Topic: [ANN] (QTUM) - A Scalable Smart Contract Platform w/ Proof of Stake - page 11. (Read 525472 times)

From the previous blogs in this series, you should be aware that the Super Staker provides Proof of Stake services for delegated addresses and stakes its UTXOs when it wins a block reward for the delegated addresses in Qtum’s Offline Staking protocol.

This means the Super Staker must have its own inventory of UTXOs ready to be staked, and locked in a stake for 500 confirmations (blocks). For a Super Staker managing a large number of delegated UTXOs, how many UTXOs should it hold for staking? If the Super Staker has all its UTXOs committed to stakes it will stop staking and can’t win any block rewards.

TL;DR For Qtum Offline Staking, the Super Staker must have enough UTXOs to stake proportional to the Delegated Weight it is staking. A simulation shows the appropriate Wallet Weight for various Super Stakers, for example, with a Delegate Weight of 5% of Network Weight, the Super Staker should have a Wallet Weight of 15,000 QTUM.

Very cool program, just setup a node on a vps and realized I am late to the party for the Global Full Nodes Incentive Program. My fault for not looking more closely at the dates

I might as well leave the node up for a month since I set it up

Wishing everyone much luck with this project

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.

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.

Qtum SDK

QtumJ is BitcoinJ ported to the Qtum blockchain protocol. The BitcoinJ library is a Java implementation of the Bitcoin protocol, which allows it to maintain a wallet and send/receive transactions without needing a local copy of Bitcoin Core. It comes with full documentation and some example apps showing how to use it.
