Vout[n]. prevout), we say that the i-th input of tx spends the n-th output of TxSource. COutPoint holds a hash code of type uint256, which is the hash of the source-transaction. We cover this class next. 1. h An uint256 holds a 256-bit hash code. It contains an unsigned int array of length 256/32=8 to hold the hash code. Another similar data structure uint160, defined in the same header file, holds a 160-bit hash code. It has an unsigned int array of length 160/32=5 to hold the hash code. These two classes share the same base class base_uint.

29: }; 30: class uint256 : public base_uint256 31: { 32: //...... 33: }; base_uint overloads many operators. These operator overload functions are not shown in here. They all work on the inner data storage array pn to implement their functions. One thing worth mentioning is that the three serialization member functions of base_uint (GetSerializeSize(), Serialize(), and Unserialize()) follow the same naming convention described in Chapter Serialization. So class base_uint and its derived classes can be integrated into the serialization/de-serialization chain explained in Chapter Serialization.
