Awareness and social encounters

Zaki Manian (Tendermint team) and Dean Tribble (Agoric) joined the hosts on November 5tth, 2019 to discuss Cosmos IBC and Game of Zones (GoZ). IBC enables blockchains to exchange value and data. GoZ will test and train operators of IBC with 100,000 ATOMs in rewards, likely beginning in January 2020.

Quick Takes:

  • IBC enables blockchains to exchange value & data
  • Game of Zones (GoZ) incentivizes the Cosmos community to learn to operate IBC relayers and test its functionality & security
  • Validators, wallet operators, and app developers are likely to participate
  • GoZ may begin in Dec, but likely January and last for three weeks
  • Each stage of the game will teach & reward different IBC-related operations
  • Prizes total 100,000 ATOMs, funded by the ICF, likely judged by Zaki & Dean
  • Head to this section to read about how to prepare for GoZ

The Interchain Foundation (ICF) raised $17 million in April 2017 to shepherd the development of the Cosmos network.

“To date, we still have over 1,400 BTC, over 50,000 ETH and just over 20 million ATOMs in the treasury,” ICF director Arianne Flemming says.

At today’s prices, that’s worth over $104 million. And that’s even after the nonprofit deployed $25 million in capital to fund over 50 projects.

22 Ethermint: EVM on Cosmos with Chainsafe’s Austin Abell and Gregory Markou: Chainsafe is an R&D consulting firm focused on blockchain technology. The team is building clients and applications for various blockchain projects including Ethereum, Polkadot, and Cosmos. In this interview, Brian is talking to Austin and Gregory, who have been working on the Cosmos SDK module called “Ethermint”. Ethermint is bringing the Ethereum Virtual Machine (EVM) to the Cosmos ecosystem allowing developers to launch their own blockchains with EVM support. One of the chains that is going to use the Ethermint module is Aragon Chain, which Chainsafe has also been commissioned to build. This episode dives into the design of the Cosmos SDK, challenges of building Ethermint, the report Chainsafe wrote that assisted Aragon’s choice to migrate into the Cosmos ecosystem, and much more.

23 Microtick: Price Oracles and Short-Term Options with Mark Jackson and Kent Barton: Microtick is an innovative protocol designed to foster global price agreement for any type of asset through an economic game between market makers providing quotes and traders placing bets. Microtick is a ShapeShift research project that is currently live in the form of a Cosmos SDK testnet.

In this episode, Meher and Felix are joined by Mark and Kent, who are leading Microtick’s research and development. They dive into the background of Microtick and how the project developed inside of ShapeShift. Mark and Kent explain Schelling points, how the protocol works at a high-level, the notion of a short-term options market and Microtick’s use cases, which range from Microtick as a price oracle, over Microtick as a product to hedge price exposure, to Microtick as a tool to build synthetic assets.

Aragon Chain by Colin Schwarz: ChainSafe was recently engaged by the Aragon Network (and the AA by proxy) to build Aragon Chain, an alternate chain optimized for Aragon usage. Aragon Chain will be built by implementing existing Aragon smart contracts and associated components on Ethermint, which is also being built by ChainSafe. Ethermint is a Cosmos SDK module that provides the same functionality as mainnet Ethereum. The major difference is that Ethermint features proof of stake consensus which allows for faster and cheaper transactions as well as instant finality. We wanted to take the time to write a bit about Cosmos and Ethermint and how we plan to leverage these systems to deliver a custom chain, optimized for the Aragon community.

Aragon Chain will consist of two primary components: a migration of Aragon contracts from Ethereum to Ethermint, and a bridge that facilitates the transfer of value and information between Ethereum Aragon and Aragon Chain. This means that Aragon Chain will provide the same functionality to which users are accustomed on mainnet Ethereum, with the added bonus of lower fees and faster blocktimes and transactions. Building Aragon Chain as its own Cosmos zone will also allow for a higher level of control and customization in terms of future Aragon initiatives. Aragon Chain thus represents a unique intersection of some of the most powerful and exciting technologies in the blockchain space, including Ethereum, Aragon, Cosmos and Ethermint. ChainSafe is currently in the process of creating a specification and risk assessment for Aragon Chain and will begin development before the new year.

Linked Up: Developing a blockchain-based networking game by Stoyan Dimitrov: In collaboration with the organizers of SF Blockchain Week, Eco built a Cosmos-based dApp for conference attendees to network and exchange contact information. They used the Cosmos-SDK framework to build Linked Up because of its quick development cycle and rich set of blockchain modules that they could compose to accelerate development. What began as a side project became one of the most heavily used live dApps to date.

Linked Up was designed to enable people to connect and exchange contact information in a secure and self-sovereign way. By connecting and sharing, players gained reputation points redeemable for prizes. Over the two-day conference, hundreds of attendees used Linked Up to create thousands of connections and securely share their information on-chain.

In this article the team discuss how they built Linked Up, with a focus on the architecture behind the game and development issues they encountered. They have published the source code as well, for others to improve and build upon. You can find the blockchain here and the web app here.
