区块链创始人之一Jimmy,区块链创始人随意改动对会员的承诺违法吗

Jimmy是区块链的创始人之一，他提出了一种新的技术，可以让会员以安全的方式进行交易。但是，有人质疑Jimmy随意改动对会员的承诺是否违反了法律。

首先，我们需要了解什么是区块链技术。区块链是一种分布式账本技术，它可以记录所有参与者之间的交易，而且不受任何第三方控制。这意味着，参与者之间的交易可以在区块链网络上安全地进行，而且不受任何第三方的影响。

所以，Jimmy提出的区块链技术可以让会员以安全的方式进行交易。但是，有人质疑Jimmy随意改动对会员的承诺是否违反了法律。

首先，我们需要了解会员的承诺是什么。会员的承诺是会员与组织之间的协议，它涉及到会员的权利和义务。如果会员的承诺被改变，那么会员的权利和义务也会随之改变。

其次，我们需要了解Jimmy随意改动对会员的承诺是否违反了法律。根据法律，会员的承诺是一项合同，它是双方的共同承诺，不允许任何一方单方面改变或取消。如果Jimmy随意改变对会员的承诺，那么他就违反了法律，也就是违反了双方的共同承诺。

因此，答案是肯定的，Jimmy随意改动对会员的承诺是违法的。如果他想要改变会员的承诺，那么他必须遵守法律，并且得到双方的同意。只有这样，才能确保会员的权利得到充分保护，也能确保双方的利益得到充分保护。

总之，Jimmy随意改动对会员的承诺是违法的，他必须遵守法律，并且得到双方的同意，才能确保会员的权利得到充分保护，也能确保双方的利益得到充分保护。

㈠ Blockchain Design Principles

What our team has learned so far—about blockchain-specific business and user needs—informs our Design work informs.

Currently, the IBM Blockchain Design Team is designing everything from supply chain processes to documentation, from open source developer tools to blockchain as a service. This is the nature of the industry: frantically exploring all possible applications for a technology that has the potential to dramatically reduce costs and inefficiencies in areas such as finance, healthcare, and government.

Although design has taken many different directions, there are some common themes in our users’ needs that have influenced our design principles as a team. This is the IBM Blockchain Design Team’s first iteration of these principles—what we focus on when critiquing our work and prioritizing design decisions.

“Just because blockchain technology is designed to eliminate reliance on trust, it doesn’t mean users will trust the machine or network.” — Jonny Howle, UX/UI Designer

Many of our users are in industries that handle highly sensitive information, and maintaining their trust is critical to our business. Almost everyone is new to blockchain, with varying levels of understanding and confidence. Users must view our products (and the people behind them) as reliable, trustworthy, and stable. We achieve this through careful data disclosure, consistency, feedback, prediction errors, and proactive coaching.

Some users will need more exposure to blockchain data than others – many users will need to understand how blockchain technology can replace their previous processes to feel that it is trustworthy. Exposure of data affects users' understanding of how the application works. For example, the data shows that a function call occurred, or it can prove that something is cryptographically secure.

When deciding whether to include a data element, we use the following hierarchy:

1. The data must be actionable.

2. If the data is not actionable, it must be used for trust-building and/or educational purposes.

"Old school" blockchain tools show you many long cryptographic hashes. They are not human readable. They are of no use to users...but people love them! Why? It's a comfortable feeling: "I can see a non-human-readable chaincode ID, so I trust that this thing I'm looking at is secure." — Ed Moffat, Design Lead

Creating visual consistency between the product and the customer experience is critical to perceived trustworthiness. We use a grid-based layout (with meaningful and proportional negative space), strong typographic hierarchy, and apply meaningful color.

Having a consistent user experience makes our users feel at ease, which is especially important with new blockchain technologies as it drives adoption and learning. — Tobias Hunter, UX Designer

Since the visual language of blockchain is still being codified, we need to be careful when using images to illustrate concepts. While we create associations with familiar elements to help users retain information, we are cautious about visual metaphors—simplifying certain concepts can actually mislead or cause confusion later.

We make every effort to use jargon-free, consistent terminology. Language should be concise, clear, and consistent with our users’ natural communication patterns. We maintain a conversational tone without being too casual or flippant. Our team pays special attention to words with meanings like identity , update , and network : while many blockchain concepts have similar meanings to commonly understood meanings, they can be very different and confusing.

We design for wherever our users are. Because blockchain is by definition distributed, we must design across borders by default: UI extensions, icon meanings, translations, etc. must always be taken into account. Additionally, many uses of blockchain are mobile in nature – we maintain a consistent experience regardless of the device used.

We help our users understand what's going on and reduce anxiety by designing for continuous feedback. Carefully used movement and animation help understand what's going on.

When you learn a foreign language, you learn by practicing and playing, not by reading a dictionary. We are making tools and documentation to allow our users to play around and try to learn this new technology. — Sam Winslet, Visual Designer

Users should always know what is happening, what just happened, and what will happen next. Time is an important element in blockchain applications, and many times a simple loader is not enough.

High-throughput distributed systems are asynchronous in nature, with multiple components of the system relying on timeouts or polling intervals. Transactions can be configured while waiting for the optimal block size to be reached (usually lasting a few seconds). The SDK will poll, wait, and retry creating a new channel. — Jason Yellick, Software Developer

We make sure we consider (and test after launch) the time an activity or feature will take and notify users. This also applies to any metrics in the interface - how many categories the user saw, how many were not shown, etc.

