共生经济基金会和挖矿浏览器是什么关系?
共生经济基金会开发出挖矿浏览器,支持挖矿(正常使用挖矿浏览器挖取共生币)。

What is the relationship between the symbiotic economy foundation and the mining browser?
The symbiotic economy foundation has developed a symbiosis browser to support mining (normally using the symbiosis browser).

什么是共生经济?
共生链是由共生经济基金会及其技术合作团队打造的一个新型区块链项目,其目标是打造一个全新基于区块链技术的商业模式——共生经济模式。共生经济是指独立的经济组织之间以同类资源共享或异类资源互补为目的会形成共生体,这种共生体的形成所导致的经济组织内部或外部的直接或间接的资源配置效率的改进。共生链所打造的共生经济是一种让商家与用户双方获益,相互促进、共同成长、共生共荣的经济共生体。

What is a symbiotic economy?
The symbiotic chain is a new block chain project developed by the symbiotic economy foundation and its technical cooperation team. Its goal is to create a new business model based on block-chain technologies – a symbiotic economy.

共生链有什么用?
共生链的建立,源于用户的网络价值被忽视,用户在使用互联网过程中,账户注册、创造内容、浏览网页、评价分享、网上购物等行为都在创造价值,它增加了网站的活跃、留存,甚至付费转换,但是用户没有任何获得。共生链是希望将所有互联网应用联合在一起形成共生系统。共生链是建设于虚拟网络的新的经济体系,在这个体系里,消费者和商家基于利益,组成一个共生系统生态圈。在生态圈中,每一个实体都会被作为一个锚点,追踪记录其贡献价值和信用,每天根据动态算法,以共生币的形式获得利益分配。

What is the use of symbiotic chains?
is the creation of symbiotic chains that result from the neglect of the value of the user’s network. In using the Internet, users are creating value by registering accounts, creating content, browsing web pages, evaluating sharing, online shopping, etc., which increases the website’s activity, retention, or even fee conversion, but not by the user. The symbiotic chains are intended to combine all Internet applications into a symbiotic system. The symbiotic chain is a new economic system built into virtual networks, in which consumers and traders form an ecosystem based on interest. In the biosphere, each entity is used as an anchor to track its contribution value and credit, and is allocated benefits on a daily basis in the form of symbill based on dynamic algorithms.

共生链的发展大致分为两个阶段,
即半人马宇宙和悟空宇宙阶段。

The symbiotic chain is developed in two phases,

    2020年12月,让5亿网民成为共生经济受益者。

共生币有何独到之处?
更公平、更灵活、更安全、有落地、成长快、升值空间大

What's so special about symbiosis?

共生币总量有多少?如何分配?
共生链坚持面向未来的先进的价值观,坚持开放、透明、民主、去中心化的原则。共生币将成为共生经济的硬通货。为广大用户凝聚价值,让大众用户能够与商家一起分享新经济形态带来的高额红利。共生币总发行量为280亿,其中30%分配给投资人,20%分配给创始团队,10%用于推广传播,10%预留给生态厂商,30%通过挖矿方式分发。每年通过挖矿产生的共生币都将比前一年降低40%。创始团队拥有的共生币每年解锁不超过2%。

The symbiotic chain is based on advanced values for the future, and on the principles of openness, transparency, democracy, and decentralisation. The symbiotic currency will become a hard currency of the symbiotic economy. The value of the combi will be condensed for a wide range of users, allowing the public to share with the business the high dividends of the new economic model. The symbith is distributed at $28 billion, of which 30% is allocated to investors, 20% to the founding team, 10% to the extension, 10% to the ecological company, and 30% to the mining industry. The symbi generated through mining will be reduced by 40% per year compared to the previous year.

共生币如何升值?
稀缺性、 流通性、生态系统发展带来的升值

How does the symbiosis appreciate?
The appreciation of scarcity, circulation, ecosystem development.

