AdEx Integrating Chainlink Oracles for Validator Uptime Verification and Writer Staking | by AdEx | The AdEx Weblog | Aug, 2020


We’re thrilled to announce that we’re integrating Chainlink’s market-leading decentralized oracle community to additional improve the companies out there via the AdEx staking portal. Chainlink is a confirmed oracle answer that may present Adex customers with robust safety and reliability ensures when figuring out the uptime of validators and proving possession of writer domains.

In case you have been following us, you realize that AdEx is an promoting community with no intermediaries, which ensures much less fraud, and with no cookies or monitoring. It’s constructed on fee channels that run on the Ethereum blockchain, and as of mid 2020, we’re the most important fee channel community when it comes to complete transactions processed.

Whereas AdEx relies upon closely on actual world information corresponding to area possession, web site content material, and categorization, and so on., many of the heavy lifting is finished off-chain due to the fee channel system OUTPACE.

Nevertheless, there’s part of the AdEx ecosystem that is dependent upon exterior information being out there on-chain fully: the staking module. There, our native ADX token is staked to make sure that the advert platform runs easily — it’s carried out to guard it from varied occasions corresponding to validators going offline or publishers shedding their domains. An necessary a part of this staking module is slashing — taking away a portion of staked tokens to punish the incidence of such occasions.

As a result of these oracles type the spine of our crypto-economic incentive mannequin, we will probably be utilizing Chainlink’s oracle community to confirm slashing circumstances for enhanced safety and decentralization. Chainlink has a big assortment of safe node operators run by main DevOps groups, and gives a decentralized structure so customers receive excessive availability and manipulation resistant enforcement of staking circumstances. Moreover, the pliability of their infrastructure permits us to get information from any off-chain supply for use for on-chain verification.

“The AdEx staking module is an integral a part of our advert platform, and it additionally has a secondary DeFi perform: it permits ADX token holders to take part in our ecosystem and earn rewards,” mentioned Ivo Georgiev, CEO of AdEx Community.

“This is the reason we would have liked to pick out an oracle supplier that’s dependable, reliable, and safe. Because the trade customary that has confirmed to safe practically a billion {dollars} in worth, Chainlink was the apparent selection,” Georgiev added.

Validators on the AdEx platform have the important function of confirming impression high quality after which distributing funds through fee channels. They’re required to run 24/7 — if a validator goes offline, all advert campaigns processed by it are briefly frozen till the validator is again up.

To disincentivize this habits, every validator has a pool of ADX tokens staked in opposition to it — these point out the trustworthiness of the actual validator. The charges that the validator collects are distributed proportionally to the stakers on this pool, however the stake can also be slashed in case of a service disruption.

Chainlink oracles will probably be used to confirm that validators have skilled downtime, and subsequently set off a slashing penalty to the staked ADX tokens. Sooner or later, it can work along side our upcoming Registry system constructed on Substrate/Polkadot.

Along with utilizing ADX tokens for validator staking, we’re planning so as to add a brand new performance to our staking portal in This fall of 2020: writer staking. With this function, a writer will be capable of stake ADX tokens to extend their status inside the AdEx platform. The extra ADX they stake, the extra assurance we’ve got their visitors is of top of the range.

On this occasion, slashing can be used as a penalty in opposition to publishers for shedding the possession of their area title, which often signifies they’re now not sustaining this web site, or worse — the web site has been hijacked. This function is especially aimed in the direction of crypto publishers, permitting them a approach to show trustworthiness through financial incentives.

For this integration, we will probably be utilizing Chainlink’s oracles to request and obtain information as a way to confirm the writer’s area possession by calling into Cloudflare’s DNS over HTTPS. This may permit for a trustless approach to confirm writer possession, in addition to allow computerized slashing within the occasion of area loss.

These use instances — deploying oracles to make sure validator uptime in addition to confirm web site possession — are among the many first of their sort. We consider they’re robust steps in the direction of revolutionizing the web advert house.

If you happen to’re a developer and wish to join your good contract to off-chain information and methods, go to the developer documentation and be a part of the technical dialogue on Discord. If you wish to schedule a name to debate the combination extra in-depth, attain out right here.

Chainlink is an open-source blockchain abstraction layer for constructing and working decentralized oracle networks that give good contracts on any blockchain entry to safe and dependable information inputs and outputs. It gives oracles to main DeFi purposes like Synthetix, Aave, and Kyber Community; quite a few blockchains corresponding to Ethereum, Polkadot, and Tezos; in addition to giant enterprises together with Google, Oracle, and SWIFT.
