Ankr supports the Ethereum 2.0 deposit contract | by Ankr | Ankr | Nov, 2020 | Medium Ankr supports the Ethereum 2.0 deposit contract Ankr Follow Nov 17 · 3 min read As everyone knows now, Ethereum 2 phase 0 is imminent. One key step for this to happen is for the community to agree upon a canonical deposit contract address to kickstart the Genesis process. In order to agree upon this, it requires numerous third parties to check the contract and confirm approval that everything is correct. The more third parties carry out this https://medium.com/ankr-network/ankr-supports-the-ethereum-2-0-deposit-contract-e4787c819ed3 1/4 2020. 11. 18. Ankr supports the Ethereum 2.0 deposit contract | by Ankr | Ankr | Nov, 2020 | Medium validation, the greater the confidence instilled in the community that the address is valid and correct. This article represents Ankr’s approval of the contract address, resulting from our own verification carried out in accordance with the steps described by other community members. We arrived at this decision after independently verifying that the bytecode deployed at the contract address is exactly the same as what we could reproduce by compiling the contract’s Solidity source code in a local build. We are publishing this important announcement to notify that we are joining other members of the Ethereum community to support the use of this ETH2.0 deposit contract address for the genesis process and beyond. Independent Verification In accordance with the same steps described by the Status and Nimbus teams in their own declaration of support, Ankr carried out these same steps for our validation process. Thanks to the Status and Nimbus projects for documenting the validation steps described below: The contract at the above address was created at timestamp Oct-14–2020 09:22:52 AM +UTC as per Etherscan by a transaction with hash 0xe75fb554e433e03763a1560646ee22dcb74e5274b34c5ad644e7c0f619a7e1d0. The contract source code has been verified on Etherscan where it notes that the contract was compiled using Solidity compiler version v0.6.11+commit.5ef660b1 and optimization enabled with 5000000 runs. The following steps outline our verification process: 1. We obtained the bytecode at this address on the Ethereum blockchain using the eth_getCode method (via Infura). 2. We cloned the eth2.0-specs repository from https://github.com/ethereum/eth2.0- specs and followed the compilation instructions for the deposit contract. https://medium.com/ankr-network/ankr-supports-the-ethereum-2-0-deposit-contract-e4787c819ed3 2/4 2020. 11. 18. Ankr supports the Ethereum 2.0 deposit contract | by Ankr | Ankr | Nov, 2020 | Medium 3. We downloaded Solidity compiler version v0.6.11+commit.5ef660b1 for Linux from here. 4. We compiled deposit_contract.sol in the eth2.0-specs repository with this command: solc — optimize — optimize-runs 5000000 — metadata-literal — bin-runtime deposit_contract.sol which gave us the runtime bytecode for this contract. 5. We compared the bytecode we obtained in Step (1) to the one in Step (4) and found them to be the same. Conclusion The critical Ethereum 2.0 deposit contract (which was originally written in Vyper) was re-written in Solidity, reviewed by Solidity experts and then formally verified by Runtime Verification as explained in this blog post by Ethereum Foundation. It has now been deployed on the mainnet at address 0x00000000219ab540356cbb839cbe05303d7705fa. The Ankr team therefore supports the contract deployed at this address to be the canonical deposit contract for Eth2.

Web 3.0 Bootcamp is a joint venture to accelerate blockchain projects in Asia. These teams will participate in comprehensive training and incubation of Substrate technology and the Polkadot network, to build the future of Web3. The Web 3.0 Bootcamp opening ceremony will be held on May 7th; the program commences the following week and runs for six months. A three-month acceleration phase will be followed by a three-month Proof of Concept (PoC) phase. In the acceleration phase, teams will enhance their knowledge of basic company management, general blockchain technology, and advanced Polkadot/Substrate knowledge through a series of lectures. Completion of team projects is the focus of the PoC phase, as the teams work with Wanxiang blockchain ecosystem partners to develop and launch their applications. Du Yu, the Vice General Manager of Shanghai Wanxiang Blockchain Inc., the General Director of Wanxiang Blockchain Labs and New Chainbase, and who is a Web 3.0 Bootcamp committee member, said: “As one of the first professional institutions promoting blockchain technology and industries in China, Wanxiang will provide comprehensive support for the participating teams in technology, product, fundraising and connect them to Web 3.0 ecosystem partners.

  • a Protocol for Decentralized Proof-Of-Stake Infrastructure
    Stkr // A protocol for decentralized proof-of-stake infrastructure By Ankr // Version 1.0.0 BY ANKR Abstract Stkr is a decentralized proof-of-stake (PoS) based infrastructure that creates a global market for computational power and storage. These resources can be combined and used to carry out any predefined task that requires any capacity (i.e., processing power, storage, and bandwidth). Unfortunately, today such resources are provided by either closed networks or central cloud providers. By using a peer-2-peer mesh network, the Stkr infrastructure offers a practical, immediately viable alternative that can enable direct payments using ANKR tokens on Ethereum between users (also called “requesters”) and providers of those resources in an efficient, environment friendly, and competitive market. For the initial release (MVP), the infrastructure will utilize Ethereum 2.0 (e.g., full nodes, wallet providers, exchanges) for staking, but the mission is to expand to all other significant blockchain platforms as well as conventional systems. Using this approach, the infrastructure allows users to earn staking rewards based on their ETH and ANKR holdings without having to maintain an extensive staking infrastructure. The Stkr infrastructure enables requesters to run nodes for different protocols, without the need to study any technical documentation or requiring any technical knowledge. Just plug and play! Further, this platform has a great potential to create a comprehensive marketplace that fulfills the needs of cloud providers and staking enthusiasts.
