Fast, flexible, and forward-driven, EOSIO is a next generation, open-source blockchain platform that enables developers, entrepreneurs, and businesses to build with confidence. We believe transparent and decentralized systems will keep users and builders in control and help architect integrity into our world.
EOSIO is a blockchain platform designed for the real world and recognized as the most performant blockchain platform. It is built for public or private, and permissioned or permissionless blockchain infrastructure. EOSIO is also adaptable to suit a wide range of business needs across industries with rich role-based security permissions and industry-leading throughput. Moreover, it’s designed for secure application processing.
Building on EOSIO follows familiar development patterns and programming languages used by existing non-blockchain applications. This means developers can create a seamless user experience with development tools they already know and love. Learn more about EOSIO in this video.
Developers and entrepreneurs are moving quickly to build a decentralized future. In this video, key members of the Block.one team, including our Head of Developer Relations Serg Metelin, describe the EOSIO ecosystem. EOSIO powers the two fastest public blockchains, EOS and Telos, and over 400 applications.
With blockchain platforms that use a proof-of-work consensus mechanism, there are fees associated with the processing of each transaction. EOSIO eliminates such fees 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, staking tokens covers any incidental costs by giving those who stake access to a proportional share of system resources. Learn how transactions are feeless on EOSIO in this video.
Block producers play a key role in the operation of the network. Block producers verify transactions on the EOSIO networks by collecting transaction data and storing that information in blocks. Once a block is prepared, block producers broadcast the block to the network for verification. After the block is verified, the transaction data is uploaded to the blockchain by the block producer who prepared it.
You can learn more about block producers who operate EOSIO-based blockchains in this video.
EOSIO is a network where the stake-holders have the authority to select node operators, as opposed to relying on proof-of-work-based mining collectives to confirm transactions. This distributes power amongst the token holders and aligns the interests of all parties involved. The number of node operators is determined by system architects, and may vary. The biggest difference between EOSIO and other blockchain protocols is how much we have decentralized the core concepts of EOSIO blockchains. Learn more in this video.

A hackathon is a sprint-like event, during which participants create solutions to real-life challenges. Using creativity and technology, participants engage mentors and create prototypes, fresh concepts, and other innovations.
A space for creativity and teamwork, an EOSIO Hackathon empowers engineers, designers, marketers, entrepreneurs, and any other innovators to build their ideas on EOSIO blockchain software.
Hackathons drive innovation through crowdsourced solutions. Designers, developers, entrepreneurs, and other creators collaborate to help various industries embrace new technology, test ideas before deployment, and more.
Participants have varied skills and backgrounds. Whether you’re starting your tech journey, learning more, or looking to test your skills–we invite all to join.
Technical requirements dictate that you must develop on EOSIO, use a smart contract, and more. For more information, please review the technical requirements and resources.
Yes, the hackathon is free to enter.
You don’t need an idea before the event. Most people don’t. Once the hackathon begins and you talk to other people, you might come up with an idea or collaborate with someone else on their idea.
Please go to the EOSIO Developer Portal for more information on how to access EOSIO.
There are several ways to get notifications if actions occur on the blockchain. If you’re testing locally, we recommend using EOSIO History Tools, specifically the state history plug-in with the fill-pg option. If you’re using the EOSIO Testnet, please read more about Dfuse support for EOSIO.
The team that develops the project owns the project and IP. We encourage you to share your code or make it open source, but it’s not required.
Google Cloud credits are incentives offered by our partner, Google, that provide access to GCP services so you can set up and operate an EOSIO node for the duration of the hackathon.
Once you have formed your team or confirmed to work solo, please have ONE representative from the team submit the following in the #gcp-credits Slack channel:
Each member will be given one coupon to redeem US$500 worth of Google Billing Credits and all coupons will be sent to the team representative within 3 days after this submission.
You can redeem your coupon in the Google Cloud Console. If you don’t have a GCP account, you will be prompted to create one.
Please refer to the Google Cloud Terms of Service for information on GCP credits.
People describe blockchain technology in different ways, but at its core, a blockchain is a public digital ledger that records transactions inside a given network. These transactions are publicly verifiable and cryptographically secure. In this video, Block.one’s founder and CEO Brendan Blumer describes how blockchain is simply a secure version of the internet that enables mass scalable secure data transfers.
Blockchain technology profoundly changes how businesses operate and are structured. In this video, the Block.one team explains why you should pay attention now, to what blockchain means for the future.
A smart contract combines a legal contract with code to automate the execution of specific terms of an agreement between parties in an objective way. Dan Larimer, former CTO of Block.one, and Bart Wyatt, from our Engineering team, explain more in this video.
Blockchain can be used for a lot more than just fintech. In fact, any multi-user system can benefit from using a blockchain. As members of the Block.one team explain in this video, the technology eliminates the need for passwords and paves the way for a more secure future. Across industries, projects and applications across industries use blockchain to innovate and drive more transparency in systems.
Blockchain technology is evolving at a rapid pace, but one thing is becoming increasingly clearer–it represents the future of trust and transparency. Block.one stands at the vanguard of the technology’s evolution, and in this video, key team members assess where it might go in the next five years.
Blockchain governance defines how a network reaches consensus, leveraging smart contracts to execute decisions in a verifiable, transparent, and auditable manner. Learn more in this video.
