具体实施方式
以下结合附图对本发明的实施例进行详细说明，应当理解的是，以下实施例仅是为了说明和解释本发明，并不对本发明进行限定。
如图1所示，在本发明一种实施例中，一种合约交易装置包括：
合约标的管理器，用于管理第一资产A和第二资产B之间的合约汇率Ph；
所述合约汇率Ph为买方和卖方对第一资产A兑基础资产的价格PhA和第二资产B兑基础资产的价格PhB之比，即Ph＝PhA/PhB。
保证金确定器，所述保证金确定器用于供交易用户从其可用资产中选取一种作为交易保证金；
这里交易用户的保证金不限于品种A和品种B，也可能是其他资产，如品种AB。
交易引擎，所述交易引擎用于收到交易用户对所述合约汇率Ph的交易指令后执行交易，例如，交易引擎收到做多和做空的交易用户交易指令后，执行做多和做空的交易用户之间的撮合交易；交易用户包括做多的买方或做空的卖方。
现货行情处理器，所述现货行情处理器被配置为可以向现货行情服务器网关发起查询请求以获取第一资产A和第二资产B的现货价格或第一资产A和第二资产B之间的现货汇率Px；可选的，现货汇率Px与合约汇率相等。
这里的现货行情服务器既可以是中心化的交易所，如币安、火币、OKEX等中心化交易所，也可以是去中心化交易所，如Uniswap、Curve、SushiSwap、Balancer、Kyber Network等，具体可以参考 https://debank.com/ranking/dex，当然现货行情服务器并不限于是交易所，还可以是提供报价的第三方报价平台，如tradingview、aicoin等，或者从基于区块链的预言机Link等获取现货价格信息。
所述现货汇率Px为第一资产A现货价格PxA和第二资产B现货价格PxB的比值，即Px＝PxA/PxB。一般的，在现货资产放大合约交易中，Px＝Ph，在期货资产放大合约交易中，Ph会偏离Px。本发明中的价格是指交易标的涉及的第一资产A和第二资产B的兑换数量之比。
用户持仓调整处理器，所述用户持仓调整处理器被配置为根据所述合约汇率Ph的变化，使得交易用户的合约持仓量在连续的一个时间段内折合第一资产A的数量与合约汇率Ph负相关，折合第二资产B的数量与合约汇率Ph正相关；
交易数据存储器，所述交易数据存储器包括用于存储交易用户的基本信息，所述基本信息包括下单信息、持仓情况、资产放大率、成交记录中至少之一；所述交易数据存储器还可以用于存储行情数据等；平仓处理器，所述平仓处理器用于对达到预设平仓价格的交易用户发起强制平仓指令；
这里的预设平仓价格指的是在用户开仓时设定的价格，而不是实时计算出来的价格。
在一个实施例中，所述发起平仓指令距离所述用户开仓时间大于或等于所述连续的一个时间段。
通过上述交易系统，交易用户可以仅仅在持有一种保证金资产的情况下，交易 多个品种的汇率变化，相当于同时持有了多种资产，通过持仓调整系统，使得交易用户根据合约汇率Ph的变化同时动态调整第一资产A和第二资产B的持仓量，可以很好的降低自动做市商多资产持有风险。
为了更好的适应市场变化情况，有效降低自动做市商上述风险，用户持仓调整处理器还可以被配置为根据所述合约汇率Ph的变化，使得交易用户的合约持仓量在连续的一个时间段内折合第一资产A的数量随着合约汇率Ph的下跌而增加，折合第二资产B的数量随着合约汇率Ph的上涨而增加；或者用户持仓调整处理器还可以被配置为根据所述合约汇率Ph的变化，使得交易用户的合约持仓量在连续的一个时间段内折合第一资产A的数量随着合约汇率Ph的上涨而减少，折合第二资产B的数量随着合约汇率Ph的下跌而减少；
这里需要说明的是，在连续的一个时间段内，指的是做多和做空的交易用户持仓量的上述关系具有可持续性，例如持仓时间大于自动做市商在区块链上一个区块的时间，即做多和做空的交易用户的合约持仓量在连续的一段时间内都应该满足上述关系。
为了更加精确的降低上述风险，用户持仓调整处理器被配置为根据所述合约汇率Ph的c次幂的变化，使得交易用户的合约持仓量在连续的一个时间段内保持为折合第一资产A的数量为b/(Ph)^c的d倍,其中0<c<1,b>0,d>0，b和c为预设常数；
