Bitcoin had a wild weekend, briefly topping $10,000, after China’s Xi sang blockchain’s praises
KEY POINTS
- Bitcoin’s price jumped as high as $10,332 on Saturday, according to industry site CoinDesk.
- Chinese leader Xi Jinping reportedly said China should “seize the opportunity” offered by blockchain.
- China’s central bank, the People’s Bank of China, has been working on its own digital currency.

Bitcoin’s price rose sharply over the weekend, recovering from a plunge just days earlier, after Chinese President Xi Jinping gave a speech embracing blockchain technology and calling on his country to advance development in the field.
The value of the world’s best-known cryptocurrency jumped as high as $10,332 on Saturday, according to data from industry website CoinDesk. The price has since eased to around $9,370 as of Monday morning, up about 1% on the day.
The virtual currency’s jump came as China’s leader sang the praises of blockchain, the technology that underpins cryptocurrencies like bitcoin. According to state media, Xi said Friday that China has a strong foundation and should look to take a leading position in the sector.
He reportedly said China should “seize the opportunity” offered by blockchain, adding the technology could benefit a range of industries including finance, education and health care. A blockchain is a digital ledger that maintains a record of transactions or other data across a network of computers.
Beijing has taken a tough stance on cryptocurrencies, banning a fundraising exercise known as an initial coin offering and forcing local trading platforms to shut down in 2017.
China’s central bank, the People’s Bank of China (PBOC), has been working on its own digital currency. It has accelerated its development in recent months as Facebook and a handful of other companies look to shake up the global financial services industry with a cryptocurrency called libra.
The PBOC set up a research team back in 2014 to explore the use of virtual currencies to reduce the costs involved in circulating traditional paper-based money. A senior official at the bank said last month that the planned digital token would bear some similarities to libra.
Libra has come under intense scrutiny from regulators around the world, who worry Facebook’s proposed digital asset would disrupt the financial system and could be open to risks like money laundering and terrorist financing.
Lawmakers last week grilled Facebook CEO Mark Zuckerberg over the project. Zuckerberg at one point said the social network would not take part in launching libra “until U.S. regulators approve.”
Though Facebook has led the initiative so far, the tech giant has been trying to keep a distance between it and the Switzerland-based Libra Association that oversees the currency’s development. The consortium lost key initial supporters including Mastercard and Visa earlier this month, leaving it with just 21 founding members.
Bitcoin has been on the rise this year and is currently up nearly 150% year-to-date. That marks a significant turnaround from last year, when the digital coin tanked to as low as $3,122 after hitting an all-time high of close to $20,000 in December 2017.
Analysts had attributed some of the cryptocurrency’s 2019 gains to headlines around companies like Facebook, Fidelity and New York Stock Exchange owner Intercontinental Exchange getting involved in the space, the logic being that it brings some much-needed legitimacy to an industry that has in the past been clouded by major cyberattacks and scams.

Philippines Hit by 6.6 Magnitude Earthquake - US Geological Survey
MOSCOW (UrduPoint News / Sputnik - 29th October, 2019) The Philippines was hit on Tuesday by a 6.6 magnitude earthquake, the US Geological Survey said.
The tremor was registered at 01:04 GMT on the island of Mindanao, 14 kilometers (over 8 miles) east of the settlement of Bual. The epicenter of the earthquake was located at the depth of 15 kilometers.�
There are no reports about any victims, or damages caused by the earthquake. No tsunami alert has been declared.
The Philippines is located in a seismologically active zone, known as the Ring of Fire, and often suffers from powerful earthquakes. The archipelago lies along the border between the Philippine Sea Plate and the Eurasian plate, which are colliding and increasing the seismological activity in the area.
The 1976 Moro Gulf earthquake, which caused a powerful tsunami, is the deadliest recorded earthquake in the history of the Philippines, which left from 5,000 to 8,000 people dead.

