Bitcoin segwit support

However, as implemented, segwit does not make this any easier: with or without segwit, a future soft-fork enabling compact fraud proofs and the benefits they bring, will need to include its own commitment (eg, in the coinbase transaction), rather than being able to extend the commitment data used by segwit.The modified hash only applies to signature operations initiated from witness data, so signature operations from the base block will continue to require lower limits.Developer makes stupid Android app so you can turn your phone into an iPhone X.Samsung updates official Note8 specs to include 4K 60FPS recording.Finding the most profitable set of transactions to include in a block given a single limit is an instance of the knapsack problem, which can be easily solved almost perfectly with a simple greedy algorithm.Reduced UTXO growth will benefit miners, businesses, and users who run full nodes, which in turn helps maintain the current security of the Bitcoin network as more users enter the system.

New nodes, which understand the full block with witness data, are therefore free to replace this limit with a new one, allowing for larger block sizes.

SegWit will bring many benefits to the Bitcoin network, but more importantly, lays the ground work for the Lightning Network (LN) which will bring faster and cheaper transactions, and better scalability.Doing that without also limiting transaction sizes allows Bitcoin to continue to support payments that go to or come from large groups, such as payments of mining rewards or crowdfunding services.
