Quantstamp 审核 Binance智能链

Quantstamp Announcements
September 21, 2020

Quantstamp has audited Binance Smart Chain, a blockchain that runs parallel to Binance Chain optimized for blockchain applications. 

Binance Smart Chain was created in order to incorporate DeFi into Binance’s blockchain ecosystem. Stablecoins, tokenized Bitcoin, lending pools, DEX aggregators, and other financial products are driving DeFi’s growth, which is approaching 10 billion USD worth of assets managed by these protocols. Binance intends to incorporate these applications into Binance Smart Chain to further contribute to this growth.

This development also comes at a timely moment due to high Ethereum gas fees. Individuals with relatively small holdings of digital assets are being priced out from participating in DeFi. This has the potential to entice users with modest funds to use DeFi applications on Binance Smart Chain.

A user paid $271.17 USD worth of ether to withdraw LINK from yEarn. 

Binance has also made it enticing for Ethereum developers to develop on Binance Smart Chain by maximizing its compatibility with Ethereum. Binance Smart Chain is: 

Instead of running smart contract applications directly on Binance Chain, Binance decided to create a parallel blockchain. This allowed Binance Chain to remain optimized for its primary use case, serving as a decentralized exchange.

Binance Smart Chain uses Proof-of-Stake Authority to achieve consensus. 21 nodes validate transactions on the network at a time. Every 24 hours, the validator set is updated based on who stakes the most BNB tokens. The validator set is managed by the Binance Chain similar to how the ETH 2.0 Beacon Chain intends to manage the validator sets for shard blockchains. 

Quantstamp’s audit included Binance Smart Chain’s consensus mechanism, the relayers that manage cross-chain communication between Binance Chain and Binance Smart Chain, and genesis contracts. Quantstamp has also audited a number of other Layer 1 protocols including ETH2.0, Avalanche, and Cardano.

Binance没有直接在Binance Chain上运行智能合约应用,而是决定创建一个平行区块链。这使得Binance Chain能够针对其主要用例保持优化,作为一个去中心化的交易所。

Binance智能链使用利益证明授权来实现共识。每次有21个节点对网络上的交易进行验证。每隔24小时,根据谁押注的BNB代币最多,更新验证器集。验证器集由Binance链管理,类似于ETH 2.0烽火链打算如何管理碎片区块链的验证器集。 

Quantstamp'的审计内容包括Binance智能链的共识机制、管理Binance链和Binance智能链之间跨链通信的中继器以及genesis合约。Quantstamp 还审计了其他一些第一层协议,包括ETH2.0、Avalanche和Cardano。
