Bitcoin transaction rate
Bitcoin's average transaction fees have never been higher. These high transaction fees coincide with a series of accidents at Chinese coal mines which have taken mining farms in the coal-rich regions of China offline.

Blockchain inefficiency in the Bitcoin peers network
In this paper, we model the emergence of the Lightning Network as a bond percolation process and we explore how the distributional properties of the volume and size of transactions per user may impact its feasibility. The emergence of a connected component is studied numerically and analytically as a function of the parameters, and the phase transition separating regions in the phase space where the Lightning Network is sustainable or not is elucidated.
We characterize the phase diagram determining the minimal volume of transactions that would make the Lightning Network sustainable for a given level of fees or, alternatively, the maximal cost the Lightning ecosystem may impose for a given average volume of transactions. The model includes parameters that could be in principle estimated from publicly available data once the evolution of the Lighting Network will have reached a stationary operable state, and is fairly robust against different choices of the distributions of parameters and fitness kernels.
Bitcoin, the pioneering cryptocurrency, has brought about an unprecedented revolution in the payment industry 1. Despite its traction and success over the last ten years, the original blockchain — the technological infrastructure underlying Bitcoin — suffers from some limitations that may hinder the future growth and adoption of the cryptocurrency. One of the major issues is the scalability of the system: the current number of transactions validated via this platform is between 3 and 7 transactions per second, compared for instance to thousands of transactions handled by the Visa circuit 2.
The lack of scalability is mainly caused by constraints on throughput of transactions, with the block size fixed at 1MB, and by the high latency — with a new block created on average only every ten minutes. Those limitations are imposed to safeguard the security of the platform against malicious attacks and are difficult to relax without major changes in the protocol.
The main solutions proposed to address the scalability issue include i changes to the main protocol consensus algorithm, parameters and ii sidechains and second-layer solutions see 3 for a recent technical review. Notable examples of type- i solutions include new consensus protocols, which would allow a faster issuance of new blocks among other new features 4. At the same time, sidechains are completely separate ecosystems whose technical features or issues would not be shared with the main blockchain.
By off-chain we mean that not all transactions are settled and stored on the main blockchain. In a nutshell, the idea of a Lightning channel is the following: two parties lock the same amount of money as collateral and open a channel for a certain period of time. During this time, they can then exchange money back and forth through the channel, and only the netted transaction will be eventually validated and stored on the main blockchain.
If one party is malicious and does not correctly update the balance, the other can keep the collateral posted by the malicious party, as a form of insurance. The scalability problem could be solved if a sufficient number of channels were opened, implying that the Lightning Network spans across the whole pool of users of the main blockchain.
The Lightning Network topology is, indeed, relevant to understand the resilience of the system to attacks or random failures and its robustness.
Experiments on random or targeted nodes removal from the network give information on the system resilience by monitoring when the original network is broken into multiple isolated clusters 8 , 9 , In a recent work on simple network topologies i. Indeed, transacting on the Lightning Network might impact the security of the main blockchain network by inducing a decrease in the amount of fees collected by the miners for the validation of blockchain transactions.
Fees on the main blockchain are used as incentives to miners i. In 16 the authors use a game-theoretic model to investigate the factors influencing the value of Bitcoin fees, while in 17 they also examine the interplay between fees and security of the platform, theoretically showing that the current fee model may not be sustainable in the long run. Alternative fee mechanisms have also been proposed, for instance based on auction models 16 , and compared with the existing one to highlight weaknesses and possible improvements.
The Bitcoin ecosystem has been already extensively investigated using approaches based on complex networks. The transactions network has been studied to understand latency issues and propagation mechanisms in peer-to-peer systems 18 and inefficiencies of the process of permanent inclusion of the transactions on the blockchain More generally, our paper taps into the growing literature on quantitative investigations of the cryptocurrencies landscape, including models of pricing and adoption of tokens 24 , 25 , 26 , 27 , analysis of the market structure 28 , 29 , 30 , 31 , 32 , 33 , 34 , price prediction based on sentiment and social interactions 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , dynamical analysis of informational efficiency 44 , and centralization of the Bitcoin economy In this paper, we investigate under which conditions in terms of blockchain and Lightning fees, average wealth and volume of transactions per user, a Lightning Network that spans a sizeable fraction of Bitcoin users — thus solving the scalability problem — emerges.
