Because there is an ordinary ratio of signature data to non-signature data in transactions (which holds unless someone is cramming non-cryptocurrency data into the blockchain) there is a greatly diminishing incentive for UTXO reduction given a discount past that ratio, but an increasing exposure to the extra space being abused.
With the introduction of the Segwit «feature» by the Segwit Core developers, a new transaction type was created that removes the digital signatures from the transaction and places them in a separate data structure, where they are only visible to users running certain versions of software.
Dr. Pieter Wuille suggested that the digital signatures of the transactions, which comprise 65 % of their size, be segregated from the transaction's data — thus the phrase «segregated witness».
Segregated Witness (SegWit), the update implemented to the BTC chain on August 1, instead creates more space within the 1 MB block size by removing part of the signature data from each transaction.
After August 1, bitcoin became SegWit — segregated witness — which means that part of the signature data of each transaction is stored separately.
«SegWit» is an abbreviation for «segregated witness», which is the process whereby a blockchain's block size limit is increased by removing signature data from transactions.
SegWit essentially involves pruning some of the signature data from a transaction to make the transaction smaller, and therefore fit more transactions on the blockchain.
But Nguyen said, «SegWit assumes that signature data is only needed when transactions are being validated, and can thereafter be discarded as unimportant.»
They just need the block headers of all blocks (a sort of index of blocks without all transaction data) and the aforementioned dummy output signatures: both relatively compact data - sets.
for example, the simplest possible one - input, one - output segregated witness transaction would be about 90 bytes of transaction data plus 80 or so bytes of signature — only those 90 bytes need to squeeze into the one megabyte block, instead of 170 bytes.
«By separating and discarding signature data, SegWit would make the legal proof and authentication of electronic contracts and transactions significantly more difficult,» Nguyen wrote.
Among these proposals is Bitcoin Core's Segregated Witness, or SegWit, whose main goal is to send signature data or witnesses off - chain and onto second layers like the Lightning Network or sidechains to fit more transactions into the current 1 MB block size.
SegWit provides on - chain scaling by separating the base transaction data from the signature data, which reduces the data transmitted in a transaction and in doing so allows higher concurrent transaction volume on the Bitcoin blockchain.
With Segregated Witness, all signature data is moved to a separate part of the transaction: the witness, which is not embedded in the «old» Bitcoin protocol.
While full nodes typically store all transaction data for all of Bitcoin's history, signatures are reasonably considered expendable after a certain amount of time has passed.
Of course, ridding the blockchain of older signatures is not a purist's ideal, as he might want to verify old transaction data regardless.
Today, a standard bitcoin transaction records both transaction and signature data together, with the signatures accounting for approximately 60 % of the data size.
The Bitcoin Core development team's proposed scaling solution, called Segregated Witness (SegWit), would separate signature data («witnesses») from transaction data, and a new solution, Segwit2x, builds upon that proposal.
