Thank you for purchasing Grokking Bitcoin. If you find errors not listed below, please report them in the LiveBook errata thread. We'll update this list as necessary. Thank you!


Table of contents

The section "Recap of payment types" is missing in the table of contents for chapter 10. It should be right before the "Block limits" section.

Front matter, page xx, preface

The text "... trying to find a my place in the Bitcoin community ..." in the third paragraph should read "... trying to find a place in the Bitcoin community ..."

Chapter 4, page 87

In the list of wallet duties, "Back up private keys" should be all italics. The trailing s is not.

Chapter 4, page 111

The header "Public key multiplication" should be one level down under the "Public key math" header. The other headers under "Public key math" should remain, so that "Public key multiplication" is on the same level as for example "Why is this secure?".

Chapter 6, page 189

In the section "Verifying the partial merkle tree," the reference to figure 2.28 is wrong. It should reference figure 6.28.

Chapter 9, page 320

In the paragraph directly preceeding figure 9.15, the figure reference "Figure 9.14" is wrong. It should say "Figure 9.15."

Chapter 10, page 350

The sidebar titled "Nonstandard transactions" doesn't use curly apostrophes '’'.

Chapter 10, page 355

Last paragraph of section "Spending the p2wsh transaction" ends with a double period, "..". It should end with single period ".".

Chapter 10, page 362

The figure after Figure 10.34, is labeled as "Figure 10.3," when it should be labeled as "Figure 10.35."

Chapter 11, page 397

The third paragraph, which discusses the risks involved in BIP148, says "It could cause a chain split if a majority of the hash rate didn't signal for segwit." This is misleading. Instead it should say "It will cause a chain split if a miner publishes a non-segwit-signalling block." Thanks to Sjors Provoost for pointing this out.

Chapter 11, page 399

The bold paragraph contains the word "follow" in italic but not bold. The word should be both italic and bold.

Appendix A, page 418

The paragraph right after the bullet list contains "I've" and "don't" with straight apostrophes. They should use curly apostrophe, as in "I’ve" and "don’t"

The paragraph right after the bullet list ends with a colon character; it should end with a period.

Appendix B, page 425, answer 3.10

The second instance of "can't" uses straight apostrophe. It should use curly apostrophe as in "can’t".

Appendix B, page 426, answer 4.9

The fifth numbered item uses fixed width font for the number "5." It should use the same style as the previous four items.

Appendix B, page 436, answers 9.9 and 9.10

The last sentence, "The node will thus never know ..." of answer 9.10 is misplaced. It should be the last sentence of answer 9.9.

Appendix B, page 437, answer 10.6

The word "can't" uses straight apostrophe. It should use curly apostrophe as in "can’t".

Appendix B, page 438, answer 10.9

The typesetting of PKHY should be all monospace, but the subscript is not.
