Bitcoin Block Size Increase in Mid-Term is Possible

Bitcoin Block Size Increase in Mid-Term is Possible

On November 13 Blockstream chief executive Officer and HashCash inventor Adam Back, who stays as one of the few people mentioned within the original Bitcoin whitepaper launched by Satoshi Nakamoto, defined Bitcoin block size growth within the mid-term is an opportunity that has not been ruled out.

In reaction to a statement supplied by Jihan Wu, the co-founder of Bitmain, the three billion dollars Bitcoin mining equipment manufacturing organization, concerning the need of a block size growth to reduce Bitcoin Blockchain congestion, Adam Back said:

“Probably mid-term with enough testing yes. However, within the intervening time it would be great if people could prevent spamming. Thank you.”


As Adam Back defined, the Bitcoin core improvement group has not been essentially against on-chain Bitcoin scaling. In 2014, Adam Back mentioned that a sluggish block growth to 2MB, 4MB, and 8MB is a possible option within the mid-term, until second-layer payment channels are completely followed by the industry, wallet platforms, and exchanges. however, Bitcoin center and most people of the Bitcoin community remain sure that block size boom isn’t an extended-term scaling solution, in comparison to public viewpoints, due to there’s a restrict to which the block size of any Blockchain network which includes Bitcoin may be improved to.

One main cause Bitcoin block size growth isn’t a long-term scaling solution is due to if the block size increases in proportion to the growth of the Blockchain network’s user base, necessarily the block size will gain a point in which personal node operators are left out and transactions are proven by a centralized group of nodes. Such is the extent of centralization imposes risk to any Blockchain network apart from Bitcoin. As an example, if the block size of a Blockchain network is elevated to 10MB, to 50MB, and eventually to 100MB, it’ll create an environment in which person node operators are basically non-existent.

Andreas Antonopoulos said:

“If my block takes eleven mins to validate, then I’m off the Blockchain, which means fewer people can validate independently, this means that the system becomes centralized. With such an increases, fewer people can take part within the validation process, fewer people can take part in storing the information, and less people can take part in being independent actors. We go from a system this is decentralized to a system that progressively receives increasingly more centralized.”


Therefore, Bitcoin block size need to be planned in advance, go through rigorous testing, be cautiously thought out, and performed whilst actually important, throughout a period wherein the transaction expenses at the Bitcoin network become too high for the majority to settle a payment. these days the transaction expenses were considerably high, most of them being above one to two dollars, but the growth in the size of the Bitcoin mempool became induced by the migration of Bitcoin miners to the Bitcoin cash network. The instability in hashing power led hundreds of thousands of transactions left unconfirmed, ultimately growing the size of the Bitcoin mempool to over one hundred million bytes.

As miners go back to the Bitcoin network after the subsequent hard adjustment and more businesses, adopt segregated witness for nearly thirty-five percent discount in fees in line with Bitcoin hardware wallet improvement company Ledger fees need to be possible within the short-term. Within the mid-term, if transaction expenses become too high, as Adam Back noted, block size increase is actually a possibility with rigorous and thorough testing.
