  Ʉnlock is a protocol for memberships built on a blockchain.

  

  I'm here to show you how simple the process is for token gating content in an Express.js application using the Ʉnlock Protocol. Ʉnlock is a protocol for memberships that allows anyone to deploy a "lock" (a membership smart contract). The contract specifies the terms of the membership: including price, duration, number of members, and many more parameters necessary to run a thriving membership subscription. When a supporter wants to join your membership, they simply pay the specified amount to the contract and will receive an NFT that represents the purchased membership.

  Requirements: you need to use an ethereum/web3 wallet such as MetaMask. We will be using a the Rinkeby test network for this tutorial (no need to spend real money, get some fake Ether on this faucet), and when you decide to ship, you can use Ethereum's mainnet, or the xDAI and Polygon networks if you want to skip the high gas fees.
