In the bitcoin scripting language, how can I access other outputs of the transaction? Or how else can I limit...












1















Is there any way to add an opcode to a UTXO that prevents how the coins are spent?



For example, in order to to spend the output, a person must send X number of bitcoin to Y address within the accompanying transaction.






script op-return

          There is no way to enforce a rule regarding the nature of an output when an input is spent. You will have to enforce this off chain in some manner, perhaps through multisig schemes where one key is held by a rule engine that will only sign the tx if your requirements are met.

          • No, that is a bounty people can claim if they are able to produce two values that hash to the same hash for some hash function in the script. For example, the bounty for sha1 was claimed after Google released a collision attack

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{

It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean?
