Web3 from Dev Relations Engineer point of view

Public Key Infrastructure
Until the 1970s, symmetric encryption was the only type of encryption we know of. Like the lock with multiple keys, when using symmetric encryption, the sender sends a message encrypted with a key, and the receiver must hold the identical key to decrypt a message. In cryptography, we usually introduce Alice and Bob as the sender and the receiver. Alice and Bob must either meet physically or use some of the key exchange algorithms for both of them to have a copy of a secret key. This brings

Why do we need Account Abstraction?
As time flies, us humans are less satisfied with our inventions than we were when we conceived the idea. We are streaming to making things better with every iteration, and that’s precisely what makes us both imperfect and imperfect beings; at the same time, struggling to find peace within ourselves and feel relieved when we change the world for the better. Before Account Abstraction We were not satisfied with smart contracts and EOAs. We needed more. We needed them to learn from one another a
When ZK meets Medicine
What on Earth could bring such a collaboration? How could one combine the two? Being part of Zuzalu is an exciting and immersive experience in many manners, especially when it comes to widening our views. It was quite an honour to be invited to spend two months with some of the world's most remarkable experts in different fields. Every time I looked around, I found experts. ZKs, biology, ageing, longevity, network states, DeSci… you name it. This was a very fertile ground for making connecti
Optimising gas usage in Solidity
Lately, it became tricky to find truly efficient solutions for gas optimisation online. What happens is, either they are simply wrong assumptions, or they became obsolete in the meantime, or we need more context to fully understand the proposed solution. But, one thing is for sure - There is always some puzzle missing. The following examples are based on Branislav's lecture using the Tenderly gas profiler and simulations which are completely free - make sure to create a profile there and enjoy
WTH is Zero Knowledge Proof?
Zero-knowledge proof is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without revealing any additional information beyond the fact that the given statement is true. This magic is done by allowing the prover to create a mathematical proof that the statement in question is true, which the verifier can then check without the need to see any additional information. For those who have never seen ZKPs (and for those who have seen
My 🔑 Notes on Blockworks' Predictions for Crypto in 2023 - in 3 minutes
Crypto’s 2022 wrapped Compared to prior cycles, we started to see real use cases. ATM, there is a global financial crisis in the blockchain mostly due to translating TradFi into DeFi, and the lack of transparency. This is the first bear market in history where people have not thought that the industry is done. The positivity of technology has been acknowledged. The flight of talent into the industry is here to stay. 1st QRT is gonna be a wipeout due to seasonality, poor vortexes, and global
Creating light nodes using substrate-connect
I had the pleasure of joining the discussion about light nodes integrated into wallets hosted by Stefan Sopic from Parity Technologies. Many web3 folks are not quite aware that things are pretty centralised in our decentralised world. Decentralisation in reality MetaMask, behind the scenes, is using Infura infrastructure. Stefan made a solid point that the focal point of all the requests* MetaMask handles is in fact based on the East Coast, USA, through the same blockchain node provider. I
The most important blockchain development skill
Given my role, I often get the question “What is the most important thing to learn to make a proper transition from web2 to web3?” Indeed, no matter how important technologies are along the way because, of course, you can’t do without them, what sets a top-notch web3 developer apart is a complete change of mindset. Regardless of whether you are dealing with Solana, Polygon or Ethereum, you won’t go far without it. It is not only the ability to learn new things but also to UNLEARN previously ad
