Facing the decision of which blockchain to build on is among the most challenging dilemmas for developers. Various factors, including the security of the underlying chain, cost, and its throughput, play a crucial role in influencing this decision. With the proliferation of blockchains, it has become evident that no single chain can dominate them all. Thus, the notion of interoperability has gained significance. Interoperability entails the capacity for users to engage in transactions across multiple chains, resulting in increased liquidity, enhanced capitalization, a larger user base, and greater innovation in use cases overall. Numerous mechanisms have endeavored to address this challenge through means such as bridges (e.g., Wormhole, Allbridge), and interoperability standards (IBC). However, these initiatives still grapple with problems like centralization, diminished user experience, the necessity for protocols to conform to specific standards, and vulnerability to exploits. Achieving genuine interoperability remains elusive at present. This is precisely where ZetaChain steps in.
ZetaChain is a Proof-of-Stake blockchain built on Cosmos SDK and Tendermint PBFT (Practical Byzantine Fault Tolerance) consensus engine. As a result, ZetaChain enjoys fast block time and instant finality. Smart contracts on ZetaChain support arbitrary logic that executes conditionally on external chain events, and can directly update external chain states via its TSS (Threshold Signature Scheme) signed transactions. ZetaChain thereby enables omnichain dApps that interact with different blockchains natively and directly without wrapping or bridging any assets. Unlike Ethereum where a smart contract can be trusted to manage assets according to predetermined rules, except on ZetaChain, a smart contract can leverage and manage assets on any connected blockchain.
If you've ever explored bridging or engaging in cross-chain transactions, you've probably encountered the challenge of true interoperability. Blockchains usually operate as closed systems, limiting transactions to the state of their respective blockchain. External information integration into the blockchain without a trusted third party, like an oracle, is not reliably achievable. For transactions that span multiple blockchains, reliance on a trusted intermediary, often a CEX (centralized exchange), is currently necessary. Consequently, there's a lack of a decentralized, permissionless, and public service enabling generic atomic transactions involving multiple blockchains. Even platforms like Cosmos, while enabling the creation of interoperable blockchains, require additional bridging mechanisms to connect with chains beyond the IBC ecosystem.
ZetaChain aims to solves this problem of partial interoperability.
In this section, we break down the different architectural elements of ZetaChain and its roles.
Validators : ZetaChain uses the Tendermint consensus engine, each validator node can vote on block proposals with voting power proportional to the staking coins (ZETA) bonded. We cover more about the ZETA coin below. Just like other chains, validators need to be online all the time, ready to participate in the constantly growing block production. In exchange for their service, validators will receive block rewards, and potentially other rewards such as gas fees or processing fees, proportional to their bonded staking coins. Contained within each validator is the ZetaCore and ZetaClient. ZetaCore is responsible for producing the blockchain and maintaining the replicated state machine. ZetaClient is responsible for observing events on external chains and signing outbound transactions. ZetaCore and ZetaClient are bundled together and run by node operators. Anyone can become a node operator to participate in validation provided that enough ZETA are staked. Chorus One is one of the node operators and you can stake your ZETA with us to ensure high rewards backed by robust security.
Observers: Observers are tasked with monitoring external chains for relevant transactions. This observer system is segmented into two key roles: sequencers and verifiers. The sequencer's responsibility is to identify relevant external transactions, events, and states, reporting them to the verifiers. The verifiers verify and vote on ZetaChain to reach consensus. The sequencer does not need to be trusted, but at least one honest sequencer is needed for liveness.
Signers: ZetaChain possesses a set of standard ECDSA/EdDSA keys that facilitate authenticated interactions with external chains. To prevent any single entity or a small fraction of nodes from having the ability to sign messages on behalf of ZetaChain on external chains, these keys are distributed across various signers to ensure that only a supermajority of them can sign on behalf of ZetaChain and it employs bonded stakes and a system of positive and negative incentives to ensure economic safety.
In practice, all above roles (except sequencer) are collocated in the same computer node, sharing software and credentials such as validator keys and bonded stakes and the associated rewards/slashing.
ZETA token is a multi-chain utility token that play various roles like:
Total initial supply: 2,100,000,000 (two billion, one hundred million)
Inflation: 10% of the total supply (210m ZETA) is allocated to the initial emissions pool on ZetaChain. This pool allows for block rewards targeted to sustain and secure the network over the first 4 years of network growth. After this pool is depleted, the protocol will introduce a planned 2.5% inflation through validator rewards, separate from the emission curve. More information here.
As we’ve seen above, ZetaChain promotes true interoperability between different blockchains and has a unique mechanism to facilitate that. There’s no disagreement over the fact that we’ll have dozens of chains with their own use-cases and the current interoperability solutions do not provide a great user experience or efficient capital flow. We’re proud to be steadfast supporters of ZetaChain and the Cosmos ecosystem in general and look forward to the variety of applications that ZetaChain can enable. From multi-chain NFTs to omnichain DeFi, the possibilities are endless.
