The invention discloses electronic voting method, device and equipment and a computer storage medium. The method applied to the voting server comprises the following steps: receiving encrypted k votessent by a voting terminal; receiving a second confirmation code sent by the voting terminal, wherein the second confirmation code is obtained by performing Lagrange interpolation calculation on k option values corresponding to k votes; comparing the second confirmation code with a pre-generated first confirmation code, and completing the verification of voting validity according to a comparison result; the encrypted k votes passing the verification are signed and stored in a block chain, wherein the k option values are included in n voting option values, and the n voting option values are obtained by sharing the first confirmation code by using a threshold secret sharing scheme. According to the embodiment of the invention, the effectiveness of the votes of the voters can be verified on the basis of not decrypting the votes of the voters, the overall safety is high, and the voting accuracy is improved.
