Fees in the Blockchain. Our wallet uses dynamic fees , meaning that the wallet will calculate the appropriate fee for your transaction taking into account current network conditions and transaction size.
You can choose between a Priority fee and a Regular fee. The Priority fee is calculated to get your transaction included in a block within the hour. The Regular fee is lower, and is for users who can afford to be a bit more patient; a confirmation for a transaction that includes a Regular fee will typically take a bit more than an hour. Please note that setting too low a fee may cause your transaction to remain unconfirmed for a long time and possibly be rejected. Customize your transaction fee at your own risk. If you want to take a deeper dive into bitcoin transaction fees, this blog post provides a comprehensive overview of what fees are and how they work, and this one elaborates on some frequently asked questions.
If you have an unconfirmed transaction, you can learn more about what this means here. Blockchain Support Center Cryptocurrency FAQs Bitcoin FAQ Every bitcoin transaction must be added to the blockchain, the official public ledger of all bitcoin transactions, in order to be considered successfully completed or valid. Network conditions Because a block on the bitcoin blockchain can only contain up to 1 MB of information, there is a limited number of transactions that can be included in any given block.
On top of SegWit, bech32 addresses add even more improvements and decrease fees a little more as well. Some services have adopted SegWit transactions but not bech32, a format specifically made for SegWit transactions.

SegWit, bech32 — all these different changes are confusing. Note: These lists might not be fully up to date. Some more recent SegWit adopters, such as BitPay , have not made these lists yet. That said, SegWit is not necessarily the default type of transaction in wallets that support it. Users will need to make sure to specifically select the SegWit option when creating their wallet to make sure they can send bitcoin transactions with lower fees.

CoinDesk is an independent operating subsidiary of Digital Currency Group , which invests in cryptocurrencies and blockchain startups. Thomas Meyer Mar 29, The cash stock market is the most popular and active capital market in the world. The rise of stocks is directly influenced by national policies. The stock market is also the engine and booster of national economic development.
According to statistics, nowadays, it is an era of the national stock speculation. At present, China has more than million investors in the stock market, and people pay more attention to the stock industry. However, due to the process of traditional asset management, such as equity and securities that take a long time, there is an increase in the intermediate business cost, transaction fee, information fraud, disclosure, etc. Moreover, it is managed by different intermediaries, which not only increases the transaction cost of assets, but also causes the problem of certificate falsification.
The emergence of the blockchain provides a solution for it, which can upgrade securities trading to the automatic execution of intelligent contracts. Since it allows payments to be finished without any bank or any intermediary, the blockchain can be used in various financial services such as digital assets, remittance, and online payment [ 1 ].
Through P2P trading transmission, it not only saves the intermediate process and reduces the cost and loss, but also guarantees the private security of trading information and changes the trading efficiency of the stock market. In addition, the Markov chain can select a decision-making from the available set of actions based on the observed state at each moment. At the same time, the system can make new decisions based on the observed newcome states.

Markov chain can be used to conduct the dynamic optimization of the resource scheduling scheme in the stock trading process, and the optimal resource scheduling scheme can be found to ensure the timeliness of the transaction. In , Satoshi Nakamoto proposed an electronic cash system for bitcoin, which could be implemented through peer-to-peer P2P technology, allowing online payments to be initiated directly by one party to another without going through any financial institution [ 2 ]. As the underlying key technology and infrastructure of bitcoin, the blockchain has attracted great attention from academia and industries.
A blockchain, originally blockchain [ 4 ], is a growing list of records, called blocks, which are linked and secured by using cryptography [ 5 ].
Each block contains a cryptographic hash of the previous block [ 6 ], a timestamp, and transaction data. A blockchain is a decentralized, distributed, and public digital ledger that is used to record transactions across many computers so that any involved record cannot be altered retroactively, without the alteration of all subsequent blocks [ 7 ]. Blockchain technology has the key characteristics, such as decentralization, persistence, anonymity, and audibility. Blockchain can work in a decentralized environment and be realized by multiple core technologies such as the integrated password hash, the digital signature based on asymmetric encryption , and the distributed consensus mechanism.
Based on a distributed P2P network, blockchain technology combines consensus mechanism, smart contract, and privacy protection with the open source software to ensure the continuity and security of each node in the distributed database. These can make information instant verifiable and traceable, but it is difficult to change and revoke.
Thus, blockchain technology is a set of private, efficient, safe, and shared value systems.
Blockchain can serve not only to save the operating costs of the companies, but also to retrench the potential legal fees arose from disputes which could have been avoided [ 8 ]. In December , Vitalik proposed Ethereum, a blockchain platform, which could realize digital currency transactions based on ether currency. Simultaneously, this platform can also provide a complete programming language to write a smart contract [ 9 ].
It is the first time that an intelligent contract is applied to the blockchain. Because the blockchain allows payments to be completed without any bank or agency, it could be used in various financial services [ 10 , 11 ]. Besides, blockchain technology is applied in other scenarios, such as smart contracts [ 12 ], public services [ 13 ], Internet of Things IoT [ 14 ], reputation systems [ 15 ], and security services [ 16 ].