We model the emergence of the Lightning Network as a bond percolation process on a graph, exploring how different conditions may impact its feasibility In particular, we consider fitness-dependent network models 47 , 48 , 49 , 50 where the probability of creating a new edge depends on intrinsic node features collectively denoted node fitness. In the LN case, the node fitness will be defined in terms of the node wealth and activity i. The viability of the Lightning Network will be characterized in terms of the presence or not of a giant connected cluster of nodes: a non-fragmented network would, indeed, guarantee a smooth relay of payments and information between users and will incentivize off-chain transactions.
Our model depends on parameters that can be all obtained — or at least estimated — from publicly available data, and is fairly robust against different choices of distributions of parameters and fitness kernels. The paper is organized as follows. In the following section we provide a quick overview of the main Bitcoin blockchain and the main ideas behind LN. The Appendices are devoted to technical aspects of percolation theory on networks and are included to make the paper self-contained.
In this section, we summarize the main features of the Bitcoin main blockchain and Lightning Network payment layer. The Bitcoin blockchain is a distributed, shared ledger that immutably records transactions among peers in the network 1 , Transactions are bundled in blocks and chained together via cryptographic primitives to ensure that any change at any point in the transaction history would invalidate the full record.
The idea behind the creation of the Lightning Network 6 is, therefore, to devise a network for frequent and fast micro-transactions that can be performed at low transactions fees.
The basic components of the Lightning Network are payment channels schematically shown in Fig. In the typical payment channel implementation, a theoretically unlimited amount of payments can be made, with only two transactions broadcast on the blockchain.
In addition to a reduction of the number of blockchain transactions and associated costs, payment channels also offer the advantage of speed and, importantly, the ability of users to recover their funds if one of the parties is malicious. Panel A : Scheme of a payment channel between party A and B, including opening and closing transactions settled on the main blockchain, and intermediate transfers handled off-chain on the Lightning Network. Only when the two parties agree that the channel is no longer needed, they settle the net balance of funds on their original Bitcoin addresses.
Panel B : Scheme of payments routing on a Lightning Network: even if party 1 and 4 are not directly connected via an existing LN channel, they can route their payments through other parties upon payment of a fee by choosing a suitable cryptographic lock for the Bitcoins.
A channel is established between two parties by locking an initial amount of funds, for instance m Bitcoins for each user, on the main blockchain, which represents the maximum amount of Bitcoins that can be transferred over the channel. Funds are locked on so-called 2-of-2 multisignature addresses 14 , which can be unlocked upon providing the signature of both interested parties. For instance, user A wishes to send r Bitcoins to user B: she signs a transaction, sends it to B, who will sign it and send it back to A.
Only the first transaction is recorded on the main blockchain. At each time step in the lifetime of the channels, the users keep sending back and forth signed transactions that can be at any point consensually broadcast on the main blockchain to close the channel and redeem the net amount of funds.
To prevent fraudulent behavior, for instance user B not acknowledging the receipt of a payment from A, a refund option is always included in any exchange.
Every new refund option is indeed signed by both parties, signaling therefore that they are in agreement with the terms of the refund, which may be exercised unilaterally at a later time. In the worst-case scenario, one party would simply submit the original refund transaction created contextually with the opening of the channel.
Payments can be relayed via the Lightning Network also if two parties are not directly connected via a Lightning channel, if there exists a path indirectly linking them via existing channels owned by third parties. Exploiting an existing path to route the payments may often prove more convenient as the two interested parties need not open a new channel, therefore saving the associated costs in blockchain fees.
In Fig. One of the biggest issues of the Lightning Network is the limitation in liquidity. To prevent dishonest behavior in the transfer from party 1 to 4 via party 2 and 3 see Fig. In this section, we model the emergence of the Lightning Network as a bond percolation process.
We will consider two explicit examples for the wealth distribution uniform and exponential in the following, with qualitatively similar results. Two nodes are more likely to open a Lightning channel if they expect to submit a large number of transactions over a given period of time. We also include the costs associated with transacting over one of the two networks main blockchain only or blockchain and Lightning.
These costs can be fixed per transaction base fee or can be calculated as a percentage of the value transferred fee rate. Opening a channel has also maintenance costs fee setup, market and nodes monitoring, connections and costs related to locking Bitcoins and providing liquidity in the channel. The growth of the Lightning Network can be modeled as a bond percolation process on a set of N nodes representing Bitcoin users.
The edges then represent new Lightning channels being opened. In particular, we construct the bond percolation model considering fitness-dependent networks 47 , 48 , 49 , The network we consider has a fixed number of nodes N — corresponding to all Bitcoin users that may decide to switch to the LN — and is sparse , i. If we consider node i and j having fitness x i and x j respectively, a LN channel, i. In the context of the LN network, we define the fitness x i of node i as the simplest increasing function of both capacity and volume of transactions, i.
