If correctly maintained, all prior exit transactions will be invalidated and not spent on the network...\"\r\n\r\n\u25a1BSV's scalability and security\r\n\u3161BSV is implemented to directly handle unlimited massive transactions on-chain without complex off-chain solutions like the Lightning Network (LN), by effectively removing the block size limit in accordance with the goals of the original Bitcoin Whitepaper. In terms of security, it utilizes the SPV (Simplified Payment Verification) mechanism specified in the Whitepaper, instead of LN's continuous monitoring system (Watchtower). \r\nSPV allows light clients to cryptographically verify that a transaction is included in the longest Proof-of-Work chain using block headers and Merkle Proofs, in a simple and trust-minimized manner, without needing to download the entire blockchain.",
