Скачать или смотреть An introduction to Fantom

ETH started as a vision of being a world supercomputer, leveraging the combined resources of all participants in the network-

However, ETH currently utilizes what is known as a “proof of work consensus algorithm,” which is a “synchronous” system, only allowing a single set of action to happen at once

If I wanted to say, compute 2+2, instead of being able to execute that simple calculation using only a fraction of the power of the combined super-computer network,

Because of the limitations of proof of work: the entire super-computer network must utilize its complete processing power on this, or any calculation or task given to it, until, every single actor in the network, has completed the task for themselves.

here is massive inefficiency and waste of processing power in this method, as most calculations the network is being called to do, can be solved by only a small portion of the network, freeing up the rest to focus on solving other problems simultaneously in parallel.

Seeing this problem, some of the greatest minds in consensus algorithms got together, and created Fantom's Opera Network. A decentralized world supercomputer like ETH, however this time utilizing a more advanced consensus algorithm.

Lachesis. A proof of stake, verified computing consensus algorithm that doesn't use large physical energy consumption like proof of work does. Instead of large server farms, using as much electricity as possible to be a participant in the supercomputer network, proof of stake consensus algorithms allows anybody with capital, to participate with helping secure the network by locking funds into nodes. These nodes are then chosen at random to validate the next block.

To put it more simply: under the hood, Lachesis enables many computers to behave as one.

You'll find different terminology when discussing Proof of Stake over Proof of work.

Instead of being called Miners, network participants are called validators, and new blocks aren't “mined” but rather “minted”

To become a validator node in the network, there is usually a threshold of tokens that the network requires. You can see this almost as a security deposit.

People who do not have enough capital to meet the requirements to become a full validator node themselves, can decide upon a validator they like and stake their funds in that validators' node to participate in rewards proportional to whatever they have provided, given the current APY of the network.

Verified computing, is when a participant in the network is tasked with something such as our previous 2+2 example, computes it and then produces a 'digital certificate of proof' showing that the computer calculated this successfully, so that the next participant in the network, instead of having to compute 2+2 for themselves as well, can instead just check this certificate and know it is good.



Utilizing verified computing and proof of stake consensus, Lachesis seeks to revolutionize current blockchain standards with a more decentralized and environmentally friendly alternative to current decentralized ledger technology standards such as Bitcoin or Ethereum.

Lachesis is currently the engine that powers the Opera blockchain: An Ethereum compatible blockchain that utilizes the Fantom token as the underlying gas-payment mechanism. Built in the same exact language as Ethereum, it has no trouble communicating with the Ethereum network, and developers don't need to learn anything new in order to launch decentralized applications on top of the Opera blockchain.

The Fantom Foundation has built a mutualistic symbiotic relationship between the Opera blockchain and the Ethereum blockchain. As a cross-chain ecosystem becomes further actualized, Opera utilizing Lachesis can help Ethereum scale by doing heavy computations on Opera, and bridging finalized computations back to ETH.
