The Blockchain Trilemma: What is it?

The blockchain trilemma is a concept coined by Vitalik Buterin that proposes a set of three main issues that developers encounter when building blockchains. More often than not, creators are forced to sacrifice one aspect for the sake of the other two.

  • Decentralization – creating a blockchain system that does not rely on a central point of control
  • Scalability – the ability for a blockchain system to handle an increasingly growing amount of transactions
  • Security – the ability of the blockchain system to operate as expected, defend itself from attacks, bugs, and other unforeseen issues

For some in the industry, achieving all three aspects is an impossible feat that will never be done, at least in the near future. 

Fantom is designed to overcome these limitations of old-generation blockchain platforms by providing a steady balance of scalability, security, and decentralization.

Fantom Overview

Fantom operates atop a bespoke “leaderless” PoS consensus mechanism dubbed Lachesis that secures the Fantom network and ensures both transactional speed and security. Lachesis is an aBFT consensus mechanism, which means that network data can be processed at different times, and the network can tolerate up to one third of participants engaging in faulty or malicious behavior without causing undue harm to network processes.

Lachesis also boasts near-instant finality. This means that transactions are confirmed and finalized in an average of one second, without the need to wait for laborious block confirmation as experienced in Proof-of-Work (PoW) networks. By avoiding the relatively lengthy block confirmation process, this aBFT system is much faster and more scalable than many of its Byzantine Fault Tolerant (BFT) counterparts.

The Fantom Foundation has turned its focus towards decentralized finance (DeFi) use cases with the help of Yearn Finance founder Andre Cronje, who serves as a technical advisor to Fantom. Andre has advised and helped promote Fantom’s multi-chain efforts, such as the launch of Fantom’s bridge to Ethereum.

As an ultra-high speed and high-performance platform, Fantom believes it can become the IT infrastructure backbone for the emerging smart cities. With a goal of executing 300,000 transactions per second, and the ability to communicate across multiple service providers, Fantom believes it is the solution to storing vast amounts of data securely.

It hopes to achieve this by being accessible to stakeholders for smart city data-driven smart contracts and dApp adoption. The Fantom team envisions the platform being used across a wide variety of sectors, including public utilities, smart home systems, healthcare, education, traffic management, resource management, and environmental sustainability projects.

Fantom Technology

Fantom features two core technologies:

  1. Lachesis protocol – the core consensus layer
  2. Opera – an application development layer

Lachesis uses a Directed Acyclic Graph (DAG) based algorithm to achieve asynchronous Byzantine fault tolerance (aBFT). Lachesis has four key qualities:

  • Asynchronous: Participants have the freedom to process commands at different times
  • Leaderless: No participant plays a “special” role in block production
  • Byzantine Fault-Tolerant: Supports one-third of faulty nodes
  • Near-Instant Finality: Transactions are confirmed in 1-2 seconds.

Fantom has implemented Lachesis as a consensus layer that can extend to additional layers within the system.

Opera is a permissionless and open-source environment for development. It boasts the full range of smart contract capability that Ethereum has due to its support of the Solidity programming language and integration with the Ethereum Virtual Machine (EVM). Applications built on Fantom can be designed to be interoperable with platforms built on Ethereum, while still maintaining the transactional efficiency of the Fantom network.

A proprietary software development kit (SDK) known as the Fantom Virtual Machine will eventually be released for native Fantom-based development alongside continued support for the EVM — a strategy meant to entice Ethereum-based dApp developers to make an easy transition over to building applications on Fantom.

Fantom DeFi and FTM Token

Fantom promises to be the all-in-one DeFi (decentralized finance) suite for users. Fantom’s EVM-compatible blockchain gives users the ability to mint, trade, lend and borrow digital assets directly from their wallets. And all of this comes with near zero fees and instant transactions, making DeFi ideal on Fantom.

Fantom currently supports the following:

  • Liquid staking – using staked FTM tokens as collateral for DeFi applications. All FTM delegations are liquid within the Fantom ecosystem.
  • fMint – users can mint dozens of synthetic assets on Fantom, including cryptocurrencies, national currencies, and commodities.
  • fLend – lending and borrowing digital assets to trade and to earn interests without losing exposure to held FTM.
  • fTrade – trading Fantom-based digital assets without leaving the wallet. This makes for a fully non-custodial and decentralized AMM exchange.

What is the FTM token?

FTM is the primary token on the Fantom network. FTM tokens and sFTM tokens can be used as collateral to mint fUSD, which can then be used to trade and swap for synthetic tokens and fiat, and much more. All of this is accomplished through the progressive web app Fantom fWallet, where users can store, send, receive, and stake FTM tokens.

Fantom partnerships 

Fantom is working together with Chainlink to build secure and scalable DeFi products like decentralized stablecoins, lending protocols, and synthetic assets. All developers building on Fantom can access Chainlink’s oracle infrastructure. The integration enables the whole Fantom ecosystem to combine tamper-proof real-time data for on-chain and off-chain assets from trusted sources.

Travala, a blockchain-based travel booking platform, is leveraging Fantom to help users book over 3,000,000 travel products worldwide, including hotels, homes, flights, tours, and activities. This will be a huge boost to Fantom’s adoption.

SuperFarm, a growing NFT ecosystem, simplifies the process for builders on projects like Fantom to set up NFT farms and expand use cases for their tokens. In addition to launching exclusive NFT drops for Fantom users, SuperFarm offers Fantom builders new ways to engage their communities. By setting up NFT farms via the SuperFarm platform’s intuitive and simple interface, builders can incentivize community members to stake their tokens, earn rewards, and interact with each other.

DABS is Afghanistan’s national and fastest-growing electricity company. It manages electricity production, import, transmission, and distribution across the country. Fantom has signed an MoU with DABS where they have agreed to cooperate on the digitalization and implementation of advanced audit software within DABS’s operations. This a huge partnership to support smart energy in Afghanistan, which can help more adoption & validation of the Fantom platform.

Fantom has secured many partnerships and integrations in its quest to become the “nervous system for smart cities.” 

More details about these partnerships can be found on their official website:


Fantom’s approach to the DeFi and dApp landscape is innovative — as is its staking reward program structure. Further proposed use cases for Fantom’s highly scalable smart contract platform are dApps related to supply chain management, payments, and smart city programs, some of which are already being piloted around the world.

As the first of its kind with its complex and unique infrastructure, Fantom’s approach to fast, scalable dApp development is still establishing its place in the wider blockchain ecosystem. Although there is already much competition in the burgeoning dApp sector, the speed and benefits that Fantom offers dApp developers are notable, and the platform is poised to gain further traction.


What is Fantom?

What does Fantom do?

The Fantom network architecture intends to provide a viable solution to the blockchain trilemma by providing a steady balance of scalability, security, and decentralization.

How does Fantom work?

Fantom’s fast, scalable platform for decentralized applications (dApps) draws its speed from a unique consensus mechanism called Lachesis. Fantom also offers tools that make it easy to integrate existing dApps, a nuanced system of staking rewards, and a suite of built-in decentralized finance (DeFi) tools.

What is Lachesis?

Fantom is a Layer-1 blockchain that uses a single consensus layer to support the creation of multiple execution chains. The network’s independent consensus layer called Lachesis, featuring a novel consensus mechanism developed by the Fantom Foundation dubbed the “Lachesis Protocol.” Lachesis can provide security to multiple other layers, the first of which is Fantom’s EVM-compatible smart contract chain called Opera.

Has Fantom been adopted?

Yes. Fantom is an ambitious project that has already partnered with numerous blockchain projects, as well as governments and enterprises.
