Because the introduction of Bitcoin in 2009 and the explosion of innovation that adopted, the web3 business has confronted many challenges. Past coping with regulators, bettering UX, and hunting down dangerous actors, blockchain engineers proceed to deal with two main hurdles: scalability and interoperability.
Whereas many Layer 2s are working to scale Layer 1s like Bitcoin and Ethereum by bettering throughput and lowering transaction charges, protocols like Union allow each—interoperability at scale.
The necessity for blockchain interoperability
No matter your opinion on the WEF, its 2020 whitepaper on blockchain interoperability hit the nail when it acknowledged, “Organisations don’t wish to discover themselves on a blockchain platform that will restrict their choices for exterior collaboration sooner or later.”
To elaborate additional on that time, think about having a Gmail account, sending a message to a Yahoo account, and being unable to change communications. The web was capable of develop as rapidly because it did as a result of it factored in interoperability from the early days, and blockchains should do the identical.
A notable participant within the interoperability house is Cosmos, whose flagship Inter-Blockchain Communication (IBC) protocol has enabled a number of sovereign chains to attach, transact, change, swap tokens, and carry out different actions with out compromising sovereignty. Map of Zones exhibits 91 zones now linked by way of IBC transacting greater than $2.1 billion during the last 30 days in additional than 8.7 million transactions.
IBC isn’t restricted to Cosmos chains, both. The trustless interoperability protocol has broadened its scope to incorporate EVM-compatible chains equivalent to Ethereum, Polygon, and Avalanche. Nonetheless, most bridging options to date have been supplied by centralized suppliers, which means customers should belief the bridging protocol.
Constructed and backed by Composable Finance, Consensys, Tokensoft, and Polygon Labs, Union supplies a permissionless bridging protocol that connects modular blockchains and rollups trustlessly, with out relying on trusted third events, oracles, multi-signatures, or MPC, utilizing superior zero-knowledge (ZK) cryptography.
Already connecting a number of ecosystems, Union not too long ago introduced a partnership with L2 developer Polygon Labs that can faucet into Polygon’s AggLayer “to facilitate message passing and asset transfers between the Polygon ecosystem and IBC-enabled chains,” bridging two of the biggest blockchain ecosystems: Polygon and Cosmos.
Permissionlessly bridging Polygon, Cosmos, and past
Union founder and prior CTO at Composable Finance Karel Kubat informed CryptoSlate, “It’s not only a Cosmos to Polygon bridge however something that’s IBC-enabled, which incorporates Scroll, and shortly Arbitrum, Berrachain, Motion Labs, M2… They’ll construct and join into the Agglayer utilizing Union,” permissionlessly tapping into the liquidity of one of many largest blockchain Layer 1s, Ethereum.
“Proper now it’s very attention-grabbing as a result of now we have massive L1 ecosystems that actually solely have permissioned centralized bridges or one thing in between. You might want to go to the bridge supplier to get assist for a small ecosystem. What Union does, is should you’re constructing a brand new Cosmos chain or a brand new rollup that’s IBC enabled, you don’t have to go to a centralized supplier to get assist. You simply open the connection to Ethereum and also you’re finished… So we’re going fairly rapidly from a world with solely 200 to 300 ecosystems to a world with hundreds and hundreds.”
This sort of seamless interoperability isn’t doable with centralized options as a result of the “wait queue” is just too lengthy. Each chain wanting to attach must request the bridging protocol’s permission.
With Union, chains can permissionlessly open a channel with Ethereum, enabling a seamlessly interconnected future… of doubtless hundreds of thousands of chains. Karel provides the instance of dYdX, one of many largest decentralized exchanges that started as a sensible contract on Ethereum and moved ecosystems to turn out to be a sovereign Cosmos app chain.
“All of us went into crypto for sovereignty,” he says. “Any profitable sensible contract is considering going to their very own L2 or app chain.” This implies the overall addressable marketplace for Union is probably huge. “It isn’t anybody that wishes to construct a blockchain. It’s any current app on Ethereum and Solana that would profit from making this transfer.”
Union’s IBC to Polygon bridge needs to be accomplished by the top of this yr and you’ll sustain with the newest developments by following Union on X.
