I'v noticed that the current version of transaction in monero is now:
vin, vout, extra, rct_signatures etc.
My question is - when I run monero in testnet environment on my computer, the transaction include 'signature' field instead of the 'rct_sigantures' filed, and I'v try to figure out why is that.
From the context of the code I understood that this difference caused by the 'version' field, but I don't understand when 'version' is changed, and if I can use the rct_signatures field from the start (height 0)



Thank you!!!

          RingCT transactions are only activated at Monero version "4".



          Take a look at testnet_hard_forks in blockchain.cpp, and you'll see that version 4 is configured to activate at block height 801219, and therefore you won't see rct_signatures until that block height.

This Kransekake is a traditional Scandinavian baker's confection. Confectionery is the art of making confections , which are food items that are rich in sugar and carbohydrates. Exact definitions are difficult. [1] In general, though, confectionery is divided into two broad and somewhat overlapping categories, bakers' confections and sugar confections. [2] Bakers' confectionery, also called flour confections , includes principally sweet pastries, cakes, and similar baked goods. Sugar confectionery includes candies ( sweets in British English), candied nuts, chocolates, chewing gum, bubble gum, pastillage, and other confections that are made primarily of sugar. In some cases, chocolate confections (confections made of chocolate) are treated as a separate category, as are sugar-free versions of ...