Our users love hands-on, interactive learning so they can learn while creating something tangible. — Raissa Xie, User Experience Researcher

Because blockchain is virtually immutable, we pay special attention to irreversible user actions. If an error occurs, we increase the friction or confirmation level to reduce the error and move directly to the next step.

Zero states are common in many of our products, so we make sure to provide a natural next step. Users must have clear, persistent navigation—it should be easy for them to know how to get back to their previous state and what the next step is.

Our users want to see simple instructions to get up and running as quickly as possible.

— Lucie Wu, UX Designer

Since control over visibility is a business requirement, we made sure to consider different views of the interface based on roles. We don't leave holes in the interface if the user doesn't have access to certain data.

Blockchain technology is relatively new and most users don’t necessarily know what they need. A good designer should know how to filter their opinions and come up with the best solution. Designers help them understand the benefits and possibilities this technology can bring to their lives by guiding them through the process.

— Andrea Lee, UI Designer

Our team anticipates the need for further assistance and attempts to reduce it while recognizing where our characters are most likely to go for help. We generate insights to create transparency and remove uncertainty, and provide suggestions for things users don’t remember.

Make an otherwise daunting learning task look easier by showing users their new vocabulary with tooltips and progress bars.

— Kayla White, UI Designer

We don’t include elements that clutter the interface or confuse users, regardless of context—every element has a Purpose, nothing is for decoration. We leverage common design patterns and reduce the amount of learning the user has to do.

In many cases, multiple of our roles will be part of the process. To facilitate collaboration, weDesign the steps before and after a given task for the user. Team adoption of our technology is critical to our business model, so it's natural that we value inclusive, accessible design.

Designing for complexity doesn’t mean making things simple. Make the task easier, but don't take away their control.

— Dante Guintu, UI Designer

Excitement over blockchain technology has increased the tendency to focus on machine needs rather than human needs. As designers, we must constantly refocus our efforts on solving problems and creating enjoyable experiences for humans. We must balance the tension between the nature of blockchain and human-centered design.

Even for non-technical users, the technical concept of blockchain seems incredibly alluring. -

Ed Moffat

Because the many applications of blockchain have very powerful potential, we must take care to act and design in an ethical manner. This means ensuring diversity is built into our designs—from user research participants to our teams themselves.

Our design team is in a constant state of collaboration: researching, testing, and being alert to changing user needs and design patterns. We are committed to protecting and advocating for our users, considering edge cases and outliers, and taking user emotions into account. We strive to improve our users' lives without creating new problems for them.

Design is not static. The main mantra of this group is that we strive for excellence, not perfection.

—— Sean Barclay, Creative Director

ㅡ Why the legendary blockchain founder Satoshi Nakamoto has always wanted to remain anonymous

The Bitcoin white paper was first published in late 2008, when the creator sent it to multiple people on the crypto mailing list recipient. Strangely, its creator pretended to be Satoshi Nakamoto, hiding behind a pseudonym.

Another reason for Nakamoto’s anonymity could be explained by the fact that creators of alternative currencies could easily put themselves at risk .

In 1998, Hawaii resident Bernard von Nohaus created a private currency called the Liberty Dollar. It had been popular for some time, but its minting was suddenly raided by the FBI and Secret Service in 2007. Following a 2009 criminal prosecution, the money was confiscated and Bernard von Neuhaus was convicted of "manufacturing private coins that competed with the official currency of the United States."

In addition, in 2007, a digital currency called e-gold was accused of being illegal because it did not collect enough customer information. Its owner was sentenced to house arrest and the company was shut down. Government agencies’ arrests of entrepreneurs over alternative currencies may have been a factor in China’s decision to remain anonymous.

Bitcoin is available to everyone. This means it can be used to pay for legal and illegal services, as well as legal tenders. However, it has been a popular payment method on darknet markets. Notorious dark web market maker and operator Ross Ulbricht was jailed for facilitating the trade of drugs and other contraband.

Ross Ulbricht appealed to the U.S. Supreme Court in December 2017 but remains in prison. It can be inferred that Nakamoto could face a similar fate if he reveals his true identity.

Who could he be?

In 2016, Australian programmer Craig Wright claimed to be Chinese. He presented some evidence, but later found that it was not conclusive since it was publicly available from books. He is also accused of falsifying announcements and blog posts to show his authentic Chinese version. For example, Ethereum founder Vitalik Buterin recently called Craig White a liar.

The other is Hal Finney. He is a famous cypherpunk and cryptographer. He was also the first person to receive Bitcoin from Japan in 2009. He was also the first person to download the Bitcoin client. However, before his death in 2014, Hal Feeney refuted claims that he was Chinese.

Some believe that Nick Szabo, a famous cryptographer, may have been Nakamoto. Before the launch of Bitcoin, he designed the architecture of a distributed digital currency, which he called Bitcoin. Although the architecture has never been moved, it is similar to Bitcoin's design. This has led to widespread speculation. But he repeatedly denied it.

While Nakamoto’s true identity may never be revealed, importantly, the operation of the technology will not be affected.
