㈠什么是比特币的扩容为什么要扩容

每个区块大小是一兆，大概能容纳一千多条交易的信息，如果你上一个比特币区块链浏览器上去观看的话，你会查到现在每一个区块大概都是一兆左右，已经达到了区块容量的上限，如果比特币的网络的转账越来越多，很多交易就不会在交易发生后第一个发生的区块被打包和确认。可能要等好几个区块或者时间更长，在比特币的历史上曾经遭遇过几次粉尘攻击，其中就有很多交易者在交易所（币汇）制造大量的小额转账，粉尘攻击就是有人制造出大量的小额转账，使得网络中有大量的待确认的交易，导致正常的转账不能够被确认，确认时间被延迟，影响网络的正常运转。
很多交易者的交易等待两天或者是更久才得到确认，虽然粉尘攻击是非常极端的例子，但是看现在的比特币的网络，正常的转账量，已经远远超出了他能够承受的最大的容量，每个区块大小现在都是一兆，所以扩大比特币区块容量，突破现有一兆大小的限制，这个过程叫做扩容。

㈡什么是比特币合约

类似期货合约，是由bitstar提出的一种交易方式。
比特币虚拟合约的杠杆表现为法币收益层面的杠杆稳定：投入100美元，所能得到的收益=100美元*比特币的涨跌幅*固定的杠杆倍数。
假设当前价格为500usd/btc，某投资者以当前价格买入一个btc，本金为500usd,此时投资者可以做多50张btc虚拟合约。此时若btc价格上涨至750美元，涨幅50%，投资者合约收益为3.3333个btc，按照当前价格卖出后可以获得2500美元，收益为其本金投入的5倍。若价格上涨至1000美元，合约收益为5btc，卖出后的美元收入为5000美元，为其美元收入的10倍。无论价格怎么波动，合约的杠杆都十分稳定，从而方便商家用合约进行套保，也便于普通投资者管理其仓位。

㈢闪电网络的崛起真的决定比特币的未来吗

比特币诞生至今已经十年了。十年前，如果有人告诉他的创始人中本聪，这种新的去中心化货币在2019年将会蓬勃发展，那么他可能会认为自己的实验成功了。比特币确实是有可能成为世界货币的，即使它并不像中本聪说的那样神奇，甚至在10年后的今天，依然还有人对其白皮书中的设想进行抨击。

虽然现在比特币已成为一种广泛使用的投资和投机资产，但由于其自身的设计和庞大的需求量，导致比特币离它完全去中心化自由货币的目标还很远。但如果新的解决方案确实解决了一些现有的问题，那么它的现状肯定会得到很大的改善。只要比特币区块链的交易成本不高于闪电网络，那么用户就不会把资产转移到其他公链上。比特币区块链未来如果还能通过除闪电网络之外的其他解决方案去不断扩大交易处理量，那么它最终就可能发展成为中本聪最初设想的世界货币。

㈣比特币合约是什么意思

比特币合约，是指无需实际拥有比特币也可进行交易的合约。它与必须实际持有数字货币才可进行的币币交易有很大不同。

比特币合约使你能够预测比特币的价格走势和对冲风险。这种交易方式，意味着你投资的是价格趋势，而非资产本身。

在交易比特币合约时，你可以决定做空还是做多。选择做多，表明你预计比特币价格将会上涨。另一方面，选择做空表明你预计价格将会下跌。

杠杆交易

可以选择高杠杆率进行交易，是比特币合约的一项特性。使用杠杆, 意味着你在进行合约交易时,不必投入100％的交易金额。相反，你只需要存入初始保证金，而保证金额度仅占合约总价值的一小部分。

杠杆交易让你在风险管理的同时，用少量的资金占有较大敞口。

永续合约

虽然合约有许多不同类型，本文主要关注永续合约。顾名思义，这些合约没有到期日。使用永续合约做多或做空的交易者，可以无限期持有头寸，除非合约爆仓，这意味着他们遭受的亏损不会超过初始保证金。

