EIP Core standards: Changes to Solana’s core code go through “feature gates” in the Solana repo. Yes, it’s much less organized than the EIP pages you are used to, and a headache to understand or keep up with. A cost of the speed of development, I’m told.

I visited the project on github (https://github.com/solana-labs/solana), and tried to get an overview of the ~800 open issues and ~100 open PRs.

With the introduction of new and advanced blockchain platforms in the Web 3.0 scene, the narrative around Ethereum has slowly shifted towards its younger “Ethereum Alternatives”. Solana, Avalanche, and MultiversX (former Elrond) are some of the crypto blockchains that are given this terminology, as they share similar features but are comparatively cheaper and better than Ethereum.

I understand this initiative is connected with Solana network [1] in some way?

They do, actually: https://github.com/solana-labs/solana/security/policy

Not sure I understand your question, but if you want the source code you can find it on github (https://github.com/solana-labs/solana)

Some topics that may be discussed in the next call include @ShinobiSystems Timely Vote Credits proposal (https://github.com/solana-labs/solana/blob/master/docs/src/proposals/timely-vote-credits.md), @elusivprivacy new built-in cryptographic operations to accelerate ZK verification (for privacy tech), and feature activation coordination standards.

I am trying to run a local cluster for the example hello wold program on GitHub but I keep running into these pop-up errors when I run the "solana-test-validator" command and I'm not sure why. For context, I am on a machine running Windows 11, running cmd prompt in administrative mode, and I have tried re-installing the Solana CLI tool but am still seeing these errors.

If we use the Hello World program provided by Solana Labs as reference, that program increments a counter every time a user interacts with the program:

The Solana helloworld example client is written in TypeScript. I found it hard to read because its extensive use of global state. To try and help future users and to learn a little about it myself I made an implementation of the example client in Rust which I find to be slightly more readable.

In this article, we'll walk through the process of sending a custom instruction to a solana on-chain program. We'll modify the solana example helloworld to take two instructions, SayHello and SayGoodbye.

Solana has a nice hello-world example that shows us how to build a Rust program on Solana from scratch and interact with it using a typescript SDK.
