How many levels of exile can mine
at present, Ethereum blockchain has exposed three major problems, and its founder vitalik
buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied
20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.
On September 2, it was reported that on August 21, the central bank headquarters received the relevant emergency report. The report analyzed in detail and clearly pointed out that from the perspective of penetrating supervision with substance more important than form, ICO belongs to illegal fund-raising in disguise
according to the lover quoted, relevant people of the central bank have studied a large number of ICO white papers and come to the conclusion that "90% of ICO projects are suspected of illegal fund-raising and subjective and intentional fraud, and less than 1% of the ICOS that actually raise funds for project investment."
what is the development history of ICO
July 2013: mastercoin (now renamed mastercoin Omni) is one of the first blockchain projects to carry out ICO. It successfully raised 5000 BTC in bitcointalk forum. Mastercoin is a second-generation token based on bitcoin protocol, which aims to help users create and trade cryptocurrency and other types of smart contracts
March 2015: Factom innovates the data management and data recording methods of commercial society and government departments by using bitcoin's blockchain technology through konify platform ICO
March 2016: lisk's decentralized application (dapps) uses JavaScript language for programming, which is the simplest and most popular programming language in the world. Lisk raised a total of 14080btc and more than 80 million XCR this time. The amount of crowdfunding ranked second in the ICO of blockchain project, second only to Ethereum
may 2016: the Dao is the largest crowdfunding project in the history of ICO, with a financing amount of US $160 million. The full name of Dao is decentralized autonomous organization, which can be understood as a company like entity completely controlled by computer code. It is the first time in human history. But ICO project, which attracted a lot of attention, was attacked by hackers, and then split between hard and soft in the debate, and finally ended up with disbanding and returning Ethernet money
September 2016: firstblood combines the electronic competition service with the blockchain, and uses the smart contract to solve the problem of reward structure. Crowdfunding raised US $6 million at the beginning, with a total of 465312.999eth in the world
it seems that there is a hint of a plot,
and then go to the mine entrance,
another little plot,
and then pay the money
. 1. Set the working mode to "MDI" mode< 2. Press the program key< 3. Press the "MDI" key at the bottom of the screen< 4. Input speed and steering (e.g. "s500m03;") Then press "insrt")< 5. Press the start key< Meaning: determine the coordinate origin of the workpiece in X and Y directions
2. Determination of the origin of X and Y planes< 1. Four sides dividing
2. Two sides dividing, one side touching
3. One side touching number
3. Copy number
1. Meaning: input the mechanical value after dividing into the workpiece coordinate system, so as to establish the position relationship with the coordinate origin of the machine tool< 2. Method:
→ switch to workpiece coordinate system: ofs / set → coordinate system → select specific workpiece coordinate system (such as g54, G55, g56, G57, g58, G59, etc.) → input "x0" and press the "measurement" key at the bottom of the screen (or directly input the mechanical coordinate value)
4. Type of sub center
0.1. Four side sub center
0.2. Number of single side collision
0.3. X-axis sub center, Y-axis sub center, X-axis sub center, X-axis sub center
0.5. Determination of offset workpiece origin, such as x30y20
5. Method of sub center
, 2 5000 treasures, 7 or 8 diamonds, 3 1000 dolls, 3-level backpack, full-scale fishing rod, 10 + 2 or + 3 fishing food, and more than 10 ts
this project was achieved by completely abandoning planting, mining, and super good luck
when I went to finish the task the next day to get the fishing rod, I fished directly at the starfish fishing spot on the beach, and opened nearly 20 boxes a day!! I went home at night and went fishing at Level 3. And I had bad luck that day.
1.
photoelectric inction type, which is relatively simple to use. The hand wheel is slowly close to the edge of the workpiece at the speed of 0.01mm, and the light will be on when touching it
2.
when using this kind of mechanical edge searching type, it should be noted that the rotation speed of the spindle is not more than 1000 revolutions, the hand wheel first approaches the edge of the workpiece at a speed of 0.1 mm, and the lower part will be eccentric when it touches the part. At this time, it will retreat 0.1-0.2 mm, and then lean towards the edge of the workpiece at a speed of 0.01 mm.
