Outside Krungsri Bank

Korea

The Qtum Team visited Korea last week to present our latest updates. Our growing community there has over 2000 members in Kakaotalk, a Korean social media network. Patrick spoke for an hour about the Qtum project, followed up by Xiaolong, who explained some technical updates.

We met with Medibloc, a project building on the Qtum platform, and the Coinone exchange. After meeting with the Korean press, we were featured in some local media!

Thailand

This past week, part of the Qtum team ventured to Thailand to share our knowledge of blockchain technology with local citizens, businesses, and government officials.

In Thailand, Energo Labs CEO, Ray Chu, and Energo angel backer Bo Song, along with Qtum met with several institutions to enlighten people about the opportunities at hand. We had lunch with Korn Dabbaransi, a former deputy prime minister of Thailand, and his son Ko Dabbaransi. We were also introduced to several representatives from Krungsri Bank.

Development Updates

Bugs fixed:

[RPC] Fixed a bug where `getaccountinfo` would return a backward hex address

[Consensus/MPoS] Fixed a consensus bug with MPoS where rewards were calculated to include contract refunds, causing a pre-release version of testnet-2 to become stuck

[Consensus/AAL] Fixed a consensus bug where a malicious staker could bypass the AAL and spend funds that belong to contracts. This was the reason for the v1.1 release of testnet-2. The cause was that OP_SPEND was not actually mandatory, and furthermore by not including OP_SPEND in vin[0].scriptSig, a bypass in AAL consensus rules was possible.

[Staker] Fixed a bug where the staker could behave improperly sometimes when reverting contract state, resulting in the chain becoming stuck