永续合约中，比特币的定价以特定的指数价格为基础。指数价格基于多个币币交易市场上比特币的平均价格。

比特币合约已成为一种非常流行的交易工具。许多传统投资者尚未准备将资金分配到数字资产上，但仍希望从诱人的价格波动中受益，而合约交易为他们打开了大门。

如要开启比特币合约交易，需要找到提供合约交易的交易所。 AAX平台，在合规和安全的环境中，为你提供比特币合约交易服务。

㈤闪电比特币和闪电网络是同一个东西

老实说我一开始也跟题主遇到一样问题，看到新闻有点疑惑就去搜了下，结果不管是搜索闪电比特币还是Lightning bitcoin的时候，不是出来闪电网络就是出来比特币......这名字还蛮有毒的。

言归正传吧，先说结论，完全不是一个东西。

很多人讲过闪电网络是什么了，可以看看其他人的答案来去深入了解他的机制，或是英文好点的上官网直接看他们出的论文http://lightning.network/。闪电比特币官网有中文的，省了翻译的麻烦https://lbtc.io/。两个闪电的起源很相近，都是希望解决比特币网络拥堵问题，只是一个是用搭载协议的方式，另一个是用分叉改共识的方式，两者的成果也都不错，在交易速度方面提升很大，都可以算是实时性的。下面直接以表格来表示两者的异同：

以上可以看出来，两者差异还是比较大的，应该不会再弄混了吧~

㈥什么是比特币的闪电网络

2015 年 2 月，比特币开发者Joseph Poon和Thaddeus Dryja在论文《The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments》中提出了可扩容的链下支付---闪电网络的概念。我们知道，比特币网络之所以可靠，一个很重要的原因是因为所有的比特币节点都保存了比特币账本，如果有人想篡改交易记录，就要全网一半以上的算力。没有了区块链网络这个信任的机器，怎么保证交易的双方不会反悔、抵赖？闪电网络到底是怎么实现的？

简单来说，闪电网络是基于比特币扩容问题，由于比特币区块受限，那就要求搭建一个新的通道，小额交付的过程可以通过闪电网络的通道而不需要比特币矿工记账，既能加快速度，又能降低手续费，但这样的闪电网络怎么防止中心化问题？更多详细内容这个视频讲的很详细：六分钟搞懂闪电网络

但是到底闪电网络能多久落地还是个疑惑？

㈦ lock contract在区块链里是什么意思

意思是锁定合约。
锁定合约包含哈希锁定（Hashlock）以及时间锁定（Timelock）两个部分，哈希时间锁定合约最典型的代表就是比特币的闪电网络，闪电网络提供一个可扩展的微支付通道，用以提升链外的交易处理能力，使用哈希锁定将发起方的交易代币进行锁定，并通过时间锁定让接收方在某个约定的时刻前生成支付的密码学证明，并与先前约定的哈希值一致，则可完成交易。

㈧比特币合约交易什么意思

合约交易是对比特币莱特币期货合约交易的统称。
2013年6月，796交易所在比特币业内率先开发出了比特币周交割标准期货—T+0双向交易虚拟商品作押易货合约（合约交易）。
合约交易的出现结束了此前比特币不能做空的历史，开启了比特币衍生品市场发展繁荣的序幕。

㈨什么是比特币期货合约

比特币期货合约，通常是以比特币价格指数为标的的标准化合约。

比特币交易所提供的比特币期货通常是以比特币进行交易的。期货是与现货相对的，现货是实实在在可以一手交钱一手交货的商品，而期货其实不是“货”，是承诺未来一个时间交“货”（标的）的约定（合约）—期货合约。

标的：又叫基础资产（underlying asset），解释了买卖什么东西的问题。目前比特币期货标的都是比特币价格指数，并且结算和交割价格的产生方法都以这个指数为基础。

手续费：与股票交易需缴纳印花税、佣金、过户费及其他费用不同，期货交易的费用只有手续费。比特币期货交易手续费有开仓收费和平仓收费两种，即在建立仓位时收取（如OKCoin）和在平仓时收取（如796）。比特币期货手续费一般是合约总价值的0.03%。

保证金：保证金跟另一个概念息息相关—杠杆，一般以杠杆比例来反映收益和风险水平。如796新推的50倍杠杆（即2%保证金），它意味着投资者投入1个比特币就可以购买50个比特币的期货合约（即50倍杠杆）；