Introduction to OSI Model vs TCP/IP Model
Both, OSI vs TCP/IP are the most popular and widely used communication networking protocols. The main difference between them is that OSI is a conceptual model that is not practically used for communication. It defines how the data is transferred in a network or different architectures. Whereas TCP/IP is widely used for link establishment and network interaction. The TCP/IP also allows the connection mode on the network layer only, but these two methods are on the transport layer. With the OSI model, it promotes connection-free and connection-oriented network communication, but connection-oriented communication is only permitted in the transport layer.
OSI Model:
The OSI Model is a conceptual model developed by the International Organization for Standardization that allows various communication systems to communicate through standard protocols.
- Application layer: This is the only layer that interacts directly with user data. However, it should be noted that software applications are not components of the application layer; the application layer is accountable for protocols and information manipulation on which the software users are relying to obtain significant information.
- Presentation Layer: The primary task of this layer is to prepare the information so that the application layer can be used, that is to say, that layer 6 makes the information available for consumption apps. Two communicators may use different encryption methods to communicate so that the incoming data is converted to a syntax which the receiving device application layer can understand.
- Session layer: This is the layer used to open and close the communication between the two machines. The period between the opening and closing of the correspondence is known as the session.
- Transport Layer: Flow Control and error control is responsible for this layer. The transportation layer checks the receiving end for errors in ensuring the completeness of the received data and requests retransmission if not.
- Network Layer: The network layer allows the transfer of information between two distinct networks. The network layer also identifies the best physical route for the information to reach its destination.
- Data Link Layer: The data link layer collects packets from the layer and breaks them into smaller parts. Like the network layer, the flow control and error control in interconnected communication is responsible for the data link layer.
- Physical Layer: This layer contains physical devices, such as wires and switching, involved in information transfer. This is also the string of 1s and 0s, where the information becomes a bitstream.
TCP/IP Model:
Internet Protocols are the rules set established for network communication. TCP/IP is considered a robust networking protocol model. It is the condensed version of the OSI Model.
- Network Access Layer: Network Access Layer is the combination of Data Link Layer and Physical Layer available in the OSI model. Physical Addressing is done in this layer i.e. MAC Address of source and destination is assigned to the data packets. Hence this layer is responsible for the physical transmission of data.
- Internet Layer: The Internet layer is used to send an independent packet to a network to the destination. All the machines, Web servers, nodes that are attached to the TCP/IP network are assigned in this layer.
- Transport layer: It allows the information to be delivered in information chart format from the source to the destination host without defects.
- Application Layer: Application layer performs the tasks of the OSI model in three layers: Application, Presentation and Session Layer. It is required for the interaction between node and node and handles the requirements of the user interface. Protocols available in the Application Layer are TFTP, HTTP, Telnet, SSH, NTP, DNS, NFS, FTP, SNMP, DHCP, SMTP.
Head to Head Comparison between OSI Model vs TCP/IP Model
Below are the top 7 differences between OSI Model vs TCP/IP Model.
Key Differences between OSI Model vs TCP/Ip Model
Let us discuss some of the major differences between OSI Model vs TCP/IP Model
- The horizontal approach is known to the OSI and the vertical approach is called the TCP/IP approach.
- OSI is protocol-independent and generic, while TCP/IP has normal laws that support Internet development.
- As compare to OSI model TCP/IP model is more reliable
- Packages are supplied to the OSI transport layer whereas in the event of TCP/IP this is not sure.
- In the OSI model, a presentation and session layer is available while the TCP/IP model does not contain such a layer.
- TCP/IP implements the features that operate the system, OSI helps guide the network and serves as reference tools
- TCP/IP offers network-level connectivity facilities whereas the OSI network layer offers both connection and connectionless services.
- No other model is TCP/IP, while OSI is attempting to match other model designs because it is a reference.
- Protocols can be easily terminated, while the original rules are in the TCP/IP model, new can be introduced in the OSI model.
OSI Model and TCP/IP Comparison Table
Let us discuss the topmost differences between OSI Model vs TCP/IP Model.
| OSI Model | TCP/IP Model |
| It stands for Open Systems Interconnection | It stands for Transmission Control and Internet Protocol. |
| It is a theoretical framework for the computer environment. | It is a customer service model that is used for data information transmission. |
| In the OSI model, there are 7 Layers | 4 Layers are present in the TCP/IP model |
| Low in use | TCP/IP model is mostly used |
| This model is an approach in Vertical | This model is an approach in horizontal |
| In this model delivery of package is a guarantee | In this model delivery of package is not assured |
| The protocol is hidden in OSI and can be easily substituted and changes in technology. | In this model replacing tool is not easy as like OSI |
Conclusion
In this article, we have seen differences between the OSI Model vs TCP/IP Model. TCP/IP is widely used to convey the information via the internet from beginning to end. Hence we can conclude that TCP/IP is more robust, flexible than the OSI model and also indicates how information should be transmitted over the Internet.

Anatomy of a raid: How US took out Baghdadi
The United States began to receive intelligence on the whereabouts of Baghdadi around a month ago and were able to "scope out" his exact location two weeks ago, while Prez Trump became aware of the planned raid three days ago. While the US secured permission from Russia, Iraq and Turkey to fly over their airspace, the nature of the operation was not revealed.
PM flight denial: India takes Pak to world body
India has taken the matter of Pakistan's move to deny permission to PM Narendra Modi's special flight to use its airspace, to the International Civil Aviation Organisation, sources in the govt have said. Overflight clearances are sought and granted by other countries as prescribed by the ICAO guidelines. In September too, Pak had denied Modi access to its air space for his visit to the US.
