In specific implementation, a power utilization user inquires own power utilization record and transaction conditions on a system and calls an intelligent contract to conduct power purchase transaction and inquiry operation. The intelligent contract date approves or rejects the electricity purchasing application of the user according to the current user state of electricity utilization. All the electricity purchasing records of the users are generated in a transaction mode, and power grid workers input the electricity purchasing records, historical electricity consumption and the like of the electricity utilization users in the system and call a preset intelligent contract to evaluate the electricity utilization conditions of the users. All evaluation records of the power grid staff to the electricity utilization users are generated in a transaction mode.
In the specific implementation, the electricity transaction quantity in the transaction pool is monitored and confirmed in real time; and when the transactions in the transaction pool are confirmed to exceed the preset electric power transaction quantity, packaging all the transactions in the current transaction pool, and writing the packaged electric power transactions into a block chain for storage.

wherein the generated power transaction system parameter sysPrm = (h, k, n) 2 ) (ii) a Resulting Pedersen commitment parameter pedPrm = (G, p, G1, h 1) where pedPrm denotes Pedersen commitment parameter, G1 and h1 are two generators of group G of prime order p, sysPrm denotes system parameter, h = G λ modn 2 ，k＝g λ modn 2 N = pq, p and q are both randomly selected security prime numbers, mod represents the remainder calculation, r is a random number, r < n2, g is a random number, and n is the sum of the r and the n 2 Is relatively prime and less than n 2 A multiplicative group formed by the natural numbers of (1), and satisfies (L (g) λ modn 2 ) -1modn exists and satisfies gcd (L (h) λ modn 2 ) N) = =1 present, where λ = lcm (p-1, q-1), lcm representing the power transaction least common multiple calculation, L (g) λ modn 2 )＝(g λ modn 2 -1)/n, gcd represents the calculation of the greatest common divisor of the power transaction, L (h) λ modn2)＝(h λ modn2 -1)/n。
Step S402: and constructing a Pedersen commitment, and calling a sigma protocol to construct an equality evidence for the Pedersen commitment, the power transaction amount ciphertext, the power account original amount ciphertext, the power transaction post-account balance ciphertext and the commitment in the power transaction post-power balance ciphertext.

On the basis of the scheme, an evidence that the transaction amount is in a specific range is constructed for the transaction amount ciphertext of the transaction sender based on the function for generating the zero knowledge range proof, an evidence that the transaction amount is in the specific range is constructed for the account balance ciphertext of the transaction sender after transaction, and the constructed two evidences are generated in an aggregation mode.
Step S403: and constructing a Pedersen commitment for the post-power-transaction account balance ciphertext and the post-power-transaction power balance ciphertext, and constructing an equal evidence for the commitment in the post-power-transaction account balance ciphertext and the post-power-transaction power balance ciphertext by calling a sigma protocol.

After the block is successfully distributed, the system management node broadcasts the latest block chain information to all other nodes.
In specific implementation, when a transaction query request is received, whether the user equipment has a query quota for checking the transaction is judged according to the real information of the user equipment sending the transaction query; if the user equipment has the query quota for checking the transaction, reading the target power transaction data into a trusted execution environment of a block chain node for decryption under the condition that a data query condition is met, sending the decrypted target power transaction data to the user equipment, and performing decrement updating on the query quota of the user equipment; when an electric power transaction reliability query request is received, a block where the electric power transaction is located is searched, and relevant information of the transaction is sent to user equipment, so that a user can confirm the authenticity of the transaction according to digital signatures of both transaction parties, and the transaction content is confirmed to be unmodified according to a hash value of a transaction tree calculated through layer-by-layer splitting.

The formula for calculating the kini coefficient is shown in formula 2,
where k is an arbitrary constant, c is a feature threshold for any one of the attributes, xi is the ith attribute of an element in the sample data set, gini (TXi = c) is a kini coefficient corresponding to the current leaf node divided by c as the feature threshold, T (Xi ≦ c) is a subset composed of elements whose feature values of the divided attributes Xi are less than or equal to c, T (Xi > c) is a subset composed of elements whose feature values of the divided attributes Xi are greater than c, num (T (Xi ≦ c)) is the number of elements in the subset T (Xi ≦ c), num (T (X > c)) is the number of elements in the subset T (Xi > c), gini (T (Xi ≦ c)) is a kini coefficient of the subset T (Xi ≦ c), and Gini (T (Xi > c)) is a kini coefficient of the subset T (Xi > c).
