「Smart Contract」

03. Moonbeam Network

Moonbeam is a developer-oriented blockchain that strives to provide compatibility with the existing Ethereum developer toolchain and network. It does this by providing a full EVM implementation, a Web3-compatible API, and bridges that connect Moonbeam to existing Ethereum networks. This allows developers to deploy existing Solidity smart contracts and DApp frontends to Moonbeam with minimal changes.

Moonbeam will also be a parachain on the Polkadot network. That means it will get shared security from the Polkadot relay chain and will be able to integrate with other chains that are connected to Polkadot (once that functionality is available on Polkadot).

Moonbeam achieves these goals with the following key features:

  • Decentralized and Permissionless, providing a base requirement for censorship resistance and support for many existing and future DApp use cases.
  • Contains a Full EVM Implementation, enabling Solidity-based smart contracts to be migrated with minimal change and with expected execution results.
  • Implements the Web3 RPC API so that existing DApp front-ends can be migrated with minimal change required, and so existing Ethereum-based tools, such as Truffle, Remix, and MetaMask, can be used without modification against Moonbeam.
  • Compatible with the Substrate Ecosystem Toolset , including block explorers, front-end development libraries, and wallets, allowing developers and users to use the right tool for what they are trying to accomplish.
  • Native Cross-Chain Integration via the Polkadot network and via token bridges, which allows for token movement, state visibility, and message passing with Ethereum and other chains.
  • On-Chain Governance to allow stakeholders to quickly and forklessly evolve the base protocol according to developer and community needs.

Important Technological Improvement and Advances

Released Moonbeam v0.27.1

This client solves an issue in block synchronization introduced in v0.27.0. Target: Collators and RPC

Released Runtime 1901

This runtime fixes a small bug preventing accessing some of the XC20 precompile methods

Changes: Adds missing ‘view’ modifiers in XC20 precompile (#1900)

Moonbeam v0.27.0

This current client version contains a database migration, which will happen at the first launch of this client. It will take between 5 and 10 minutes .

This database migration, once executed, cannot be reverted, so it is not possible to run Moonbeam client v0.26.1 after.

It is highly suggested to perform a snapshot before applying the new client.

This migration is not compatible with parity-db, it will require re-syncing from scratch.

Breaking changes: CLI parameters — keep-blocks and — pruning changed to become — block-pruning (default: all) and state-pruning (default: 256) ( paritytech/substrate#11934)

Runtime 1900

Breaking Changes: Pallet parachain_staking genesis has changed to better reflect storage items (#1798)

[Client/Tools] Weights are now a struct instead of a u64 (paritytech/substrate#12138)

[Client/Tools] pays_fee is now properly recorded and reflected in APIs. Some extrinsics (including Ethereum txns) and inherents will now correctly report pays_fee: No whereas they incorrectly reported Yes previously. (paritytech/substrate#11849)

[XCM] Instruction weights has been changed in moonbase alpha (only).

parachainStaking.delegate is being deprecated in favor of delegateWithAutoCompound

parachainStaking. AtStake storage item structure has changed (see #1828)

Technical Solutions Discussion

Way the calls in pallet-parachain-staking need the count? #1917

Update substrate/polkadot from v0.9.29 to v0.9.30 #1874

07. OAK Network

OAK (On-chain Autonomous Kernel) Network is a blockchain automation hub for DeFi and payments built on Parity Substrate with a first of it’s kind event-driven execution model. This model enables transactions to be triggered by event signals such as time, price, and smart contract state changes. Importantly, this differs from traditional architectures utilized by Ethereum, Bitcoin, and other popular chains where multiple transactions require repeated private key signing. With this novel design, OAK can empower any connected blockchain with autonomous functionality unleashing endless potential for our partners.

By offering on-chain automation not possible today such as advanced order execution for AMM DEXs and recurring payments, we aim to be a top tier utility solution across protocols.

Important Technological Improvement and Advances

  • Reconciled OAK crowdloan contribution data from OAK, Bifrost and Parallel websites and published Check Reward page(https://oak.tech/oak/check-reward/)
  • Fixed a problem where Bifrost users didn’t receive the correct Turing Bonus crowdloan reward.
  • Auto-compound XCM integration with MangataX DEX entered the testing stage! This will be the first XCM functional call use case in the Kusama ecosystem.
  • Created a dev Docker image with sudo and dev-queue features enabled for developers to easily test OAK blockchain.
  • Updated oak.js Javascript SDK(Github repo) to include the latest Dynamic Dispatch demo and tests.

08. Darwinia Network

Darwinia Network is a cross-chain messaging infrastructure, which provides a light client-based, programmable, universal cross-chain messaging network for decentralized applications. Now, we’ve successfully used Darwinia’s light-client cross-chain messaging protocol(LCMP) to bridge cross-chain messages between substrate-based chains, and even between substrate-based chains and EVM chains, meanwhile, Darwinia provides developers with an SDK, so they can easily integrate cross-chain capabilities into their Dapps. This will have profound implications for cross-chain interoperability, and Darwinia as a cross-chain messaging infrastructure will facilitate the building of a hybrid cross-chain network for Polkadot.

09. Phala Network

Phala Network is a Web3.0 computing cloud that supports data privacy while remaining trustless. Unlike centralized cloud service, Phala doesn’t own any server or data center. Anyone can provide permissionless servers into Phala Network, and because of a clever combination of blockchain and trusted execution environments (TEE), we can make sure the servers can’t be evil even when they are in an edge network situation. Together, this creates the infrastructure for a powerful, secure, and scalable trustless computing cloud.
