Register

Register an account by public key

Registering an account isn't needed to use LTO You can simply sign and broadcast transactions. The register transaction publishes a public key, so a new account can be used for a DID verification method.

• id and height should be omitted when broadcasting. These fields are set by the node.

• Binary strings are base58 encoded.

• timestamp is in microseconds since epoch.

• fee includes 8 digits, so LTO * 10^8

Binary schema

The binary data structure of the unsigned transaction.

V3 (current)

#	Field Name	Type	Length
1	Transaction type	Byte (constant, value=20)	1
2	Version	Byte (constant, value=3)	1
3	Network id	Byte	1
4	Timestamp	Long	8
5	Sender's key type	KeyType (Byte)	1
6	Sender's public key	PublicKey (Array[Byte])	32 | 33
7	Fee	Long	8
8	Number of accounts	Short	2
9	Account 1 key type	KeyType (Byte)	1
10	Account 1 public key	PublicKey (Array[Byte])	32 | 33 | 48
...

• Account key type and public key is repeated for each account.

• Network id can be obtained by taking the 2nd byte from the sender address.

• Each key type has a numeric id in addition to the reference from the JSON.
• Integers (short, int, long) have a big endian byte order.
