Frequently Asked Questions

Block.one

Who is Block.one?

Block.one – a producer of highly scalable, high-performance, open-source software – is at the forefront of developing the next generation of the internet. We make it our mission to build a more secure and connected world.

EOSIO

Why Build on EOSIO?

EOSIO is a blockchain platform designed for the real world. Built for both public and private use cases, EOSIO is customizable to suit a wide range of business needs across industries with rich role-based security permissions, industry-leading speeds and secure application processing. Building on EOSIO follows familiar development patterns and programming languages used by existing non-blockchain applications so developers can create a seamless user experience using development tools they already know and love.

What Projects are Building on EOSIO?

On EOSIO, businesses across a multitude of sectors and industries are moving quickly to build a decentralized future for commerce and communications. In this video, key members of the Block.one team, including our Head of Developer Relations, Serg Metelin, describe the EOSIO ecosystem.

How are Transactions Feeless on EOSIO?

With blockchain platforms that use a proof-of-work consensus mechanism, there are fees for each transaction processed. EOSIO eliminates these by having the network shoulder the burden of these costs – through inflation – rather than making the individual users of the network pay to access its combined resources. In other words, ownership of tokens covers any incidental costs involved.

Is EOSIO Centralized?

In EOSIO, token holders can elect 21 block producers to process transactions, which distributes power amongst the token holders and aligns the interests of all parties involved. The biggest difference between EOSIO and other blockchain protocols is how much we have decentralized the core concepts of the chain.

Is Block.one Launching the EOSIO Blockchain?

“EOSIO blockchains can only be launched by communities,” said our CEO Brendan Blumer. Rather than having one entity control the blockchain, multiple parties come together to validate transactions, making it a truly decentralized system.

What are Block Producers?

“Block Producers are like the DJs at a radio station,” said CTO Daniel Larimer. Find out what that means from this video about Block Producers who operate EOSIO based blockchains.

EOSIO Challenge

What is the EOSIO Challenge?

The EOSIO Challenge is a program that promotes blockchain through various collaborative challenges. For example, we may ask you to explore different ways to enhance cross-chain capabilities. To learn more, visit our page on the Devpost site.

When does the EOSIO Challenge start?

The EOSIO Challenge is live, and the first challenge is open for submissions (Running a Solidity Smart Contract in an EOSIO Contract). For further guidance on individual challenges and the submission and review process, please visit Devpost’s site.

When is the deadline for submissions?

The first challenge of the EOSIO Challenge is open for submissions (Running a Solidity Smart Contract in an EOSIO Contract). For further guidance on individual challenges and the submission and review process, please visit Devpost’s site.

Who from Block.one sits on the judging panel?

The judging panel consists of members of the Block.one Engineering Department.

Will each challenge in the EOSIO Challenge have a $200,000 reward?

Challenge prizes will be paid in US dollars, and each challenge will have its own prize amount.

Will the prizes be paid in tokens?

No, the prize will be paid in US dollars. Block.one does not sell or distribute EOS tokens, the token native to the EOS Public Blockchain. The EOS community runs and manages the token.

Will Block.one use ideas from winning submissions in future products?

For details about how submissions will be used for both open-source projects or Block.one products, please read individual challenge details on the Devpost website.

Who is eligible to participate?

This challenge is open to all. You don’t need prior experience building on EOSIO or Ethereum protocols. Block.one employees cannot participate.

Will you accept team submissions?

Team submission requirements vary by challenge. For more information, please visit the individual challenge page on the Devpost website.

EOSIO Bug Bounty

What is the EOSIO Bug Bounty Program?

The EOSIO Bug Bounty Program welcomes hackers and developers to submit security issues in Block.one’s product suite or services. Through the findings of skilled security researchers globally, Block.one hopes to both strengthen the EOSIO protocol and this crucial way we identify technological weaknesses.

When does the bounty program begin?

The EOSIO Bug Bounty is ongoing and accepts submissions as vulnerabilities are identified. If you find a security issue, send your submission through the HackerOne Block.one Program site.

When is the deadline for submissions?

We encourage you to submit potential security issues as you discover them.  If you find a security issue, send your submission through the HackerOne Block.one Program site

Who reviews the submissions and makes decisions on bounty rewards?

Block.one’s Cybersecurity and Engineering teams review the vulnerabilities.

What is the bounty reward?

Bounty rewards depend on the severity of the vulnerability, with the final reward amount determined at the discretion of the review panel.

Is the bounty paid in EOS tokens?

Block.one does not issue bounty rewards in EOS tokens; all rewards are paid in US dollars.

If I submit an entry for a bug that has already been identified, can I still qualify for a bounty?

To qualify for the bounty, your submission must be original.

If I identify a security vulnerability on any of the public implementations of the EOSIO protocol, can I still receive a bounty reward?

Block.one does not monitor or maintain public implementations of the EOSIO protocol and therefore, any security vulnerability on a public chain should be submitted to that respective chain’s vulnerability team. To qualify for Block.one’s EOSIO Bug Bounty, all reports and security issues must be found on the core EOSIO protocol.

If my submission is deemed a credible vulnerability, will Block.one publish the information about me and my reward?

While our team may work closely with you to obtain additional information regarding the vulnerability you’ve identified, we do not publicly announce awarded bounties.

Who is eligible to participate?

We encourage developers and others in the EOSIO community to participate in the EOSIO Bug Bounty Program. For more information, please visit the HackerOne site.

Will you accept team submissions?

If you’re on a team, an individual team member must submit the vulnerability.  For more information, please visit the HackerOne site