可选的c＝0.5，d＝1,下面以Uniswap交易为例，详细说明一下本发明的合约交易装置是如何降低Uniswap无常损失风险或实现单一资产挖矿的，提高用户资产和数据的安全性，我们知道Uniswap是基于恒定乘积自动做市机制，即在一个资金池中包括第一资产A和第二资产B，
这里以第一资产A数字货币ETH和第二资产B数字货币USDT构成的资金池举例说明，但本发明不受具体品种的限制，其中资金池中数字货币ETH的数量为x，数字货币USDT的数量y,那么资金池数字货币ETH-数字货币USDT满足y＝k/x,则交易者实际的兑换价格P为|⊿y/⊿x|，那么|⊿y/⊿x|＝|dy/dx|＝|y’|＝k/x^2,即x＝(k/P)^0.5,
假定一个使用本发明合约交易装置的流动性挖矿用户希望长期持有数字货币ETH，同时又想在Uniswap进行流动性挖矿赚取手续费和代币，然而在相关技术中却找不到有效的手段，当数字货币ETH价格上涨时，做市商将损失数字货币ETH，价格下跌时将损失数字货币USDT，这就是所谓的无常损失，为了便于用户操作，一般将b/(Ph)^c的范围设置在等值0.1美元至1000美元之间，在一个实施例中，本发明合约交易装置中的参数设置为b＝1,c＝0.5,这里每个交易用户的b和c均相同，这样可以将每个交易用户的合约持仓量均分成多份合约，单份合约绝对价值维持在1/(Ph)^0.5个数字货币ETH，
由于1/(Ph)^0.5与价格呈负相关关系，为了与实际市场走势相同，我们将单份合约价值定义为-1/(Ph)^0.5个数字货币ETH，此时合约价值将随着价格上涨而增大，符合市场规律，这样也可以满足 交易用户的合约持仓量在连续的一个时间段内保持为折合第一资产A的数量为b/(Ph)^c的d倍的要求，在数字货币ETH/数字货币USDT价格为P0时做市商向Uniswap资金池数字货币ETH-数字货币USDT存入x0个数字货币ETH和y0个数字货币USDT，同时在本发明合约交易装置中做多L＝2x0*((P0)^0.5)份合约，即此时持有-2x0个数字货币ETH，当数字货币ETH/数字货币USDT价格波动到Pn时:
在Uniswap中不考虑手续费的情况下满足：
x0＝(k/P0)^0.5
xn＝(k/Pn)^0.5
Uniswap中数字货币ETH的盈亏变化为：2xn-2x0＝2*x0(P0/Pn)^0.5-2x0
流动性挖矿用户在本发明合约交易装置持有的数字货币ETH仓位将在用户持仓调整处理器的控制下，调整为：-2x0*((P0)^0.5)*1/(Pn)^0.5
流动性挖矿用户在本合约交易装置中数字货币ETH的盈亏变化为：2x0-2x0*((P0)^0.5)*1/(Pn)^0.5则该做市商此时持有的净数字货币ETH盈亏为：
2*x0(P0/Pn)^0.5-2x0+2x0-2x0*((P0)^0.5)*1/(Pn)^0.5＝0
由此可见该做市商无论数字货币ETH的价格如何波动其净盈亏为0，说明通过本发明的合约交易装置几乎完全降低了无常损失，保证了用户数据和资产的安全性，使得做市商既可以长期无损失的持有数字货币ETH又可以赚取做市手续费和UNI代币，相当于实现了单一资产进行流动性挖矿。
在一个实施例中，如果该做市商想持有数字货币USDT，则可以选择按上述方法通过现有交易所的币本位合约中做空等值2x0个数字货币ETH即可以实现长期持有数字货币USDT而同时赚取做市手续费和UNI代币。
为了更加直观的体现做市商降低无常损失的风险，在一个实施例中，我们选择了2020年3月16至2020年9月1日的数据进行了回测，在2020年3月16向Uniswap中存入等值2个数字货币ETH，图2显示数字货币ETH价格从100美元涨至490美元，仅在Uniswap进行做市(流动性挖矿)，数字货币ETH的数量从2个降至0.903507903个，减少了一半多，对于想长期持有数字货币ETH的用户来说这种损失是无法接受的，而从一开始就选择在本合约交易装置进行交易，其净数字货币ETH数量一直维持2个不变，表明本合约交易装置完全降低了上述风险,实现了币本位的套期保值，保证了用户数据和资产的安全性。
在一个实施例中，用户持仓调整处理器还可以被配置为根据所述合约汇率Ph的c次幂的变化，使得交易用户的合约持仓量在连续的一个时间段内保持为折合第二资产B的数量为b/(Ph)^c的d倍,其中-1<c<0,b>0,d>0，b和c为预设常数，这样交易用户持仓量折合第二资产B的数量与价格变动保持一 致。