或者从另一个角度看，投资者投入的1个比特币相当于购买到的50个比特币的2%（即2%保证金比例）。

通过50倍杠杆，期货相对于现货的收益被放大了50倍，比如同时购买1个币的现货和用1个币买多50个币的期货，假定现货和期货价格都上涨100%，那么现货赚了1个币，而期货则赚了50个币。

(9)比特币合约中的时间锁扩展阅读

期货合约是买方同意在一段指定时间之后按特定价格接收某种资产，卖方同意在一段指定时间之后按特定价格交付某种资产的协议。双方同意将来交易时使用的价格称为期货价格。

双方将来必须进行交易的指定日期称为结算日或交割日。双方同意交换的资产称为“标的”。如果投资者通过买入期货合约（即同意在将来日期买入）在市场上取得一个头寸，称多头头寸或在期货上做多。

相反，如果投资者取得的头寸是卖出期货合约（即承担将来卖出的合约责任），称空头头寸或在期货上做空。

㈩比特币合约怎么玩

正常的合约交易所是，假设你账户中的保证金是10万元，你开了5倍杠杆，买入了看多的比特币合约，这时候，你的保证金会被放大5倍，收益和风险也同时扩大了5倍。
如果比特币上涨10%，那么你就赚了10万*10%*5=5万元。
如果比特币下跌了10%，你就亏损了5万元，等到比特币下跌20%，那么你的保证金就全部亏损，也就是你爆仓了。
至于怎么赚钱
这个就要看你的运气，以及自身的交易经验和交易技术了。

㈠ What is the expansion of Bitcoin and why it needs to be expanded?

The size of each block is one megabyte, which can accommodate more than a thousand transaction information. If you go to the Bitcoin area If you go to the blockchain browser and watch it, you will find that each block is about one trillion now, which has reached the upper limit of the block capacity. If there are more and more transfers on the Bitcoin network, many transactions will not The first block that occurs after a transaction occurs is packaged and confirmed. It may take several blocks or longer. Bitcoin has encountered several dust attacks in its history. Among them, many traders created a large number of small transfers on exchanges (Bihui). Dust attacks are caused by someone. A large number of small-amount transfers are created, resulting in a large number of transactions to be confirmed in the network, causing normal transfers to not be confirmed and the confirmation time to be delayed, affecting the normal operation of the network.
Many traders wait two days or more for their transactions to be confirmed. Although the dust attack is a very extreme example, looking at the current Bitcoin network, the normal transfer volume has far exceeded what he can The maximum capacity that can be tolerated, each block size is now one trillion, so expanding the Bitcoin block capacity and breaking through the existing one trillion size limit is called expansion.

㈡ What is a Bitcoin contract?

Similar to a futures contract, it is a trading method proposed by bitstar.
The leverage of the Bitcoin virtual contract is the stability of the leverage at the level of legal currency income: if you invest $100, the income you can get = $100 * the rise and fall of Bitcoin * fixed leverage multiple.
Suppose the current price is 500 usd/btc, and an investor buys a btc at the current price with a principal of 500 usd. At this time, the investor can go long 50 btc virtual contracts. At this time, if the price of Bitcoin rises to US$750, an increase of 50%, the investor's contract income will be 3.3333 Bitcoins. After selling at the current price, he can get US$2,500, and the income will be 5 times of his principal investment. If the price rises to US$1,000, the contract income will be 5btc, and the US dollar income after selling will be US$5,000, which is 10 times its US dollar income. No matter how the price fluctuates, the leverage of the contract is very stable, making it convenient for merchants to use contracts for hedging and for ordinary investors to manage their positions.

Does the rise of the Lightning Network really determine the future of Bitcoin?

It has been ten years since the birth of Bitcoin. Ten years ago, if someone had told his founder Satoshi Nakamoto that this new decentralized currency would boom in 2019, he might have considered his experiment a success. It is indeed possible for Bitcoin to become the world's currency, even if it is not as magical as Satoshi Nakamoto said. Even today, 10 years later, there are still people who criticize the ideas in its white paper.

