Ontropy團隊在 5 月份獲得數百萬美元的種子倫投資，且可能是來自幣安孵化的，已公布有代幣ORB，有空投機會，可以多關注，想更了解項目，歡迎繼續往下看

什麼是 Ontropy?

Ontropy 目標通過消除預言機、生成可驗證的隨機性並實現”鏈下”共識來分散數據，Ontropy 將作為我們”個人”的區塊鏈，什麼是意思呢? 是指使用者也是驗證者，而且 ontropy 將會基於 OP 或 ZK 的技術上，這確保了用戶一定的安全性，因為不存在驗證者，所以速度會相對變快且幾乎沒有手續費，因為他們使用了 POR (proof of result) 來作為驗證方式，等一下會有相關解釋。

目標是什麼?

Ontropy 主要目標是在任何鏈上部署即時、無縫交易，因為有無縫交易、低手續費、快速、隱私的特點，適合賭博類遊戲、web3 社交、訂單簿、期貨市場等…

POR(proof of result) 技術簡介

以下是官方給出的兩分鐘解釋 POR，在我看來不只兩分鐘阿，而且更難懂，建議直接跳過，我用更簡單的方法解釋給你聽。

PoR Explained in Two Minutes

Let us simplify Proof of Result with an analogy where a car is ETH, a garage is smart contract code, and signed messages represent Proof of Result. 

So imagine that someone owns a car and wants a loan. This person may post a listing, valuing the car at $5,000 as collateral. 

A stranger checks other listings, confirms \(5,000 is the going rate, and replies, agreeing to lend \)2,000. The borrower parks the car in a garage that neither of them own. The borrower and lender exchange signed written messages that mutually confirm their agreement to the \(5,000 valuation and \)2,000 loan amount, along with a one-month repayment window.

Both the borrower and lender return to the garage after one month. In the first outcome, the borrower has $2,000 and pays it back to the lender through the garage. The lender cannot claim that the amount is not enough, as the borrower still has the lender’s signed message. The borrower can show the signed message to the garage and they will be given back their car.

In the second outcome, both return to the garage, but the borrower does not have the \(2,000 to pay the lender. The lender will show the signed message of the \)2,000 payment to the garage. Because the borrower’s signed message agreed to a time, the lender can take possession of the car if the garage has not detected a payment.

The lender, however, cannot attempt to steal the car before the agreed time has passed because the garage will check the timestamp. The borrower can also collect the car anytime before without the consent of the lender through the proof of payment.

Okay, let’s bring this analogy back to DeFi where a user wants to borrow against their ETH. The problem is, the price of Ethereum is quickly changing and is derived off-chain. Therefore, users must rely on an oracle to take this data and put it on chain so that the borrower and lender can agree on its value.

The misconception here is that an oracle is useful because it puts data on chain. This is untrue. An oracle is useful because the data it puts on chain is trustworthy. Either the lender or owner could easily upload the price of ETH, the problem is each is incentivized to advantage themself with a better price, so the other will not trust it.

簡單來說，小美是一位司機，而小明是乘客，一開始小美在乘客上車前會先向小告知她的收費方式，這就是第一步，雙以 P2P 的方式確定彼此共識的價格。

達成共識後，就有了一個契約出現，約定了價格，路線，行程並完成付錢，這就是第二步，達成帶著時間戳的契約。

之後，車子就啟動了，因為行進間不能跳車或付完錢不想搭了 ( 這個雖然可以，但會造成乘客損失，通常不會有人做 )，這就確保了乘客繼續履行契約，這就是 POR 如何保障司機的方式。

最後，在規定的時間、地點都到了之後，小明才可以下車，這就是最後一步，雙方完成合約，結束交易。

POR 的好處是完全不用預言機，靠的是用戶 P2P 產生交易並靠著相對應的懲罰及獎勵機制達成買賣雙方最佳利益。但也有缺點，流動性是一大問題，而且當交易途中，貨幣價值的改變，也有可能讓交易無法達到約定價值而無法完成。

小結

Ontropy 將實現集隱私、速度、安全、低費用於一身的項目，讓使用者有更好了使用體驗。現階段還在開發中，但有潛力，值得繼續關注。