在一个实施例中，我们选取c＝-0.5,b＝1,即单份合约的价值折合第二资产B的数量为(Ph)^0.5,b和c一般使得b/(Ph)^c在0.1-1000美元之间，可以使得本合约交易装置更好的在区块链上运行，在数字货币ETH/数字货币USDT价格为P0时一个流动性挖矿用户向Uniswap资金池数字货币ETH-数字货币USDT存入x0个数字货币ETH和y0个数字货币USDT，同时在本发明合约交易装置中做空L＝2y0/(P0)^0.5份合约，即此时持有2y0个数字货币USDT的空单，当数字货币ETH/数字货币USDT价格波动到Pn时:
在Uniswap不考虑手续费的情况下满足：
x0＝(k/P0)^0.5
xn＝(k/Pn)^0.5
y0＝(kP0)^0.5
yn＝(kPn)^0.5
yn＝y0*(Pn/P0)^0.5
该流动性挖矿用户在Uniswap中数字货币USDT的变化为2yn-2y0＝2y0*(Pn/P0)^0.5-2y0
该流动性挖矿用户在本发明合约交易装置中数字货币USDT的变化为2y0-(2y0/(P0)^0.5)*(Pn)^0.5
则该流动性挖矿用户数字货币USDT净盈亏为2y0*(Pn/P0)^0.5-2y0+2y0-2y0/(P0)^0.5*(Pn)^0.5＝0
由此可见该做市商无论数字货币ETH的价格如何波动其数字货币USDT净盈亏为0，说明通过本发明的合约交易装置几乎完全降低了无常损失，保证了用户数据和资产的安全性，使得做市商相当于既可以长期无损失的持有数字货币USDT又可以赚取做市手续费和UNI代币，相当于实现了单一资产进行流动性挖矿,稳定币的套期保值。
为了更加直观的体现做市商降低无常损失的风险，在一个实施例中，如图3我们选择了2020年2月15至2020年3月13日的数字货币ETH/数字货币USDT数据进行了回测，在2020年2月15向Uniswap数字货币ETH-数字货币USDT资金池中存入等值1000数字货币USDT，图2显示数字货币ETH价格从290数字货币USDT跌至85数字货币USDT，该流动性做市商如果仅在Uniswap中做市，期间数字货币USDT亏损幅度高达43％，而选择同时在本发明合约交易装置中交易，期间净数字货币USDT保持为1000美元不变，表明本发明合约交易装置可以完全降低自动做市机制的无常损失风险，真正实现了自动做市商的套期保值，保证了用户数据和资产的安全性。
因此本合约交易装置还被配置为根据L*(P2^0.5-P1^0.5)计算所述交易用户交易保证金折合第一资产A或第二资产B的变化，P1为第一时刻第一资产A与第二资产B之间的汇率，所述P2为第二时刻第一资产A与第二资产B之间的汇率,所述L为所述交易用户在本合约交易装置的持仓份数。
所述Pq为所述交易用户的清算价格，所述P0为所述交易用户的开仓价格，u0为开仓保证金数量， m0为开仓资产放大率,交易用户从价格P0到Pq合约保证金变化为:
u0＝L(P0^0.5-Pq^0.5)，
所述交易用户在价格Pn时的保证金u为:
L(Pn^0.5–Pq^0.5)＝u0*(Pn^0.5–Pq^0.5)/(P0^0.5-Pq^0.5)。
在一个实施例中，我们可以选择交易保证金为第一资产A或第二资产B；
在一个实施例中，交易用户的交易保证金均为稳定币；
在一个实施例中，我们可以选择与第一资产A和第二资产B不同的A第二资产B，这样可以在不持有A和B的情况下，交易A和B的汇率,例如A为数字货币BTC，B为数字货币USDT，AB为数字货币ETH,这样我们可以通过持有数字货币ETH来交易数字货币BTC/USDT汇率。
在一个实施例中，合约交易装置还包括资产运算放大器，所述资产运算放大器将交易用户的资产放大率反馈给平仓处理器，所述交易用户的资产放大率为持仓价值与保证金价值之间的比值；本发明合约交易装置提供1-1000倍资产放大交易，交易用户通过资产运算放大器无需借贷就可以在持有少量保证金就可以交易较大金额从而实现了资金效率的提升，即所述交易用户的合约持仓量折合成保证金对应品种的数量大于所述交易用户保证金的数量和允许交易者在不持有资产本身的情况下推测资产的价格变动，所述交易用户合约持仓量价值的变化等于所述交易用户合约保证金的变化。本发明中的合约持仓量指的是对应交易标的的虚拟资产，因此交易用户的合约持仓量价值的变化会等于所述交易用户合约保证金的变化。
