NKN (New Kind of Network) is a digital currency that powers a decentralized network for data transmission. The NKN token serves as the native utility token within the network, facilitating various functions to ensure the smooth operation and growth of the NKN ecosystem. Here are some key ways NKN is used:

1. Decentralized Data Transmission Network (DDTN): NKN introduces the concept of DDTN, which combines multiple independent and self-organized relay nodes to provide clients with connectivity and data transmission capabilities. This coordination is decentralized and does not require trust among involved parties.

2. Proof of Relay (PoR) Consensus Mechanism: Unlike traditional Proof of Work (PoW) mechanisms, NKN uses PoR, where miners are rewarded for relaying useful or real-world data over the network. This ensures the efficiency and security of the NKN network.

3. Native Token Incentives: The NKN token incentivizes users to share their network connections and utilize unused bandwidth, resulting in a more efficient and robust network. Users receive NKN tokens as rewards for contributing to the network.

4. Developer-Friendly Features: NKN offers tools and products such as nConnect, nMobile, and dataRide, which enhance the user experience and provide resources for developers to build and launch new applications on the network.

5. Decentralized Communication and IoT Connectivity: NKN can be used for various applications, including decentralized communication, IoT connectivity, and distributed cloud storage, providing a wide range of possibilities for adoption and growth.

Overall, NKN is designed to revolutionize internet connectivity and data transmission by leveraging blockchain technology and decentralized networking principles.

To store NKN tokens, you have several options:

1. Private Wallets: Use NKN's official web-based token swap tool if you hold tokens in private wallets. This tool allows you to swap your NEP-5 tokens for ERC-20 tokens.

2. Kriptomat: You can purchase and store NKN tokens on Kriptomat, a platform that provides a secure and simple way to buy and manage cryptocurrencies. Kriptomat supports various payment methods, including credit/debit cards and SEPA bank transfers.

3. Cold Storage: You can store NKN tokens in cold storage using hardware wallets like Ledger Nano S/X. Since NKN is an ERC-20 token, it can be stored under the Ethereum chain on these devices.

4. NKN Node Wallet: If you are running a full NKN node, you can use the nknc wallet command to create a wallet. This wallet should be unique for each node to ensure proper network functionality.

5. Exchanges: You can also store your NKN tokens on exchanges that support the token, such as those that allow swapping between NKN Mainnet and NKN ERC-20 tokens.
