While independent Fantom nodes will occasionally communicate with one another about transactions and events, they do not confirm finalized blocks or the overall state of the network. This architecture results in a system that processes transactions quickly and achieves finality within seconds. Fantom stresses that its PoS mechanism is leaderless, which means there are no block leaders and no participants have a special role in its operation. Anyone can join or leave the node network at any point, and all nodes hold equal weight in the consensus protocol.
To provide scalability to the whole ecosystem and avoid network congestion, applications built on Fantom effectively use their own independent blockchains. Because each dApp gets its own blockchain, each can be configured to meet its particular needs. Tokenization, tokenomics and governance are all modular pieces to the puzzle that can be customized by each dApp as needed without affecting the underlying structure of Fantom’s Lachesis consensus layer.
However, each independent dApp blockchain remains plugged into the Lachesis PoS consensus protocol, and thus benefits from its underlying speed and security. With Lachesis as the common thread tying these independent blockchains together, all Fantom dApps benefit from inherent interoperability, and can easily communicate with one another. With these features in mind, Fantom is working to make a case for why dApp developers should make the switch from Ethereum to Fantom.
Fantom’s native utility token — FTM — powers the entire Fantom blockchain ecosystem. FTM tokens are used for staking, governance, payments, and fees on the network.
Anyone can participate in Fantom staking with a minimum stake of 1 FTM by moving their FTM to a Fantom wallet address. When doing so, ERC-20 FTM tokens and BEP-2 FTM tokens will automatically be swapped for Opera FTM coins. Also, to operate a validator node on Fantom’s permissionless network, validators must stake at least 3,125,000 FTM.

Fantom’s approach to the DeFi and dApp landscape is innovative — as is the structure of its staking reward program. Further proposed use cases for Fantom’s highly scalable smart contract platform are dApps related to supply chain management, payments and smart city programs, although its permissionless nature means its actual use cases will likely far exceed these prescribed categories.
With its first-of-kind complex and unique infrastructure, Fantom’s approach to fast, scalable dApp development is still establishing its place in the wider blockchain ecosystem.
Some developers, like those building Loopring, Abritrum and Optimism, opted to build layer-2, or L2, solutions to speed up the Ethereum experience without getting rid of Ethereum’s security.
The future of FTM will be determined by the victor of the L1 wars. Right now, Ethereum is losing ground to emergent rival Layer 1 blockchains, like Solana, Fantom and Avalanche.
Time will tell whether the crypto industry becomes a winner-takes-all market where a single blockchain dominates, or if crypto will indulge in a multi-chain future where blockchains become application-specific.
Fantom is a decentralized, and open-source smart contract platform for and digital assets — one of many blockchain networks built to provide an alternative to . The Fantom blockchain mainnet went live in December 2019 and its network architecture intends to provide a viable solution to the by providing a steady balance of scalability, security, and decentralization.
Like other Ethereum alternatives, Fantom intends to provide more scalability and lower costs than the legacy first-mover smart contract platform is able to provide in its iteration. A unique element of the Fantom crypto platform is that users can create and deploy their own independent networks instead of relying solely on Fantom’s main consensus layer.
Each application built on Fantom operates on its own unique blockchain. While operating on its own blockchain, each Fantom dApp also enjoys the security, speed and of the parent Fantom blockchain. Further, independent blockchains are modular in structure, which allows developers to configure them to their particular project’s use case.
Fantom Network is best conceptualized as a parent network composed of individual child networks that host dApps of all shapes and sizes. Fantom’s infrastructure is tied together through its consensus mechanism, which maintains the operational efficiency of the entire network. The aBFT network structure is designed to preserve network security while maximizing speed.
Fantom operates atop a bespoke "leaderless” PoS consensus mechanism dubbed '' 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 as much as 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 are confirmed and finalized within only a few seconds, without the need to wait for laborious block confirmation as experienced in networks. By avoiding the relatively lengthy block confirmation process, this aBFT system is much faster and more scalable than many of its counterparts.
Diving deeper into how Fantom’s Lachesis functions, we see how each network node contains its own , which records the chronology of 'event blocks' and respective transactions, with each node achieving internal consensus independently. Confirmed batches of event blocks are then compiled into finalized blocks that are confirmed on the wider Fantom network. Finalized blocks, which form the base layer Fantom blockchain, are composed of confirmed event blocks from the independent nodes.
The Lachesis consensus apparatus servers power Fantom’s mainnet deployment platform — — which hosts dApps operating on the network. Opera is a and open-source environment for development that boasts the full range of smart contract capabilities that Ethereum has due to its support of the Solidity programming language and integration with the . 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 known as the 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 to building applications on Fantom.
There is a total supply of 3.175 billion FTM coins, with 2.5 billion in circulation as of September 2022 The remainder will be distributed as Fantom staking rewards. FTM is available as a native mainnet coin, an in the Ethereum ecosystem and a in the Binance ecosystem.
Fantom provides a fairly dynamic and lucrative staking structure for users. Users can stake their FTM at-will with a validator node for a 4% staking reward, which is a common staking model. However, users can also take advantage of Fantom’s Fluid Rewards by choosing to lock up FTM for a predetermined time — ranging from two weeks to a year — to secure higher reward rates of as much as 12% APY.
Fantom also employs a feature called , whereby stakers can mint sFTM at a 1:1 ratio to their staked FTM to be used as collateral in Fantom Finance — a suite of DeFi apps provided by Fantom — thus allowing users to get more use out of their staked FTM. Some of the DeFi offerings that Fantom provides include:
Fantom’s success is best understood in the context of the so-called L1 wars. Ethereum is slow and expensive to use, and will remain so (assuming activity remains the same) until to the protocol are implemented. That could take a couple of years. This is too late for people who want to make the most of decentralized finance protocols today, but who find ETH native DeFi apps too expensive to use.
Other blockchains decided to replace Ethereum entirely — Ethereum is known as the base layer, L1 or layer 1. Solana, Avalanche, and Fantom are the leading horses in this race.
