SegWit is related to Bitcoin and its core rules, so its strengths and weaknesses will differ relying on who’s observing it.
SegWit’s capability to offer blocks extra weight, or transaction density, depends on the concept that some blockchain information might be stored off the unique chain, which is as an alternative used as a kind of reference or index. Some consider that offloading information from the blockchain is already a failure, because it’s like admitting that blockchain alone can’t operate.
From this angle, SegWit itself is a weak spot infecting Bitcoin, and that’s why quite than implement SegWit, a chunk of the neighborhood onerous forked into a brand new blockchain referred to as Bitcoin Cash in 2017.
Bitcoin Money is basically legacy Bitcoin earlier than SegWit, and its scaling technique is solely to extend the block measurement and hold all information on-chain. It is a decentralization technique reverse that of the Bitcoin Core group, which sees SegWit as the primary stack atop a multilayered blockchain.