如做市商选择在本发明合约交易装置进行交易，拿出10％左右的资金在本系统中进行交易即可，极大的提高了资金利用率。
为了保证本合约交易装置和传统合约交易装置的近似性，所述交易用户的初始资产放大率被设定为m0,优选的，|((m0-1)/m0)^2–(m0-2)/m0|<11.11％，
其中((m0-1)/m0)^2为本合约交易装置第一设定价格Pq和第二设定价格P0之间的比值，其中(m0-2)/m0为传统合约交易装置第一设定价格Pq和第二设定价格P0之间的比值，可选的，第一设定价格为交易用户的清算价格，第二设定价格P0为交易用户的开仓价格，则|((m0-1)/m0)^2–(m0-2)/m0|差值越小，两种合约交易装置越相近；
为了避免穿仓风险，即穿过清算价格，所述所述资产运算放大器实时的将交易用户的资产放大率反馈给平仓处理器，当资产放大率过高时，也可以发提醒给交易用户进行风险提示，超过系统设定的资产放大率阈值，将向交易引擎发起强制平仓指令，即用户仓位产生爆仓。
当第二设定价格为第一价格Pn时，则满足：
Pq/P0＝((m0-1)/m0)^2
Pq/Pn＝((m-1)/m)^2
则在第一价格Pn时本合约交易装置还将配置为使得交易用户的资产放大率
m＝m0*Pn^0.5*(P0^0.5+m0(Pn^0.5-P0^0.5))。
在一个实施例中，本发明所述交易引擎还包括虚拟定价系统，所述虚拟定价系统包括虚拟品种C和虚拟品种D，所述虚拟品种C的虚拟价值折合第一资产A的数量与合约汇率Ph负相关，折合第二资产B的数量与合约汇率Ph正相关，所述虚拟品种D的虚拟价值与第一资产A或第二资产B的价格正相关，所述撮合交易包括根据所述虚拟定价系统确定所述交易用户的成交价；优选的，所述虚拟品种C的数量x和虚拟品种D的数量y满足xy＝k,k为常数。
在一个实施例中，本发明合约交易装置还包括交割系统，所述交割系统用于对于所述合约约定的交割日期进行平仓；这样可以在本合约交易装置上发布定期合约产品，定期合约会在固定时间进行强行交割。
为了确定交割价格，所述交割系统包括交割价格计算系统，所述交割价格计算系统在交割前通过向现货行情服务器网关发起查询，根据查询到的现货汇率Px以确定交割价格；
这里的现货行情服务器既可以是中心化的交易所，如币安、火币、OKEX等中心化交易所，也可以是去中心化交易所，如Uniswap、Curve、SushiSwap、Balancer、Kyber Network等，具体可以参考 https://debank.com/ranking/dex，当然现货行情服务器并不限于是交易所，还可以是提供报价的第三方报价平台，如tradingview、aicoin等，或者从基于区块链的预言机Link等获取现货价格信息。
在一个实施例中，本发明合约交易装置还包括资金费率管理器，所述资金费率管理器用于在固定时间对做多用户或做空用户收取资金费率；
所述资金费率管理器采用的费率收取方式包括：当合约汇率Ph相对于现货汇率出现正溢价时，对做多用户收取资金费率，对做空用户补贴资金费率；当合约汇率Ph相对于现货汇率出现负溢价时，对做空用户收取资金费率，对做多用户补贴资金费率；通过以上方式，使得交易价格有效锚定现货价格，使得交易用户不用通过交割移仓的方式，就可以一直持仓相关仓位。
在一个实施例中，本发明合约交易装置可选的交易标的可以包括比特币对稳定币的汇率、以太坊对稳定币、稳定币对稳定币的汇率中的一个或多个；

为了在区块链上实现本发明的合约交易装置，在一个可选的实施例中，建立以下智能合约：一个交易用户1在价格P1时锁定保证金B1同时生成单份合约价值的整数倍的非同质化代币Coin+(P1,B1,H1)n1个，另一个交易用户2在价格P2时锁定保证金B2同时生成单份合约价值的整数倍的非同质化代币Coin-(P2,B2,H1)n2个，
