Over the past month development has been progressing to bring SegWit (Segregated Witness) support to the Stratis blockchain, resulting in upgrades to the consensus, mempool and wallet features.
SegWit is an update to the transaction scripting layer that, among other things, increases the effective maximum transaction throughput.
The latest milestone to be achieved is the successful sending of SegWit transactions on the Stratis TestNet. You can find more detail below regarding the SegWit transactions in question, shown in an experimental version of the Stratis Core wallet:

Transaction 1

Transaction 2

Transaction 1 shown above, spends a legacy P2PKH (i.e. pay-to-pubkey-hash) input, and sends it to a native SegWit P2WPKH bech32 address (i.e. pay-to-witness-pubkey-hash).

Transaction 2 spends a native SegWit input, sending it to a SegWit address. This is therefore a fully native SegWit transaction with no legacy inputs or outputs.

These are the first encouraging steps to bringing SegWit support to the Stratis Mainchain, further development will continue, focusing on bringing SegWit support to our wallet implementations. The SegWit implementation will then undergo our full end-to-end testing procedure within our Stratis Coherence environment.
