抽奖活动
抽奖活动方案:每天中午12点取bitfinex上btc/usd的收盘价做为随机数,然后计算出中奖时间。
计算细则:1.将去除小数后的美元价格除以60的余数作为随机数A,而美分位的奇偶作为随机数B,随机数A决定在最近24小时内这一分钟买入的用户中奖,随机数B的奇偶性决定是奇数小时还是偶数小时的用户才能中奖。
2.如果获奖用户在最近24小时内有卖出行为则取消获奖资格。
3.中奖用户平分奖金,奖金总额为开奖时保障池池余额的1%。
计算公式:设收盘价为P,则A(分钟)= int(P) mod(60),int为取整函数,mod为取余操作。B=odd(P*100),odd为奇偶性函数。最后中奖结果是:B:A

HOW O2 WORKS

O2 is the first truly decentralized digital payment instrument that utilizes the natural attributes of the cryptocurrency.

Application scenario:
Capital management and control

The O2 payment can be carried out between A and B, or among A, B and C.The original payer A can define the usage of the funds and ensure that B fully complies with the agreement. A unlocks the funds only after B completes the payment transfer to C. The unique payment characteristics of O2 make itself to be transferable, so it can be widely used tuition payments, agency-oriented subsidies and the use of funds

Application scenario:
Cross-border trade

The adoption of the O2 trading model enables both the buyer and the seller to complete cross-border settlement in a timely manner with very low trans action costs, without the need to ensure credit of the transaction by any financial institutions, nor to exchange money between different fiat money due to country differences to incur additional costs. The buyer of a cross-border trade unlocks the transaction only after receiving the goods and confirm ing their quality, and the seller of the cross-border trade will not lose their assets due to the buyer's integrity.