交易用户1向交易用户2转账，交易用户2收到代币Coin+(P1,B1,H1)n1个，当P1＝P2时，且n1>＝n2时，将生成同质化(n1-n2)个代币Coin±(P1,B1,H1),同时湮灭掉n1个Coin+(P1,B1,H1)和n2个Coin-(P1,B1,H1)，此时交易用户2持有(n1-n2)个代币Coin±(P1,B1,H1)和(n1-n2)个Coin+(P1,B1,H1)，如果交易用户2在价格P3时，在价格P3时锁定保证金B2同时生成单份合约价值的整数倍的非同质化代币Coin-(P2,B2,H2)(n1-n2)个,当P3>P1时交易用户2中的(n1-n2)个代币Coin±(P1,B1,H1)和Coin-(P2,B2,H2)将被湮灭掉，同时进行盈亏结算，交易用户2将获得盈利的保证金，
这里的湮灭表示该数量的代币清零且释放保证金，上述非同质化代币均锁定了相应数量的保证金。这种采用非同质化代币的智能合约工作模式，使得每个数字货币钱包均具有了交易所的功能，不仅仅适用于本发明的合约交易装置，也适用于其他合约交易装置，如线性合约，反向合约，期权合约，期货合约等。
在一个实施例中，本发明还提供一种由至少一个计算机处理器组成的合约交易装置执行的非同质化代币的创建方法，所述创建方法包括：

用户持仓调整处理器，所述用户持仓调整处理器被配置为根据所述合约汇率Ph的变化，使得交易用户的合约持仓量在连续的一个时间段内折合第一资产A的数量与合约汇率Ph负相关，折合第二资产B的数量与合约汇率Ph正相关；
这里需要说明的是，在连续的一个时间段内，表示持仓量上述关系的变化具有可持续性，比如所述交易用户的持仓时间大于自动做市商在区块链上一个区块的时间。
交易数据存储器，所述交易数据存储器包括用于存储交易用户的基本信息；
资金池持仓调整处理器，所述资金池持仓调整处理器用于在所述合约汇率达到预设值时对所述的合约持仓量发起强制加仓或减仓指令。
可选的，所述加仓等效为向自动做市商如Uniswap等提供流动性的过程，减仓为退出流动性的过程；
可选的，所述减仓等效为向自动做市商如Uniswap等提供流动性的过程，加仓等效为退出流动性的过程；可选的，所述加仓或减仓为增加或减少所述的合约持仓量。
可选的，所述用户持仓调整处理器被配置为根据所述合约汇率Ph的c次幂的变化，使得交易用户的合约持仓量在连续的一个时间段内保持为折合第一资产A的数量为b/(Ph)^c的d倍,其中0<|c|<1,b>0,d>0，b和c为预设常数。
在一个实施例中所述合约交易装置，还包括凭证生成器，所述凭证生成器被配置为在所述资金池管理器收到第一资产A或第二资产B的存入后生成第一凭证，或被配置为在所述交易用户与资金池之间建立交易后，生成第二凭证，所述第一凭证与所述资金池中第一资产A或第二资产B数量正相关，所述第一凭证被配置为用于向资金池发起取款请求的凭证，所述第二凭证与所述交易用户与所述资金池之间的合约持仓量在连续的一个时间段内正相关，所述第二凭证被配置为用于释放所述交易用户保证金的凭证。
所述第一凭证和第二凭证可以为去中心化的数字货币。
可选的，所述第一凭证代表的资金量折合成第二资产B的数量大于等于所述第二凭证代表的持仓量折合成第二资产B的数量。这里第一凭证代表的资金量表示，本合约交易装置资金池有多少资金量则第一凭证有多少，例如资金池中有1000USDT，则第一凭证代表1000USDT，而第二凭证则代表的是交易用户的合约持仓量，如一份合约的价值为P^0.5USDT,P＝100时，交易用户持仓量为20份合约，则持仓量代表的资金量为200USDT，则第二凭证则代表交易用户持仓200USDT。
可选的，所述合约交易装置还包括凭证销毁器，所述凭证销毁器被配置为在凭证持有用户向所述合约交易装置发起取款请求后，销毁第一凭证或第二凭证。
下面以一个具体实施例说明一下本合约交易装置的工作原理，如图4所示，以数字货币ETH和USDT 为例，在本合约交易装置模式下，流动性挖矿用户向本合约交易装置资金池存入数字货币USDT后，生成相应数量的数字货币SL_USD给流动性挖矿用户，SL_USD为取款凭证，相当于第一凭证，即任何持有SL_USD的用户均可以向本合约交易装置发起取款请求，取款后，用户将得到相应数量的数字货币USDT，同时销毁相应数量的数字货币SL_USD；
