Navigating the Future: A Glimpse into Binance Chain’s Evolution
Embarking on a journey through the intricate landscape of blockchain technology, Binance Chain (BC) stands as a beacon of innovation and adaptability. With its dual-chain strategy, BC has revolutionized the realm of decentralized finance (DeFi) by seamlessly merging lightning-fast transactions with unparalleled programmability. However, this is merely the genesis of BC’s narrative, with its evolution showing no signs of slowing down.
In this article, we’ll delve into the promising outlook for Binance Chain, exploring its ongoing development and the avenues it’s poised to explore. From tailored digital asset models to enhanced data feeds and seamless integration with Ethereum and beyond, BC is poised to redefine the boundaries of possibility within the blockchain ecosystem. Join us as we navigate the future of Binance Chain and uncover the exciting prospects that lie ahead.
The Quest for Flexibility and Performance
Since its launch in April 2019, Binance Chain has proven itself with remarkable speed and impressive throughput. At its core, the Binance Chain’s flagship decentralized application (dApp), BNB DEX, has exemplified swift, high-capacity trading, effortlessly managing millions in trading volume within tight timeframes.
However, balancing flexibility and usability with performance presents a challenge. While Binance Chain aims to offer a user-friendly platform for digital asset issuance and trading, this focus has its limitations. Among the most sought-after features is programmable extendibility, notably Smart Contract and Virtual Machine capabilities. Users and asset issuers seek to integrate decentralized features and community governance mechanisms, yet these additions are not currently supported.
Integrating Smart Contracts onto Binance Chain presents a complex decision. While it holds the promise of expanded functionality, there are concerns. Smart Contracts could potentially slow down exchange processes and introduce unpredictability into trading. One proposed solution involves introducing a new Virtual Machine specification based on Tendermint, aligned with Binance Chain’s existing consensus protocol. However, such changes would necessitate increased learning curves for existing dApp communities, potentially deterring adoption.
To address these challenges, we advocate for the creation of a parallel blockchain alongside Binance Chain. This parallel blockchain would preserve the high-performance capabilities of the native DEX blockchain while accommodating Smart Contract functionality, offering users the best of both worlds.
Demystifying Binance Smart Chain’s Consensus and Reward Mechanisms
Consensus and Validator Quorum:
Binance Smart Chain (BSC) employs a unique consensus mechanism that blends Delegated Proof of Stake (DPoS) with Proof of Authority (PoA), achieving fast transaction times and secure validation.
Proof of Staked Authority (PoSA):
Traditionally, decentralized networks rely on Proof of Work (PoW) for security. However, PoW’s energy consumption and scalability limitations prompted the exploration of alternatives like PoA and DPoS. PoA, used in networks like Ethereum’s testnet and mainnet, offers improved efficiency but faces criticism for centralization. To address this, DPoS, utilized by EOS and Lisk, empowers token holders to elect validators, enhancing decentralization.
BSC innovatively combines DPoS and PoA, ensuring:
1. Limited set of validators.
2. Validators produce blocks in a PoA manner, akin to Ethereum’s Clique consensus.
3. Validator set election based on stake-based governance.
Validator Quorum:
Initially, a select group of trusted nodes forms the Validator Set, with candidates competing for election once block production begins. The top 21 staked nodes become validators, with elections recurring every 24 hours. BNB serves as the staking token.
To ensure compatibility with Ethereum and facilitate future consensus upgrades, BSC delegates staking management to Beacon Chain (BC), issuing cross-chain messages for validator set updates. Validators periodically check for these updates, adjusting the set accordingly.
Security and Finality:
While PoA networks generally operate securely with honest validators, there’s still a risk of attacks by Byzantine validators. To mitigate this, users are advised to wait for blocks sealed by over two-thirds plus one validators, akin to BC’s security level. Additionally, BSC introduces Slashing logic to penalize malicious validators swiftly.
Reward:
Validators receive transaction fees in BNB as rewards, promoting network security and integrity. Delegators stake BNB with validators, who decide reward distribution to attract staking. Despite variations in stake, rational delegators tend to choose validators with lower stakes to avoid slashable risks, preventing stake concentration issues seen on other networks. Portions of gas fees also reward relayers for facilitating cross-chain communication.
