Bitcoin
Bitcoin (BTC) is the pioneer among cryptocurrencies. It is a decentralized, censorship-resistant digital currency based on blockchain technology. Any state or central bank does not regulate it. It is inflation-proof as the inventor Satoshi Nakamoto limited the absolute amount to 21 million.
How Does Bitcoin Work?
The decentralized structure of Bitcoin means that all transactions take place transparently within the Bitcoin network. To become part of the network, you need some “Bitcoin account,” which Wallet called.
The Wallet has a unique identifier and a cryptographic key pair (so-called “private key” and “public address”) and can be installed on the computer as well as on the smartphone.
The private key acts as a digital signature, a kind of password, to dispose of your Bitcoin in the blockchain. The public key serves as a public address (comparable to an email address) to which Bitcoins can send.
The Benefits of Bitcoin
The decentralized and tamper-proof architecture of Bitcoin makes intermediaries/middlemen, such as banks or credit institutions, sometimes excessive. This eliminates the expensive transaction costs that banks often charge their customers for international transactions.
All transactions have to be signed gives the participants the security to reach the intended recipient. In addition, transactions within the network are processed and confirmed in a few minutes without any detours.
Bitcoin’s Weaknesses
Bitcoin is subject to some restrictions that have deliberately set out in the protocol. The volume of transactions increases with the ever-increasing number of users. The high frequency means that nowadays, transactions can often no longer be processed quickly enough.
The origin of the problem lies in the block size determined by the protocol, the limit of which is simply insufficient for the current transaction density. The current block size was in 2010 to 1 MB fixed. This means that all blocks that exceed this size will rejected. The measure was initially intending to prevent hackers from crippling the system through attacks. Today, however, this decision is a limitation for the network and is increasingly causing users’ frustration.
So it is not uncommon for users to have to wait several hours for a transaction in times of heavy workload. Many Bitcoin developers and groups are currently working on solutions for the bitcoin scaling problems. One of the most determined and advanced projects is the so-called. Lightning Network
Decentralized Exchange
A decentralized exchange (DEX) is a digital asset exchange platform that works on the principle of decentralization, that is, without the involvement of a central authority. A decentralized exchange allows peer-to-peer trading of digital assets, that is, directly between investors . Therefore, users do not have to transfer their assets to the exchange, reducing the risk of possible theft or hacking of the exchange’s servers. Decentralization of operations also prevents possible price manipulation or fraudulent operations.
The Future Of Bitcoin
Bitcoin is open-source software, which means that the community constantly works on new technological developments, innovations, and features. Two of the most exciting and promising developments at the moment are the so-called “Schnorr signatures” and “MimbleWimble.”
Signatures
Every Bitcoin transaction that takes place within the network must be sign in. This signature enlarges the transaction data and thus harms the speed and inflates the size of the blockchain. With the help of Schnorr’s signature be, several transactions signed together. This will noticeably reduce the size of the trade and can help solve storage and scaling issues.
Mimble Wimble
“Mible Wimble” is a protocol that focuses in particular on scalability and anonymity. The basis of the protocol is again the blockchain. All transactions are cryptographically conceal so that they can no longer assign. Thanks to mathematical algorithms, however, it is still ensuring that no false coins can generated. In addition, it is not possible to send more money than is available in the account (“double spending”). The system’s lean architecture reduces the transaction data size, which greatly reduces the scaling problem. And also, The approach is currently in its infancy, which means that Mimble Wimble is currently only being use and testing in a few projects.
