Blockchain has brought a new form of financing to the market. It has the potential to reduce operational complexity and reduce transaction cost by changing business processes. The blockchain combines multiple computer technologies, including distributed data storage, point-to-point transmission, consensus mechanisms and encryption algorithms, with the essence of a distributed database that can autonomously maintain a growing transaction chain. These transaction records are stored in units called blocks, and each block contains a timestamp and a hash link to the previous block so as to prevent tampering.

In the blockchain network, scattered agents or institutions can jointly record and maintain information, and no one agent can exert continuous market power or control. The basic aim of blockchain technology is to decentralize data storage so that such data cannot be controlled or manipulated by central participants. So, after several years of development of the blockchain, ICO emerged in 2017 with the rise of ETH, as did IEO with the upsurge of Binance in 2019, as well as DIDO in 2021.

What are ICO, IEO and DIDO?

ICO (Initial Coin Offering) - Initial coin offering, that is, the use of future products to allow future users to participate in “crowd funding”, a way for users to obtain project profits and dividends by participating in the project's early private placement.

IEO (Initial Exchange Offerings) - Initial exchange offerings is a coin offering mechanism with the exchange as the core. Through the initial exchange offering (IEO), the project is "united" with the exchange, and crowd funding is carried out directly through the exchange. The project coins can help the project enter the market in more efficient ways by means of listing, marketing, and completing smart contracts through the exchange.

DIDO (Decentralized Initial Double Offer) - the decentralized double offer, with a half-price pre-purchase mechanism. After subscription, the users can set the estimated time for doubling the price on their own. If the currency price rises to the target price within the specified time, the users can choose to exercise the right; otherwise the users can choose to get a refund and not to exercise the right.

Comparison between DIDO and ICO & IEO.

Shortly after the emerging of an ICO, only a project introduction is required to complete an ICO financing activity, and similar project products cannot even meet some basic requirements. In addition, the size of the project team is very small, and there is no clear guarantee for the executive capabilities of the team members; they bring about huge risks to investors by financing first and then deploying.

With regards to the legality of ICO, under normal circumstances the overseas supervision departments will include coins in the range of financial products. This means that, in the view of the supervision department, ICO must be transacted according to certain financial regulatory rules. For example, ICO shall also accept the management and supervision of the KYC policy (i.e. Know Your Customer) and public offering regulatory policy. This brings great inconvenience to users.

The advantage of IEO is to avoid restrictions. It can still offer coins when evading the national policy of prohibiting private placement and avoiding ICO link, and the price is uniform at the time of offering. Also, there is no seed round, private placement round, or ICO multi-level price raising.

The exchange has its own users. For the project executor, once an IEO protocol is reached with the exchange, there is no pressure in the listing link, and the lots of publicity costs and energy can be saved in the marketing link due to a large number of basic and loyal users of the exchange itself.

Another advantage is reducing user risks. The exchange acts as a brokerage role, and the project will enter the user's view only after strict investigation and control. For users, the participation in this way can reduce investment risks to a certain extent, increase users' information on the future trend of coins, and increase transaction rates.

However, it is still unavoidable that a small group of people will hold a large number of coins in the early stage of coin offering. There may be interest arbitrage of a small number of major clients, causing investment losses of users, and this is executed in the exchange, which cannot keep confidentiality for users.

Innovation Point of Pre-sale Mode of DIDO

1 If it does not rise after the agreed time, the funds will be returned, with 0 commission.

2 All the purchased funds are injected into decentralization for coin buy-back and destroy.

3 For the open source decentralized smart contract, the smart contract is approved and audited.

First, DIDO is a financing form based on decentralization as the premise. Assets are not collected in the hands of the project executor; however, assets are injected into the LP pool under the premise of taking smart contract as the law, which is a new form of MEME coin offer.

DIDO - Decentralized double offer

Half-price subscription refers to buying tokens at a 50% price, which is equivalent to buying tokens at 50% off.

Half-price subscription refers to the zero cost subscription of the contributing members of the blockchain community. Users can subscribe for a certain amount of coins at half price within the customized planned time, and they can exercise the right to purchase ANB when conditions are met, or choose not to exercise the right and get a refund.

Such community zero-risk subscription plans are for the project financing, and all subscription funds will be contributed to the community, which will be injected into the Uniswap pool, and the repurchased coins will be destroyed at the same time. This mechanism can make the community bigger and allow the community to reach a consensus.

How could users participate in DIDO offering process

For example, user A holds 10,000 USDT and he wants to participate in ANB investment, then he can obtain ANB in two ways: The first is to directly buy from the market on Uniswap, and the second is to subscribe at zero risk. User A applies for subscription of 10,000 USDT on the Angryb platform. The smart contract will deduct 10,000 USDT of the user and include it into the smart contract pool. Assuming that the price of ANB is 0.1 USDT at this time, and the user predicts that the price of ANB will rise to 0.2 USDT in 3 days, but ANB rises to 0.3 USDT the next day, the user can apply for the release of 100,000 ANB. The smart contract releases the ANB, the user obtains the ANB, and can conduct market behaviors by himself. If it does not reach 0.2 USDT, the user can choose to return USDT without any capital loss.

Summary of comparison between DIDO and ICO & IEO.

In a decentralized world, the DIDO financing mechanism has set up a zero-risk mechanism for users, which is certain to be warmly welcomed by the broad market. "Decentralization" is not to remove the center, but to allow the nodes to freely choose the center. ICO & IEO have gradually become products of capital and an individual center. It is very unlikely that ordinary people become "nodes". Angryb aims to set up a new financial system to create a "mechanism for a grassroots counterattack", which makes decisions on the community's own management system and the new financial world through DAO, and is the great revolution of the proletariat and (in?) the new financial world!
