Calculation force of side chain

1. Difference
bitcoin: an application based on blockchain technology, with limited total amount, decentralization, and the use of distributed bookkeeping technology. Data cannot be tampered with. The price fluctuates with the secondary market
q-coin: Tencent's virtual coins are unlimited and centralized. The price is relatively fixed
contact
q-coin and Bi, especially the virtual currency, which is different from legal currency. To sell bitcoin, you need to go to the virtual currency exchange. To sell q-coin, you can go to the q-coin consignment platform.

2. The main chain is the underlying technology foundation of all blockchain applications, just like chips and operating systems. Whoever can become the main chain of the basic layer of the blockchain and accumulate a large number of users and scenes is likely to become the future giants such as apple and Microsoft
however, for most scenarios of using and developing blockchain, it is not necessary to re create a set of blockchain, as long as we develop our own applications based on the existing underlying blockchain or technical framework. Therefore, for the similar encryption algorithm, P2P technology, consensus algorithm, we only need to have a basic understanding, and do not need in-depth study
the primary goal of blockchain application development is to find a relatively mature underlying blockchain for application development. The underlying blockchain needs powerful and easy-to-use development interface or framework, scalability, transaction frequency, etc
Rong technology is a listed financial technology company, which currently provides main chain construction and development services http://www.erong.com/new/blockchain/backbone/index.html

The current development stage of blockchain Technology: financial value period, credit value period and governance value period. Among them, blockchain 3.0 and 4.0 are developing rapidly. It is predicted that there will be a wave of great changes in blockchain technology

ecology makes the main chain and the side chain

ecol ecology makes the team deal with the difficulties faced by the side chain. Through data isolation and cross chain audit, the business data confidentiality and security of the side chain can be guaranteed, and the balance between data transparency and business confidentiality can be solved

and support multi side chain, main side chain communication, asset transfer, both integration and division of labor, both security and convenience. The main chain is mainly responsible for security and consensus. The side chain will provide smart contracts, token issuance, asset trading, cross chain interoperability, and the structure of the main and side chains. Through slimming and pruning technology, it can effectively prevent block swelling, garbage accumulation, and shorten synchronization time. To clear the obstacles for the implementation of high concurrency and lightning network

ecol ecol makes it possible to connect different blockchains through side chain technology, which is the key to solve the problem of slow transmission speed and low efficiency in expanding the external structure of blockchain. In short, the side chain is like a channel, connecting different blockchains together to realize the expansion of blockchain. In the long run, ecolink will graally build a high-speed value Internet belonging to the side chain in the case of developing, applying and proposing solutions

When calculating the isoelectric point, we should first write out the process of amino acid electric property from the most + to the most -, such as glutamic acid, from NH3 + (acooh, R-COOH) to NH3 + (Acoo -, R-COOH) to NH3 + (Acoo -, r-coo -) and finally to NH3 (Acoo -, r-coo -)

The NH3 + (Acoo -, R-COOH) generated in the second step is an amphoteric ion with zero electric property. When calculating the isoelectric point, it is obtained by dividing the sum of the left and right pK values of this ion by 2

There is something missing in the title, which should be PK1 (- COOH) = 2.19. pK2-NH3+=9.67 pK3R-COOH=4.25 These three pK values correspond to the first step, the third step and the second step respectively. The distinguishing method is to see which step proces a carboxyl group, or positive amino group, or side chain carboxyl group in brackets on the left or right

At last, pi = (2.19 + 4.15) / 2 = 3.22

{rrrrrrr}

extended data:

isoelectric point: pH of medium when an amino acid is in the state of facultative ion with zero net charge, expressed by pl

The isoelectric point of an amino acid with only one amino group and one carboxyl group can be calculated by using the acidity coefficient of the molecule

that is: pi = (PK1 + PK2) / 2, but more accurate calculation requires more in-depth knowledge of acids and bases

The dissociation degree of carboxyl group of neutral amino acid was higher than that of amino acid, so its pI value was slightly less than 7.0; The dissociation degree of carboxyl group of acid amino acids is greater, and PI is less than 7.0; The dissociation degree of amino group of basic amino acid is obviously greater than that of carboxyl group, so its Pi is greater than 7.0; Under a certain pH condition, the dissociation degree of amino group and carboxyl group is equal, and the static charge is zero. At this time, the pH of the solution is its isoelectric point

5. In BKO cross chain project, each single peptide chain is compatible and independent by default through the underlying structure of polypeptide chain, and the calculation power fluctuation ratio calculated by weighted average threshold value is directly converted by default through calculation power fluctuation ratio column ring single peptide token transfer, The token difference between BKO networks will be automatically converted to equivalent value when the token of single peptide chain is transferred. Even the token of different side chains can be automatically converted to equivalent value.

6. In the process of film proction, the most common problem is how to quickly match the volume of human voice and background music. The result we need is that when people begin to speak, the background music is lowered, and after they finish their
speech, the background music is raised again, so as to create a dynamic balance between the subject's expression and the background music.

7. Of course not! Didn't learn organic!? All of them

8. After learning the theory of covalent bond π 66 π Keyed π The bond electron cloud is conjugated with the P electron cloud of carbon to form P- π Conjugation, which makes the benzene ring and carbon atoms gather more closely, thus weakening the hydrocarbon bond and making h more active

9. R group refers to alkyl chain group, which is not the name of a group, but represents a group. That is, R group is a part of side chain group
