Examples

Assuming the address: 19Up4xZ4Y6CBhUcXSQZdo7tHaGNYFn7EUj, according to the protocol, its inherent MetaID is: 8a15022dd74648c5158d237f41e544e6097b3f27dcc85788a4b7470c063ed33c

According to the agreement, the following paths are reserved

• /info: Stores user's basic information such as username and avatar.

• /protocols: Used for application protocol operations.

• /file: For file data storage.

• /ft: For storing user's fungible token (FT) asset actions.

• /nft: For storing user's non-fungible token (NFT) asset actions.

• /follow: Stores user's follow list data.

2. Create Username and Avatar

Users can set their username and avatar by constructing PIN transactions:

1. Set Username: User sets their name to Alice with the path as /info/name.

2. Set Avatar: User sets a specific avatar with the path as /info/avatar.

Both paths are under the /info directory, indicating they are part of the user's personal information.

Set Username:

Submitting SimpleBuzz Protocol

Assume a user wants to post a buzz, they need to create and submit a new PIN in the /protocols/simplebuzz section.

This adds the buzz data to the /protocols/simplebuzz path, indicating it is a record under the user's SimpleBuzz protocol.

OP_FALSE
OP_IF
	metaid

Modification

When performing a modify operation, use the @ symbol to point to the PIN to be modified. For example, to modify a specific PIN, use @{PINID}.

OP_FALSE
OP_IF
	metaid

Revocation

When performing a revoke operation, use the @ symbol to point to the PIN to be revoked. For example, to revoke a specific PIN, use @{PINID}.

OP_FALSE
