Here are the key gainers and losers among ASX small caps at 12.45pm AEDT Thursday:

In the green

Any blockchain is good blockchain in some corners of the market — something augmented reality app developer Thred (ASX:THD) has successfully cashed in on.

The software maker was leading the winners at midday, up 27 per cent at 1.1c after announcing details of a blockchain integration, in conjunction with its university “O-week” activation.

It is the next phase in the apps development, after launching at Schoolies week last November — though early reports show teens are reluctant to pay for the service. The company has yet to report any revenue.

Blockchain technology, which provides an encrypted, public ledger of transactions, is best known as the basis of cryptocurrencies such as bitcoin. But it has many other potential applications such as enforcing digital contracts, securing public records or regulating online voting.

Junior explorer Genesis Resources (ASX:GES) was up 17 per cent to 1c on no news.

An initial resource upgrade at its Ulysses project is due to be completed by the end of the month, and could put it on the radar for more established gold producers.

Results from Service Stream (ASX:SSM) buoyed its share price by 11 per cent to $1.38.

The company reported revenues of $294.1 million, with a half-year profit — the ninth consecutive half-year increase in each of EBITDA and profit.

Toy maker Funtastic (ASX:FUN) slipped 12 per cent to 17c despite no public news anouncements.

IT service provider CommsChoice Group (ASX:CCG) was down 12 per cent to 21c.

The company is only new to the bourse after commencing trade on December 21 at 25c.