However, further work still needs to explore the full capabilities of the blockchain and where it can be adopted. Markov chain was proposed by Andrey A. Markov, a Russian mathematician. It refers to the random transitioning process from one state space to another state space. This process requires memory-less properties. The probability distribution of the next state can only be determined by the current state, which has nothing to do with the original state or the Markov process before the transition.
The probability function of a Markov chain is a random process generated by two interrelated mechanisms. One is a potential Markov chain with a finite number of states, and the other is a set of random functions. At discrete instants of time, the process is assumed to be in some state, and observation is generated by the random function corresponding to the current state [ 17 ]. Markov chain is a powerful mathematical tool that is widely used to capture random transitions between different states of a system. Since the complexity of the model can be greatly reduced by utilizing the properties of the Markov chain, it has been widely used in many time model sequences and became one of the most widely applied algorithms.
Cerqueti et al. And, Li et al. Markov chain has been widely used for prediction in other fields, such as parallel computing [ 20 ], data modeling [ 21 ], information freshness [ 22 ], robotic surveillance [ 23 ], and transformer health estimation [ 24 ].

In the model construction, Ma et al. Li et al. However, the existing research studies did not fully consider the resource utilization in the queuing process. In order to solve the above problem, we propose a blockchain-enabled queuing model based on service priority. To the best of our knowledge, this paper proposes creatively a set of theoretical methods and prototyping based on the blockchain tactics and the Markov chain model and attempts to apply it in the stock trading.
By doing a lot of market investigation and reading plentiful references, aiming at some deficiencies of existing methods, we proposed a multipriority prediction model in the blockchain based on the Markov chain and queuing theory. Compared with the previous approaches, our proposed method and model has the following advantages: i Combining queuing theory with the blockchain: this paper creatively proposes a queuing model of multipriority service object preemption based on the blockchain scenario.

The different priority service objects in the scenario are also discussed. In the following sections, we will analyze and summarize the principle and basic knowledge of the Markov chain and the queuing theory. Through the analysis of the Markov chain and the blockchain, it is not difficult to find that they belong to the chain structure. Therefore, by combining the queuing model with blockchain technology, this paper proposes a new stock trading method based on the blockchain.
Section 2 mainly presents the work related to the blockchain, Markov chain, and queuing theory. Section 3 introduces the theoretical knowledge of the Markov chain and queuing theory. Section 4 establishes a queuing model with priority based on the blockchain. Section 5 uses the Markov chain to schedule resources for the queuing model. Section 7 concludes this paper. The method proposed in this paper optimizes and improves the stock trading, which can shorten the settlement time and improve the liquidity of funds. The development of the blockchain is been explored, and its application scenarios have been expanded from a single electronic virtual currency trading system to the other wider fields.
Today some of the largest financial institutions in the world, including central banks, major commercial banks, and stock exchanges, have launched ambitious projects to use the blockchain in both wholesale and retail applications [ 27 ]. They were committed to applying blockchain technology to real-world production environments and realizing the ultimate goals of high efficiency and low consumption.

The security of the blockchain has always been one of the hotspots, and many researchers have made a host of contributions to this problem [ 28 — 30 ]. In other applications, in , Li et al. Their work also provided an optimal pricing strategy for the Stackelberg game based on credit loans [ 31 ]. Due to the lack of some comprehensive literature reviews on the development of decentralized consensus mechanisms in the blockchain network, in , Wang et al. In the same year, Hussein et al.
In , Andoni et al. Then, they introduced the current development prospects of the blockchain into industrial projects and entrepreneurial firms in brief. Finally, they discussed the challenges and market obstacles that blockchain technology needs to conquer and proved its commercial feasibility [ 34 ].
