Technical features of IOST

Different from previous blockchain platforms, IOST has more decentralized consensus, which costs less and have better performance.

1) Unique Consensus Mechanism

IOST’s consensus algorithm — PoB — includes a more decentralized committee election process than current DPoS systems while still maintaining the scalability benefits and censorship resistance.

2) Easy-to-develop smart contract

Coded in Javascript based on V8 virtual machine.

3) High Scalability

Ideally the mainnet’s performance can be 8000 TPS. NFT (Non-fungible token), initial offerings etc can all be developed in IOST ecosystem.

4) Low Resource Fees

There exists two kinds of resources on IOST: iGAS and iRAM. iGAS can be generated through staking tokens. iRAM can be purchased from the system with low price.

Second Place: Team EspererBlinkALS

BlinkALS is the World’s first portable intelligent personal assistant for ALS patients that helps them communicate easily and effectively with their caretaker, reach out for help in case of emergency situations and save his thoughts to the personal notebook on Cloud. BlinkALS offers low-cost context-specific assistance for people suffering from ALS in low and middle-income countries. BlinkALS system comprises of a portable BlinkALS device plugged on to a spectacle frame and a BlinkALS mobile phone application (mobile is placed on a stand in front of the patient). BlinkALS mobile phone application allows the patient to communicate by displaying a sequential array of characters on the mobile-phone screen one-by-one along with the options to send the message, save the message to the personal notebook on Cloud or to ask for assistance. The BlinkALS device senses user input through the eye-blink gesture detection and sends it to the BlinkALS mobile phone application in real-time which in turn builds a string of characters. The mobile app then applies text-analysis algorithm on the character string to split it into words before speaking it out and sending it to the caretaker’s phone or before saving it to the patient’s personal notebook on Cloud.
