x86

When some turn to ghosts in October, Qtum continued to push itself out there with our latest research findings to improve our technology for everyone.

Jordan Earls, Qtum’s co-founder and project lead on the x86 virtual machine, has been diligently improving on the x86 design. During the month of October, Earls introduced a token standard framework similar to an ERC20 token in Qtum’s x86; a post on Exposed Formats in Qtum x86; and a Memory Map of the x86 VM.

In addition, Earls published a proposal to allow free UTXO creation in Qtum. The proposal would allow for smart contracts to operate without the need of sending a small unit of Qtum to a certain address and grant it a UTXO.

“The blockchain is incapable of knowing that [your] addresses belong to the same wallet. So, what happens when you choose to send QRC20 tokens to some certain address, but then find out that address has no UTXOs. You will be incapable of spending the QRC20 tokens since you have no way of proving to the contract that you are that certain address.”

Qtum becomes an Amazon AWS Partner

After months of talks with AWS China, Qtum became the first public blockchain protocol to be easily deployed through an Amazon Machine Image (AMI) featured in the AWS marketplace. The partnership will make deploying a node for staking and dapp development almost seamless. We believe this will help developers engaging with Qtum software and will open the platform to mainstream developers.

We hope to grow this partnership with AWS as their clients become more familiar with the Qtum offerings. We see this as a way for enterprise customers to efficiently test use cases and implement them into their operations. AWS has already become the go-to provider for many web services, and we believe blockchain technology will present a complementary toolset to those services.

QtumX

The QtumX team revealed their groundbreaking research that will help accelerate the adoption of QtumX among enterprise customers.

First revealed on Qtum’s blog in mid-October, QtumX’s proposed SCAR (Scalable Consensus Algorithm) would help solve one of blockchain technology’s most pressing conundrums: choosing the appropriate block size. In most blockchain systems, the block size remains a static parameter, whereas SCAR dynamically adjusts the block size to be as large as needed.

Additionally, the QtumX introduced DDAO: Decentralized Data Access Object. DDAO works as a library which is used to access various decentralized systems with uniform interfaces, to perform CRUD (Create, Read, Update, Delete) operations. Based on this library, developers can easily manipulate various decentralized systems and build decentralized applications without knowledge about the underlying technology.

Qtum’s Patrick Dai at the University of International Business and Economics

Patrick Dai spoke at the University of International Business and Economics in Beijing as part of a workshop for developing countries. The participants were tasked to learn about the emerging technologies presented and explore how they could apply technologies like blockchain to some of the inefficiencies the world faces today, like those in the supply chain, financial inclusion, and IoT devices.