Example: Think of BSC’s consensus and reward mechanisms as a well-oiled machine, with validators and delegators working in harmony to secure and maintain the network. Just as in a democratic society, validators are elected based on stakeholder votes, ensuring fairness and decentralization. Meanwhile, rewards incentivize active participation and contribute to the network’s growth and stability.
Understanding Binance Chain’s Token Economy and Interoperability
Token Economy:
Binance Chain (BC) and Binance Smart Chain (BSC) share a unified token ecosystem for BNB and BEP2 tokens. This setup enables seamless bi-directional transfer of tokens between the two networks via cross-chain communication.
Native Token:
BNB serves as the native token for both BC and BSC, similar to how ETH operates on Ethereum. Apart from its use in paying fees on Beacon Chain (BC) and BNB DEX, BNB has additional utility on BSC. It’s used for deploying smart contracts, staking on selected BSC validators, and facilitating cross-chain operations.
Seed Fund:
During the genesis stage, a portion of BNB is burnt on BC and minted on BSC, forming the “Seed Fund.” This fund is distributed to initial relayers and validators on BSC to cover transaction fees during the early stages.
Token Binding:
BEP2 tokens on BC and BEP2E tokens (ERC20 compatible) on BSC can be bound together to ensure seamless circulation between the two chains. This process, known as Token Binding, associates the tokens with a corresponding contract on the opposite chain.
Procedure for Token Binding:
1. Ensure the total supply matches on both blockchains.
2. Lock tokens on BC and BSC to establish initial circulation.
3. Initiate the bind transaction on BC, which creates a cross-chain bind request package.
4. BSC relayers relay the bind request into TokenHub on BSC.
5. The TokenHub owner approves the bind request, verifying proper token attributes and lock status on both chains.
6. Upon successful approval, tokens become bound, allowing bidirectional transfer.
Example: Think of Binance Chain’s token ecosystem as a bridge connecting two islands (BC and BSC), enabling seamless travel of goods (tokens) between them. Just like a passport (Token Binding) facilitates travel between countries, Token Binding ensures tokens can freely move between BC and BSC. This streamlined process enhances interoperability and expands the utility of tokens across different blockchain networks, fostering a vibrant and interconnected ecosystem.
Exploring Binance Chain’s Cross-Chain Transfer and Communication
Cross-Chain Transfer and Communication:
Cross-chain communication is pivotal for maximizing the benefits of Binance Chain’s dual chain structure. It enables users to:
Create diverse tokenization, financial products, and digital assets on both Binance Smart Chain (BSC) and Binance Chain (BC).
Trade and circulate assets seamlessly across BSC and BC within a unified ecosystem.
Operate efficiently within a single user interface and tooling environment.
Cross-Chain Transfer:
Cross-chain transfer facilitates communication between BSC and BC. The process involves:
Locking the asset amount from source owner addresses on the transfer-out blockchain into system-controlled addresses/contracts.
Unlocking the asset amount from system-controlled addresses/contracts on the transfer-in blockchain and transferring it to target addresses.
Key aspects of cross-chain transfer include verifying:
Proper removal and locking of token assets from the source address.
Correct release and allocation of token assets on the target blockchain.
Maintenance of the total circulation of token assets across both blockchains.
Architecture:
The architecture for cross-chain communication varies between BC and BSC:
BC to BSC Architecture: BC employs the Tendermint-based blockchain with instant finality. Communication from BC to BSC is verified via an “on-chain light client” implemented through BSC smart contracts. These contracts sync BC blocking status periodically, allowing for accurate verification and execution of cross-chain transactions.
BSC to BC Architecture: BSC uses the Proof of Staked Authority consensus protocol, necessitating a different approach. Cross-chain communication requests from BSC are submitted and executed as transactions on BSC, emitting events observed and packaged by BC Oracles. Validators on BC, acting as Oracle Relayers, verify and secure these packages, ensuring their integrity.
Timeout and Error Handling:
Cross-chain communication may encounter failures, necessitating timeout and error handling mechanisms. These include:
Refunds initiated by BSC or BC in case of expected errors or system exceptions.
Timeout procedures triggered by Relayers and Oracle Relayers to mark stuck sequences as “Unexecutable” after a specified period.
Cross-Chain User Experience:
While users expect a seamless experience across both chains, complex operations are primarily handled by wallets and user interfaces. BSC and BC focus on enabling basic operations for value flow, leaving user experience enhancements to client-side tools.
