IoT Chain is pleased to announce a strategic partnership with Silicon Valley based SWFT Blockchain, a one-click cross-chain currency transfer exchange and wallet. The two parties will jointly carry out in-depth co-operation and promote the development of a new generation of blockchain technology. ITC has now launched on SWFT platform, which can realize cross-chain exchange with 35 Tokens.

# COMMUNITY ACTIVITIES
## ITC and SWFT launched two airdrop initiatives [Chinese Community]:
Poster Sharing — Sharing of an ITC & SWFT poster on WeChat moments and obtaining 10 likes from friends
Trading Competition — Trade ITC on the SWFT app

## ITC ENCYCLOPEDIA

## Consensus algorithm
Consensus is the basis for building blockchain trust, which is usually used to deal with issues such as transaction verification/confirmation in a very short time, and is generally implemented through specific mathematical algorithms. For example, IoT Chain uses VRF+PBFT, Bitcoin uses POW (Proof of Work) and Ethereum uses POS (Proof of Stake).

## Chain ID
A chain ID is used to realize EIP-55 in order to support checksum address encoding.