Although Bitcoin has now become a widely used investment and speculative asset, due to its own design and huge demand, causing Bitcoin to be far from its goal of a fully decentralized free currency. But if the new solution does solve some existing problems, then its status quo will definitely be greatly improved. As long as the transaction cost of the Bitcoin blockchain is not higher than that of the Lightning Network, users will not transfer assets to other public chains. If the Bitcoin blockchain can continue to expand transaction processing through other solutions besides the Lightning Network in the future, then it may eventually develop into the world currency originally envisioned by Satoshi Nakamoto.

㈣ What does Bitcoin contract mean?

Bitcoin contract refers to a contract that can be traded without actually owning Bitcoin. It is very different from currency-to-crypto trading, which requires physical possession of the digital currency to proceed.

Bitcoin contracts enable you to predict Bitcoin price movements and hedge risks. This type of trading means that you are investing in price trends rather than the asset itself.

When trading Bitcoin contracts, you can decide to go short or long. Choosing to go long indicates that you expect the price of Bitcoin to rise. On the other hand, choosing to go short indicates that you expect the price to fall.

Leverage trading

The ability to trade with high leverage is a feature of Bitcoin contracts. Using leverage means that you do not have to invest 100% of the transaction amount when trading a contract. Instead, you only need to deposit an initial margin, which is only a small percentage of the total contract value.

Leverage trading allows you to use a small amount of capital to occupy a larger exposure while managing risk.

Perpetual Contracts

Although there are many different types of contracts, this article focuses on perpetual contracts. As the name suggests, these contracts have no expiration date. Traders who use perpetual contracts to go long or short can hold their positions indefinitely unless the contract is liquidated, which means they will not suffer losses exceeding their initial margin.

In perpetual contracts, Bitcoin is priced based on a specific index price. The index price is based on the average price of Bitcoin on multiple cryptocurrency exchange markets.

Bitcoin contracts have become a very popular trading tool. Many traditional investors are not yet ready to allocate funds to digital assets but still want to benefit from attractive price movements, and contract trading opens the door for them.

If you want to start Bitcoin contract trading, you need to find an exchange that provides contract trading. The AAX platform provides you with Bitcoin contract trading services in a compliant and secure environment.

㈤ Lightning Bitcoin and Lightning Network are the same thing

To be honest, I encountered the same problem as the questioner at the beginning. I was a little confused when I saw the news, so I searched it. As a result, when searching for Lightning Bitcoin or Lightning Bitcoin, either Lightning Network or Bitcoin comes out... This name is quite poisonous.

Let’s get back to the point, let’s talk about the conclusion first, it’s not the same thing at all.

Many people have talked about what Lightning Network is. You can read other people’s answers to learn more about its mechanism, or if you are good at English, go to the official website and read their papers directly http:// lightning.network/. The official website of Lightning Bitcoin is in Chinese, which saves you the trouble of translation https://lbtc.io/. The origins of the two Lightnings are very similar. They both hope to solve the congestion problem of the Bitcoin network, but one uses a protocol-based method, and the other uses a fork to change the consensus. The results of both are good, in terms of transaction speed. The improvement is huge and can be considered real-time. The following is a direct table to express the similarities and differences between the two:

As can be seen from the above, the difference between the two is quite large, so there should be no confusion~

㈥ What is Bitcoin’s Lightning Network

In February 2015, Bitcoin developers Joseph Poon and Thaddeus Dryja proposed in the paper "The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments" Introduced the concept of scalable off-chain payment-Lightning Network. We know that a very important reason why the Bitcoin network is reliable is because all Bitcoin nodes save Bitcoin ledgers. If someone wants to tamper with transaction records, more than half of the computing power of the entire network will be needed. Without the trust machine of the blockchain network, how can we ensure that both parties to the transaction will not regret or deny it? How is the Lightning Network implemented?

To put it simply, the Lightning Network is based on the Bitcoin expansion problem. Since Bitcoin blocks are limited, a new channel is required to be built. The process of small-amount delivery can go through the Lightning Network channel instead of Bitcoin miners are required to keep accounts, which can speed up the process and reduce handling fees. But how can such a lightning network prevent centralization problems? More details: This video is very detailed: Understand the Lightning Network in six minutes

But how long it will take for the Lightning Network to be implemented is still a mystery?

