- Released the Fantom testnet in 12-2018. Had its mainnet launch (27-12-2019). Two quarters later then had been anticipated.
- From CMC (9-3-2020):
"FANTOM is a Directed Acyclic Graph (DAG) based Smart Contract platform that aims to solve the scalability issues of distributed ledger technologies. The platform aims to differentiate itself with its “Lachesis Protocol” , which will be integrated with Fantom OPERA Chain. The goal is to support the development of dApps that to enjoy instant transactions and near zero transaction costs for all users."
Audits & Exploits
- Fantom's two largest validators, which held more that one-third of the network's stake combined slowed their block emission rate (25-2-2021). This caused an offline time of seven hours according to Messari (31-3-2021).
Delegated On-Chain Vote
- Decentralisation: The platform should ultimately be run by the public: community, developers, token holders, and anyone who is a stakeholder.
- Security: Checks-and-balances should be in place to ensure that changes to governance and the underlying platform are robust, secure, and with the consent of stakeholders.
- Participation: Stakeholders can participate by being a tokenholder, running a validator node, or being a member of the moderating or technical committees.
- Efficiency: Changes that are consented to should be implemented efficiently. Rejected proposals should come at a cost, to ensure that only proposals which are likely to be implemented are considered. Hence, each proposal to change the network will require an FTM deposit.
The full proposal is available here."
In the proposal it states:
"The Fantom Foundation will initially have a key role to play, as it will nominate the first Technical Committee, the first team of Moderators and the first Review Board.
As specified in Article 5 Section 2 of the Fantom Constitution, the Fantom Foundation will also have the right to make changes to Fantom Network Rules, which include governance rules, for 6 months after mainnet launch.
The Fantom Foundation will also, for some time, have a significant influence on votes, as it will be holding a large block of FTM tokens. The Foundation will particularly use this voting power during the first year after mainnet launch to effect changes in voting parameters so that they correspond better to the actual voting and participation patterns of the Fantom network. The Foundation will then gradually refrain from exerting influence."
No clear timeline has been given for this refraining.
"The Fantom Constitution itself can only be changed by a majority vote of the Assembly, with at least 65% voting power in favour and a quorum of 50% voting power.
Proposals for emergency changes can be decided upon by the Technical Committee with a simple majority, subject to a quorum of 50%.
The Assembly will be able to veto any emergency decision via a majority vote organised by the Moderators immediately after a positive emergency vote by the Technical Committee. A veto can be obtained with a simple majority of voting power, subject to a quorum of 10% of voting power.
The voting power of an account will depend both on tokens held and on that user’s activity, with voting itself constituting one type of activity. Therefore, actively participating in the voting process will increase a user’s share of block rewards for delegated tokens. The exact parameters of how voting power is computed will be determined later.
In the future, the Fantom Network is expected to integrate with one or more SSI (Self-Sovereign Identity) platforms. Accounts that become linked to a real person via SSI will then be given a higher weight than unidentified accounts."
- Has BEP2, ERC-20 and a Native one. There is a Fantom-bridge (8-1-2020) to swap the tokens for the mainnet coin.
- Had a crowdsale and private sale.
"A total of 3.175 billion FTM was initially issued. The entirety of the supply, including staking rewards, was issued at launch.
40% was allocated to Public and Private Sale investors, including private sale bonuses. Those FTM have no vesting schedule.
15% was allocated to advisors, with a 3-months lockup
10% was allocated to the founding team. This allocation features a 24-months vesting period with monthly-cliffs
3.6% was allocated to a strategic reserve. Those FTM have no vesting schedule.
31.4% was reserved for staking rewards, to be distributed daily until 2024
Fantom's outstanding supply is fixed. The liquid supply increase displayed on the curve is the consequence of the vesting schedules detailed in the Launch section as well as the distribution of premined staking rewards. Those rewards are set to be distributed daily to validators and delegators. The daily expected distribution is set at 682,425.46 FTM, until 2024."
Binance Research has conflicting information:
- "Seed Sale tokens make up 3.15% of total token supply.
- Private Token Sale tokens make up 37.04% of total token supply.
- Public Sale tokens make up 1.57% of total token supply.
- Team is allocated 7.49% of total token supply.
- Advisors received 12% of total token supply.
