# Segregated Witness (SegWit) 1. A process where the [[Transaction(s)|transaction]] signatures are separated from [[Bitcoin (blockchain)]] transactions. Allowing more transactions to fit within one [[Block(s)|block]]. 3. A proposed change to Bitcoin's [[Blockchain|blockchain]] that would increase the block size limit from 1MB to 2MB for faster transactions. The implementation would be a [[Fork|fork]] (see above). 4. The process where the [[Block Size|block size]] limit on a [[Blockchain|blockchain]] is increased by removing digital signature data and moving it to the end of a [[Transaction(s)|transaction]] to free up capacity. Transactions are essentially split (or 'segregated'), into two segments: the original data segment and the [[Signature|signature]] (or 'witness') segment. SegWit removes the malleability risk from the main blockchain and checks it before a transaction becomes a part of the blockchain and has all its information added to the blockchain, making the information irreversible. SegWit makes it possible to track [[bitcoin (BTC)]] spending in an easy way, which is looking transactions up using their [[Transaction ID (TXID)]]. 5. Segregated Witness, or SegWit in short, is a [[Soft Fork]] solution that addresses the [[Scalability|scalability]] issue as [[Transaction(s)|transactions]] on the [[Bitcoin (blockchain)]] network increases over time. SegWit allows the [[Signature|signature]] part of bitcoin transactions to be separate from the transfer, resulting in a smaller transaction size. This means that more transactions could be fitted into a [[Block(s)|block]] regardless of the block size. SegWit also introduces some security improvements, such as fixing the transaction malleability problem where transaction IDs could be modified. This would make it easier for [[Wallet|wallet]] owners to track their spent bitcoin and prevent follow-up transactions from becoming invalid due to an earlier payment or [[Transaction ID (TXID)|transaction ID]] getting modified. With this malleability issue resolved, the [[Lightning Network|Lightning Network]] will also be less complicated to implement as there will now be more efficient use of space on the blockchain. See also, Lightning Network. 6. Segmented Witness (or SegWit) is a soft fork that happened with the Bitcoin [[Blockchain|blockchain]]. It solved congestion on the network by increasing the blockchain’s [[Block Size|block size]] limit and splitting blocks of data in two. It separated out the unlocking signature with the scripts that send and receive data with the transactional data. This allows the network to process more [[Transactions Per second (TPS)|transactions per second]]. Users don’t have to wait as long for [[bitcoin (BTC)]] [[Transaction(s)|transactions]].
