In general, blockchains are incompatible with each other; that is, data and assets from one blockchain cannot be moved to another. Many projects have solved this problem by creating cryptocurrency cross-chain bridges to simplify asset transfers. However, bridges are not a universal solution because they connect only certain blockchains.
For example, if a bridge is created between the BNB and SOL, it cannot be used to move assets from the SOL to the ETH. In addition, the bridge can only be used by the owners of crypto wallets that are compatible with this particular bridge.
What is a Crypto’s bridge?
A cryptocurrency bridge is a protocol that allows two or more blockchains to interact and exchange data. It connects different blockchains, allowing users of one network to carry out activities in another and use their assets outside native chains.
Blockchains have different tokens, consensus mechanisms, communities, and management models. Cryptocurrency bridges ensure the compatibility of blockchains, allowing the transfer of data and cryptocurrency assets between different chains.
Bridges also allow blockchains to take advantage of each other. For example, Bitcoin does not need to rebuild its blockchain to include smart contracts because this gap can be filled with the help of other networks.
Bridges are also actively used by developers for communication and collaboration, regardless of the network in which they are working. In this manner, protocols can seamlessly interact and take advantage of each other’s advantages and functions.
Usually, cryptocurrency bridges transfer tokens from one network to another by wrapping, that is, creating wrapped versions that lock the original token in a smart contract and create an equivalent number of wrapped tokens, such as WSOL for SOL or WBNB for BNB.
In addition to bridges, there are other technologies aimed at improving the compatibility of the cryptocurrency ecosystem. For example, zero-level protocols have been used. Level Zero offers blockchains a common base layer for developing new functions on top of it. Such blockchains do not require bridges because each network built on top of the zero layer is initially compatible with the others.
BNB and Solana Ecosystems
The Binance Smart Chain (BSC) is an EVM-compatible blockchain supported by Binance, one of the world’s largest cryptocurrency exchanges.
BSC was designed as a faster and cheaper alternative to Ethereum and scales, primarily because of a more centralized consensus and a larger block size.
The network’s native asset (BNB) is also the currency of the Binance Chain, a separate blockchain launched by the Binance team. BNB holders have the opportunity to trade on Binance with a reduced commission. Binance also regularly buys and burns the BNB in proportion to the trading volume on the exchange.
In contrast, Solana is a network that focuses on fast speeds and high throughput using the new Proof of History (PoH) algorithm, which complements PoS and allows blocks to be formed in 0.4 seconds.
Because of the low latency, the network quickly gained popularity, as users could access a wide range of dApps, for the most part, equivalent to applications in Ethereum, but without high fees or a long wait for confirmation.
However, high speed is expensive — expensive hardware is required to run a Solana node, as a result of which chain auditing becomes too costly or impossible for the average user. In addition, given that the network was launched relatively recently, users who choose Solana are stepping into a less-explored territory.
Compatibility Problem Between BNB and Solana
Despite their shared goals of enabling the creation of DApps and facilitating asset trading, the BNB and Solana use different consensus mechanisms and have distinct network architectures. BSC uses a Proof of Staked Authority (PoSA) consensus mechanism, while Solana uses a Proof-of-History (PoH) consensus mechanism.
These differences can make it challenging to transfer assets between two networks. Moreover, the lack of interoperability between different blockchain networks can lead to issues, such as fragmented liquidity and limited access to various DApps. Cross-chain bridges also play a crucial role in this process.
How Cross-chain Bridges Enable Interoperability between BNB and Solana
A blockchain bridge is an interaction protocol that enables users to swiftly and conveniently transfer tokens between different networks that are not otherwise interconnected.
In the case of BNB and Solana, a cross-chain bridge can be used to transfer BNB tokens to the Solana network and vice versa. These bridges operate by creating a “wrapped” version of the token on the destination network. For example, if a user wants to transfer BNB tokens to the Solana network, a wrapped version of BNB (wBNB) is created on the Solana network. The user can then trade the wBNB on the Solana network as if it were a regular BNB.
Conclusion
Specialized bridging protocols are used to bridge the Binance Smart Chain (BNB) and Solana. These protocols allow assets to cross the boundaries of different blockchains, thereby ensuring interoperability between the two ecosystems.
Thus, the bridging process between BNB and Solana is carried out using bridging protocols that ensure the security and efficiency of the asset movement between these two blockchains.
