Scalable smart contracts interfacing with real-world data

æternity’s blockchain focuses on increasing scalability of smart contract and DApps by moving smart contracts off-chain in private state channels between parties. More notably, the blockchain is supported by a decentralized oracle machine connecting data from outside sources for usage in the smart contract. In addition to usage of prediction markets for various voting and verification purposes, these main features is where æternity (AE) stand out from the like of other blockchain platforms.

Process of Securing and Using the AE Wallet: What is your feedback?

task  
Hello Crowdholders,    Thanks for your input on the last task. You can check out the ranking results here, including the top 5 winners who will receive the Ledger Nano S.    There was a lot of fascinating ideas that will help in the future to identify use cases, so kudos!   For some of you who participated in the last task, you have already created an AE wallet. In this task, we would like to hear your feedback on the flow.    --------------------------------------   Once you go to https://base.aepps.com/ you are in the AE wallet eco-system. Below is a screenshot of the view you will see when the wallet loads on mobile and on Desktop.                                                          Your job for this task:    Go through the process of setting up your wallet to make sure you are secure. This task will not explain how to do it, quite the contrary, instead you must do it yourself and give feedback.    Some questions to consider:    Did you accomplish making a secure wallet, is it understandable? Do you feel comfortable using the interface? Do you have any constructive criticism? What is missing and what would you improve?   Previous task participants have already attempted setting up the wallet, so feel free to recall and play with the interface.    Cheers! Please be honest, as thoughtful feedback is welcomed!    Important note: As AE is not yet integrated with CH, make sure to place your public key and CH username in the Survey to receive the AE token rewards for this task.

Introducing æternity (AE)

task  
  æternity’s blockchain focuses on increasing scalability of smart contracts and DApps by moving smart contracts off-chain in private state channels between parties. More notably, the blockchain is supported by a decentralized oracle machine connecting data from outside sources for usage in the smart contract. In addition to usage of prediction markets for various voting and verification purposes, these main features are where æternity (AE) stands out from other blockchain platforms.    So how does it work? State Channels:  Known as their State Channel solution (communication between parties in a smart contract) AE allows the communication off chain and only connects to the blockchain for actions of adjudication or transfer of value.    This is effective compared to other chains for two main reasons. Firstly, they don’t need to pay the network every time these parties compute. In addition to better privacy, the two parties in the contract only need to see the contract’s information. This brings higher scalability and privacy to the network users.    Oracle Machine    AE’s Oracle machine really has them standout and here is why. An oracle provides outside data to the blockchain, more specifically to the smart contracts. By having the oracle move data to AE’s blockchain, the data set becomes unchangeable and immutable within the contract. The oracle in fact collects centralized data and moves it to a decentralized system.     For example:    Lets say a freelance DApp using AE’s blockchain allows parties to hire content writers. The smart contract is programmed to read the oracles data to approve or disapprove a payment. The smart contract has rules for doing the job, such as, the article needs to be 800 words, uses 10 keywords for SEO purposes, and includes an image. The oracle can check if these rules were met after the article is produced and then tell the smart contract to make the payment.  Now for your task:    What’s your first impressions of AE? After seeing one example, come up with a use case idea where an oracle can be used with AE smart contracts. This will allow AE to utilize these ideas as they work closely with their Aepps (AE’s Dapps).  Top 5 voted use cases will receive a Ledger Nano S with æeternity branding from æternity blockchain.   Please make sure to create your AE wallet (browser-based wallet) or download using iOS or Android and place your AE public key, CH username and address (for potentially being top 5) in the Survey. We then will send out the tokens every two weeks for all the participants. In the future, we plan to integrate AE blockchain, so stay tuned!    We look forward to your feedback!
