Recently, I had to find fixes to an ABI library, and it was an eye-opening experience. As I tackled the issues, I learned some new insights on ABI encoding and wanted to share my notes here. Specifically: - Function signatures and how they're calculated - Encoding static and dynamic types - Useful methods provided by Solidity's abi variable - Packed encoding with abi.encodePacked Read more here:  https://lnkd.in/gvFsQxWr #Solidity #Blockchain #Ethereum #SmartContracts #Programming #TechInsights

Interesting fact about blockchain Blockchain was originally conceptualized in 1991 by Stuart Haber and W. Scott Stornetta as a way to timestamp digital documents to prevent backdating or tampering. However, it wasn't until 2008 that the concept was incorporated into the design of Bitcoin by an unknown person or group using the pseudonym Satoshi Nakamoto. This innovation laid the foundation for the broader application of blockchain technology beyond cryptocurrencies.

#Yesterday, #Solidity announced the release of the Solidity Compiler v0.8.23. This newest version of the compiler is meant to be a pure bugfix release that includes the fix for an important bug of low severity. Based on investigations, #Solidity team did not foresee real-world instances of the bug being used as an exploit or an attack vector and thus, they assess its overall severity as low. This version also introduces a small change to optimizer settings to make them more intuitive. Since v0.8.21, disabling the optimizer.details.yul setting no longer prevents the compiler from running the UnusedPruner step, which they consider an essential part of the internal mechanism for preventing stack issues. The step can still be disabled - by explicitly supplying an empty optimization sequence - but this required nominally enabling the Yul optimizer, which sometimes led to users enabling the optimizer as a whole and inadvertently including extra optimizations. Now it is possible to use an empty sequence independently of other settings. Please read the whole story: https://lnkd.in/gw_edUKj #blockchain #solidity #bugfixing #newversion

During the past few weeks, I tried to document multiple polynomial commitment schemes in short. What are polynomial commitments? To build an efficient SNARK, you combine a polynomial commitment scheme with a polynomial interactive oracle proof. I covered the most widely used so far: - KZG - https://lnkd.in/g6cWnnqy - Bulletproofs - https://lnkd.in/gKWMKFPx - FRI - https://lnkd.in/gM8Kpuy8 Linear PCP ( used in Groth16 scheduled for tomorrow ). #zeroknowledge #cryptography

An interesting fact about blockchain Blockchain is that it was originally conceptualized in 1991 by Stuart Haber and W. Scott Stornetta to timestamp digital documents to prevent backdating. However, it was fully realized and implemented as a core component of the cryptocurrency Bitcoin in 2009 by the mysterious person or group known as Satoshi Nakamoto.
