Project spotlight

  • 01:05:35 The Bitcoin Time Capsule
    • Create a timelocked wallet on BTCapsule, and when the time comes, your bitcoin will be available to whomever you choose.

    • The sender wallet contains a raw transaction that is timelocked to 500,000,001 at the transaction level and allows you, the original holder, to redeem your Bitcoin at any time.
    • The receiver wallet contains a raw transaction that is locked at whatever date you choose, which is then converted to a unix timestamp.
