Bitcoin data layer 1MB

1. Triporg travel: a travel service application using blockchain, which provides booking services such as air tickets and train tickets.

2. The credit problem of central system

3. yes. In 2017, the size of the capacity hit this "invisible wall.". Soaring costs have made bitcoin unreliable. Some users can't confirm their transactions even after waiting for many days. Bitcoin stopped growing. Many users, businesses, enterprises and investors have abandoned bitcoin. Its market share in many virtual currencies also dropped rapidly from 95% to 40%.

4. One minute to understand the past and present of bitcoin expansion
at the beginning of the birth of bitcoin, Ben Cong, the founder of bitcoin, did not deliberately limit the size of the block. The maximum size of the block can reach 32MB
at that time, the average size of each block was 1-2kb. Some people thought that the upper limit of the blockchain was too high, which was easy to waste computing resources and prone to DDoS attacks. Therefore, in order to ensure the security and stability of the bitcoin system, Nakamoto decided to temporarily limit the block size to 1MB
at that time, the number of users of bitcoin was small and the transaction volume was not so large, which would not cause block congestion. Since 2013, the price of bitcoin has skyrocketed, with more and more users. The problems of network congestion and rising transaction costs of bitcoin have graally emerged
the bitcoin community began to explore how to "expand the capacity" of bitcoin, that is, to improve the transaction processing capacity by modifying the underlying code of bitcoin.

The size of 1KB is 1024 bytes, which is usually abbreviated as 1KB. 1MB is equal to 1024KB and 1 Megabyte at the same time, which is usually abbreviated as 1MB, while 1GB is equal to 1024MB, which is 1024 megabytes, which is usually expressed as 1GB. Up there are TB, Pb, EB, etc. the values converted from each other are 1024

the units of capacity from small to large are: byte (b), KB, MB, GB, TB. The relationship between them is

1TB = 1024gb

1GB = 1024MB

1MB = 1024KB

1KB = 1024 bytes

about mobile traffic

1. Mobile traffic refers to the traffic data generated by mobile Internet. When using mobile phone to open software or carry out Internet operation, it will exchange data with the server, and mobile traffic refers to the size of the data

2. An English word needs 1b, while a Chinese character needs 2B, and a picture usually needs several KB. Generally speaking, the web pages on mobile phones are tens of KB / page, that is tens of thousands of KB

6.

One megabyte, a unit of storage in a computer

In terms of information byte, 1 Megabyte = 1MB = 1048576 bytes, M is the abbreviation of mega, which means millions or megabytes, and B is the abbreviation of byte, which means bytes

1g is equal to 1024MB, 1MB is equal to 1024KB, B is byte, K is kilo, and G is Giga

MB or MIB can be mebibyte, that is, 220 = 1048576 bytes (byte) megabyte, or 106 = 1000000 bytes (byte)

extended data:

the difference between MB and MB is that the transmission rate of general data machine and network communication is based on "BPS". Upper case B stands for byte and lower case B stands for bit

such as 14.4 Kbps, 28.8 Kbps, 56 Kbps, 1.5 Mbps, 10 Mbps, etc. take 1m broadband as an example, 1Mbps, etc. such as 1x 1024 / 8 or 128KB / s, but the above speed is only the highest speed in theory

the maximum speed is about 87kb / sec e to subtracting about 30% of the network loss of Ethernet header, TCP header and ATM header from the actual application

1MB = 1024KB

MB full name Mbyte, a computer storage unit read as "megabyte"

data unit MB is different from MB, Mbyte means "megabyte", Mbit means "megabit". Mbyte is the number of bytes, Mbit is the number of bits. Although "byte" in Mbyte is the same as "bit" in Mbit, both are bits and data measurement units, they are completely different

In most computer systems, a byte is an 8-bit data unit, and most computers use a byte to represent a character, number or other character. A byte can also represent a series of binary bits

in some computer systems, four bytes represent a word, which is the unit that the computer can effectively process data when executing instructions. Some language descriptions require two bytes to represent a character, which is called a double byte character set

some processors can handle double byte or single byte instructions. Bytes are usually abbreviated as "B", while bits are usually abbreviated as lowercase "B". The size of computer memory is usually expressed in bytes

8. MB (full name Mbyte): a unit of storage in a computer, read as "megabyte". Data unit MB and MB are often mistaken for the same meaning. In fact, Mbyte means "megabyte", Mbit means "megabit". Mbyte is the number of bytes, Mbit is the number of bits. Although "byte" in Mbyte is the same as "bit" in Mbit, both are bits and data measurement units, they are completely different. Byte is the "number of bytes" and bit is the "number of bits". In a computer, every eight bits is a byte, that is, 1byte = 8bit, which is the corresponding relationship of 1:8. Therefore, when writing units, we must pay attention to the case and meaning of B letters< The conversion unit of MB is:
1MB = 1024KB
we abbreviate it as
1m = 1024k
the unit larger than m is g, the unit smaller than m is k, and the multiple between them is 1024. The specific conversion relationship is as follows:
1t = 1g
1g = 1024m
1m = 1024k
1K = 1024b (bytes)
the units larger than GB are TB, Pb, EB, ZB Yb and so on, TB e to the capacity has been quite large, generally rarely encountered in the computer
as for the rookie friends who asked Xiaobian how big 1m is, in fact, it is a relative concept. For example, if the broadband we pull reaches 4m or higher, the network speed will be very good. Therefore, we can say that 4m is very good for home broadband at present. At least we can't use the card to watch high-definition movies on the Internet, so we can run all kinds of network applications smoothly; But if the size of a computer software is 4m, then we will definitely say it is a very small software, because the current common software size is dozens to hundreds of M, or even several G, so compared with the software size, 4m is indeed very small, so I want to say how big 1m is a relative concept
about how much KB is 1m? I believe you can casually say it's 1024KB. In fact, it's very simple. It's just a concept. This article is suitable for novices and experts.

9. 1.28mb = 1310kb

you can get the next wma format music, which takes up less memory, of course, the sound quality is poor

generally, the 240 * 320 size picture is tens of KB

10. The computer's data storage space is binary, that is, on and off. A status is 1 bit (bit, usually represented by lowercase b), and 8 bits is 1 byte (byte is represented by upper case B, 1 English letter is 1b, and a Chinese character is 2b). K stands for thousands, m stands for megabytes, and G stands for gigabytes. Generally, the base of upper case K, m, and G is 1024, while lower case K, m, and G are 1000, respectively, 100000 and 1000000000, For example, the code rate of MP3 is 128kbps, which means that the amount of data per second is 128kbps.
from large to small:
1dB = 1024 NB
1nb = 1024 Yb
1yb = 1024 ZB
1zb = 1024 EB
1eb = 1024 Pb
1PB = 1024 TB
1TB = 1024 GB
1GB = 1024 MB
1MB = 1024 KB
1KB = 1024 byte
1byte = 8bit
MB, Megabytes
usually 1 Megabyte = 1000KB.