共生币合法吗?
共生币参照莱特币等知名加密数字货币,将在私募完成后于新加坡成立Public Company Limited by Guarantee非盈利基金会,该基金会的主要任务是公开、公正和透明地运营共生币生态,并对共生币的开发团队进行支持。共生经济基金会将由新加坡会计与企业管理局(ACRA)批准成立,受新加坡公司法监管,该基金会由具备受托资格人组成的受托董事会或管理委员会独立管理运营并独立于政府之外。

Is the symbiosis legitimizing?
The symbiosis is based on well-known encrypted digital currencies, such as the Leit currency, and will be established in Singapore after the completion of the private collection, with the main task of operating the symbiology in an open, fair and transparent manner and supporting the development team of the symbiosis. The symbiosis is to be approved by the Singapore Accounting and Enterprise Authority (ACRA) and regulated by the Singapore Corporate Law, which operates independently of the government by a board of trustees or management board of trustees.

共生币的POV(proof-of-value)挖矿方案有何独到之处?
不同于比特币的POW共识方案和以太坊的POS共识方案。共生链将采用POV(Proof-Of-Value)的共识方案。用户(挖矿)获得的共生币奖励的多寡将由他对共生系统所产生的贡献来决定。

What's so special about the cosmopolitan POV (proof-of-value) mining program?
is different from the Bitcoin Pow consensus program and the Ether POS consensus program. The symbiotic chain will be based on the Proof-Of-Value consensus scheme. The size of the cosmopolitan reward received by the user (digger) will be determined by his contribution to the symbiotic system.

共生币的挖矿规则是怎样的?
共生币发行总量的30%将能通过挖矿获得,共计84亿个共生币,而挖矿共分为2个阶段:
第一个阶段是预热期,在此期间,每天将有1千万共生币通过挖矿产生。所有使用了挖矿程序并满足一定条件的活动参与者(矿工)将分享每天产出的共生币。
第二阶段是正式期,在此期间,剩余的79亿个共生币将会在规定时间内通过挖矿的形式逐步发放完毕。每年通过挖矿获得的共生币数量都将比前一年降低40%。

What are the rules for the mining of symbiotic coins?
30% of the total amount of symbiosis will be obtained through mining, amounting to 8.4 billion symbiths, while mining will be divided into two phases: The second phase is official, during which the remaining 7.9 billion symbills will be distributed gradually in the form of excavation within the specified time frame. The number of symbills obtained through mining will be reduced by 40% from the previous year.

获得最多共生币的最佳挖矿小技巧:
1、更换自己使用的浏览器为挖矿浏览器。
2、将挖矿浏览器设置为默认浏览器,在浏览器内使用默认的搜索引擎等。
3、每天持续使用挖矿浏览器,没有一日中断。使用时长越长,获得共生币越多。
4、如果您具有开发能力,可以基于共生币开发相关应用。

Obtains the best mining technique for the maximum symbiotic coins:
1, replaces the browser you use as a mine browser.
2, sets the excavator browser as a default browser, uses the default search engine in the browser, etc.
3, continues to use the mine digger on a daily basis, without interruption for a single day. The longer the use takes, the more the symbiosis is obtained.
4, if you have the capacity to develop, you can develop applications based on symbiotic currency.

共生币是什么?
共生币(LVT,英文全称LivesToken)是共生经济基金会为了倡导和促进未来经济形态——“共生经济”的发展和壮大,在共生经济平台上基于先进的区块链技术开发的去中心化的加密数字货币。

What are symbiotic coins?
Cosymbills (LVT, full English-named LivesToken) are decentralised digital currencies developed on a symbiotic economic platform based on advanced block chain technology to promote and promote the development and growth of future economic patterns — the “symbiotic economy”.

共生币有什么用途?
与比特币、以太坊等一样,加密数字货币具有的基本功能它都有,可以在全球范围内不受限制地交易和流通,而且共生币还能为任何人在互联网上付出的行为、时间等进行定价、折现,成为使用共生经济体系内一切平台、服务和交易的凭证。共生币凝聚、固化任何人在互联网上付出的普通劳动和创造性劳动的价值。未来是共生经济的时代,共生币是最好的投资。

What is the use of symbiosis? Like Bitcoin, Etheria, etc., the basic function of encrypted digital money is that it can be traded and circulated without restriction on a global scale, and the symbiosis can also be priced and discounted for any person’s behavior, time, etc. on the Internet, and can be used as evidence of the use of all platforms, services and transactions within the symbiotic economy. The symbiosis, cementing the value of ordinary and creative work that anyone pays on the Internet, is the best investment. The future is the time of the symbiotic economy, and the symbi is the best investment.

