If you're looking for ways to generate passive income, you may have considered investing in the blockchain industry. After all, blockchain is one of the most innovative and rapidly-growing industries out there. And while there are certainly some risks involved, there's also huge potential for rewards.

In the cryptocurrency world, the term "passive income" is used a lot. It refers to the income that you earn without having to put in any active effort. In other words, it's money that comes in without you having to do anything for it.

There are a lot of ways to earn passive income in the blockchain industry. Here are 14 of them:

1. Staking - Staking is when you lock up your coins in a wallet to help secure the network and in return, you earn interest on those coins. The more coins you stake, the more interest you earn. When you stake your coins, you are essentially locking them up in a wallet to help secure the network. In return for your help, you earn interest on those coins. 

2. Masternodes - Masternodes are similar to staking but usually require a larger investment. They also tend to yield higher returns. With a masternode, you can earn rewards for processing transactions and helping to secure the network.

3. Dividends - Some cryptocurrencies offer dividends to their investors. This is usually a percentage of the coins that they hold. For example, NEO holders get dividends in the form of GAS.

4. Affiliate Programs - Many companies in the blockchain industry offer affiliate programs. This is where you can earn commissions for referring people to their products or services.
