a16z latest long article: The most underrated type of token, not for speculation

Source: A16z Crypto by Tim Roughgarden, Eddy Lazzarin, Miles Jennings, Scott Duke Kominers Compiled and organized by: bitPushNews In our article on token classification, we introduced seven types of tokens, including web tokens, collectible tokens, and meme coins. Among them, the least explored and underappreciated is Arcade Token: a token with a relatively stable value within a specific software or product ecosystem, usually managed by an issuer (such as a company). Basically, Arcade Tokens are the blockchain equivalent of assets people are already familiar with in the real world: air miles, credit card points, in-game coins, etc. What all of these assets have in common is that they are all internally circulated currency to support the operation of a market economy: for example, frequent flyer miles and reward points can encourage brand loyalty and are used to buy tickets and upgrades; in-game coins can be used to buy and sell items in video games. Although companies have been using these assets for decades, almost all previous instances have run on centralized databases, limiting ownership, portability, and user choice. Arcade Tokens based on public chains are different; they are open, interoperable, and composable, which provides a new set of market design advantages. This article aims to answer the most common questions we receive about arcade tokens: what they are, what they do, why are they valuable, how builders use them, the design trade-offs they involve, and the opportunities they present. What are Arcade Tokens (Arcade Tokens)? At the technical level, an arcade token is a digital currency designed for consumption within its associated application ecosystem — its supply and demand are managed flexibly to maintain price stability. Please first think of them as currencies in the digital economy. So where did the term “arcade token” come from? Whether you've been to an arcade arcade or not, you're probably familiar with the concept: you walk into an arcade; exchange cash for coins, usually physical; then use those tokens to play a few rounds of “Bumblebee,” “Crocodile Panic,” or other games you like. These tokens allow you to participate in the arcade's economic activities. The arcade hall analogy clearly illustrates how these tokens work: arcade tokens have a relatively stable value within the economic system to which they belong — whether within a single service or between multiple services. The relative stability of the value of arcade tokens distinguishes them from other types of tokens, such as tokens that derive value from the operation of an underlying asset (such as asset-backed or collectible tokens), the operation of a decentralized network market (such as a network token), or speculative investments in a specific entity (such as company-backed or securities tokens). As funny as the name sounds, arcade tokens are a powerful, programmable economic primitive — they're the key to unlocking a new field of crypto design. What is not an arcade token? Once again, the most substantial difference between arcade tokens and other types of tokens is that arcade tokens are not meant for investment or speculation. Unlike network tokens or securities tokens that people usually earn in anticipation of a return on investment, arcade tokens are used for spending. People sometimes refer to arcade tokens as “functional tokens” because they are designed to provide, um, functionality. We avoid using this label because it suggests that other types of tokens lack functionality, which is by no means true. (See our “Defining Tokens” article for more information.) Alternative names for arcade tokens can include “points” (although in common parlance, this usually means that relevant records are kept on a private ledger rather than on a public chain) and “loyalty tokens” (which only describe a specific application). This doesn't mean that the value of an arcade token will never change—as described below, the price of an arcade token may fluctuate slightly over time. However, arcade tokens usually provide an unlimited supply at current prices, and do not provide, promise, or imply financial returns. This means they are generally unsuitable as investment products and are therefore generally not subject to US securities laws. What are the benefits of arcade tokens? Why should builders consider using them? Arcade tokens enable builders to create and distribute value in the digital economy. Crucially, this ability to create and distribute value can motivate user behavior, drive early growth, and create network effects — without relying on external capital or speculative demand. This intuition is simple, and once again matches the arcade analogy: if you run an arcade, you probably want to control the supply of tokens...

