My Vision, for SegWit And Lightning Networks On Litecoin
If Bob is trustworthy, he will reissue the payment to Charlie; but if he isnt, he can simply keep those bitcoins for himself. For example: 50*sigops 4*basedata 1*witnessdata 10M This lets miners easily and accurately fill blocks while maximising fee income, and that will benefit users by allowing them to more reliably calculate the appropriate fee needed for their transaction to be mined. I heard P2SH took almost two years to become widely deployed. This includes the node operator, if they use it to protect their wallet, as well as lightweight clients who get their data from the node.
Here's what you need to know about
To maintain the decentralised, trustless nature of Bitcoin, it is important to allow those who cannot afford to validate the entire blockchain to at least be able to cheaply validate as much of it as they can afford. But in a system with third-party malleability, wallets must implement extra code to be able to deal with changed txids.

Other lines of code would need to be changed to prevent these problems. Block size increase up to. In essence, doubling the size of a transaction can double both the number of signature operations, and the amount of data that has to be hashed for each of those signatures to be verified.
Bitcoin, core : Segregated Witness, benefits
This means that a hardware wallet can simply be given the transaction hash, index, and value (and told what public key was used and can safely sign the spending transaction, no matter how large or complicated the transaction being spent was. Multisig payments currently use P2SH which is secured by the 160-bit hash160 algorithm (ripemd of SHA256). Weak blocks and iblts can both be deployed as network-only enhancements (no soft or hard fork required) which means that there will probably only be a short time from when testing is completed to when their benefits are available to all upgraded nodes. Capacity increases for the Bitcoin system, written by Gregory Maxwell and published to the bitcoin-dev mailing list. What is the roadmap?

The Segregated Witness soft-fork (segwit) includes a wide range of features, many of which are highly technical. When a hardware wallet signs a transaction, it can easily verify the total amount being spent, but can only safely determine the fee by having a full copy of all the input transactions being spent, and must hash each of those to ensure. Segregated witness therefore takes advantage of this opportunity to raise the block size limit to nearly 4 MB, and adds a new cost limit to ensure blocks remain balanced in their resource use (this effectively results in an effective limit closer.6.

Currently there are two consensus-enforced limits on blocksize: the block can be no larger than 1MB and, independently, there can be no more than 20,000 signature checks performed across the transactions in the block.
