Spore Protocol

The Spore Protocol is an on-chain protocol designed to empower the ownership, distribution, and value capture of unique digital objects (DOBs) known as Spores.

How Spore Protocol Works

Spore Protocol embeds value into on-chain digital objects (DOBs) using two Cell types: Spore Cell and Spore Cluster Cell. Spore Cells are fundamental, while Spore Cluster Cells are optional extensions providing extra information.

Spore

A Spore is an on-chain DOB backed by CKBytes. Unlike traditional NFTs that rely on external market demand for their value, Spores offer intrinsic value at minting and potential for value growth. Holders can "melt" their Spores at any time to retrieve the underlying CKBytes.

Data Structure

data:
    content-type: Bytes # String Bytes
    content: Bytes
    # OPTIONAL
    cluster_id: Bytes
type:
    hash_type: "data1"
    code_hash: SPORE_TYPE_DATA_HASH
    args: SPORE_ID
lock:
    <user_defined>

• content-type: Specifies the content format (e.g., image/png) following MIME standards. It can include parameters (e.g., immortal=true for indestructible Spore).
• content: Main content of the Spore.
• cluster_id: Optional field for categorizing the Spore into a series or collection.
• type: Type Script set to SPORE_TYPE_DATA_HASH with SPORE_ID as an argument following the rules of Type ID Script
  • SPORE_ID = hash(this_transaction.inputs[0]) | Output_Index_Of_This_Cell

note

All fields in a Spore Cell are immutable once created.

Cluster

A Cluster organizes multiple valuable digital objects (DOBs). Each Spore can be linked to only one Cluster, while each Cluster can associate with many Spores.

• Cluster Types: Clusters can be Public or Private. Public Clusters allow anyone to tag a Spore, while Private Clusters restrict tagging to the owner during minting.
• Permanent Storage: Clusters are designed to be indestructible once created, ensuring permanent on-chain presence.

Data Structure

data:
    name: Bytes # String Bytes
    description: Bytes # String Bytes
type:
    hash_type: "data1"
    code_hash: CLUSTER_TYPE_DATA_HASH
    args: CLUSTER_ID
lock:
    <user_defined>

• name: Name of the Spore Cluster.
• description: Textual description of the Cluster.
• type: Type Script set to CLUSTER_TYPE_DATA_HASH with CLUSTER_ID as an argument following the rules of Type ID Script
  • CLUSTER_ID = hash(this_transaction.inputs[0]) | Grouputput_index_of_this_cell

note

All fields in a Spore Cluster Cell are immutable once created.
