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.

First Place: Team BLENDIT — B’lend it
Dapp for lending agricultural lands, helps farmers to find lands suitable for their crop. Landlords list their available land. Uses revenue site for checking the authentication of land and landlord. Landlord put up a price and preference for crop and duration. Once cancelled within a span of time refund it given. Farmers can check the previous cultivations and profit on the selected land. Time saving and easy land lending business.
Second Place: Team Esperer — BlinkALS
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.
Second Place: Team ReSeed — Project Decentralized Stock market for farmers
Synopsis: we are providing a platform for the common Man to invest in Farmers, each Farmer can set particular shares on his products so that the consumer can buy it before the seed is sown hence this transaction takes place in a blockchain ensuring legitimate transactions. The IoT devices on the farm will give holistic real-time progress of the crop growth which will be recorded on a permission distributed ledger, we have also developed an ML model to detect diseases in plants. Hence our app ensures that the farmers will get money on time and the consumer will be able to track where his food is grown and also get discounts when he buys shares from the farmer.
Third Place: Team AbleAlly — BloCERT
BloCERT is a webpage for issuing certificates for universities. Blocert uses Blockchian for adding and validation of certificates. Since Blockchain is used the certificates issued have time stamp . The time stamp and transactions made in the block are immutable. The issued certificates have unique hash values, using this hash value certificates can be accessed from any part of the world. Even if some one loses their certificate it can be obtained by entering the hash value.
Third Place: Team Blume — Hopon
Hopon allows you to share your mobile data to strangers securely and get paid for the data you share in crypto. This app is useful in areas where there is low connectivity on certain carriers. This also allows a user with extra data to earn from excess data by sharing it with those in need creating a marketplace. A user can set his own price per MB of data shared. We use Hedera hashgraph DLT in the backend to process end to end micro-payments. The demo link contains the APK, kindly install it in 2 android phones, turn “Provide internet” in one device which has excess mobile data and “Get Internet” in the device which has no internet connection. The app should discover device nearby and allow you to connect. Your phone may not show wifi symbol but it will be connected and you can try any internet services.