㈦ What does lock contract mean in the blockchain?

It means locking the contract.
The locking contract consists of two parts: hash lock (Hashlock) and time lock (Timelock). The most typical representative of the hash time lock contract is Bitcoin’s Lightning Network. The Lightning Network provides a scalable micropayment channel. In order to improve the transaction processing capacity outside the chain, the hash lock is used to lock the transaction token of the initiator, and the time lock is used to allow the recipient to generate a cryptographic proof of payment before a certain agreed time, and match it with the previously agreed hash. If the expected values are consistent, the transaction can be completed.

㈧What does Bitcoin contract trading mean?

Contract trading is the collective name for Bitcoin Litecoin futures contract trading.
June 2013, 796 Exchange took the lead in the Bitcoin industry to develop Bitcoin weekly delivery standard futures-T+0 two-way trading virtual commodity pledged barter contract (contract transaction).
The emergence of contract trading ended the previous history that Bitcoin could not be shorted, and opened the prelude to the development and prosperity of the Bitcoin derivatives market.

㈨ What is Bitcoin Futures Contract

Bitcoin futures contracts are usually standardized contracts based on the Bitcoin price index.

Bitcoin futures offered by Bitcoin exchanges are usually traded in Bitcoin. Futures are opposite to spot goods. Spot goods are real commodities that can be paid and delivered in one hand. Futures are not actually "goods". They are an agreement (contract) that promises to deliver "goods" (subject matter) at a time in the future - a futures contract. .

Object: Also called underlying asset, it explains the question of what to buy and sell. Currently, the underlying targets of Bitcoin futures are the Bitcoin price index, and the settlement and delivery price generation methods are based on this index.

Handling fees: Unlike stock transactions that require stamp duties, commissions, transfer fees and other fees, futures trading only charges handling fees. Bitcoin futures trading fees include opening fees and closing fees, which are charged when a position is established (such as OKCoin) and charged when a position is closed (such as 796). Bitcoin futures handling fees are generally 0.03% of the total contract value.

Margin: Margin is closely related to another concept - leverage, which generally reflects the level of return and risk in terms of leverage ratio. For example, 796’s newly launched 50 times leverage (i.e. 2% margin) means that investors can purchase 50 Bitcoin futures contracts (i.e. 50 times leverage) by investing 1 Bitcoin;

or From another perspective, 1 Bitcoin invested by an investor is equivalent to 2% of the 50 Bitcoins purchased (i.e. 2% margin ratio).

Through 50 times leverage, the income of futures relative to spot is magnified 50 times. For example, if you buy 1 coin of spot and use 1 coin to buy 50 coins of futures at the same time, assuming that the spot and futures prices If both prices rise by 100%, then the spot price will earn 1 coin, while the futures price will earn 50 coins.

(9) Extended reading of time locks in Bitcoin contracts

A futures contract is an agreement between the buyer and seller for a period of timeAn agreement in which a seller agrees to deliver an asset at a specified price after a specified period of time. The price that both parties agree to use for future transactions is called the futures price.

The specified date on which both parties must conduct transactions in the future is called the settlement date or delivery date. The asset that both parties agree to exchange is called the “subject.” When an investor takes a position in the market by purchasing a futures contract (i.e. agreeing to buy at a future date), it is called a long position or going long on futures.

On the contrary, if the position taken by the investor is to sell a futures contract (that is, to bear the contract responsibility to sell in the future), it is called a short position or shorting on futures.

㈩ How to play Bitcoin contracts

The normal contract exchange is, assuming the margin in your account is 100,000 yuan, you open 5 times leverage, buy to see long Bitcoin contract, at this time, your margin will be enlarged 5 times, and the income and risk will also be increased 5 times.
If Bitcoin rises by 10%, then you will earn 100,000*10%*5=50,000 yuan.
If Bitcoin falls by 10%, you will lose 50,000 yuan. When Bitcoin falls by 20%, then all your margin will be lost, which means you will be liquidated.
As for how to make money
This depends on your luck, as well as your own trading experience and trading skills.
