Technological Revolution for Veil’s Modification of Features

Technological Revolution for Veil’s Modification of Features

We know that every platform must always adjust quality by integrating or collaborating several technological components that are in line with the times. But in fact, it is not just the developmental factors that affect a platform in modifying its technological components. For example, like what happened in the process of modifying the Veil wallet from the Veil Core Wallet 1.0.2.0 version to the Veil Core Wallet 1.0.3.0 version. Which of these updates is done to protect the Veil network in the face of all the risks that come from system damage to the Zerocoin technology component. This can be called the Zerocoin “domino effect” of internal and external technology components.

Recorded from the end of January to April, Veil has modified his wallet 4 times. Here are some details about the performance, technological components, and causes of modification, the following:

  1. January (Veil Core Wallet 1.0.1.4)
    – Performance improvements in accelerating the process of introducing orphans and forks components
    – Users are allowed to specify certain coin denominations in the shopping process. Which in this process purchases RPC using denomination filters.
    – Bets will not stop until the miner is close enough to the end of the chain.
    – Reduce the amount of potential from joining the stake miners which results in excessive bets.
  2. February (Veil Core Wallet 1.0.1.5)
    – Reducing the amount of betting process for orphans
    – Multithreaded Zerocoin Spend Validation feature
    In this version to validate the proof of zero knowledge, many threads are needed. Evidence of zero knowledge means that written evidence states that Zerocoin has been spent, without using additional information such as the amount of Zerocoin spent and the final method.
    – Increase speed in the synchronization process on the blockchain system
    – Determine the location of the fixed node, so that it stays in the correct chain and the latest block
    – Improvements to bugs
    – Stabilizing the price of Zerocoin which had been uncontrolled in several scenarios
    – Improved performance of new RPCs that can provide information about user and serial Zerocoin denomination status, publisher or pubcoin hash, and serial hashes.
    – The rescanringctwallet feature is responsible for finding lost CT or CT Ring balances.
    – Zerocoin denominations that can be controlled by the user, which will then be automated by setting the automintdenom.
  3. March (Veil Core Wallet 1.0.2.0)

The process of modifying this version is a mandatory thing to do to prevent block 86350. Because previously there was an error in calculating the budget, which process of inspection occurred not on the superblock. Then the inspection will start from 50 blocks before the superblock. Notification to users, to remain in the correct chain, before blocking 86350. Some things that will affect Zerocoin’s performance are the process of printing Zerocoin and Basecoin back into CT balances, Zerocoin denominations that will be used first, if the denominator lasts a long time, choice Zerocoin Minting feature that can automatically print as much as possible from the available balance, and before spending the mint collection Zerocoin will be refilled.

4. April (Veil Core Wallet 1.0.3.0)

This update was due to a system malfunction announced by Zerocoin. This update is different from other types of updates that aim to improve quality, but Veil Core Wallet 1.0.3.0 for saving or protecting network performance. You could say Veil Core Wallet 1.0.3.0 indirectly helped replace the role of Zerocoin, but still could not maintain the anonymity of personal data and the number of user transactions. This certainly undermines the principle of Veil as a privatized service provider platform in terms of investment and payment transactions. Protection measures on the network are only useful for maintaining speed in processing transaction transaction data. This anonymity service cannot be returned even though the CT and CT Ring technology components are not affected. At this time data — user data from the beginning of the transaction to date, will not be displayed anonymously again.

The development of technology is not only positively welcomed, by integrating it into the platform. But the development of technology can also be welcomed negatively by parties who are not responsible for using it. So from that we need care and thoroughness for all platforms in dealing with this.

The Bitcoin Block Clock Jr. Is Half Full Node, Half Work of Art

The Bitcoin Block Clock Jr. Is Half Full Node and Half Work of Art

bitcoin is a decentralized system of digital cash in which users don’t need to trust anyone else with their money; however, the full benefits of this technology are only seen when users operate a full node on the network. The vast majority of bitcoin users do not operate their own full nodes, but one man is trying to change that with a piece of hardware he calls the bitcoin Block Clock Jr.

There are many good reasons for individual Bitcoiners to operate a full node. Full nodes are responsible for validating transactions and blocks on the bitcoin network. Only by running full nodes can users know with full certainty that they received a valid payment. Additionally, the more users that run full nodes, the more decentralized the bitcoin network is, making it harder to shut down or corrupt.

