Precompile is like a cheese, optimized, does 1 thing and ready to use Precompiles are predefined smart contracts that have a special address and provide specific functionality which is not executed at the EVM bytecode level but natively by the client. Like this guy, a precompile does only 1 thing really good They are primarily used to add specific functions that would be computationally expensive if executed in the EVM bytecode. They also serve a purpose to facilitate the interaction between a parent cha...

You run `cargo build` on a large Rust codebase, something like compiling a blockchain node from source and saw your system freeze or face an out-of-memory error. I faced this issue when building Mina Protocol’s rust node on my 16GB machine and got me thinking what is happening in my machine during Rust compilation and can it be optimized for a successful build? Frozen machine…reaction on point This happens due to compiled languages like Rust can ask for substantial system resources during the build proce...

I have been reading about rollup specs that help Ethereum scale. Always being curious about how do they execute transactions, and how does the finalization work with them, what about fees and all. Rollups such as Optimism and Arbitrum implement their own node service which includes some stuff like a sequencer, execution engine to execute transactions, and more. Here I am just going to give a high level study about workings of execution engines in rollups that I have understood after reading Optimism roll...
