The following is a guest post of HLIB Rabchuk, PR -Manager at Ethereum Ukraine.
Web3 evolves with breakneck speed – new protocols are created, developer trends shifting and the skills that are in question today can be outdated tomorrow. For those who navigate by industry, it is not just about technical expertise; It is about understanding where the space is going.
Yurii KovalchukWeb3 Engineer at Forte Group and Blockchain Development teacher at Set Universityhas seen these shifts first hand. With more than nine years in it, to distribute Java back-end development to leading teams in web3 startups, he offers a unique perspective on how industry has changed and where it goes.
From the rise of peace and ai-integrated web3 solutions to blind spots that still developers bullying-this interview unpacks the reality of building in web3 today. Whether you are a developer, investor or just a curious spirit who wants to understand the space, offer Yurii’s insights a rare view of the challenges and opportunities that shape the future of blockchain.
Web3 Labor Market: How has the industry changed in the last 5 years?
– How different is the question for Web3 specialists today than 5 years ago? To which courses should an average student developer pay attention to work in web3?
Yurii: Five years is a whole era for web3. This period is too sustainable for evaluating changes as the market develops in fast cycles.
5 years ago, for example, we didn’t even know what Defi was. Now it is one of the most important components of Web3. But when we talk about the current trends on the labor market, these are the most important points I see:
- High demand for rust developers. The popularity of Solana has increased, as well as the demand for specialists who can actually write in rust.
- Web3ing engineers with an understanding of AI. The AI-agent space is developing quickly and there is a demand for AI integration in web3 protocols.
- Security researchers. A new wave of AI-related attacks is expected, so auditors and security specialists are wanted even more.
- Developer relationships. This role that helps to build a bridge between projects and developers is becoming increasingly important as web3 goes beyond the narrow technical community.
- Marketers with an aggressive style. Web3 has a very specific marketing style that requires flexibility and volume. The usual methods do not always work.
- Community managers. Web3 projects are highly dependent on the community and decent community management becomes crucial.
Solana vs. Ethereum: Where is one technology for the other?
– What does Solana do that Ethereum has not yet succeeded? Are there changes that can correct this imbalance?
Yurii: Solana indeed has an advantage in the field of transit and low costs. All because of the architecture, so that it can reach thousands of transactions per second without the need for extra scale layers.
Ethereum, on the other hand, builds a more decentralized and trusted infrastructure, making it safer and more sustainable in the long term. Layer 2 solutions are actively developed and Ethereum has already considerably improved performance.
With future updates, Ethereum Solana will be able to overtake in terms of transaction speed and costs.
But whether Solana will be able to achieve the same stability and decentralization as Ethereum is an open question.
A critical security error is made in web3
– You often refer to the importance of security on your blog. What is a common security error that Web3 developers still make?
Yurii: The biggest mistake that both developers and users are still making is still not managing private keys properly.
Yes, the joke about the private key assignment on Github is still relevant because it is only partially true. People often store seed sentences, private keys and other sensitive information incorrectly, whereby hardware portfolios and extra signature controls are neglected, leading to hacks, phishing and activation theft.
Access management in smart contracts comes in second place. This is the main cause of Web3 protocolhacks, because many developers leave excessive administrative rights or wrongly implement contract -updated mechanisms.
As a result, owners can lose control of the protocol or hackers can gain access to critical functions.
Web3 continues to evolve, but basic security errors are still the cause of the biggest attacks and hacks.
Web3 needs a rebranding. But what kind of rebranding?
– you recently stated That Web3 needs a new positioning. Which specific aspects do you think should be changed?
Yurii: I do not believe that “web3” needs when term rebranding -the image is still quite positive and not -not -not.
The need for change is more related to the concepts of crypto And blockchain.
Crypto today has a very speculative and negative image because of the large number of people trying to abuse the system and easily chase money. Blockchain, on the other hand, is seen as an outdated and archaic term, and sometimes even automatically identified with cryptocurrencies, which creates the wrong impression. This can only be corrected by education and the right communication.
On my social media pages I always explain that these three concepts – web3, blockchain and crypto – are all completely different things.
That’s why, Blockchain is a technology, Crypto Is one of the use cases, and Web3 Is a very paradigm of the new internet, with which you have your data and assets.
This approach should help to shape the right perception of Web3 among the massive public.
Pectra: What is it and why is it important?
