Cloud Mining 2022

If you are thinking of mining Bitcoin and other cryptocurrencies in 2022, you will most likely prefer cloud mining rather than going through the tedious and overly expensive in-person setup of mining rigs and specialized software.With the great bull run that started in late 2020, so much attention was given to Bitcoin again. One of the many ways to earn cryptocurrency passively is by investing in cloud mining on legitimate platforms like Hashpower Foundation.

Keuntungan & Kerugian Investasi Cryptocurrency
Cryptocurrency adalah coin yang saat ini sedang melambung namanya, jual-beli cryptocurrency mulai banyak bermunculan di dunia maya, seperti bitcoin, ethereum, rippel dan lainnya. Harga yang fluktuatif membuat tingginya minat orang untuk melakukan jual-beli cryptocurrency, berbeda dengan saham yang hanya mendapatkan hitungan persentase saja. Cryptocurrency menganut system peer to peer sehingga siapa saja bisa melakukan jual-beli dengan syarat bisa melakukan kelengkapan KYC. Berbagai situs bisa anda gunakan mulai dari Binance, Tokocrypto, Indodax, Pintu, Luno. Semua exchange ini mengikuti harga yang sebenarnya. Anda bisa memilih cryptocurrency sesuai keinginan, karena tidak ada batasan untuk membelinya asalkan anda mengerti keggunaan coin tersebut untuk apa. Oleh karena itu, banyak orang yang belum paham keuntungan dan kerugian ketika melakukan jual-beli cryptocurrency, agar anda bisa paham perhatikan ulasan berikut! Keuntungan Investasi Cryptocurrency 1. Potensi Kenaikan Harga di Masa Mendatang Sudah sering Anda dengar bukan, bitcoin dan mata uang digital lainnya sudah membuat puluhan orang kaya raya mendadak. Trend yang meningkat dengan luar biasa adalah bukti otentik di masa lampau. Bagaimana di masa depan? Bahkan penyihir pun tidak akan bisa meramal dengan tepat, tapi belajar dari pola yang ada, maka potensi kenaikan nilai bitcoin di masa mendatang bukan kemustahilan. 2. Kebebasan dan Kecepatan Bitcoin, ether, dan mayoritas mata uang kripto lain menggunakan teknologi blockchain tanpa melibatkan pihak ketiga yakni perbankan. Dengan demikian, tidak ada aturan-aturan yang berpotensi menghambat proses payment. Misalnya ketika melakukan transfer ke luar negeri, maka prosesnya tidak perlu menunggu hari kerja, tapi cukup dengan hitungan jam bahkan menit. Kenapa bisa semudah dan secepat itu? Karena pada prinsipnya, tujuan awal penciptaan mata uang kripto adalah untuk menghilangkan hambatan-hambatan di dunia keuangan. Meskipun saat ini, berbagai startup mulai melirik menerbitkan mata uang kripto sebagai sarana crowd funding melalui ICO. 3. Keamanan Identitas Di dunia ini, ada saja orang yang memiliki kebutuhan aneh, macam menyembunyikan identitas ketika bertransaksi. Eits, jangan negative thinking dulu dah ah! Bisa jadi karena ogah info personalnya diketahui Bank atau oleh merchant. Info semacam itu berharga dan rawan disalahgunakan lhoh. Maka dari itu, beberapa orang memilih menggunakan BTC dan ETH untuk menjamin informasi yang ada. Tapi jangan digunakan di Indonesia, dilarang ntuh buat jual beli. 4. Menghindari pemalsuan uang Salah satu problem dari penggunaan duit kertas maupun kartu kredit adalah rawan pencurian dan pemalsuan. Secara teknis di dunia