Cross-Chain Contract Event (CCCE):
CCCE enables smart contracts to trigger cross-chain transactions directly. Standard operations include:
BSC to BC transfer.
Transfer on BC.
BC to BSC transfer.
IOC (Immediate-Or-Cancel) Trade Out.
Auction Trade Out.
These features extend cross-chain transfer and exchange functions to smart contracts on BSC, enhancing application scenarios and maximizing utility across both chains.
Exploring Staking and Governance on Binance Chain
Staking and Governance:
Staking and governance play crucial roles in decentralization and community participation within Binance Chain’s ecosystem. Here’s a simplified breakdown of how it works:
1. Token holders can stake their tokens or delegate them to validators.
2. Validators are selected based on the number of tokens bonded to them.
3. Validators share rewards with their delegators.
4. Validators face penalties, known as slashing, for misconduct.
5. There’s an “unbonding period” to ensure tokens remain bonded during penalty periods.
Staking on Binance Chain:
Staking on Binance Chain (BC) involves:
1. Using BNB tokens for staking.
2. Executing staking actions on BC.
3. Determining the Binance Smart Chain (BSC) validator set through a staking module on BC.
4. Distributing rewards on BC, usually around UTC 00:00 daily.
Reward Distribution:
Rewards are distributed to validators and delegators around UTC 00:00 daily. A deliberate delay is introduced to ensure fairness:
1. Blocking rewards are accumulated in a contract.
2. Rewards are transferred to custody addresses upon validator set updates in BSC.
3. Rewards for the current day are distributed on the next day (N+2 days).
Slashing:
Slashing is a form of punishment for malicious behavior. Two slashable cases include:
1. Double Sign: When a validator signs more than one block with the same height and parent block.
2. Inavailability: When a validator fails to produce blocks timely due to various reasons.
Governance Parameters:
Binance Smart Chain’s system parameters, such as slash amount and cross-chain transfer fees, are determined through a proposal-vote process by the BSC Validator Set on BC. These parameters are then implemented through cross-chain communication.
Understanding Relayers in Binance Chain’s Cross-Chain Communication
Relayers play a vital role in facilitating communication between Binance Chain (BC) and Binance Smart Chain (BSC). Let’s delve into what relayers are and how they operate:
BSC Relayers:
BSC Relayers are responsible for transferring Cross-Chain Communication Packages from BC to BSC. Here’s how they work:
1. Registration and Deposit: Relayers must register on BSC and deposit a certain amount of BNB, which is refundable. This ensures that only registered relayers can submit requests.
2. Verification and Gas Fees: The packages relayed by BSC Relayers undergo verification by the on-chain light client on BSC. Successful relay incurs gas fees on BSC. To incentivize participation, rewards are provided to relayers.
3. Incentive Structure: There are two main types of communication:
— User-triggered Operations: Users pay additional fees as relayer rewards for operations like token binding or cross-chain transfers. Rewards are shared among relayers who sync blockchain headers.
— System Synchronization: Rewards are directly paid to relayers’ accounts for tasks like delivering refund packages or synchronizing blockchain headers.
4. Preventing Monopolization: To prevent monopolization and encourage decentralization, rewards are distributed in batches, and the more packages a relayer handles, the less reward they receive per package.
Oracle Relayers:
Oracle Relayers facilitate communication from BSC to BC using an “Oracle” model. Here’s how they function:
1. Validator Responsibility: Each validator in the BSC validator set runs an Oracle Relayer. These relayers monitor blockchain state changes and submit cross-chain communication packages for voting.
2. Voting Process: Once a package is submitted, Oracle Relayers from at least ⅔ of the voting power of BC validators must vote for the changes before cross-chain actions can occur.
3. Confirmation and Fees: Oracle Relayers wait for enough blocks to confirm finality on BSC before submitting and voting for cross-chain communication packages onto BC. Cross-chain fees are distributed to BC validators along with normal blocking rewards.
4. Performance Assessment: The performance of Oracle Relayers can be assessed through recorded votes on the blockchain. Poor performers may face consequences such as reward clawbacks through future slashing logic.
In essence, relayers ensure smooth communication between Binance Chain and Binance Smart Chain, promoting interoperability and efficiency within the ecosystem.
