Qtum Neutron & x86 Virtual Machine

Qtum Neutron is the infrastructure to support new virtual machines and the first will be the x86 virtual machine allowing smart contract development in C, Rust and other languages. The EVM will continue, but the x86 VM will allow easy creation of smart contracts using safe, well-known, mature languages and tools, and also provide a new state memory model using NeutronDB.

You might have heard — Qtum is developing Neutron — a middleware technology to allow multiple virtual machines to run on Qtum and other blockchains.

Sounds cool, if you can grasp all those technical terms. So here it is, simply explained.

The bitcoin halving is upon us, and at block 630,000 (approximately May 12, 2020) the bitcoin “subsidy” or “reward” for verifying transactions with newly created coins will drop from 12.5 BTC to 6.25 BTC per block. In this blog, we review the bitcoin halving, how it works, and how halving works for Qtum.

First though, why is there a halving? Miner incentives and token economics are beyond the scope of this article, but we can surmise that Satoshi wanted to give higher block rewards to attract early miners (now everyone would mine bitcoin if they could) and did not want to create an inflationary asset with a supply that grows forever.

Recently, the Chinese government State Council added a regulation to reform the market for providing data as part of the production process. Data must be used as a production input to strengthen the entire market, changing from old analog ways to move to the new digital economy. There must be a right to confirm data, with data only sold if it can be verified.

Over the past decade, big data has gradually permeated people’s daily lives, but it still faces many problems, the most important of which is data privacy. On April 14, 2020, Yi Zheng, lead developer (China) and co-creator of the Qtum Phantom privacy protocol, was interviewed by Guosheng Blockchain. The discussion focused on privacy protection and the development of privacy technology, including privacy technology implementation for big data and use cases to solve industry pain points.

Qtum is developing Neutron — a key innovation to allow multiple virtual machines to run on Qtum and other blockchains. Neutron represents a holistic solution for integrating virtual machines and is a major rearchitecting from the initial more “hardwired” approach for the x86 virtual machine. Neutron is under active development for deployment this year and is now ready for its close up.

In March 2020 the Qtum Foundation completed the final scheduled vesting of funds, representing 5.75 million QTUM for future business development, academic research, education, and market extension. Specifically, 3.5 million Qtum will go towards business development initiatives, and 2.25 million Qtum will be used for academic research, education, and market extension.

With this final vesting, the circulating supply is now approximately 102,335,000, consisting of the original 100,000,000 coins created in the genesis blocks plus the block rewards to date. Circulating supply will reach a maximum capped supply of 107.82 million with additional block rewards over the next 25 years, where the current inflation rate is 0.9% and will drop with the halving process.

Qtum Core

Qtum core updates normally consist of Qtum Improvement Proposals. These QIPs are generated by both our developers and the community and in some cases requests from enterprise users. Our developers evaluate the impact of each QIP and work on high priority QIPs. All bug fixes and feature enhancements that have been issued to the core project will be listed here.

•    Offline Staking is under code review and testing.
•    Preparing QIP describing offline staking.

Qtum Neutron & x86 Virtual Machine

Qtum Neutron is the infrastructure to support new virtual machines and the first will be the x86 virtual machine allowing smart contract development in C, Rust and other languages. The EVM will continue, but the x86 VM will allow easy creation of smart contracts using safe, well-known, mature languages and tools, and also provide a new state memory model using DeltaDB.