- Token Reserve constitutes 6% of total token supply.
- Block Rewards is allocated 32.75% of total token supply."
- From Messari (9-3-2020): FTM tokens are intended to be used as payment for transaction fees, to stake on the network for security purposes, and to participate in on-chain governance.
FTM and FTG
- FTG is not talked about anymore but the last post (2019) asking about it concludes in that it is now phased away into the back.
- From this deep dive (6-2019):
FTM will be listed on exchanges and its value proposition is based upon the growth of the Fantom network by transaction volume.
FTG is the internal gas token, which pays for all transactions on the network and will be fixed against fiat at a rate that proves profitable for validators.
It is expected that FTG will track cloud computing and storage costs, thus its price is expected to decline over time, though this will be decided by on-chain voting.
FTG can only be bought with FTM."
- Whitepaper can be found here (28-8-2018).
- Code can be viewed here.
- Developing in Rust, Golang and Java (12-5-2019).
- Once claimed 300,000 TPS (2020) but adjusted it to 4500 TPS (2021).
How it works
- From the GoFantom website (10-3-2020): aBFT consensus, 2 sec time to finality, DAG with turing complete VM.
- Lachesis asynchronous Byzantine Fault Tolerance ('aBFT') DAG-based consensus protocol and TxFlow consensus mechanisms. Leaderless Proof of Stake (not Delegated Proof of Stake). From their own website (10-3-2020):
"'aBFT' means that transactions are confirmed as fast as possible as they enter the network, instead of waiting for previous transactions to be confirmed. Instead of centralizing all computing power and all usage on a single decentralized ledger, users of the Fantom ecosystem deploy their own independent distributed ledgers with the consensus at its core, while being able to communicate with one another.
A distributed ledger is considered to be a platform, and the consensus is considered to be a module. Users will be able to deploy their own distributed ledgers which will be powered by Lachesis aBFT and/or TxFlow, in combination with different types of middleware ranging from the Fantom SDK to the Ethereum Virtual Machine (EVM).
Lachesis aBFT is a Fantom’s core asynchronous and leaderless byzantine fault tolerant consensus protocol. It is based on principles about gossip protocols where small bits of information are propagated throughout the network rapidly. In order to make it as easy as possible to build distributed ledgers tailored to the needs of the user, we designed Lachesis aBFT to be highly adaptable and compatible with existing codebases such as Cosmos SDK and Go-Ethereum.
TxFlow is a protocol for transaction responsiveness. It is not a new consensus mechanism, but a protocol to run concurrently to consensus wherein users submit transactions and receive confirmations in real time. Regular consensus systems, such as BFT creating blocks and voting on them, are still required as a secondary—or perhaps rather primary—security mechanism. So if the transaction did not receive enough votes before the block proposal that would have included it, it will still be added."
"The Fantom OPERA Chain has three layers the Core Layer which processes transactions at scale, the OPERA Ware layer which supports Smart Contract functionality and the OPERA application layer to provide support for third party applications The OPERA Chain utilizes the Lachesis protocol which looks to create potentially infinite scalability with hundreds of thousands of transactions per second by adopting a method where a single event block verifies the previous transaction, and transactions are verified and processed asynchronously without needing approval from miners. Event blocks store information that include multiple data packages which contain transactions, Smart Contracts, historical information, reputation management and rewards.
The event block that can connect a supra-majority (greater than two thirds) among event blocks will be appointed as the Clotho and utilized for the appointment of Atropos and for the consensus of other event blocks. The Atropos constitutes the main chain and is utilized in the consensus of other event blocks.
Fantom OPERA Chain intends to use a high-level Scala-based functional programming language that compiles to smart contract bytecode on the Fantom Network. Scala has a large community of users and is known to be comparatively easy to learn. It was developed to remove the inconvenience of Java and allows developers to write organized and clean code. Scala provides both object-oriented and functional coding paradigms."
"The following are some steps for a transaction to reach finality in the Fantom network:
- When a user submits a transaction into a node, a successful submission receipt will be issued to the client as a confirmation of the submitted transaction.
- The node will batch the user submitted transactions into a new event block amended into a DAG structure of event blocks and then will broadcast the event block to all other nodes of the system. The node will send a receipt confirming that the containing event block identifier is being processed.
