0x (ZRX) Information{coin_name} ({symbol}) Information

0x is an open protocol that enables the peer-to-peer exchange of assets on the Ethereum blockchain.

The 0x protocol aims to support decentralized exchanges with an off-chain order book and on-chain settlements.

Questions and AnswersQuestions and Answers

What problem does 0x solve?
In the two years since the Ethereum blockchain’s genesis block, numerous decentralized applications (dApps) have created Ethereum smart contracts for peer-to-peer exchange. Rapid iteration and a lack of best practices have left the blockchain scattered with proprietary and application-specific implementations. As a result, end users are exposed to numerous smart contracts of varying quality and security, with unique configuration processes and learning curves, all of which implement the same functionality. This approach imposes unnecessary costs on the network by fragmenting end users according to the particular dApp each user happens to be using, eliminating valuable network effects around liquidity. 0x is the solution to this problem by acting as modular, unopinionated building blocks that may be assembled and reconfigured.
What are the differences between 0x protocol and state channels?
Participants in a state channel pass cryptographically signed messages back and forth, accumulating intermediate state changes without publishing them to the canonical chain until the channel is closed. State channels are ideal for “bar tab” applications where numerous intermediate state changes may be accumulated off-chain before being settled by a final on-chain transaction (i.e. day trading, poker, turn-based games). While state channels drastically reduce the number of on-chain transactions for specific use cases, numerous on-chain transactions and a security deposit are required to open and safely close a state channel making them less efficient than 0x for executing one-time trades. State channels are isolated from the Ethereum blockchain meaning that they cannot interact with smart contracts. 0x is designed to be integrated directly into smart contracts so trades can be executed programmatically in a single line of Solidity code.
Why must transaction fees be denominated in 0x token (ZRX) rather than ETH?
0x protocol’s decentralized update mechanism is analogous to proof-of-stake. To maximize the alignment of stakeholder and end user incentives, the staked asset must provide utility within the protocol.
How will decentralized governance work?
Decentralized governance is an ongoing focus of research; it will involve token voting with ZRX. Ultimately the solution will maximize security while also maximizing the protocol’s ability to absorb new innovations. Until the governance structure is formalized and encoded within 0x DAO, a multi-sig will be used as a placeholder.
What is the total supply of ZRX tokens?
1,000,000,000 ZRX. Fixed supply.
What types of digital assets are supported by 0x?
0x supports all Ethereum-based assets that adhere to the ERC20 token standard. There are many ERC20 tokens, worth a combined $2.2B, and more tokens are created each month. We believe that, by 2020, thousands of assets will be tokenized and moved onto the Ethereum blockchain including traditional securities such as equities, bonds and derivatives, fiat currencies and scarce digital goods such as video game items. In the future, cross-blockchain solutions such as Cosmos and Polkadot will allow cryptocurrencies to freely move between blockchains and, naturally, currencies such as Bitcoin will end up being represented as ERC20 tokens on the Ethereum blockchain.
What will the token launch proceeds be used for?
100% of the proceeds raised in the token launch will be used to fund the development of free and open source software, tools and infrastructure that support the protocol and surrounding ecosystem. Check out our development roadmap.
Explain how the 0x protocol token (zrx) works.
0x protocol token (ZRX) is utilized in two ways: 1) to solve the coordination problem and drive network effects around liquidity, creating a feedback loop where early adopters of the protocol benefit from wider adoption and 2) to be used for decentralized governance over 0x protocol's update mechanism. In more detail: ZRX tokens are used by Makers and Takers (market participants that generate and consume orders, respectively) to pay transaction fees to Relayers (entities that host and maintain public order books). ZRX tokens are used for decentralized governance over 0x protocol’s update mechanism which allows its underlying smart contracts to be replaced and improved over time. An update mechanism is needed because 0x is built upon Ethereum’s rapidly evolving technology stack, decentralized governance is needed because 0x protocol’s smart contracts will have access to user funds and numerous dApps will need to plug into 0x smart contracts. Decentralized governance ensures that this update process is secure and minimizes disruption to the network.
Will there be a lockup period for ZRX tokens sold in the token launch?
No, ZRX tokens sold in the token launch will immediately be liquid.
Will there be a lockup period for tokens allocated to the founding team?
Yes. ZRX tokens allocated to founders, advisors and staff members will be released over a 4 year vesting schedule with a 25% cliff upon completion of the initial token launch and 25% released each subsequent year in monthly installments. Staff members hired after the token launch will have a 4 year vesting schedule with a one year cliff.
