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

          How to label and detect the document text images

          Image
          1 $begingroup$ This is what I mean as document text image: I want to label the texts in image as separate blocks and my model should detect these labels as classes. NOTE: This is how the end result should be like: The labels like Block 1, Block 2, Block 3,.. should be Logo, Title, Date,.. Others, etc. Work done: First approach : I tried to implement this method via Object Detection, it didn't work. It didn't even detect any text. Second approach : Then I tried it using PixelLink. As this model is build for scene text detection, it detected each and every text in the image. But this method can detect multiple lines of text if the threshold values are increased. But I have no idea how do I add labels to the text blocks. PIXEL_CLS_WEIGHT_all_ones = 'PIXEL_CLS_WEIGHT_all_ones' PIXEL_C...
