Frequently asked questions

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.

Why build on EOSIO? How is it different from other blockchain technology?

EOSIO is an open-source platform that provides industry-leading transaction speeds and a sub-second block time latency rate, allowing developers to perform transactions at a lower cost through efficient resource management.

EOSIO is also designed to allow for a higher degree of configurability, particularly valuable for the creation and management of programmable infrastructures. This allows architects to deploy public or private blockchain networks, and implement a suitable default or custom governance protocol through executable smart contracts.

EOSIO is different from other blockchains because it provides upgradeable smart contracts, and is built on C++.

Why should people pay attention to blockchain technology?

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.

What is a blockchain?

A blockchain is a digital ledger comprising a complete record that is duplicated and distributed within a given network of computer systems, and enables mass scalable secure data transfers. These transactions are publicly verifiable and cryptographically secure.

What is an EOSIO “smart contract”?

A smart contract combines a legal contract with a form of computer code to automate the execution of specific terms of an agreement between parties in an objective way. Some distinguishing characteristics of EOSIO smart contracts include being written in C++ and the capability of sustaining upgrades after deployment without disrupting the blockchain network.
