IOB Proof of Enquiries & Trades (PoET)

A blockchain solution to record every price and order enquiry, whether filled or not, and every trade on an immutable distributed public ledger.


An Industry-wide Fair Trading Practice

Through the IOB PoET smart contracts,  every order that occurred on the network is recorded automatically on the distributed public ledger, regardless whether it is filled or not.


Price Spoofing

Spoofing is a disruptive algorithmic trading entity employed by traders to outpace other market participants and to manipulate financial markets.

Proof of All Enquiries

PoET Addresses The Spoofing Problem

Recording all orders sent, not only the small fraction of executed orders. Every time an order is sent, it records its wallet address, time (accurate to a nanosecond), quantity, price, instrument, account/wallet ID, exchange(s) it was sent to.


Front Running

Front-running is the prohibited practice of entering into an order to capitalize on an advance, nonpublic knowledge of a large pending transaction that will influence the price of the underlying security. This is considered a form of market manipulation in many markets.

Proof of All Trades

Every Trade on An Immutable Distributed Public Ledger

PoET records all transactions occurred on the network on an immutable public ledger. Every time an order is executed, it records its wallet address, time (accurate to a nanosecond), quantity, price, instrument, account/wallet ID, and exchange(s).


Fund Transfers and Trade Settlements

Exchanges, broker-dealers, and advisors should not profit from the delayed settlement and clearing of traders’ funds.

The PoET protocol enables an automating instantaneous trading settlement mechanism. The PoET smart contract directly swapped cash and assets from buyers to sellers, resulting in instant settlements.

Giving Back to Traders

The Complete Control of Funds and Assets

Hundreds of millions of dollars worth of cryptocurrencies were hacked through centralized exchanges.  

The PoET protocol enables cryptocurrency trading without the need to trust or rely on a third-party. It uses a hash time-locked contracts (HTLCs) to allow both parties to trade their cryptocurrency directly with each other without having to trust one another or a third party.