And as Sia Co-Founder David Vorick pointed out in a talk at this year’s MIT bitcoin Expo, those who do not operate their own full nodes do not get a say in the matter when hard forks are deployed on the network. “If you’re not running a full node … your opinion on whether or not you like a hard fork is less relevant because, ultimately, if you’re not validating the rules and someone gives you a transaction following a different rule set, you don’t have a way to detect that,” he explained.

Running a full node, however, has been a rather expensive proposition. As a result, larger, economically invested entities that are better able to support full nodes have had more of a say.

According to Vorick, users can be dragged along with miners and large businesses if the cost of running a full node is too high: “If full nodes are expensive to run, only people who are capable of running nodes really have any say in what happens in a contentious upgrade.”

Matthew Zipkin is the man behind the bitcoin Block Clock. A sound engineer by trade, he has been working in his spare time on creating full nodes that are both affordable and fun to use. During a recent discussion with bitcoin Magazine, Zipkin revealed his desire to create a piece of hardware for operating a low-cost bitcoin full node that isn’t boring.

A bitcoin Full Node That Isn’t Boring

When commenting on his reasoning for creating the bitcoin Block Clock, Zipkin pointed to the full node devices made by Bitnodes before they were acquired by 21.

“I always wanted one, but they disappeared when they got bought out, so I decided to build my own,” said Zipkin.

While there are other full node options out there, such as Bitseed, Zipkin wanted to make something that was more than a piece of computer hardware that would sit on the floor next to a router. Zipkin wanted to turn a bitcoin full node into a work of art, and that’s exactly what he did.

Zipkin built the first version of the Bitcoin Block Clock last year, and it was on display at the SF Bitcoin Meetup’s “Proof of Art” event in May of 2016. After receiving positive feedback at the event and on Reddit, Zipkin decided to make a smaller version of the full node hardware to sell.

The bitcoin Block Clock included a screen that displayed various live information about the bitcoin network. Zipkin put the original version of the bitcoin Block Clock for sale on OpenBazaar and Purse.io, but it hasn’t sold.

“I priced it pretty high because it’s art and I love it and kind of want to keep it,” explained Zipkin. “So of course it still has not sold.”

Creating the bitcoin Block Clock Jr. With Bcoin

In an effort to create a version of the bitcoin Block Clock that could be produced at a lower price, Zipkin turned to Raspberry Pi Zero and Bcoin, which is an implementation of the bitcoin protocol written in Node.js.

“I discovered Bcoin was super easy to install and use, and the codebase was easier for me to review because it’s in Javascript instead of C++, and was built from scratch by a small group of developers (basically just two guys), so everything is really well labeled and consistent,” explained Zipkin.

Of course, the problem with using SPV mode is that it’s not a full node and the device won’t receive all of the information related to a new bitcoin block as it’s mined on the network. Zipkin opted for the pruned full node option in Bcoin in an effort to lower the system resources required to operate the node on Raspberry Pi Zero.

“With pruning, I get all the fun block details I wanted to display,” said Zipkin. “I even submitted a pull request (which got merged!) to Bcoin to make my application work even easier.”

Zipkin described the LED displays on the bitcoin Block Clock Jr. as follows:

“The bitcoin Block Clock Jr. has two LED rings. The outer ring of 24 LEDs indicates recent blocks. Each LED represents 2 minutes, and they “tick” clockwise around the ring. The color of the LED is determined by the block’s version (BIP 9 version bits combined with keywords from the Coinbase scriptSig like “/EXTBLK” or “/EB1/AD6/”). The inner 16-LED ring indicates the progress of the current difficulty period (2,016 blocks, or about two weeks). It starts blue and gradually turns more and more red as the meter fills up. The tiny little display screen indicates some details about the latest block: height, size, version (and extra scriptSig version) and the adjustment period progress. I added a little web interface so I could turn the lights off at night without having to SSH into the Pi every time.”

An Economical Way to Contribute to the Network

While Zipkin noted that the original bitcoin Block Clock displays much more information and also comes with full wallet functionality, he also pointed out that the latest model proves that bitcoin users only need about $20 to run their own full nodes (at least in pruned mode).

Having said that, Zipkin admitted that the bitcoin Block Clock Jr. can struggle to keep up with the network at times.

“Bcoin plus my Python script and all the GPIO display output just barely hangs in there on this tiny underpowered computer,” said Zipkin. “The Python script has a method to restart Bcoin when it crashes and monitor it as it catches up to the network.”

All of the technical details of the bitcoin Block Clock Jr. are open source and can be found on GitHub.

Zipkin has now placed the bitcoin Block Clock Jr. for sale on OpenBazaar and Purse.io.