交易用户向合约交易装置发起交易请求时，将冻结一定数量的保证金，建立交易用户和资金池之间的对手交易，本合约交易装置将单份合约的价值设置为P^0.5个USDT,P为数字货币ETH兑USDT的汇率，这里还可以给交易用户提供一定的资产放大率，如5倍资产放大率，则冻结的USDT保证金数量为交易量V的1/5即可，
合约交易装置在接收到交易请求后，建立交易用户和资金池的对手交易，随后资金池将取出所述交易量相对应的USDT，将USDT发送到Uniswap等自动做市商的资金池ETH-USD中,将其中V/2的USDT兑换成ETH，随后将兑换好的ETH和剩余的V/2的USDT存入资金池ETH-USD中，此时相应数量的数字货币L_ETH给交易用户，L_ETH为取款凭证，相当于第二凭证，即任何用户持有L_ETH的用户均可以向本合约交易装置发起解冻保证金的请求，保证金将释放给该用户，同时销毁相应数量的数字货币L-ETH,
由于交易用户仅冻结了少于交易量的保证金，那么数字货币L_ETH的价格波动将比ETH更大，例如，给交易用户提供m倍的资产放大率时，这里的资产放大率等于开仓价值/保证金价值，当m较大时，如m>3,那么L_ETH的波动将约为ETH波动的m/2倍，那么L_ETH相当于一个追踪ETH价格并看多ETH的放大型数字货币，为了进一步提高L_ETH的与ETH的相关性，交易用户的初始资产放大率被配置为m0,则|((m0-1)/m0)^2–(m0-2)/m0|<11.11％，此时L_ETH的涨跌与ETH的涨跌相关性最高，比如ETH上涨5％，则L_ETH将上涨近似于15％；
而SL_USD与USDT为等价兑换，则SL_USD相当于通过本合约交易装置自动铸造的一个锚定USDT的稳定币。由于交易用户的保证金会随着ETH价格变化而发生盈亏，即交易用户的资产放大率也会跟随价格在动态变化，为了保证交易系统的稳定运行，对于交易用户的资产放大率设置一个预设范围(m1,m2)，当交易用户的资产放大率超过上述预设范围时，通过资产运算放大器将交易用户的资产放大率调整至所述预设范围内。
可选的，当m>m2时，合约交易装置将自动向如uniswap等自动做市商系统发起取款和兑换操作，同时将ETH兑换成USDT存入合约交易装置的USDT资金池中，此时相当于交易用户和资金池合约持仓的资产放大率下降了，当m<m1时，合约交易装置将自动向如uniswap等自动做市商系统发起兑换和存款操作，将USDT发送到Uniswap等自动做市商的资金池ETH-USD中,将其中Vp/2的USDT兑换成ETH，随后将兑换好的ETH和剩余的Vp/2的USDT存入资金池ETH-USDT中，此时相当于交易用户和资金池合约持仓的资产放大率上升了。
为了进一步增加本合约交易装置的活跃性，可以在uniswap等自动做市商开设L_ETH-SL_USD和SL_USD-USDT的资金池，方便相关持有者进行交易，当ETH价格下跌时，将有更多的交易用户向本合约交易装置发起交易请求以得到L_ETH，到资金池L_ETH-SL_USD进行抛售，然后将兑换得到的SL_USD向合约交易装置发起取款请求，以得到USDT，整个过程在L_ETH-SL_USD价格未变动前，则相当于实现了一次套利操作，得到更多的USDT，当ETH价格下跌时，则执行相反的操作即可,为了保证SL_USD价格的稳定性，当SL_USD/USDT>预设值p1时，系统进行SL_USD等比例的增发，当SL_USD/USDT<预设值p2时,系统进行SL_USD等比例的通缩。
在一些实施例中交易对手均为交易用户，而在该实施例中，交易对手一方为交易用户，一方为资金池，因此可以在没有订单簿的情况下实现，即可以完全运行在区块链系统上，实现了完全降低无常损失，保证用户数据和资产的安全性，发行去中心化的放大型数字货币和稳定币的技术效果，该放大型数字货币和稳定币均有对应的底层资产，可以在没有预言机的情况下实现数字货币的放大化和锚定稳定币的效果。
