Follow Node

Introduction

The follow node is an integral part of the MetaID specification, allowing users to create and maintain their social relationships within the blockchain network. By utilizing follow, we can significantly enhance the social capabilities of MetaID, providing users with a richer and more in-depth interaction experience.

Spec

The script format for the follow protocol is as follows:

OP_FALSE
OP_IF
	metaid                           
	create                          
	/follow                         
	0                               
	0                                
	application/json;utf-8         
	{metaid}                        
OP_ENDIF

Conventions for follow

1. In the follow format, create represents a follow action, while revoke represents an unfollow action.

2. In the revoke operation, the path must locate a valid PIN, and this PIN must be a valid follow PIN.

Example

Taking user A following user B as an example:

• User A's MetaID: c08c4e96514ee5c4f91b6df3de7a42f797a36af7265918a6b74d5198f87682ad

• User B's MetaID: 2464ad8d35e601f8b73c80976104ff00e878f58dc2f2936ec3a269fe34d962c2

The script operation for user A to follow user B is as follows:

OP_FALSE
OP_IF
	metaid                         
	create                         
	/follow                        
	0                              
	0                              
	application/json;utf-8         
	2464ad8d35e601f8b73c80976104ff00e878f58dc2f2936ec3a269fe34d962c2 
OP_ENDIF

After the follow PIN is committed to the blockchain, the generated pinId is: dcvv5d4377f36c7c2466259593d0d4a0c1e5d7ec19500e082ce1eea3993f22b1aac1i0

Then, the script operation for user A to unfollow user B is as follows:

OP_FALSE
OP_IF
	metaid                         
	revoke                         
	@dcvv5d4377f36c7c2466259593d0d4a0c1e5d7ec19500e082ce1eea3993f22b1aac1
	OP_0                           
	OP_0                           
	OP_0                           
	OP_0                            
OP_ENDIF

Both follow and unfollow operations take effect immediately and generate corresponding records on the blockchain.
