mass adoption of smart contracts, making them a standard for digital agreements. The potential impact on the blockchain industry is profound, with smart contracts expected to drive the next wave of blockchain innovation.


With their ability to automate and secure digital transactions, Web3 smart contracts represent a significant advancement within blockchain technology. While they face challenges, particularly regarding security and data limitations, the solutions and progress in this field are promising.

 The importance of smart contracts in blockchain development cannot be overstated. They are likely to play a central role in the evolution of blockchain, enabling a future where digital transactions are seamless, transparent, and secure.

The Reality Check on NFTs: Investment Treasure or Overhyped Bubble?

I know what you're thinking. 

You've seen the headlines, heard the buzz, and watched as digital currencies and NFTs garner attention—and, let's be real, a substantial amount of wealth. 

Suddenly, that kid next door, the one with the perpetually unkempt hair and an unhealthy obsession with video games, is a cryptocurrency millionaire. Your college buddy who couldn't hold a job is now sipping margaritas on a private island, thanks to his early investment in NFTs. 

It's enough to make you think you've missed the boat, isn't it? Makes you feel like you're standing on the dock, watching as everyone else sails off into the sunset of financial freedom. 

You're tempted. 

But then, there's that nagging doubt. Is it all just smoke and mirrors? Is this another bubble, destined to burst and leave its investors high and dry? 

Well, according to a recent study, your spidey senses may have been right.

Worthless Jpegs?!

In the whirlwind of the digital age, Non-Fungible Tokens (NFTs) emerged as one of the most talked-about innovations, captivating audiences with the allure of unique digital ownership. 

From incredible art pieces to tweets, everything seemed to have found a new dimension of value in the world of NFTs. However, a recent study punctures the enthusiasm and presents some sobering insights into the real state of the NFT market.

A substantial finding of the study is that a staggering 95% of NFTs have become virtually worthless. This startling statistic upends the once widely held belief that NFTs were the golden tickets to lucrative investment opportunities.

So, what's the cause behind this sharp depreciation? A leading culprit, as pinpointed by the research, is the oversupply in the NFT market. It's a classic economic scenario of too much supply with too little demand. 

The digital marketplace has been deluged with numerous NFT projects, and unfortunately, not all of them are of discernible quality or purpose. With this glut, capturing consumer attention and driving sales have become Herculean tasks, dragging down the value of many tokens.

Furthermore, a striking observation from the study is the decline in the high valuations that NFTs once boasted. To put it in perspective, less than 1% of current NFT listings have a price tag beyond $6,000. 

This underpins a prevalent issue: sellers might be inflating their NFT prices, but without genuine demand to back them, this only serves to skew the true value of these tokens.

The overarching takeaway for potential investors is clear: tread carefully. While tales of NFT riches are not entirely myths—with sectors like gaming and art showcasing some prosperous projects—the broader picture reveals that the majority of NFTs hold a value under $200. 

A Glint of Hope

That said, it's not all doom and gloom for NFT enthusiasts. Despite the overarching depreciation, the inherent value proposition and uniqueness of NFTs remain intact. 

The potential exists. 

But the key lies in discernment. A proactive approach involving meticulous research and staying abreast with the latest trends will be paramount in identifying the diamonds in the rough.

All in All…

In wrapping up, this study serves as an eye-opener to the state of NFTs—highlighting that while 95% of tokens may have lost their sheen, the market itself isn't devoid of potential. Success is achievable, but it mandates caution, diligence, and informed decision-making. As the digital world continues to evolve, so will the opportunities within the NFT landscape, making it an intriguing space to watch and explore.
