Be warned that my test program will likely take all your Bitcoins cause your wife to leave you shoot your dog though your resulting country music career may be. To avoid this, you can prefix all data with the appropriate push operation. For the verification of each signature, the amount of data hashing is proportional to the size of the transaction. Segwit improves the situation here by allowing a future soft fork to extend the witness structure to include commitment data which will allow lightweightSPV) clients to enforce consensus rules such such as the number of bitcoins introduced in a block, the size of a block the number of sigops used in a.Grâce à segwit un futur soft fork pourra étendre la structure de witness pour y inclure des données de commitment la taille d un bloc, ce qui permettra à des clients légersSPV) de vérifier le respect des règles de consensus telles que le nombre de bitcoins créés dans un bloc et le nombre de sigops.
