Grin block limit is 1.5MB Grin supports up to 10 transactions per second. Given the great controversy surrounding bitcoin's history, is there any possibility of increasing this in the future?

851 txs per block or 851/60=14.2 txs per second.

/// Total maximum block weight. At current sizes, this means a maximum

/// theoretical size of:

/// * `(674 + 33 + 1) * (40_000 / 21) = 1_348_571` for a block with only outputs

/// * `(1 + 8 + 8 + 33 + 64) * (40_000 / 3) = 1_520_000` for a block with only kernels

/// * `(1 + 33) * 40_000 = 1_360_000` for a block with only inputs

///

/// Regardless of the relative numbers of inputs/outputs/kernels in a block the maximum

/// block size is around 1.5MB

/// For a block full of "average" txs (2 inputs, 2 outputs, 1 kernel) we have -

/// `(1 * 2) + (21 * 2) + (3 * 1) = 47` (weight per tx)

/// `40_000 / 47 = 851` (txs per block)

///

pub const MAX_BLOCK_WEIGHT: u64 = 40_000;

When will Grin get a Wikipedia page?

When will Grin get a Wikipedia page? I could easily write one with Chat GPT, but the problem is that I am IP-blocked from Wikipedia. I also think it would be necessary to provide some "reliable sources". If you have sufficient knowledge of Grin and can provide any scientific paper or news paper article about Grin, I really encourage you to start it. I provide you the link: https://en.wikipedia.org/wiki/Grin_(cryptocurrency)

Selling 4 iPollo G1 Minis

I have four iPollo G1 Mini mining rigs for GRIN I am selling. I used them to mine at my work office since we don’t pay for electricity there, and my lease is ending soon. I’ve mined with them for 3 years without any issues. They’re all in good shape and I’ll throw in the ethernet cables as well. I’ll do $500 for the set

Edit: I actually have 5 rigs. Will do 5 for $500

Is it possible to cancel withdrawal from tradeogre ?

I was running GUI wallet on PC connected to same screen as another PC with opened exchange.

I accidentally pressed enter on web interface of exchange after generating slatepack. GUI wallet was not showing me button to generate response (maybe cause pc with wallet was running with 1024*768 resolution) I I tried to press "invisible button" while keyboard was not connected to "wallet pc".

Any was to cancel / restart withdrawal ?

BEWARE fake Grin BSC token on MEXC

At least they have changed the logo away from this projects, but MEXC recently listed a BSC token called Grin that is a sham and acting like it's some privacy coin on Twitter.

STAY AWAY!
