SegWit moves signature data out of the transaction's scriptSig into a separate witness field, which doesn't count toward the block size limit (with a weight-based limit instead). This increases effective block capacity, fixes transaction ma
SegWit was a pivotal Bitcoin upgrade — it enabled Lightning Network, reduced fees during congestion, and demonstrated that soft-fork upgrades could succeed. Its legacy includes the block-size debate that led to the Bitcoin Cash fork.

1. What Is SegWit
SegWit (Segregated Witness) is a Bitcoin protocol upgrade (2017) that separates transaction signatures (witness data) from the main transaction data, increasing block capacity and enabling second-layer solutions like Lightning.
2. How It Works
SegWit moves signature data out of the transaction's scriptSig into a separate witness field, which doesn't count toward the block size limit (with a weight-based limit instead). This increases effective block capacity, fixes transaction malleability (enabling Lightning channels), and introduced new address formats (Bech32, starting with bc1).
3. Why It Matters
SegWit was a pivotal Bitcoin upgrade — it enabled Lightning Network, reduced fees during congestion, and demonstrated that soft-fork upgrades could succeed. Its legacy includes the block-size debate that led to the Bitcoin Cash fork.
4. Key Facts
- Activated August 2017 via BIP 141 (soft fork)
- Introduced Bech32 addresses (bc1...)
- Weight-based block limit replaced size-based
- Enabled Lightning via transaction malleability fix