如何获得共生币?
共生币通过自己独创的POV(Proof-Of-Value)协议进行分发。通过挖矿浏览器进行挖矿,获得分发的共生币,为共生经济做贡献。正常使用挖矿浏览器,就能获得共生币。注册共生账号,注册挖矿浏览器账号,使用挖矿浏览器登录浏览器账号,将浏览器账号绑定共生账号,即可进行挖矿。

How do you get symbiotic coins?

共生币发放机制是怎样的?
共生币总发行量280亿,其中30%(84亿)通过挖矿方式分发,30%分配给投资人,20%分配给创始团队,10%用于推广传播,10%预留给生态厂商。每年通过挖矿产生的共生币都将比前一年降低40%。创始团队拥有的共生币每年解锁不超过2%。共生币挖矿包含预热期、正式期两大阶段:预热期(2018年1月月底全球开启)每天1千万共生币,持续至4月30日。预热期结束后紧接着正式期,79亿共生币在规定年限内通过挖矿的方式逐步分发完毕。

The cosmopolitan currency distribution mechanism is 28 billion dollars, of which 30 per cent (84 billion) is distributed through mining, 30 per cent to investors, 20 per cent to starters, 10 per cent to promote dissemination, and 10 per cent to eco-makers. The cosmbi generated through mining will be reduced by 40 per cent each year compared to the previous year. The cosmogical coins held by the founding team will not be unlocked by more than 2 per cent each year. The cosmopolitan mine involves both periods of pre-heat and formal periods: the pre-heating period (global opening at the end of January 2018) will last until 30 April.

共生币如何交易?
当前,您可以在共生社区求购、出售共生币,可以把共生币推介给亲朋好友或发布到其他数字货币社区。不久后共生链会开放C2C交易平台(依当时政策而定),并登陆海内外各大交易所。共生币交易方式会越来越多,请屏息静候。

The symbiotic chain will soon open the C2C trading platform (depending on the policy at the time) and will land on major exchanges within and outside the country.

  1. Q:锁仓是什么?
    A:锁仓是指用户自己将部分资产通过自定义数量和时间,设置锁仓合约,将资产冻结,锁仓资产不可转账,不可提币。

    Q: What is a lock-out?
    A: Lock-up refers to the user's own use of a customized quantity and time, the setting up of a lock-out contract, the freezing of assets, the non-transferability of lock-up assets and the non-transferability of currency.

  2. Q:锁仓算力奖励是如何计算的?算力加成与现有默认算力值有关系吗?
    A:锁仓算力=锁仓数额/100000锁仓期限0.2*100%,锁仓算力奖励与锁仓数额和锁仓时间有关,锁仓数额越大,锁仓时间越长,则锁仓算力加成值越大; 锁仓算力加成是在现有默认算力值基础上进行加成的,允许一个用户有多个锁仓资产,最多可加成500%,超出部分无奖励。

    Q: Q: How does the lock-up incentive be calculated? Does the build-up relate to the existing default value?
    A: the lock-up factor = 100 per cent of the lock-up amount 0.2* 100 per cent of the lock-up period < /em>, the lock-up incentive relates to the lock-up amount and the lock-up time, the larger the lock-up amount and the longer the lock-up time, the greater the build-up value of the lock-up factor;

  3. Q:若未达到锁仓期限就解除锁仓,违约金是怎么计算的呢?
    A:违约罚金=(锁仓剩余月份/锁仓期限)0.5锁仓金额,待支付违约金与锁仓解除时间、锁仓期限和锁仓金额有关,锁仓金额越大,剩余锁仓月份越多,则需支付的违约金则越大。

    Q: If the lock-down period is not met, how does the default amount be calculated?
    A: the default penalty = the amount of the lock-up (the remaining month/the lock-up period) 0.5 >, the more the default amount is due, the greater the amount of the lock-up and the more the remaining lock-up month.

  4. Q:解除锁仓当天,未解除锁仓状态的时间算力加成有效吗?
    A:有效的。

    Q: On the day when the locking is lifted, does the amount of time that has not been unlocked become effective?
    A: effective.

  5. Q:计算违约金时,违约月份包含当前月份吗?
    A:包含;一般来说,解除锁仓越早,则违约金越高。

    Q: When calculating the default amount, does the default month include the current month?
    A: Include; generally, the sooner the lockup is lifted, the higher the default amount.