digital, ada istilah “double spend”, yang bermakna dengan menggunakan uang yang sama, seseorang melakukan transaksi untuk dua hal yang beda. Skema blockchain di mata uang kripto tidak memungkinkan hal ini terjadi, bisa dibilang aman! 5. Berpartisipasi dalam ICO Sudah tau apa artinya ICO? Pernah loh saya tulis tentang Initial Coin Offering. Dimana perusahaan yang punya proyek, nerbitin mata uang digital untuk membiayainya. Nah hebatnya, banyak ICO membuat orang menjadi kaya karena proyeknya berjalan dengan lancar sehingga nilai koinnya meningkat luar biasa drastis. Kita pake contoh lagi deh. Misal proyek X menerbitkan Xcoin dengan harga ICO USD 0,01 per token(coin). Kemudian dalam setahun harganya meningkat menjadi USD 1 per koin. Naik 100 kali lipat dong! Terus apa hubungannya dengan mata uang digital lainnya? Saat ini, sebagian ICO minta BTC atau ETH untuk Anda yang mau berpartisipasi dalam proyek mereka, bukan melalui transfer duit konvensional. Itulah kenapa, paling tidak harus memiliki mata uang kripto kalo mau berpartisipasi dalam ICO. Kerugian Investasi Cryptocurrency 1. Volatilitas Sangat Tinggi Heiy, di intro kan sudah saya jelaskan masalah volatilitas ini! Jadi sabar saja ya, mudah-mudahan lekas ketemu nilai wajarnya. Jadi investor dan company yang mau ICO bisa tenang gembira. Nah, tapi Anda juga tidak boleh abai terhadap beberapa poin lain yang berpotensi mengganggu investasi kita. 2. Potensi pelanggaran Hukum Masalah utama dan paling pelik yang dihadapi oleh mata uang digital adalah regulasi. Seandainya semua negara di dunia melarang bitcoin, bisa dipastikan nilainya akan runtuh dan tak berharga. Kenyataannya tidak bukan? Ini karena beberapa negara sudah mengatur dan mengijinkan penggunaan mata uang kripto. Bahkan Swedia dikabarkan sebagai negara pertama yang ikut menerbitkan mata uang kripto-nya sendiri. Saya sendiri melihat beberapa perusahaan keuangan global enggan menerima bitcoin dan semacamnya karena takut mengganggu bisnis yang selama ini telah dibangun. Eksekutif dari JP Morgan sampai melarang karyawannya beli bitcoin lhoh, dan itu menggelikan menurut saya. Jika permasalahan dengan regulator sudah usai, nampaknya peningkatan valuasi mata uang kripto tidak akan bisa dihindari. 3. Kehilangan “kunci” wallet Pastikan Anda mencatat di komputer atau kalau perlu di print dan disimpan di beberapa tempat. Karena apabila Anda lupa dan kehilangan kunci wallet Anda, maka akan sangat susah dan hampir mustahil bisa mengakses dompet Anda. Salah satu solusi yang menurut saya bisa dijadikan pertimbangan adalah menggunakan apps di handphone, tentu harus lebih user friendly dan mudah digunakan. Kali ini saya bekerja sama dengan Luno dan sudah mencoba keunggulannya sebagai wallet Bitcoin dan Ether. Nah jadi sembari nunggu perkembangan dunia per-kripto-an, Anda bisa mulai mendaftar ke Luno. Apakah harus Luno? Silakan Anda coba aplikasi yang lain dan pilih sesuai keinginan masing-masing. Tapi menurut saya, wallet Luno adalah salah satu yang paling aman! Tapi sebelum memutuskan mencari aplikasi lainnya, pastikan bahwa penggunaannya harus mudah dan secure. Apa gunanya Anda mendownload wallet jika ternyata tidak meminimalisir kemungkinan kehilangan token cryptocurrency.

