Methods

asArray

asArray(): bigint[]

Returns

bigint[]

bigint[] - the command as an array

Notice

Returns this Command as an array. Note that 5 of the Command's fields are packed into a single 250-bit value. This allows Messages to be smaller and thereby save gas when the user publishes a message.

Parameters

NameType

sharedKeyEcdhSharedKey

Returns

Message

Notice

Encrypts this command along with a signature to produce a Message. To save gas, we can constrain the following values to 50 bits and pack them into a 250-bit value: 0. state index 3. vote option index 4. new vote weight 5. nonce 6. poll ID
