Read it on Github with syntax highlighting. In Trustless-Bridging Ethereum (EVM) Blockchains — Part 1: Basics you saw that we have the tools to prove any momentary state change that happened on chain A, on another chain B, assuming that chain B has access to trustworthy chain A block hashes. …

Read it on Github with syntax highlighting. With the emerging proposals for integrating the EVM in Ethereum 2.0 ( https://ethresear.ch/t/executable-beacon-chain/8271), this EVM to EVM trustless two-directional bridge series comes at just the right moment. It can bridge Ethereum 1 to Ethereum 2. And the other way around. A Symmetrical Light Client A Light Client…

Read it on GitHub: https://github.com/moral-upgrade-license/mul The Last Flinch of a Dying Demon There is an artificially induced financial stability in the world, which obscures the actual value of our work. If we are part of a guild — e.g. programmers, we expect our salary to be in a certain range, regardless of what we do. And these…

Read on Github. Environment For illustrating our journey, we will use the Yul language. Yul compiles to both WebAssembly and EVM bytecode. If you want to run the examples, it can be done with https://remix.ethereum.org: choose Yul as the compiled language, use the raw calldata input, check the return value using…

Imagine a space where you can freely explore a data set along several spatial indexes, such as in the following scene from “The Matrix”: Types. Lots of subtype polymorphism. Neo said “Guns. Lots of guns”. In reality, he would be in a logistics bottleneck: too many options and too…