在另一实施例中，还是以数字货币ETH和USDT为例，在本合约交易装置模式下，流动性挖矿用户向本合约交易装置资金池存入数字货币ETH后，生成相应数量的数字货币SL_ETH给流动性挖矿用户，SL_ETH为取款凭证，相当于第一凭证，即任何持有SL_ETH的用户均可以向本合约交易装置发起取款请求，取款后，用户将得到相应数量的数字货币ETH，同时销毁相应数量的数字货币SL_ETH；交易用户向合约交易装置发起交易请求时，将冻结一定数量的保证金，建立交易用户和资金池之间的交易，本合约交易装置将单份合约的价值设置为1/P^0.5个ETH,P为数字货币ETH兑USDT的汇率，这里还可以给交易用户提供一定的资产放大率，如5倍放大率，则冻结的ETH保证金数量为交易量V的1/5即可，
合约交易装置在接收到交易请求后，建立交易用户和资金池之间的对手交易，随后资金池将取出所述交易量相对应的ETH，将ETH发送到Uniswap等自动做市商的资金池ETH-USD中,将其中V/2的ETH兑换成USDT，随后将兑换好的USDT和剩余的V/2的ETH存入资金池ETH-USDT中，此时相应数量的数字货币L_ETH给交易用户，L_ETH为取款凭证，相当于第二凭证，即任何用户持有L_ETH的用户均可以向本合约交易装置发起解冻保证金的请求，保证金将释放给该用户，同时销毁相应数量的数字货币L-ETH,
由于交易用户仅冻结了少于交易量的保证金，那么数字货币L_ETH的价格波动将比ETH更大，例如，给交易用户提供m倍的资产放大率时，这里的资产放大率等于开仓价值/保证金价值，当m较大时，如m>3,那么L_ETH的波动将约为ETH波动的m/2倍，那么L_ETH相当于一个追踪ETH价格并看空ETH的放大型数字货币，为了进一步提高L_ETH的与ETH的相关性，交易用户的初始资产放大率被配置为m0,则|((m0-1)/m0)^2–(m0-2)/m0|<11.11％，此时L_ETH的涨跌与ETH的涨跌相关性 最高，比如ETH下跌5％，则L_ETH将上涨近似于15％；
而SL_ETH与ETH为等价兑换，则SL_ETH相当于通过本合约交易装置自动铸造的一个ETH锚定币。由于交易用户的保证金会随着ETH价格变化而发生盈亏，即交易用户的资产放大率也会跟随价格在动态变化，为了保证交易系统的稳定运行，对于交易用户的资产放大率设置一个预设范围(m1,m2),当交易用户的资产放大率超过上述预设范围时，通过资产运算放大器将交易用户的资产放大率调整至所述预设范围内。
可选的，当m>m2时，合约交易装置将自动向如uniswap等自动做市商系统发起取款和兑换操作，同时将USDT兑换成ETH存入合约交易装置的ETH资金池中，此时相当于交易用户的资产放大率下降了，当m<m1时，合约交易装置将自动向如uniswap等自动做市商系统发起兑换和存款操作，将ETH发送到Uniswap等自动做市商的资金池ETH-USD中,将其中Vp/2的ETH兑换成USDT，随后将兑换好的USDT和剩余的Vp/2的ETH存入资金池ETH-USD中，此时相当于交易用户的资产放大率上升了。
为了进一步增加本合约交易装置的活跃性，可以在uniswap等自动做市商开设L_ETH-SL_USD和SL_ETH-ETH的资金池，方便相关持有者进行交易，当ETH价格上涨时，将有更多的交易用户向本合约交易装置发起交易请求以得到L_ETH，到资金池L_ETH-SL_ETH进行抛售，然后将兑换得到的SL_ETH向合约交易装置发起取款请求，以得到ETH，整个过程在SL_ETH-ETH价格未变动前，则相当于实现了一次套利操作，得到更多的ETH，当ETH价格下跌时，则执行相反的操作即可,为了保证SL_ETH价格的稳定性，当SL_ETH/ETH>预设值p1时，系统进行SL_ETH等比例的增发，当SL_ETH/ETH<预设值p2时,系统进行SL_ETH等比例的通缩。
在订单簿模式下交易对手均为交易用户，而在该实施例中，交易对手一方为交易用户，一方为资金池，因此可以在没有订单簿的情况下实现，即可以完全运行在区块链系统上，实现了完全降低无常损失，保证了用户数据和资产的安全性，发行去中心化的放大型数字货币和锚定币的技术效果，该放大型数字货币和锚定币均有对应的底层资产，可以在没有预言机的情况下实现数字货币的放大化和数字货币锚定币的效果。
在一个实施例中，本发明还公开一种区块链系统，所述区块链系统被配置为参与执行或触发执行上述合约交易装置中的可执行程序。