- When the event block is known by majority of the nodes (e.g. it becomes a Root event block), or being known by such a Root block, the node will send a confirmation that the event block is acknowledged by a majority of the nodes.
- The system will determine the condition at which a Root event block becomes a Clotho for being further acknowledged by a majority of the nodes. A confirmation is then sent to the client to indicate that the event block has come to the semi-final stage as a Clotho or being confirmed by a Clotho.
- After the Clotho stage, the network will determine the consensus timestamp for the Clotho and its dependent event blocks. Once an event block gets the final consensus timestamp, it is finalized and a final confirmation will be issued to the client that the transaction has been successfully finalized."
- For all the basic information on staking on Fantom, check this blog (22-2-2019) of them.
- From this deep dive (6-2019):
"Validator nodes require 3.175m FTM to operate and receive staking rewards and partial transaction fee. Delegators support validator nodes and receive a portions of their rewards but pay a 15% fee to the validator."
- From their blog (27-12-2019):
Nodes that are high-performing with consistent uptime earn more rewards with a higher Proof of Importance score, which measures node performance.
Validators and Delegators earn rewards after each epoch (1000 event blocks generated by the network since the previous epoch, or after 4 hours have elapsed since the previous epoch, which ever occurs first).
Rewards (consisting of both network rewards and fees) are distributed across validators and delegators, according to their Proof of Importance score, their origination score (how many transactions they originate) and, most importantly, the amount of FTM staked.
To encourage users to stake FTM, and thereby increase the security of the network, rewards are locked until the minimum staking amount of the network (starting at 80%) is reached. This minimum staking amount decreases every second, on average, 1% a week).
Rewards are locked for a 6 month period from the launch of the mainnet."
"Once you start staking, your coins aren't exactly locked, but there are some conditions.
- If you want to unstake your coins you have to wait 7 days to access them.
- Staking rewards unlock on 6/23/2020. If you unstake before this date you will lose all the staking rewards you earned.
Any rewards you earned will be burned if you unstake before rewards are unlocked."
- For more information on the staking/delegating and transaction rewards, check this blog (6-4-2019).
- As of 10-3-2020, 10.87% of FTM are staked on it's network. And 33.66% are delegated.
- Fantom's two largest validators, which held more that one-third of the network's stake combined slowed their block emission rate (25-2-2021). This caused an offline time of seven hours according to Messari (31-3-2021). This shows clear staking concentrations.
- 62% staked (21-6-2021).
- Integrates (31-3-2020) Chainlink as its oracle solution and price feed mechanism. Went live (18-8-2021).
- Band Protocol and Fantom collaborate (19-3-2020) on bringing oracles to Opera Mainnet. Update: has now been integrated (18-9-2020).
Their Other Projects
- The Xar Network is a DeFi-oriented public blockchain built using Fantom’s Lachesis and TxFlow consensus.
- From their website (10-3-2020):
"The framework for Cosmos and Fantom-based decentralized finance. Xar Network was created from a need of corporate and central banks to use blockchain technology in a private, permissioned space. As our feature set grew we noticed consistent cross-over with the decentralized finance ecosystem, so eventually the Xar toolkit grew to a full-fledged decentralized finance toolbox.
XAR Network's public chain allows you to deposit any supported digital asset, collateralize it, mint Collateralized Stable Currency Tokens (CSCTs) based on this collateral, and then use these CSCTs to stake and earn rewards. All the while maintaining ownership of your underlying collateralized asset. Staking CSDT allows you to receive rewards from the fees pool, proportional to your share of the total CSDT stakes in the network. Your rewards are paid in a stable currency token, such as CSDT (collateralized stable dollar token), not in an inflationary token as in some other networks."
- From this announcement (10-2-2020):
“We’re collaborating with the ETClabs to bring DeFi, including all aspects of our tech stack (e.g., stablecoins, lending, staking, asset issuance, collateralization, etc.) to the Xar ecosystem,” detailed Michael Chen, CMO of The Fantom Foundation.
As part of the collaboration, users can leverage the Ethereum Classic token (ETC) as collateral to mint a stablecoin on the Fantom platform akin to MakerDAO’s Dai on Ethereum. However, Xar Network’s specific design enables agnostic issuance of collateralized stablecoins outside of ETC, including any supported Collateralized Stable Currency Tokens (CSCTs) on the network.
