Learning Steps

1. Generate Script

Select a script type and generate a Bitcoin Script with address and private keys.

  • Multisig for shared custody
  • Timelock for time-based spending
  • Escrow for dispute resolution
  • Hash lock for atomic swaps

2. Fund Address

Send testnet coins to your generated address using a testnet faucet.

Script Types Reference

Multisig

OP_2 <pubkey1> <pubkey2> OP_2 OP_CHECKMULTISIG

Requires 2 signatures from 2 public keys. Used for shared custody and security.

Timelock

<locktime> OP_CHECKLOCKTIMEVERIFY OP_DROP <pubkey> OP_CHECKSIG

Funds locked until specified time. Used for time-based releases and escrow.

Escrow

OP_2 <buyer> <seller> <arbitrator> OP_3 OP_CHECKMULTISIG

2-of-3 multisig for dispute resolution. Any 2 parties can spend.

Hash Lock

OP_SHA256 <hash> OP_EQUALVERIFY <pubkey> OP_CHECKSIG

Requires knowledge of secret (preimage). Used for atomic swaps and Lightning Network.

SegWit

OP_0 <witness_program>

Witness data separated from transaction data. More efficient and enables Lightning Network.

Miniscript

or_b(pk(Alice), and_b(pk(Bob), pk(Charlie)))

Composable spending conditions. Alice OR (Bob AND Charlie) can spend.