5 Industries Where Blockchain Can Unlock New Value
In this technological world, we cannot deny the importance of blockchain. Blockchain technology has become the most popular because of its security and privacy in almost every sector, especially in healthcare, energy, government, sports, and eCommerce. Are you wondering why blockchain technology is gaining popularity across a wide range of industries? In this blog, we’ll cover 5 industries where blockchain plays a crucial role. First, let's discuss what blockchain is and how it works before we discuss its importance in different industries. Continue reading this blog! What is a Blockchain and How Does It Work? A blockchain is a form of digital ledger technology that stores data of any kind. For example, a blockchain can store information about cryptocurrency transactions, NFT ownership, or defi smart contracts. Moreover, blockchain can secure data in complete confidential form without any error or negligence. Therefore, the record of any organization about their confidential content can be kept secure for a long time. 5 Industries That Will be Disrupted by Blockchain 1: Banking, Insurance and Finance: Blockchain technology is highly in demand in the banking, insurance, and finance sector. There are many benefits of blockchain technology for both organizations and clients. It is easy for clients and account holders to access their accounts from home. In blockchain technology, the transaction data is secured in proper confidential form, so there is no chance of fraud or mistake. 2: Energy: The energy industry is also heavily regulated, so industry players need to ensure compliance with the regulation on a regional and global level. Another challenge stems from the growing need to support clean energy and sustainability. Blockchain in energy is perfect for addressing many of the industry's problem areas. 3. Pharmaceuticals: Blockchain technology also plays a vital role in Pharmaceuticals. For example, the healthcare department could use it to keep proper records of every patient, so it would be advantageous to use blockchain technology to improve the results of their hospitals, etc. In this way, a doctor can easily access the data or records of every patient, and there is no chance of any mistake or error in the treatment of the relevant patient. As well as blockchain technology is helpful for patients because they can get updates on their reports in time at their homes. 4. Real Estate: Blockchain technology is beneficial in real estate, as all the transactions are kept recorded in the blockchain, so there is no chance of any fault or error. Land ownership is also kept recorded in the form of data which is very helpful in the future. In blockchain technology, the property documents can easily be transferred from one person to another in the best confidential way, so there's no need for any third party. 5. Government: Blockchain technology is also valuable for government sectors. This is the new digital era, and blockchain is the basic need of this era, not just in the government sector but also in all sectors of life. For example, with the help of blockchain, the government organization can keep storing every employee's data in a proper confidential way. Blockchain is a revolutionary aspect of healthcare, real estate, sports, energy, etc., and we cannot deny the importance of blockchain in this new technological world.

Study of Smart Contracts: Concept and Evolution
What is a smart contract In 1996, Nick Szabo proposed the concept of smart contracts in the article “Smart Contracts: Building Blocks For Digital Markets”. The so-called “contract” is something like a clause or a contract, which records the conditions of occurrence and the corresponding executed clauses to support operations such as confirmation of rights; the so-called “intelligence” means automation and programmability. Therefore, Bridge Smart Contract Development Services is a programmable contract, and it can also be understood as a self-executing clause contract. In a computer, it is a self-executing program fragment. It is easier to save the contract, and it is run by a certain algorithm. Given the input, the corresponding output is obtained, which greatly guarantees the execution of the contract. Using the vending machine analogy can help us better understand the core features of smart contracts. When the user selects the goods to be purchased and completes the payment, the shipping logic will be triggered, and the user can get the desired goods, and this process does not require manual intervention, which saves the labor cost of selling goods. If you want to break this contract, you have to physically destroy the vending machine. Like POS card swiping machines, EDI (Electronic Data Interchange), etc., this analogy can also be used. Smart Contracts and Blockchain Smart contracts were proposed in the last century, while blockchain was born in 2009. By definition, smart contracts have little to do with blockchain. So why have smart contracts and blockchains been so closely related in the past 10 years? Because the blockchain can ensure that the smart contract cannot be tampered with, not only the contract content cannot be tampered with, but also the record of each call. The most basic premise for smart contracts to generate value is to have a strong underlying medium for storage, so that it cannot be physically damaged. However, the ontology of a smart contract is a piece of code, which is very easy to be tampered with, and how to provide a strong storage medium for it becomes a problem. This is exactly what the blockchain is good at solving — through the practice of Bitcoin, Cross chain bridge development it has been proved that the blockchain can make electronic records immutable in a distributed environment. At the same time, smart contracts are also feeding the blockchain, which greatly expands the business scenarios of the blockchain. After being combined with smart contracts, the blockchain no longer serves a single currency payment, and can be extended to all aspects of life. The