Here's the shortest guide to four red-hot segments of the cryptocurrency sphere created by GetBlock, a leading nodes connection vendor for 40+ blockchains.

Digital collectibles or non-fungible tokens (NFTs) represent the class of cryptocurrency tokens with unique characteristics verified by blockchain cryptographic power. Say, we can’t see the difference between one Ether stored in Alice’s wallet and one Ether proudly owned by Bob.

As such, the tokens of major blockchains are ‘fungible’: ETH or BTC coins are interchangeable. NFTs work differently: every ‘non-fungible’ tokens can be customized and therefore defined from its analogues.

This feature allows crypto enthusiasts to save, store and exchange pictures, videos, music tracks as NFTs. As the segment is on fire, the prices for NFTs are rocketing.

The prices in this sphere have nothing to do with ‘real-world’ value of the underlying files: as covered by GetBlock, an NFT artist recently sold himself a ‘CryptoPunk’ NFT for more than $0.5 billion.

Decentralized finances protocols (decentralized finances or DeFi) should be referred to as a sort of decentralized (on-chain, i.e. based on smart contracts only) software applications suitable for basic financial operations: lending/borrowing, stablecoins minting, ‘yield farming’ (earning passive income for providing liquidity to DeFis), and so on.

Ideologically, DeFis replace classic banking institutions allowing to earn and trade digital assets with no KYC. DeFis are considered to be ‘non-custodial’ and anonymous ecosystems: they don’t use centralized servers and wallets for customers’ funds, personal data and keypairs.

DeFis euphoria started in Q3, 2021 with ‘yield farming’ mania: crypto enthusiasts were switching between protocols seeking for the best rewards rate. This process catalyzed the interest in ‘DeFi tokens’, native cryptocurrencies of DeFi protocols.


GameFi (‘gamified finances protocols’, combination of ‘gaming’ and ‘DeFi’) applications are blockchain-based games that incentivize users to join them by financial motivations. ‘Play-to-Earn’ (PoE) is the second name for this type of protocols.

As such, GameFi protocols provide their users with the opportunity to earn money by their gaming skills. Unlike traditional online MMORPGs, the transactions and characters of GameFi protocols are stored on blockchains: Ethereum, Binance Smart Chain, Tron, Polygon, and so on.

Actually, the majority of decentralized gaming protocols are built on the intersection between DeFi and NFT segments.

As you may know, they are different blockchains: Bitcoin, Ethereum, Eos and so on. While each of them rely on distributed networks of nodes, they have different designs.

However, in 2021, the market badly needs the systems that would allow different blockchains to interact seamlessly. Say, the DeFi sphere is interested in interactions (‘bridges’) between Ethereum and Bitcoin, Ethereum and Eos, and so on.

While typically such problems are addressed with two-way bridges, there is a class of applications specially designed for cross-networks integration. Polkadot and Cosmos represent the most popular protocols of this scene.

Tokens to watch: DOT, KSM, ACA, KAR, ATOM

Imagine: GetBlock connects to blockchain nodes all types of applications listed above! Our ecosystem of nodes endpoints turn blockchains into decentralized back-end platforms for DeFis, GameFis, NFT marketplaces, and so on.