Opinion: The world's largest stablecoin looks shaky

Opinion: The world's largest stablecoin looks shaky

Original title: The world's largest stablecoin looks shaky Original author: Liz Hoffman Original Article Source: semafor Compilation: MK, MarsBit investors are increasingly worried that Tether, the digital token that plays an important role in linking the cryptocurrency economy to the US dollar, may become the next cryptocurrency kryptonite. Last spring, some hedge funds bet on Tether, betting that Tether (named after being pegged to the US dollar) would fall below the $1 peg. Their views are so contrary, that Wall Street charges them relatively little — around 4% of the annual fee, about the same as what you're now betting on Warby Parker stock. Today, one of these traders said you can't short Tether at almost any price. There are so many fears that it will be the next casualty of the rapidly expanding cryptocurrency storm that no one wants to take the other side of this bet, even for a hefty fee. Tether initially did not respond to requests for comment, and it said in a statement that its “reserves are still extremely liquid.” It also said that the collapse of the cryptocurrency exchange FTX has caused a shortage of liquidity, making it difficult for short sellers to borrow Tether. LIZ's point of view As we've seen over the past few weeks, infectious diseases are spreading fast, and Tether is clearly a place where it can migrate and ferment. Investors are most concerned about the actual support of Tether worth $65.6 billion, the largest in a series of “stablecoins,” which claim to be backed by easily sellable assets such as currency and government notes. Since Bloomberg reported last year that it held venture capital such as short-term loans to Chinese companies, Tether said it had moved capital into safer areas such as government bonds. A September report prepared by Tether's auditors to reassure customers showed that more than 80% of its $68 billion was quite safe and liquid — $40 billion was US Treasury bonds, $7 billion was money market funds, and $6 billion was cash. (After a wave of redemptions, the list of these assets is smaller today). The rest, though, are investments that are more difficult to value and sell, and Tether knows very little about these investments. Its spokesperson confirmed to the Wall Street Journal last week that it has approximately $6 billion in loans secured by its own coins. A loss of confidence in Tether, like a blow to the FTX token, would reduce these collateral to zero and take away 10% of Tether's assets. It also has $2.6 billion in “other investments,” according to the September report. According to a global research firm commissioned by hedge funds that bet on Tether's price, it's not entirely clear what's inside, but they are likely risky shares in other cryptocurrency companies held by their owners and affiliates. Semafor reviewed the findings of its report and found that Tether held shares in more than a dozen cryptocurrency startups. Semafor can verify some, but not others. We confirm that the cryptocurrency exchange that owns Tether has invested in: an online betting site called Betfinex; Dazaar, a data sharing service; Dusk Networks, a software that converts financial investments into tokens; a cryptocurrency trading platform called Rhino; Shape Shift, a cryptocurrency wallet; blockchain infrastructure company Blockstream; digital ID company Netki; and video chat app Keet.io. Any honest assessment of this $2.6 billion “other investment” portfolio could mean it's worth less today than it was in September. As token holders wanted their money back, Tether had to sell everything it could sell — government bonds, corporate bonds, money market positions. This means that what it can't sell — that is, venture capital — will start to take up a larger portion of its assets. This is the beginning of bank overcrowding. Tether fell to $0.98 last month after cryptocurrency exchange FTX went out of business, forcing its chief technology officer to confirm that the company was returning hard currency to token holders who had requested it. “No problem...

“Ethereum killer” Solana climbed the Bitcoin wave and rose 8% in a single day, locking in a record high of $12.7 billion in total value

“Ethereum killer” Solana climbed the Bitcoin wave and rose 8% in a single day, locking in a record high of $12.7 billion in total value

After Bitcoin and Ethereum hit record highs this week, the smart contract blockchain Solana is slowly returning to its all-time high. According to data from the comparison terminal, SOL is the sixth-largest cryptocurrency by market capitalization. It has risen 27% in the past week and has risen more than 8% in the past 24 hours, returning back to the record area just set last month. It is now trading at $186.54, which is 12% lower than the all-time high of $213.47 set on September 9. This can be attributed in large part to Solana's pursuit of a larger decentralized finance (DeFi) market, which originated with Ethereum. DeFi refers to a protocol built on blockchain that allows people to put their cryptocurrencies to use without going through a third party. They can take loans, earn interest, exchange tokens, or perform other financial transactions. Just today, the total value of Solana locked on the network reached a record $12.7 billion. The indicator looks at how much money is flowing on Solana-based platforms. This number affects the price of SOL. Just as you need arcade tokens to play Pac-Man, Rampage, or Donkey Kong, you also need SOL to take advantage of its DeFi ecosystem. Solana's value proposition is that it's faster than Ethereum, which can process around 15 transactions per second. Solana has reached industry-leading speeds, processing 65,000 transactions per second, in part because Ethereum was not designed with specific use cases in mind, and Vitalik Buterin wanted to allow a wide range of applications to take root on the network. In contrast, Solana focused on DeFi from the beginning and was designed to handle the necessary transaction load to speed up the operation of decentralized finance. Of course, this requires a balance. Ethereum is still a more decentralized network in terms of the number of machines connected to the network; this is a good thing from a security perspective. Last month, Solana experienced a massive network outage due to issues with the network validator, which suggests that its high prices and low transaction costs could be costly. In Solana, nodes can create their own timestamps and send them to other nodes that can quickly verify their accuracy. So you don't have to wait for all these confirmations before continuing. Because Solana is so fast and scalable, they don't require any sharding or second-tier solutions Ethereum requires. This is a huge benefit because it's much simpler for developers to build directly at the top level rather than dealing with different shards or integrating with second-tier solutions. You need talented developers to build valuable apps on your blockchain for long-term success. But at this point, Solana has made some strange decisions that may prevent it from attracting as many developers as possible. For example, you need to write smart contracts in the Rust programming language, but not many developers know Rust. Another obstacle is that Solana's smart contracts aren't EVM compatible, which means that all DAB on the Ethereum network can't be easily transferred. Another important statement is that Solana has solved the blockchain trilemma. The blockchain trilemma is a concept where you have to make some trade-offs when it comes to the security, speed, and decentralization of any given blockchain. The idea is that you have to choose two and then sacrifice the third one. Some people choose speed and security over decentralization, while others prefer a different mix. But Solana claims to be fast, secure, and decentralized at the same time. Of course, Solana is fast and secure. It's undisputed, but critics say it's not decentralized. Because you need expensive hardware that costs thousands of dollars to become a validator or block producer. The image above is an eco-map recently published by Solana. As can be seen from the chart, there are currently not many Solana ecosystem projects, but most of them are focused on infrastructure, and the applications are mainly based on mature external applications, and there are still relatively few local Solana-based apps. Overall, although the current infrastructure of the Solana ecosystem is not very complete, it has been able to support the normal development of the Solana ecosystem. Native project class on Solana...

