Because of the recent Mempool congestion due to BRC20 some discussions of past crossed my mind. Bitcoin Scalability Problem is not new. Block Size Limit Controversy was a byproduct of this. This gave us multiple BIPs (Bitcoin Improvement Proposal) by multiple experts. Below is a consolidated list of those all...

• BIP 100 by Jeff Garzik, Tom Harding & Dagur Valberg Johannsson
• BIP 101 by Gavin Andresen
• BIP 102 by Jeff Garzik
• BIP 103 by Pieter Wuille
• BIP 104 by t.khan
• BIP 105 by BtcDrak
• BIP 106 by Upal Chakraborty
• BIP 107 by Washington Y. Sanchez
• BIP 109 by Gavin Andresen

Out of all these, I have always voiced in favor of BIP 106 on BitcoinTalk. Proposal 2 : Depending on previous block size calculation and previous Tx fee collected by miners has always seemed most practical & effective to me.

Now, as almost 8 years have passed and the scaling issue is still daunting us, what do you think about this proposal?
