Bitcoin mining hardware ASIC

SecureEnclave (secure area) is a coprocessor integrated in AppleA7 (first integrated in iPhone5S to ensure the security of "touch IDBitcoin mining hardware ASIC") or higher version A series processors. It provides all data protection key management The encryption operation can maintain the integrity of data protection even when the kernel is compromised. And the key generated inside SecureEnclave uses a real hardware random number generator.

According to a report recently released by Nobuaki Kobayashi, the trustee of Mt.Gox, there are still about 2.1 billion U.S. dollars in Bitcoin (110,000) and Bitcoin Cash (120,000) in the trustee’s account, which means the future of this custodian How to sell on a large scale may still cause some pressure on the market.

"Despite the challenges, we believe that investors are worth looking into the field of cryptocurrency investment today. The dramatic decline in the cryptocurrency market has brought questions about the future development prospects of these assets and blockchain technology, but we see Until this industry is developing, not standing still,” Cambridge Associates wrote in a research report.

In addition to the public trust that replaces traditional legal contracts, blockchain can also provide smart contracts through enhanced applications in this field. A smart contract based on blockchain technology can provide certain automatic execution functions while protecting and screening the integrity and validity of the contract. Of course, the premise is that the execution conditions and execution channels of the contract can be pre-written on the blockchain and Embedded into the system.

We have not been able to find out where the 320,000 coins are going. Today’s hope is that any phenomenon is complicated, especially the news. Think about it, don’t be taken by the dog dealer. Rhythm, now the market price is good-looking, but there is FOMO sentiment in the middle, and still need to pay attention to safety.

In April 2014, GavinWood, the co-founder of Ethereum and the CTO of Ethereum at the time, published a blog post entitled "Decentralized Applications: What Does Web0 Look Like". The concept of Web3 was systematically explained for the first time. GavinWood believes that in the post-Snowden era, Internet users can no longer continue to trust companies, and companies will only manage and use user data for their own profitability purposes. Therefore, it is necessary to create Internet infrastructure and applications that minimize trust. GavinWood proposed that Web0 will be based on a new Internet technology stack, which mainly includes four modules: static content publishing, dynamic messages, trusted transactions and integrated interfaces. Users use untraceable anonymous identities (public key addresBitcoin mining hardware ASICses) to interact with Web3 applications, messages between users are encrypted end-to-end, and transactions are reached by a decentralized consensus engine, thereby eliminating intermediary costs and counterparty risks.

Innovation is hard work. Because you are trying to create something that exists theoretically but does not actually exist! There are no guidelines for innovation, no templates, and no business logic to clone. Nothing. Only you! With only you and your imagination, of course 90% of people and companies will fail!

From the perspective of Bitcoin's transaction volume per second, Ethereum's operations are better than Bitcoin. The maximum transaction volume of Ethereum is 20 transactions per second, which is almost three times that of Bitcoin. However, in essence, the blockchain of Ethereum is much busier than the blockchain of Bitcoin, because it can not only be used as a payment system, but it can also implement decentralized applications (dapp) and first-time coins. Issuance (ICO). The vast majority of ICOs rely on Ethereum, and the token sale will suddenly bring a lot of traffic to the Ethereum network, which will further slow down the transaction speed of the entire network. Therefore, such a busy Ethereum will need a scaling solution that can be adjusted to meet its needs, which seems to be normal but not too much. In fact, Ethereum has several different solutions, but one of them is particularly worthy of our attention: Raiden.

In addition to application-level challenges, blockchain has a fundamental limitation. The maintenance cost of public trust it provides is higher than that of traditional public trust. We can see from the application of Bitcoin that blockchain is not a technology that can be completely decentralized, but a distributed centralization technology. Although it does not rely on the existence of a single central server, it has to provide corresponding block generation and maintenance services for the members participating in the chain through the continuous competition and cooperation of multiple servers. The maintenance of this high-cost partnership is a district. A necessary condition for the existence of a blockchain, so the minimum economic cost threshold required to maintain a blockchain limits the possibility of converting more traditional public trust fields into blockchain applications.
