DeFi trends in 2021 that you can use in your business

DeFi has seen a gigantic growth of nearly 1000% in 2020, and as decentralized finance continues to gain popularity, this number continues to grow. What DeFi trends will be crucial this year?

By the end of last year, the total value locked up in DeFi had managed to exceed $26 billion. By comparison, just a year ago there was just 831 million locked up in DeFi protocols. DeFi's incredibly rapid growth in 2020 helped set the stage for another wave of adoption in 2021. Because despite such rapid growth, DeFi still remains a very young industry with plenty of room for innovation. 

If so, what DeFi trends are worth keeping an eye on in 2021?

Proof of Stake (PoS) as a consensus mechanism

One of the most important DeFi trends in 2021 will definitely be the displacement of Proof-of-Work (PoW) by Proof of Stake. PoW is currently the most common consensus algorithm used in blockchain networks to confirm transactions. Its operation relies on the use of computing power to secure and verify data. 

So-called miners play a key role for its operation. Essentially, "mining" is the process of creating a block of transactions to be added to the blockchain. The function of miners is thus to process pending transactions in exchange for rewards in the form of cryptocurrency, such as ETH in Ethereum (respectively, 2 ETH for each block generated).

Generating a block requires the use of a lot of computing power due to the difficulty level set by the Blockchain protocol. It is proportional to the total amount of computing power used for mining and serves as a way to protect the network from attacks, as well as tune the rate at which subsequent blocks are created.

Disadvantages of PoW:

  • high energy intensity
  • networks prone to centralization of extraction
  • - limited scalability
  • - relatively low throughput

It was Ethereum, the world's most popular Blockchain protocol, that initiated the widespread transition from Proof-of-Work to Proof-of-stake algorithm. In 2021 with the next phases of updates - Ethereum 2.0, Ethereum networks will fully transition to PoS.

DeFi trends : What changes PoS brings?

  • Significantly lower energy consumption 
  • improved scalability 
  • decentralisation behaviour

Proof of stake is a consensus process by which a cryptocurrency becomes a validator for a Blockchain network. By using PoS, the security of the network is achieved through financial commitments rather than the consumption of computing power - energy. The validator runs software that confirms the transaction and adds new blocks to the chain. 

To become a full validator in Ethereum 2.0 , you will need 32 ETH. However, there will be an opportunity to join a pool of smaller validators and thus offer a smaller stake. When processing transactions, validators will take care to maintain consensus over the data and thus the security of the entire network.

DeFi trends

Liquidity of pledged tokens

However, PoS has one drawback: validators receive rewards for staking, but at the same time they freeze the pledged funds. In 2021, it is definitely worth watching what solutions to this problem the market will come up with.

Already today, DeFi platforms are starting to allow validators to create synthetic versions of their pledged tokens, which can then be used in cryptoeconomics. An example of this is Fantom's Liquid Staking, which allows pledged tokens to be converted into sFTMs, which can then be traded on Fantom Finance or used to mint stablecoins.

The ability to give liquidity to pledged funds makes this form of investment significantly more attractive. Therefore, due to the growing importance of PoS, it can be expected that the increase in the popularity of such solutions will be one of the most important trends in DeFi in 2021.

DeFi Trends: Stablecoins

Currently, stablecoin supply has surpassed $26 billion, with $20 billion added to the market through 2020 alone. Tether USDT has remained the main player for years, holding as much as 79% dominance. The stablecoin market is thus invariably dominated by the US dollar. However, as the sector matures and the macroeconomic effects of government stimulus packages become apparent, we can expect stablecoin secured in other currencies to grow rapidly in popularity as well.

Increase in importance of DEX

The latest report from Kraken Intelligence finds that nearly 96% of blocked ETH is on decentralized exchanges - DEX or lending protocols. While the amount of ETH blocked in lending protocols still outpaces that on decentralized exchanges, the growth for DEX in 2020 was far more robust. The total amount of ETH on the DEX grew by as much as 2,800%, when it only grew by 60% on lending protocols. The report indicates that at this rate, "DEX will soon control the vast majority of TVL (ETH) in the DeFi space."

DeFi trends in 2021 - summary

The year 2020 was undoubtedly an extremely favorable time for decentralized finance. That's when DeFibecame a permanent fixture in the blockchain community, attracting the attention of even those not previously associated with the technology.

But what if 2021 turns out to be an even better year for the sector? The growing public interest and numerous innovations aimed at improving scalability make it possible to consider such an eventuality highly probable. That's why many DeFi enthusiasts are looking at the current year with an almost decreasing optimism.

Blockchain for Creators: Secure and Sustainable Infrastructure

Blockchain for Creators: Secure and Sustainable Infrastructure

In today’s digital creative space, where the lines between art and technology are constantly blurring, projects like MARMALADE mark the beginning of a new era - one where creators can protect their work and maintain ownership through blockchain technology.

For Nextrope, being part of MARMALADE goes far beyond implementing features like screenshot blocking or digital watermarking. It’s about building trust infrastructure - systems that empower creators to thrive in the digital world safely and sustainably.

