BNB Beacon Chain to Undergo Scheduled Barral Hard Fork Upgrade

On April 17th, according to the official blog, the BNB Beacon Chain is expected to undergo a scheduled Barral hard fork upgrade at block height of 310182000. Based on the current block generation speed, it is expected that a hard fork will occur on April 21st at 15:00 Beijing time. All node operators on the main network must switch their software version to v0.10.10 before April 21st. In this upgrade, BEP171 will introduce several security enhancements for cross chain bridging between BNB beacon chains and BNB smart chains (BNBSmartChain). In order to further eliminate the widespread impact of potential issues in cross chain modules, BEP171 proposes the following improvements: 1. Upgrade IAVL proof validation to the ICS23 specification. 2. Apply timer locks to massive cross chain fund transfers. 3. Through forged proof detection, cross chain channels can automatically pause. In emergency situations, any verifier can suspend cross chain channels.

The BNB beacon chain is scheduled to undergo a Barral hard fork upgrade on April 21st, introducing several security enhancements across the chain

On April 17th, the official Binance blog announced that the BNB Beacon Chain will undergo a scheduled Barral hard fork upgrade at block height of 310182000. Based on the current block generation speed, it is expected that a hard fork will occur on April 21st at 15:00 Beijing time. All node operators on the main network must switch their software version to v0.10.10 before April 21st.

Introduction

The Binance Smart Chain ecosystem has been growing at an unprecedented pace. With the increasing demand for cross-chain liquidity, it is essential to ensure a secure and reliable blockchain infrastructure. The upcoming hard fork upgrade aims to address the security concerns for cross-chain bridging between the BNB beacon chain and the Binance Smart Chain (BNBSmartChain).

BEP171 for Security Enhancements

In this upgrade, BEP171 will introduce several security enhancements for cross chain bridging. BEP171 proposes the following improvements:

1. Upgrade IAVL Proof Validation to the ICS23 Specification

BEP171 upgrades the Inter-Application Communication (IACC) verification process, which is responsible for checking the validity of cross-chain messages. The IAVL proof validation is upgraded to the ICS23 specification, which introduces a more secure and efficient verification process. This upgrade will enhance the trustworthiness of the cross-chain bridging process.

2. Apply Timer locks to Massive Cross Chain Fund Transfers

In order to mitigate the risks associated with massive cross-chain fund transfers, BEP171 introduces a timer lock mechanism. This feature ensures that large amounts of funds cannot be transferred instantaneously. Instead, a predefined time delay is implemented before any transfer can be made, which reduces the likelihood of potential security breaches.

3. Automatic Cross Chain Channel Pausing Through Forged Proof Detection

The upgrade also introduces a forged proof detection mechanism that detects any suspicious activities on the cross-chain channels. The system can automatically pause cross chain channels if any abnormalities are detected, enhancing the overall security level of the cross-chain bridging process.

Conclusion

In conclusion, the Barral hard fork upgrade for the BNB beacon chain will take place on April 21st. This upgrade introduces several security enhancements to the cross-chain bridging process between the BNB beacon chain and the Binance Smart Chain. The upgraded features, such as IAVL proof validation, timer locks, and automatic cross-chain channel pausing through forged proof detection, are designed to improve the security and reliability of the blockchain infrastructure.
