About Segregated Witness (SegWit)
Binance announced adding SegWit support, aiming to improve Bitcoin transaction efficiency. And it will allow its users to withdraw or send their Bitcoin holdings to SegWit (bech32) addresses.
The term SegWit stands for “Segregated Witness”. SegWit is an improvement over the current bitcoin blockchain which reduces the size needed to store transactions in a block and it is implemented as a soft fork on the Bitcoin network. By separating the transaction signatures from bitcoin transactions, it allows more transactions to fit within one block. This will result in smooth and rapid Bitcoin transactions.

SegWit or nested SegWit addresses(P2SH) : These are multi-purpose addresses that support both non-SegWit and SegWit transactions. These addresses start with “3”.
Native Segwit(bech32): The native Segwit address starts with “bc1”. These addresses include only lower case letters for better readability.
