can someone tell in which release was RCTTypeBulletproof2 introduced? It seems it was Beryllium Bullet getmonero.org/2018/10/11/monero-0.13.0-released.html

there is RCTTypeBulleproof and RCTTypeBulleproof2, the former being deprecated by the later. AFAIK, RCTTypeBulleproof2 is the default transaction in Monero, right? I'd like to know since when

I was looking at the official repo and it seems RCTTypeBulletproof2 code was introduced in 2019, therefore I was wrong about it being included in the Beryllium Bullet

Lyza thank you very much for the answer. But, after searching the software releases in github, it seems like RCTTypeBulletproof2 was introduced in v14 github.com/monero-project/monero/releases/tag/v0.14.0.0 and that was some months after Bulletproof2 was introduced in the source code. Can someone confirm this please? thanks in advance

I'm not a dev but I think you're right -- "New slightly more efficient RingCT format" is listed in the overview

I was thinking you were referring to bulletproof plus

<r​ucknium:monero.social> The get_fee_estimate RPC call suggests a "quantization mask": all transactions should round their total fees up to 10,000 piconeros of precision. I know that this suggestion is not a blockchain consensus rule since I've found a few transactions that do not follow it. Is it a node transaction relay rule?

I don't think it is.

<r​ucknium:monero.social> Thanks. I only suspected a tx relay rule since so few transactions don't follow the rule. About 0.01% since the August 2022 hard fork. I am seeing about 5-10% transactions don't pay one of the "suggested" four tiers of XMR per byte. So even those nonstandard txs are following the quantization mask.

In case anyone's curious, I made a demo impl of Monero's mining and difficulty adjustment in Rust: github.com/darkrenaissance/darkfi/b…ter/script/research/pow/src/main.rs

Thought it might be nice to share :)