If we imagine links are added one at a time at a given rate, from the kernel f x , y we can derive the probability that a node with fitness x increases its degree by one as The same considerations apply to its counterpart j.
It is therefore of paramount importance to understand under which conditions on the average wealth, average volume of transactions, and routing fees, this transition may happen, and what finite fraction of nodes will it involve. Schematic representation of the emergence of the connected component among fit nodes, below left and above right the percolation threshold. Hence, we have. Simplifying we obtain.
In this case, it follows from 6 and 9 that. Splitting the integration region, we get. Computing now the generating function The general theory see Appendix B, in particular Eq.
The average size of the giant component thus reads from Eq. The fitness distribution now becomes. As in the uniform-wealth case. Increasing the average wealth w 0 would push the curves upwards: as more liquidity becomes available across nodes, more and more players may get involved in the LN for the same level of routing fees.
Simulations with kernel f x , y in Eq. To find the size of the largest connected component, we use a breadth-first search algorithm 54 : starting from a source node s , we label it as belonging to cluster 1. We then explore its neighborhood and assign all nodes reachable from s to cluster 1 as well.
The algorithm proceeds recursively until either the whole network has been labelled, or no unlabelled nodes can be further reached. In the latter case, we select another random source among the unlabelled nodes, assign it the label 2, and restart the procedure to find another cluster.
At the end, all disjoint clusters have been identified, and their size recorded. In our plots, we monitor the size of the largest cluster.
The sharp transition between the two regimes i. As a matter of fact, different platforms are currently being offered — but only at a test stage — where users can experience the Lighting Network services in a simulated environment. The function f x , y in Eq.
Visualizing Dynamic Bitcoin Transaction Patterns
Blockchain promises to solve this problem. The technology behind bitcoin, blockchain is an open, distributed ledger that records transactions safely, permanently, and very efficiently. For instance, while the transfer of a share of stock can now take up to a week, with blockchain it could happen in seconds. Blockchain could slash the cost of transactions and eliminate intermediaries like lawyers and bankers, and that could transform the economy.
How Long Does a Bitcoin Transaction Take?
Bitcoin is a decentralised digital or virtual currency. An easy way to think of it is like cash for the internet. It was founded by Satoshi Nakamoto in and first went live in There is an air of mystery that surrounds Satoshi Nakamoto - much debate circulates in online forums as to who or whom Satoshi Nakamoto could be, and if he even exists. However, no one has publicly admitted to being the founder of Bitcoin. Bitcoins are traded on exchanges in the same way that securities are. Due to the very low transaction costs associated with Bitcoin, it appeals to foreign nationals transferring money home, or by those emigrating from countries where it is prohibited to leave with local currency e.

Cryptocurrencies such as Bitcoin are breakthrough financial technologies that promise to revolutionize the digital economy. Unfortunately, their long-term adoption in the business world is imperiled by a lack of stability that manifests as dramatic swings in transaction fees and severe participant dissatisfaction. To date, there has been little academic effort to study how system participants react to volatility in fee movements. Our study addresses this research gap by conceptualizing the Bitcoin platform as a data space market and studying how market equilibrium forms between users who demand data space while trying to avoid transaction delays, and miners who supply data space while trying to maximize fee revenues. Our empirical analysis based on past bitcoin transactions reveals the existence of a relatively flat downward-sloping demand curve and a much steeper upward-sloping supply curve.

Secure High-Rate Transaction Processing in Bitcoin
Cryptocurrency, sometimes called crypto-currency or crypto, is any form of currency that exists digitally or virtually and uses cryptography to secure transactions. Cryptocurrencies don't have a central issuing or regulating authority, instead using a decentralized system to record transactions and issue new units. Cryptocurrency is a digital payment system that doesn't rely on banks to verify transactions. Instead of being physical money carried around and exchanged in the real world, cryptocurrency payments exist purely as digital entries to an online database describing specific transactions.

Over the weekend, the Bitcoin hash rate dropped off a cliff, leaving many industry participants wondering what had happened. Over the last couple of days, information and context has been provided by industry experts as to what was behind this steep fall in hash rate. For instance, this Twitter thread by Mustafa Yilham does a great job explaining the current situation. TLDR: A large amount of Bitcoin miners in the Xinjiang region had to shut off their machines, due to a water leakage in a coal mining plant that led the central and local governments in China to temporarily shut down operations at other coal mining operations.
