Inputs

Input	Type	Validator	Description
Index Spend	Script	index-validator	Index UTxO for linked list insertion
Index Node Prev	Script	index-validator	Previous node (to update next pointer)
User UTxO	Wallet	-	User's UTxO for collateral/fees

Outputs (5)

Output	Validator	Value	Description
Index Node 1	index-validator	~1.25 ADA + space token	Index linked list node
Index Node 2	index-validator	~1.25 ADA + space token	Index linked list node
Protocol Treasury	wallet	5 ADA	Service fee
Global State	global-state-v2	~1.26 ADA + g-token	User's global state
User Wallet	wallet	~1.15 ADA + u-token	User receives access token

Minting Operations (3)

Policy	Token Name	Quantity	Purpose
index-policy	0x20 (space)	+1	Index linked list marker
index-policy	g{alias}	+1	Global state token (g prefix)
index-policy	u{alias}	+1	User access token (u prefix)

Token Prefixes

The index-policy mints tokens with different prefixes:

u - User access token (held in wallet)
g - Global state token (locked at validator)
0x20 (space) - Index linked list marker

Global State Datum

Constructor 0:
├── alias: "{user_alias}"
└── local_state_information: Map (empty)

The local_state_information map is empty initially and gets populated when enrolling in courses.

Observers (Withdrawals)

Observer	Purpose
index-observer	Validates index linked list operations

Key Notes

This is the entry point for all protocol participation
Alias must be unique across the protocol (enforced by linked list)
5 ADA service fee goes to protocol treasury
Access token is required for all subsequent transactions
The g-token and u-token share the same policy but different names
