how is dash going to compete with segwit for insta~send.... ?
Segwit is only creating an extented block (the segrated witness) to remove data (transactions signatures) from the orignal block to free some space. It has nothing to do with the speed of a transaction. Dash Instasend use the masternode network to validate 6 confirmations presto (in a matter of seconds) based on a quorum.
Frankly, segwit is a weird tweak to increase the blockchain size without increasing the 1MB minable blocksize.
sorry my bad I mean
the lightning network....
will that hollow out a lot of the utility of dash?
Why would it? Lightning Network is a fudge that's only going to defer the scaling problem temporarily by bastardising the blockchain product into an off-chain settlement layer.. Technical and economic disadvantages of this aside, f you have to send transactions off the blockchain you're no longer using blockchain.
Dash InstantSend is fully on-chain double-spend-proofed instant confirmations. With Evolution, Dash will be able to scale on-chain to mass-market level transaction capacity, with instant confirmations available for TX fees that will be even tinier than they are now.
