first input is P2WPKH:

program : 0 0x14 0x8E3F94B8E7EEF5661AC7AFEC61FE3EF6CCE5398C
value : 4.504
privkey : FC17E76AC1311192D280E417C376E39F34AC3A5D1E031E86FFCF43FF6F5B446C

second input is P2WPV0:

program : 1 0x21 0x02C929B19F8DE22FF56302141BD6DC941779628371225C59214631397A3D3C837C

privkey : 7A31BE18DA5EC37BE3350B32F3A228880A4DE7C35CCD1E75A69B93AFB66B6E12

The outputs are valued at 5.5 for the first and 2.0 for the second output.
The fee used in the transaction is 0.01, and 0.006 of that sum are paid by the P2WPKV0 (second) input.

As a soft fork, older software will continue to operate without modification. Non-upgraded nodes, however, will consider <code>MSV0</code> and <code>P2WPKV0</code> programs as anyone-can-spend scripts.
