In addition, it seems we can do even better in terms of performance by sticking with 2–4–8 but allowing non-fully-validating nodes to ignore approximately half of this data. This would be a big improvement that would alleviate the pressure that we’ll be putting nodes by scaling the block size. The improvement is being called Segregated Witness and involves separating signatures out from the main block and putting them into a Merkle tree that only fully-validating nodes have to see.

So, with this change full node will now be called fully-validating nodes?
Are the non-fully-validating nodes like SPV wallets?