rich application scenarios also pose new challenges to the capabilities of the blockchain. Blockchain 2.0: The Birth of Ethereum Bitcoin, born in 2009, uses technologies such as blockchain to ensure the ecology, creating the era of blockchain 1.0. Users can customize some things through script code, such as how to unlock a fund. These script codes are saved with the transaction, thus enjoying immutability and determinism. So from a certain perspective, these scripts can also be regarded as smart contracts. But they don’t work well. First, these script codes are not Turing-complete, which limits the functions that can be implemented; second, the development threshold is high, and the experience of writing complex logic will be poor, such as writing programs with JVM bytecode. In 2013, a young goddess Buterin proposed Ethereum, the core of which is to update and verify blockchain data through the state of the world. The biggest difference between Ethereum and Bitcoin is that complex logical operations can be performed through smart contracts. On Ethereum, the language of smart contracts is Solidity, Build a cross chain bridge which is a Turing-complete and relatively upper-level language, which greatly expands the capabilities of smart contracts and reduces the difficulty of writing smart contracts. Because of this, the birth of Ethereum also marks the beginning of the blockchain 2.0 era. Subsequently, smart contract technology has gradually penetrated into multiple business scenarios such as traceability, certificate storage, and supply chain. Status and Prospects of Smart Contracts From a programming perspective, a smart contract is a piece of code. Smart contracts have many differences and limitations compared to regular code, such as: single thread execution Code execution consumes resources and cannot exceed resource limits It is currently difficult to obtain off-chain data, such as weather information, game results, etc. Other restrictions like TPS These characteristics make the current smart contract ecology center on the governance of on-chain resources. Just like various ERC standards and governance schemes on Ethereum; there are various resource models on EOS, such as CPU, RAM, concurrent economic model, Rex, Bancor protocol, etc. Obviously, as far as the current ecology is concerned, the influence of smart contracts on the real world is limited. But things are always evolving. At present, there have been many researches devoted to breaking these limitations, typically Oracles (oracles, but often referred to as oracles), which allow smart contracts to interact with off-chain, which can greatly improve the use of smart contracts In the scene, it seems that a computer is connected to the Internet; for example, those attempts to break through the performance bottleneck of the chain itself, such as payment channels, cross-chain, plasma, and rollup, all break the shackles of security and performance from different angles. Undoubtedly, smart contracts will play an increasingly important role, and with the implementation of Ethereum 2.0 in the future, a new blockchain era may be opened. Smart Contract Technology Ethereum adopts Solidity as a smart contract language, Solidity is a high-level programming language created to implement smart contracts that can run on nodes that allow Ethereum programs. The language absorbs some features of C++ and JavaScript, such as it is a statically typed language, supports inheritance, libraries, etc. In addition to Solidity, the smart contract technology of each platform is also different. Next, we will introduce the technologies adopted by other platforms from the public chain and alliance chain. Smart contract operation analysis The function of this Solidity code is to access the _num field. This field is called a “state variable” and is persistently stored by the blockchain. Users can deploy this code on Ethereum or similar blockchains. Successful deployment means that the smart contract can no longer be modified. As long as the underlying blockchain is not destroyed, the contract will always exist. Anyone can call the contract interface through the “contract address”, and the information of each call will be recorded on the chain. Before explaining how this code works, let’s review how a traditional java program works. First, after the user compiles the java code, Build a token bridge it will be saved on the disk in the form of bytecode; then the user will call the program, which is managed and executed by the JVM; during the execution of the program, the call parameters may be recorded through the log, and the Disk for IO. Solidity’s implementation is similar. The difference is that the medium is changed from hard disk to blockchain, and from stand-alone to distributed. After the code is deployed, it is stored on each node in the form of bytecode. When a user requests to call a function, the call request will be included in the transaction and packaged into a block. Once the entire network reaches a consensus on the block, it means that the call is legal. Next, the EVM will call the bytecode, which is responsible for accessing the underlying state variables, just like traditional programming IO. Epilogue This article introduces the concept and historical evolution of smart contracts. Smart contract is a technology proposed in the last century, which has radiated new vitality under the wave of blockchain. On the contrary, the extensive application scenarios of smart contracts have greatly promoted the development of blockchain. To learn smart contracts, it is recommended to choose Solidity language, because it has the characteristics of some traditional languages. At the same time, the execution environment is completely based on blockchain, and the actual business development experience will be different from the previous programming experience. Readers can try to quickly build a blockchain environment based on FISCO BCOS, deploy a simplest contract, become familiar with the deployment and invocation methods, and then further enter the world of Solidity.
