+## Milestone 1
+
+**User Paid Fees and Sponsored. Finish/Debug white listing and spam/DOS protection**
+
+Implementation of two models 
+If collection sponsor is set and confirmed for collection instance that means Sponsored Economic Model has chosen. Otherwise default economic model User Paid Fees is set.
+For Sponsored Economic Model exists timeouts for token transactions. For every NFT type timeouts defined separately. Timeouts and white list limits together prevented spam and malicious actions.
+
+Set sponsor
+`nft`.`set_collection_sponsor`
+Confirm sponsor
+`nft`.`confirm_sponsorship`
+
+A white list mode presented by collection property `access` and can be enabled with `set_public_access_mode`. Rules provide spam/DOS protection
+While collection in the white list mode rules below are active:
+Owner can add address to white list
+Admin can add address to white list
+Non-privileged user cannot add address to white list
+Owner can remove address from white list
+Admin can remove address from white list
+Non-privileged user cannot remove address from white list
+If Public Access mode is set to WhiteList, tokens can’t be transferred from a non-whitelisted address with transfer or transferFrom
+If Public Access mode is set to WhiteList, tokens can’t be transferred to a non-whitelisted address with transfer or transferFrom
+If Public Access mode is set to WhiteList, tokens can’t be destroyed by a non-whitelisted address (even if it owned them before enabling WhiteList mode)
+If Public Access mode is set to WhiteList, token transfers can’t be Approved by a non-whitelisted address (see Approve method).
+If Public Access mode is set to WhiteList, tokens can be transferred to a whitelisted address with transfer or transferFrom
+If Public Access mode is set to WhiteList, tokens can be transferred from a whitelisted address with transfer or transferFrom 
+If Public Access mode is set to WhiteList, and Mint Permission is set to false, tokens can be created by owner.
+If Public Access mode is set to WhiteList, and Mint Permission is set to false, tokens can be created by admin.
+If Public Access mode is set to WhiteList, and Mint Permission is set to false, tokens cannot be created by non-privileged and white listed address.
+If Public Access mode is set to WhiteList, and Mint Permission is set to false, tokens cannot be created by non-privileged and non-white listed address.
+If Public Access mode is set to WhiteList, and Mint Permission is set to true, tokens can be created by owner.
+If Public Access mode is set to WhiteList, and Mint Permission is set to true, tokens can be created by admin.
+If Public Access mode is set to WhiteList, and Mint Permission is set to true, tokens cannot be created by non-privileged and non-white listed address.
+If Public Access mode is set to WhiteList, and Mint Permission is set to true, tokens can be created by non-privileged and white listed address.
+
+**Add missing custom types (CollectionMode, FungibleItemType, ReFungibleItemType)**
+
+Follow types defined
+```
+pub struct NftItemType<AccountId> {
+    pub collection: u64,
+    pub owner: AccountId,
+    pub data: Vec<u8>,
+}
+pub struct FungibleItemType<AccountId> {
+    pub collection: u64,
+    pub owner: AccountId,
+    pub value: u128,
+}
+pub struct ReFungibleItemType<AccountId> {
+    pub collection: u64,
+    pub owner: Vec<Ownership<AccountId>>,
+    pub data: Vec<u8>,
+}
+```
+
+**Add substrate bounds for number of collections, owned tokens, and number of collection admins.**
+
+Bounds defined in chain specification and can be set with 'sudo' privileges `nft`.`set_chain_limits`.
+
+**Add/document extra genesis**
+
+Extra genesis defined in `node/src/chain_spec.rs` file. Configuration consist from 5 items:
+Collection list,  Nft items list, Fungible items list, Refungible items list, Chain limits
