Question 1

How to install EOSIO on Ubuntu 20.04?

Accepted Answer

Download the .deb package from GitHub releases and use sudo apt install, as detailed in the README. Ensure you follow the uninstall script if switching from source builds to avoid conflicts.

Question 2

EOSIO vs Ethereum: which is better for dApps?

Accepted Answer

EOSIO excels in high throughput and low latency, ideal for performance-critical dApps like gaming or finance, while Ethereum offers a larger ecosystem and more established standards like ERC-20. Choose based on speed versus community support.

Question 3

Are there transaction fees on EOSIO?

Accepted Answer

EOSIO uses a free rate-limited model where transactions are subject to limits based on staked resources, not direct fees. This reduces user costs but requires careful resource management and staking.

Question 4

How secure are EOSIO smart contracts?

Accepted Answer

Smart contracts run on WebAssembly for sandboxed execution, enhancing security. However, the platform includes disclaimers about potential bugs and relies on third-party libraries, so thorough auditing and testing are crucial.

Question 5

Can I build a private blockchain with EOSIO?

Accepted Answer

Yes, EOSIO supports private deployments with hierarchical permissions for controlled access. Refer to the documentation for setting up custom networks and configuring role-based security.

Question 6

What is the learning curve for EOSIO development?

Accepted Answer

Developing on EOSIO requires understanding blockchain basics, C++ for smart contracts (compiled to WebAssembly), and platform-specific tools like cleos and keosd, as outlined in the getting started guide. Expect a moderate to steep curve for newcomers.
