# What Is ZetaChain (ZETA)?

ZetaChain is a novel L1 that has chain-agnostic interoperability built-in (EVM-compatible, Cosmos/IBC, Bitcoin, Dogecoin, Tron, etc.). Developers currently use ZetaChain’s messaging capabilities to send data and native value (without wrapping assets) between any chains. 

ZetaChain will also support native smart contracts, which let developers build omnichain dApps that orchestrate funds across chains from a single contract.

# Who Are the Founders of ZetaChain?

ZetaChain’s founder was an early Coinbase employee and one of the creators of Basic Attention Token (BAT). Investors include all major market makers, top exchanges, early Coinbase and Binance employees including Dan Romero, Sam Rosenblum, and John Yi, as well as major contributors to some of the industry’s most widely adopted protocols and well known funds, including Polygon’s JD Kanani.

Advisors to the project include Coinbase’s first Head of People Nathalie McGrath who scaled the industry leading exchange from 10 employees to over 800, and Juan Suarez, who served as in-house counsel at Coinbase from 2013 to 2022.

# What Makes ZetaChain Unique?

ZetaChain is a blockchain that connects everything. It enables interoperability between any blockchains or layers by providing cross-chain value transfer and message delivery, as well as native omnichain smart contract support. Applications built on ZetaChain — omnichain dApps (odApps) — can leverage liquidity and data on multiple networks and read and update state on all connected networks.

ZetaChain’s native omnichain smart contract platform lets developers deploy contracts with the same ease as developing dApps for a single network like Ethereum, that orchestrate data and value across many or all chains. ZetaChain’s connectivity is chain-agnostic and can connect to and bring smart contract capabilities to even non-smart-contract chains like Bitcoin and Dogecoin. 

The ZETA coin powers ZetaChain, facilitating cross-chain value transfer, securing the blockchain through slashing/bonding/staking, paying for gas fees, processing transactions, and storing data. Through ZETA, users are able to safely transfer native value across chains without the common risks of bridging or wrapping assets.

# How Is the ZETA Network Secured?

ZetaChain is a Proof of Stake (PoS) blockchain built on Cosmos SDK and Tendermint consensus, which can connect to external blockchains (e.g., Ethereum, BSC, Solana, Avalanche, Terra, Bitcoin) and layers (e.g., Polygon, Optimism, Arbitrum) in a decentralized (without a single point of failure, trustless, permissionless), transparent, and efficient way.

The ZetaChain architecture consists of validators, observers, and signers. Validators participate in block production and receive rewards proportional to their bonded staking coins, observers reach consensus on external chain events and states, and signers, in a distributed fashion, hold standard ECDSA/EdDSA keys to sign messages on behalf of ZetaChain. ZetaChain utilizes GG20 leaderless Threshold Signature Scheme (TSS), which does distributed key generation and key signing. No single ZetaChain node or other individual has access to the complete private key at any point in time. All the inbound/outbound transactions and decisions made (through state change) are recorded in the ZetaChain blocks, which are available, immutable, verifiable, and completely transparent.

The only native value that can go cross-chain is the ZETA coin. The mechanism is a one way peg (i.e. burning X amount on chain A and then minting X amount on chain B). This value-transfer architecture reduces the attack surface substantially, resulting in an easier to understand audit and superior security compared to approaches that involve bridging and wrapping, which put users’ assets at risk when trading between chains. For example, total supply checks may be implemented directly at the contract mint site.

Theta (THETA) is a blockchain powered network purpose-built for video streaming. Launched in March 2019, the Theta mainnet operates as a decentralized network in which users share bandwidth and computing resources on a peer-to-peer (P2P) basis. The project is advised by Steve Chen, co-founder of YouTube and Justin Kan, co-founder of Twitch.

Theta features its own native cryptocurrency token, THETA, which performs various governance tasks within the network, and counts Google, Binance, Blockchain ventures, Gumi, Sony Europe and Samsung as Enterprise validators, along with a Guardian network of thousands of community-run guardian nodes.

Developers say that the project aims to shake up the video streaming industry in its current form — centralization, poor infrastructure and high costs mean that end users often end up with a poor experience. Content creators likewise earn less revenue due to the barriers between them and end users.

The Theta team has created a customer-centric business plan for their growing ecosystem of services focused on esports, music, TV, movies, and education. The list of Theta Network partners includes video platforms like Samsung VR, Cinedigm, Shout! Factory, Pandora.tv, Play Labs, and THETA.tv.

XDC Network (formerly known as XinFin Network) is a hybrid (public / private) blockchain platform that combines the transparency of public blockchains with the speed and security of private networks. With the help of blockchain technology and state-of-the-art infrastructure, the project intends to provide streamlined financial services to its users.

The protocol’s open-source software uses a delegated-Proof-of-Stake (XDPoS) consensus mechanism, which facilitates fast transactions, interoperability, and cybersecurity. The network can process 2000 transactions per second (TPS), and thanks to interoperable smart contracts and Ethereum Virtual Machine (EVM) compatibility, users can more easily scale their projects.

MultiversX is a blockchain protocol that seeks to offer extremely fast transaction speeds by using sharding. The project describes itself as a technology ecosystem for the new internet, which includes fintech, decentralized finance and the Internet of Things. Its smart contracts execution platform is reportedly capable of 15,000 transactions per second, six-second latency and a $0.001 transaction cost.

MultiversX rewards the community and active participants with EGLD tokens. EGLD, or Electronic Gold, is MultiversX's native token. It acts as a store of value currency to pay for network usage. The coin also serves as a medium of exchange between platform users and validators. Users pay transaction fees in EGLD and validators provide services.

EGLD allows developers to deploy smart contracts, protocols, and dApps on the platform. It empowers participants to perform any network action. Through staking and validation rewards, as well as transaction fees, EGLD manages the MultiversX network. Plus, EGLD is endowed with the functionality of a governance token, so its holders can vote on network decisions.

MultiversX was first announced in August 2019, and its mainnet went live in July 2020.
