stellar-core VS solana

There is an active scam proliferating using a fake "Stellar" site. Make sure that you are only accessing the official Stellar website, which is https://www.stellar.org/, type the URL into your browser address bar. Always check the full URL before entering any personal information — make sure, for example, someone did not replace a lowercase "L" with an uppercase "i"! or that there are no additional letters following ".org/" in the domain address such as "stellar.org.jp/".

"Stellar Core": This software was created by the Stellar Development Foundation (SDF). Anyone can use it to run their own blockchain https://github.com/stellar/stellar-core

it's a code fork of https://github.com/stellar/stellar-core with very minor modifications as far as has been ascertained.

Stellar network

The coin is designed to benefit cannabis communities and businesses (eco-friendly, fast, and very low transactions fees via Stellar Network). You can currently buy cannabis products with the coin at Everlasting Extracts and 2 other businesses.

I would not call the "survey of 2,079 respondents" by Stellar Development Foundation [0] "woefully-lacking-of-legit-citations".

Pi is running their own chain using the stellar blockchain software. It's open source so anyone can do this. https://github.com/stellar/stellar-core

Solana (9700 GitHub Stars) https://github.com/solana-labs/solana

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.

Solana

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.