Some of its open-source modules include collateralized loans, collateralized index tokens, liquidity pools, synthetic swaps, and protocol-level atomic swaps. Xar is compatible with Ethereum’s ERC-20 token standard and Binance Chain’s rising BEP-2 model."

- From this deep dive (6-2019):
"It is expected that FTG will track cloud computing and storage costs, thus its price is expected to decline over time, though this will be decided by on-chain voting."
- When they had their mainnet launch (27-12-2019) these were the items that were their plans for the future:
- "Remove the use of txPool for submitting transactions to the network
- Pack more transactions into event blocks
- Add moderators, who will help in the governance of the network
- Implement governance functionality to control parameters of the network
- Fix the number of parents per event block
- Research and develop new Virtual Machine, and database with our partners: the University of Sydney and Yonsei University
- Integrate Lachesis with the new Fantom Virtual Machine"
- "FTM (both unlocked and locked) as a collateral to generate stablecoins (such as fUSD, and fEUR, to begin with) and different Synthetics (Q1 and 2)
- Allow users to access these assets across a variety of different applications (ranging from finance and payment services) while utilising fast confirmation times
- Transform Go-lachesis Consensus to have Tendermint-like ABCI-compatibility: Increase compatibility with a variety of different technologies. (Q2) Expand interoperability with different chains. (Q3)
- Keep improving the consensus engine. (Q3)
- Increase number of validators to 50 (Q4)
- Increase Lachesis’s performance to 20 blocks/second, 40 txns/block on a single test network with a quorum of 30 validators (Q4)
- Establish plan for supporting hundreds of watcher nodes (Q4)
- Implement governance contract as the owner of SFC, where Fantom token holders and validators can vote on changes to the SFC (Q3)
- ETC added as collateral on Xar Network (Q2)
- Keep improving the middleware stack (Q3-4):
The current integration with the Ethereum Virtual Machine (EVM) has been incredibly useful. However, there are shortcomings:
- We have identified several scalability and security concerns due to limitations of the EVM.
- Working with universities, we aim to research and develop a new middleware stack to replace the EVM, such as a new database and interpreter, while maintaining compatibility with Solidity
Planning to have 5 minor releases a year and 3 protocol upgrades a year."
- From their explorer (10-3-2020): Low number of validators (32) with 2130 delegators (33.66% of coins are delegated, 10.87% are staked).
"The best apps for Fantom at present involve computing; other blockchains; gene splicing; protein folding; and other stuff that involves high computational power, in general. However, Andre feels that what Fantom is really built for doesn’t actually exist yet but will do moving forward."
- From an AMA (12-5-2019): "3 ~ 12 [[[Dapps]] at mainnet launch] based on current teams working on it."
- From their Twitter (21-6-2021):
- From their Twitter (2-9-2021):
"Unique addresses are at 434,000, a growth of +152,000 (54%) since August 01. In August, Fantom saw 12,000,000 tx, 40% more than in July. Fantom has 906,000,000$ in TVL, a growth of $614m (210%) month-over-month. That’s an average of 404,000 tx per day. 63% of the $FTM supply is staked, consistent over the last couple of months."
Projects that use or built on it
- BadgerDAO; planning to deploy (17-3-2021)
- Cream Finance; launched on Fantom (4-3-2021).
- Curve; deployed (11-6-2021)
- Frozen Yoghurt; Curve fork launched on Fantom (5-5-2021).

- Ethereum & Tezos and other DAG's like HashGraph, NANO and IOTA.
- From this interview (31-5-2019) with Andre Cronje:
"IOTA is a competitor but it is better suited for IOT due to the IOTA system growing faster based on the volume of transactions. In contrast, Fantom grows faster with increased computational power. Thus, there are different target markets."
"Not permissioned and network graph dependent. Can scale higher."
Pros and Cons
- Andre Cronje once said in an AMA that the team and he 'sucks' at building a wallet (12-5-2020) and therefore outsource 'all of that'.
- Has had clear staking concentrations, in one case 2 validators which held 1/3rd of all the network's stake combined, slowed down the network for seven hours (25-2-2021).
