WinteX, Free TON, Polkadot,

Polkadot is one of the most popular cryptocurrency platforms today, created by Dr. Gavin Wood as the most compatible and hyper operable for other cryptocurrencies. Here we have described this blockchain project in detail. In short, Polkadot, in fact, consists of three parts. The main network, parachains — these are other blockchains embedded in it — and bridges between them. The result of this openness was not only popularity, but also Polkadot’s entry into the top cryptocurrencies in terms of capitalization.

Starting in October 2020, a bridge between Free TON and Polkadot is being developed, which will allow holders of both cryptocurrencies to freely transfer and exchange tokens between them. It was originally planned that the development of the bridge would consist of four stages, each of which would last about a month.

It was also assumed that the resulting product would be an open access relay network. This network should act as a messaging system from one ecosystem to another. More information about the proposed architecture of the bridge can be found here.

Details About Free TON↔Polkadot Bridge

We asked Dmitry Pavlov, head of R&D at WinteX, which won the bridge design contest, about the progress of the project.

  • At what stage is the development and implementation of the bridge, when do you think it will be implemented?

At the end of 2020, we presented our roadmap for developing a bridge between the Polkadot and Free TON networks to the Free TON community. At the moment, we are finalizing the second stage of the four. We plan to complete work on the entire bridge in May 2021, but it is important to understand that its full launch depends entirely on when the parachains are launched on the Polkadot network.

  • How will this mechanism work for users?

For the user, this will be the most familiar experience if he has previously used browser wallets such as MetaMask for Ethereum. If you need to transfer tokens from FreeTON to the Polkadot network, you simply send the transaction to the Free TON network using a wallet that looks like a browser extension, and receive them to your address in Polkadot. In the opposite direction in the same way, but using a similar extension, for example polkadot{.js}, you send a transaction to the Polkadot network and receive tokens to the Free TON address. The Broxus team has already demonstrated how this works using the example of the Ethereum↔Free TON bridge.

  • What factors could attract Polkadot asset holders to take advantage of the Free TON bridge?

We believe that the Free TON ecosystem, due to the appearance of DeFi projects in it, can be attractive to holders of various assets. Including DOT owners.

  • How is bridge safety ensured? Who and under what conditions will be engaged in relaying?

Security is ensured by voting for the transmission of a message by a distributed relay network. Through voting, they reach consensus among themselves on whether the message is false or true. To eliminate the possibility of voting multiple times, we introduce mechanisms such as staking, slashing and lottery using VRF (verifiable random function).Staking is necessary in order for the relayer to have an economic incentive to behave correctly in the network, otherwise the rest of the relayers will punish him through the slashing mechanism, in other words, the relayer will be fined for incorrect behavior. At the same time, in order to avoid the possibility of collusion, those who vote for each individual message transmitted on the network are selected randomly through a lottery. To do this, we use the verifiable random function mechanism, successfully tested by the Polkadot network, which allows us to get a random number with the correctness verification of its calculation.

We finished about the whip, now to the gingerbread. Relayers will be rewarded for their work. This reward will come in the form of a commission from the bridge users. For each message, the user pays a small commission, which is divided between the relayers who voted for him. We plan to attract people and teams from the Free TON community, as well as external players such as funds and exchanges, to the relay network.

____________________

As we can conclude, the construction of the bridge is a long process that has been going on for the fourth month, and the degree of its implementation is still close to the middle. The result should be the ability to tokenize another blockchain on Free TON after Ethereum — and these are exactly the opportunities that should make up the advantage of Free TON.
