P2PKH output script: OP_EQUAL vs. OP_EQUALVERIFY

[RequestPrivacy]

Hello,

I'm going through "Mastering Bitcoin 3th ed." and on page 65 the following output script is printed as an explanation:

bitcoinbook/ch04_keys.adoc

Line 576 in 6d1c26e

OP_DUP OP_HASH160 <Bob's commitment> OP_EQUAL OP_CHECKSIG

4 lines below input and output script are printed together as follows

bitcoinbook/ch04_keys.adoc

Line 588 in 6d1c26e

<sig> <pubkey> OP_DUP OP_HASH160 <commitment> OP_EQUALVERIFY OP_CHECKSIG

Notice the use of OP_EQUAL in the first vs. OP_EQUALVERIFY in the second.

Is this an error as other mentions of such an output script is also with OP_EQUALVERIFY e.g. here:

bitcoinbook/ch07_authorization-authentication.adoc

Line 271 in 6d1c26e

OP_DUP OP_HASH160 <Key Hash> OP_EQUALVERIFY OP_CHECKSIG

Hi @RequestPrivacy . It does indeed look like the first script should use OP_EQUALVERIFY. Good catch, thanks!

Thank you for the confirmation and work on the fantastic book!