How can blockchain be launched fairly or unfairly?

How can blockchain be launched fairly or unfairly?

Written by Nic Carter, founder of cryptocurrency data provider Coin Metrics Compiled by Zhan Juan Editor: Huang Peijian Statement: From a personal or professional perspective, I have no interest in starting a new cryptocurrency now or in the future. This article is mainly meant to be a thought experiment, not an endorsement of any particular project. I don't recommend nor condone the creation of any new base-layer cryptocurrencies. Foreword ASIC's role in the Proof of Work (Proof of Work) system has always been highly controversial. In the mature phase, ASIC enhanced the security of the network (by forcing miners to bet on the success of a protocol for a long time), but in the transition phase, the hardware makers that first built ASICs could almost monopolize the minting of new coins. This could create an informal minting tax—minting currency at a lower cost than the market price. Protocols that fork frequently also face this risk; developers have the ability to decide which PoW function the chain will move to, so they can monetize their influence on the protocol. This is probably a very hidden form of corruption that undermines the “impartiality” that PoW is known for. GPU-type blockchain chains also have a poor quality, which is “nicehash-able” (nicehash-able) for mining, and it can also be attacked by renting commercialized hardware for a short period of time. Because this hardware can be repurposed and can also be rented and sold, GPU coin miners don't need to be tied to it for a long time. Note: ASCI is an abbreviation for Application-Specific Integrated Circuit, or dedicated integrated circuit. Compared with common general-purpose chips such as CPUs and GPUs, the computing power and computational efficiency of ASIC chips are directly customized according to the needs of specific algorithms, so ASIC chips can achieve the advantages of small size, low power consumption, high reliability, strong confidentiality, high computational performance, and high computational efficiency. These questions fill my mind. In 2018, I began to think about how an ASIC type launch would work. Not because I'm interested in participating in a particular project, but because I think it's interesting to think about the trade-offs involved. This tweet represents my thoughts at the time: @nic__carter: Sooner or later (<12 months), we'll see a development team announce a PoW-type fair launch project, and that team will launch an ASIC chip specifically for PoW algorithm mining for this project. The details of the algorithm will not be revealed until the Genesis block. About a month later, Obelisk (a subsidiary of Nebulous) unveiled a plan to provide a commercial service called Launchpad, which would facilitate PoW-type launches using specially tailored ASICs. I'm putting my tweet above in this article to prove that I've been thinking about these ideas for a long time, and I'm not writing this article to provide “moral support” for any particular PoW-type startup. Most of this article was written a long time ago, but I didn't take it out because I thought the PoW launch was basically paralyzed, and people wouldn't be very interested in it. In fact, I misestimated the timing — in the 12 months after I posted that tweet, there were no such PoW-type launches as far as I know. However, I've noticed that several teams are currently considering a similar launch. So I think my thoughts on this issue might be valuable. It's not for the benefit of a particular team, but because this kind of thinking provides us with an interesting context to evaluate some of the key issues in social scalability and security of these network projects, whether it's Bitcoin or another PoW chain. If anyone is planning to launch a new public blockchain, I'm convinced that PoW without pre-mining is the best way to achieve it. There are many reasons, and I'll cover them below. But I think GPU-style booting is getting more difficult and risky. I can't stop anyone from starting a certain chain. But I think a thorough analysis of the trade-offs can encourage teams to act more responsibly, or at least explore other parts of the project design. Finally, my thoughts on how to launch a new general-purpose blockchain might be unsettling to some. If you...
