Point Time Locked Contract (PTLC)
A Point Time Locked Contract (PTLC) is a Bitcoin transaction which locks bitcoin to a point on Bitcoin’s elliptic curve.
A Point Time Locked Contract (PTLC) is a Bitcoin transaction which locks bitcoin to a point on Bitcoin’s elliptic curve. The outputs created by this transaction type are also time locked, meaning they cannot be spent before a certain time, as denominated in UTC time or block height. PTLCs are similar to Hashed Time Locked Contracts (HTLCs), but offer privacy gains as well as fee savings.
For this reason, PTLCs may replace HTLCs as the driving contract behind the Lightning Network and other off-chain protocols. Point Time Locked Contracts will become most accessible after Schnorr signatures have been implemented on Bitcoin, which will occur when the Taproot upgrade is activated.
Point Time Locked Contract (PTLC) is a concept within the Lightning Network, Bitcoin's layer-2 scaling solution that enables fast, low-cost transactions. Onramp's glossary covers Point Time Locked Contract (PTLC) and related Lightning Network technology to help investors understand Bitcoin's expanding payment infrastructure.
Frequently Asked Questions
What is Point Time Locked Contract (PTLC)?
Point Time Locked Contract (PTLC) is a component or feature of the Lightning Network, which enables near-instant Bitcoin payments by creating off-chain payment channels between parties.
How does Point Time Locked Contract (PTLC) improve Bitcoin payments?
Point Time Locked Contract (PTLC) contributes to faster and cheaper Bitcoin transactions by enabling off-chain settlement. Lightning Network transactions typically complete in under a second with fees of fractions of a cent.