在一个实施例中，本发明还提供一种由至少一个计算机处理器组成的合约交易装置执行的放大资产的创建方法，包括：

由合约持仓调整处理器根据所述现货汇率Px的变化，将所述放大资产的合约持仓价值调整为折合第一资产A的数量与现货汇率Px负相关，折合第二资产B的数量与合约汇率Px正相关。
在一个实施例中，所述创建方法还包括：由资产运算放大器将所述放大资产的初始资产放大率配置为m0,满足：Pq/P0＝((m0-1)/m0)^2,所述Pq为清算价格，所述P0为开仓价格，所述资产放大率为所述放大资产的合约持仓资产价值与保证金价值之间的比值。

在一个实施例中，所述非同质化代币的属性至少包括所述放大资产的合约持仓份数和所述合约持仓价格。
在一个实施例中，本发明还公开一种区块链系统，所述区块链系统被配置为参与执行或触发执行所述放大资产的创建方法。
为了在区块链上给交易用户对手方的撮合交易进行定价，在一个实施例中，本合约交易装置还包括虚拟定价系统，所述虚拟定价系统包括资金池虚拟第一资产VA-虚拟第二资产VB，所述虚拟第一资产VA和虚拟第二资产VB的初始数量分别为x0和y0，则x0y0＝k，k为预设值，当保证金为第二资产B时，为了确定交易用户第一资产A和第二资产B的合约汇率Ph的成交价，合约交易装置在 接受到交易用户开仓量为V的交易时，虚拟交易系统将生成交易量等值的虚拟第二资产Bz个，将其中n2个虚拟第二资产B兑换成虚拟第一资产An1个，使得满足：
兑换前:x0y0＝k0
兑换后：(x0+n1)(y0-n2)＝k0
存入前后：(y0+z-n2)/(x0+n1)＝(z-n2)/n1
将n1个虚拟A和z-n2个虚拟B存入虚拟自动做市资金池A-B中，则所述交易用户的开仓合约汇率为Ph＝n2/n1。
当合约交易装置在接受到交易用户平仓量为V的交易时，价值折算为第二资产B的数量为z个，虚拟做市交易系统将n1个虚拟第一资产A和Z-n2个虚拟第二资产B从资金池中取出，然后将n1个虚拟第一资产A兑换成n2个虚拟第二资产B，则此时将z个虚拟第二资产B销毁，使得满足：
取出前后：y0/x0＝(y0-z+n2)/(x0-n1)
兑换前：(x0-n1)(y0-z+n2)＝k1
兑换后：(x0-n1+n1)(y0-z+n2-n2)＝k1
则所述交易用户的平仓合约汇率Ph＝n2/n1＝(y0-z)/x0。
为了在区块链上给交易用户对手方的撮合交易进行定价，在一个实施例中，本合约交易装置还包括虚拟定价系统，所述虚拟定价系统包括资金池虚拟VC品种和虚拟第二资产VB，其中虚拟VC品种的价值为折合第一资产VA的数量为b/(Ph)^c的d倍,其中0<|c|<1,b>0,d>0，b和c为预设常数。下面以以数字货币ETH和USDT为例，说明一下虚拟定价系统的工作原理，如图5所示，这里第一资产VA为ETH，第二资产VB为USDT，单个VC品种的价值定义为P^0.5USDT,则虚拟定价系统，包括资金池虚拟C(P^0.5)-虚拟USDT，其虚拟VC品种为x个和虚拟USDT为y个，满足：xy＝k，当本发明合约交易装置接收到交易用户的交易请求后，开仓量为v份做多或平空的P^0.5合约，那么向资金池虚拟VC(P^0.5)-虚拟USDT购买v个虚拟VC(P^0.5)，那么资金池满足：
兑换前:xy＝k
兑换后:(x-v)(y+y1*m)＝k
其中y1为合约保证金，m为开仓资产放大率，则合约成交价为Ph＝(P^0.5)^2＝(y1*m/v)^2。
当开仓量为v份做空或平多的P^0.5合约，那么向资金池虚拟C(P^0.5)-虚拟USDT出售v个虚拟C(P^0.5)，那么资金池满足：
兑换前:xy＝k
兑换后:(x+v)(y-y1*m)＝k
其中y1为合约保证金，m为开仓资产放大率，则合约成交价为Ph＝(P^0.5)^2＝(y1*m/v)^2。
根据以上虚拟定价系统可以实现在没有订单簿的情况下确定交易用户的合约交易的成交价，适合在区 块链上实现本合约交易装置。
以上所述仅是本发明的实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以作出若干改进和润饰或组合，这些改进和润饰也应视为本发明的保护范围。