A new kind of blockchain challenge

Cultural and educational projects come with a completely different set of challenges than typical DeFi systems. Here, the focus isn’t on returns or complex smart contracts - it’s on people: artists, illustrators, educators.

That’s why our biggest task was to design secure yet intuitive infrastructure - lightweight, energy-efficient, and accessible for non-technical users exploring Web3 for the first time.

“Our mission wasn’t to build another financial protocol. It was to create a layer of trust for digital creators.”
— Nextrope Team

Security that stays invisible

The best security is the kind you don’t notice.
Within MARMALADE, we focused on making creators' protection seamless:

  • Screenshot blocking safeguards artworks viewed in browsers.
  • Dynamic watermarking helps identify unauthorized copies.
  • Blockchain registry ensures every proof of ownership remains transparent and immutable

“Creators shouldn’t have to think about encryption or private keys - our job is to make security invisible.”

Sustainability by design

MARMALADE also answers a bigger question - how to innovate responsibly.
Nextrope’s infrastructure relies on low-emission blockchain networks and modular architecture that can easily be adapted for other creative or cultural initiatives.

This means the technology built here can support not only artists but also institutions, universities, and educators seeking to integrate blockchain in meaningful ways.

Beyond technology

For Nextrope, MARMALADE is more than a project — it’s proof that blockchain can empower culture and creators, not just finance. By building tools for digital artists, we’re helping them protect their creativity and discover how technology can amplify human expression.

Plasma blockchain. Architecture, Key Features & Why It Matters

Plasma blockchain. Architecture, Key Features & Why It Matters

What is Plasma?

Plasma is a Layer-1 blockchain built specifically for stablecoin infrastructure combining Bitcoin-level security with EVM compatibility and ultra-low fees for stablecoin transfers.

Why Plasma Blockchain Was Created?

Existing blockchains (Ethereum, L2s, etc.) weren’t originally designed around stablecoin payments at scale. As stablecoins grow, issues like congestion, gas cost, latency, and interoperability become constraints. Plasma addresses these by being purpose-built for stablecoin transfers, offering features not found elsewhere.

  • Zero-fee transfers (especially for USDT)
  • Custom gas tokens (separate from XPL, to reduce friction)
  • Trust-minimized Bitcoin bridge (to allow BTC collateral use)
  • Full EVM compatibility smart contracts can work with minimal modifications

Plasma’s Architecture & Core Mechanisms

EVM Compatibility + Smart Contracts

Developers familiar with Ethereum tooling (Solidity, Hardhat, etc.) can deploy contracts on Plasma with limited changes making it easy to port existing dApps or DeFi, similar to other EVM-compatible infrastructures discussed in the article „The Ultimate Web3 Backend Guide: Supercharge dApps with APIs".

Gas Model & Token Mechanism

Instead of forcing users always to hold XPL for gas, Plasma supports custom gas tokens. For stablecoin-native flows (e.g. USDT transfers), there is often zero fee usage, lowering UX friction.

Bitcoin Bridge & Collateral

Plasma supports a Bitcoin bridge that lets BTC become collateral inside smart contracts (like pBTC). This bridges the security of Bitcoin with DeFi use cases within Plasma.
This makes Plasma a “Bitcoin-secured blockchain for stablecoins".

Security & Finality

Plasma emphasizes finality and security, tuned to payment workloads. Its consensus and architecture aim for strong protection against reorgs and double spends while maintaining high throughput.
The network launched mainnet beta holding over $2B in stablecoin liquidity shortly after opening.

Plasma Blockchain vs Alternatives: What Makes It Stand Out?

FeaturePlasma (XPL)Other L1 / L2
Stablecoin native designusually second-class
Zero fees for stablecoin transfersrare, or subsidized
BTC bridge (collateral)only some chains
EVM compatibilityyes in many, but with trade-offs
High liquidity early✅ (>$2B TVL)many chains struggle to bootstrap

These distinctions make Plasma especially compelling for institutions, stablecoin issuers, and DeFi innovators looking for scalable, low-cost, secure payments infrastructure.

Use Cases: What You Can Build with Plasma Blockchain

  • Stablecoin native vaults / money markets
  • Payment rails & cross-border settlement
  • Treasury and cash management flows
  • Bridged BTC-backed stablecoin services
  • DeFi primitives (DEX, staking, yield aggregation) optimized for stablecoins

If you’re building any product reliant on stablecoin transfers or needing strong collateral backing from BTC, Plasma offers a compelling infrastructure foundation.

Get Started with Plasma Blockchain: Key Steps & Considerations

  1. Smart contract migration: assess if existing contracts can port with minimal changes.
  2. Gas token planning: decide whether to use USDT, separate gas tokens, or hybrid models.
  3. Security & audit: focus on bridge logic, reentrancy, oracle risks.
  4. Liquidity onboarding & market making: bootstrap stablecoin liquidity, incentives.
  5. Regulation & compliance: stablecoin issuance may attract legal scrutiny.
  6. Deploy MVP & scale: iterate fast, measure gas, slippage, UX, security.