– The Ethereum Pectra Hard Fork will take place on 24 February. What key changes does this update bring, and what new opportunities is it open for the Ethereum Ecosystem and its developers?
Yurii: The Pectra Hard -Vork is another important step in the development of Ethereum, which combines two important offers: Prague for the version and electricity for the consensus layer. This will be one of the largest Ethereum updates in history (in terms of the number of EIPs). There are three main areas that are worth mentioning:
- User experience (EIP-7702) is a new approach to temporarily convert EOAs (external ownership accounts) into smart contracts, which significantly improves UX and brings us closer to Real Account Abstraction (AA). This opens opportunities such as transaction batching, payment of committees using ERC-20 tokens and different levels of account access.
- Validators work (EIP-7002, EIP-7251). Validators will be able to withdraw their income and start ETH independently, making the process more flexible and faster. Moreover, the maximum amount for setting by one validator will increase from 32 ETH to 2048 ETH. This simplifies management for large strikers and reduces the number of validators in the network while retaining decentralization.
- EIP-7691 Increases the maximum number of Blob data in a block to 9 (formerly 6) and the target number to 6 (formerly 3), which temporarily improves the transit of Ethereum for Rollup solutions until Peerdas is implemented. EIP-7623 increases the costs of calldata by encouraging rollups to use blob data, which is a more efficient way to save them.
Do developers still create market trends?
– You are currently participating in the Uniswap Hook Incubator. Since the dominant market stories are formed by developers, is it possible to predict market trends in such a community?
Yurii: Yes, I am currently completing an incubator program that is being carried out by the Uniswap Foundation & Atrium Academy. In it we deeply explore the possibilities of Uniswap V4 and the most important function – Hooks.
This version offers endless possibilities for AMM adjustment, including dynamic costs, MEV protection, flexible mechanisms for liquidity management, with which you can not only build add-ons to Uniswap, but full protocols on it.
Moreover, Uniswap does not only set a vector in Defi. Projects such as Flaunch, a launch path for memecoins with a fair auction,, for example, show that its application goes much further than the traditional Dex.
I think The next major trend is the deeper modularity of Defi protocols and the integration of adapted mechanics in liquidity. With V4 you can create products with your own algorithms for prices, asynchronous exchange and flexible liquidity management, which the Defi market can change considerably in the coming years.
Memecoin Automation: A new chance or a risk bubble?
– The recent launch of Pump.Fun on mobile devices has made it clear that making memecoins is easier than ever. Your projects of the last two hackathons simplify this process too. Is there a risk that this convenience will lead to token issue A huge bubble? Will web3 not be a fast food industry?
Yurii: One of our projects has indeed really simplified the creation of Memecoins by using AI agents.
We saw that Memecoins and AI are currently two of the most dynamic areas in web3, so we have decided to combine these trends by exploring their synergy and possible impact on the market. The convenience of creation will certainly lead to an increase in the number of tokens, and not all will have a good basis or use. However, I do not believe that the fight against projects should be of low quality to make it artificially difficult to make them.
Web3 is still improving the user experience, and our task is to make it more accessible to newcomers. Restrictions and barriers are not the answer – it is more important to teach people to distinguish quality and understand value.
It is just like food: instead of banning fast food, we teach children to choose healthy food. Web3 should do the same – No block, but increase consciousness.
Memecoins vs. Trust in Web3
– Does Memecoins discredit the web3 industry in the eyes of people who want to become developers and investors? How do the events around Libra, $ Trump, CZ and other similar cases influence confidence in technology?
Yurii: I don’t believe that Memecoins discredit the web3 industry as a class of tokens. They can have healthy mechanics and utilities. See them as promotional flyers or a PR campaign for a project.
If you want to quickly attract the attention of the public and form a community, Memecoins can play this role effectively. Moreover, Memes are closer to a wide audience – both for ordinary users and enthusiasts who want to launch something of themselves, even if it is of a fan.
Regarding the discredit of Web3 in general, this problem does not only apply to memecoins. Every project of which is the most important goal to mislead users damages the reputation of the industry. Whether it is a memecoin or a layer of 1 -blockchain that only existed on paper, collected millions by an ICO and disappeared, the principle is the same. Yes, due to the ease of making token, this tool has indeed become more accessible to scammers and rags happens more often. But as in the previous question, the solution is not in prohibited but in education.
Dyor (do your own research) remains an important principle for all Web3 participants.
