Oracle Integration

What is an Oracle?

In blockchain, an oracle is a system that brings real-world data onto the blockchain. Smart contracts can't access the internet, so oracles act as bridges.

Why Oracles Matter

For Hivebets to resolve markets automatically, we need to know:

• What is the current market cap of token X?

• Did token X reach the target by the deadline?

This data exists off-chain (on exchanges, DEXs, aggregators). An oracle fetches it and makes it available on-chain.

Hivebets Oracle

Hivebets uses its own advanced decentralized oracle network on BSC Mainnet.

Key Features:

Decentralized - Multiple data reporters Transparent - All data on-chain Dispute Mechanism - False data can be challenged Trustless - No central authority

Cryptoeconomically Secure - Staking and slashing

How Markets Resolve

Automatic Resolution Flow

1. Market Deadline Passes
   ↓
2. 1-Hour Buffer Period
   ↓
3. Anyone Calls resolveFromHivebets()
   ↓
4. Contract Queries Hivebets Oracle
   ↓
5. Hivebets Returns Market Cap Data
   ↓
6. Contract Compares to Target
   ↓
7. Market Resolves to YES or NO
   ↓
8. Winners Can Claim Payouts

Step-by-Step Breakdown

1. Deadline Passes

Example: Market deadline is Oct 31, 2025 23:59:59 UTC
No more bets allowed after this time.

2. Buffer Period (1 Hour)

Between deadline and resolution:
- Ensures oracle data is available
- Prevents frontrunning
- Gives reporters time to submit data

Anyone trying to resolve before buffer ends will fail.

3. Resolution Trigger

// Anyone can call this function (no special permissions)
function resolveFromHivebets() external {
    require(block.timestamp >= deadline + 1 hour);
    // ... resolution logic
}

Anyone can trigger resolution:

• User

• Developer

• Bot

• Random person

No gas cost for Hivebets - caller pays gas.

4. Query HIvebets

// Contract asks Hivebets: "What's the market cap?"
(bytes memory value, uint timestamp) = Hivebets.getDataBefore(
    queryId, 
    deadline + 1 hour
);

queryId uniquely identifies the data request:

• Token address

• Data type (MarketCap)

5. Hivebets Returns Data

// Hivebets returns:
uint256 marketCap = abi.decode(value, (uint256));

// Example: 125000000 (= $125M in 8 decimals)

6. Compare to Target

if (marketCap >= targetMarketCap) {
    outcome = true; // YES wins
} else {
    outcome = false; // NO wins
}

7. Market Resolved

resolved = true;
emit Resolved(outcome);

Once resolved, cannot be changed. Result is final.

8. Claims Open

function claim() external {
    require(resolved, "Not resolved");
    // ... payout logic
}

Winners can now claim their BNB.

---

Fallback: Manual Resolution

If Hivebets data is unavailable or disputed, the resolver (contract creator) can manually resolve:

function resolveManual(bool _outcome) external onlyResolver {
    require(!resolved, "Already resolved");
    require(block.timestamp >= deadline, "Before deadline");
    
    resolved = true;
    outcome = _outcome;
    
    emit Resolved(outcome);
}

When Manual Resolution is Used:

• Hivebets data not available

• Hivebets data is disputed

• Oracle network issues

Requirements:

• Only the designated resolver can call

• Must provide verifiable proof (e.g., DEXScreener screenshot)

• Community can verify on BSCScan

Example: 哈基米 Market

Let's walk through a real resolution:

Market Setup

Token: 哈基米
Question: Will 哈基米 reach $100M mcap before Oct 30?
Target: $100,000,000
Deadline: Oct 30, 2025 23:59:59 UTC
QueryId: 0xabc123... (for "TokenMarketCap" of 哈基米)

Timeline

October 25, 2025

Current market cap: $75M
YES Pool: 5 BNB
NO Pool: 3 BNB
Betting still open.

October 30, 2025 20:00 UTC

Market cap pumps to $110M!
YES Pool: 8 BNB (final)
NO Pool: 4 BNB (final)
Deadline in 4 hours.

October 30, 2025 23:59:59 UTC

Deadline hits!
No more bets allowed.
Market cap: $115M

October 31, 2025 01:00 UTC

Buffer period ends (1 hour after deadline).
Anyone can now call resolveFromHivebets().

October 31, 2025 01:05 UTC

Bob calls resolveFromHivebets():
1. Function queries Hivebets
2. Hivebets returns: market cap = $115M at Oct 30 23:59
3. Contract checks: $115M >= $100M? YES ✅
4. Market resolves to YES
5. Event emitted: Resolved(true)

October 31, 2025 01:10 UTC

YES bettors see "Claim Winnings" button.
Alice clicks, confirms transaction, receives her payout!

Data Query Specification

Query Structure

// Encode query parameters
bytes queryData = abi.encode(
    "TokenMarketCap",  // Data type
    tokenAddress       // Which token (e.g., 哈基米)
);

// Generate unique query ID
bytes32 queryId = keccak256(queryData);

Data Format

Hivebets returns market cap as uint256 with 8 decimals:

$1 = 100000000
$100M = 10000000000000000
$1B = 100000000000000000

Example:

Real market cap: $125,500,000
Hivebets value: 12550000000000000

---

Security Features

1. Dispute Mechanism

If Hivebets data is incorrect:

• Anyone can dispute within 12 hours

• Disputer stakes TRB

• If successful, bad reporter is slashed

• Hivebets can wait for dispute period

2. Time-Weighted Average

Hivebets can provide TWAP (Time-Weighted Average Price) to prevent manipulation via flash loans or brief pumps.

3. Multiple Reporters

Multiple independent parties report data, increasing reliability.

4. Cryptoeconomic Security

Reporters stake TRB tokens. Bad data = loss of stake.

---

What If Scenarios

What if Hivebets data doesn't exist?

Answer: Resolver manually resolves using verifiable data (DEXScreener, etc.). Community can verify on BSCScan.

What if Hivebets data is disputed?

Answer: Wait for dispute resolution. If dispute succeeds, use corrected data. If needed, resolver manually resolves.

What if resolver manually resolves incorrectly?

Answer: All data is on-chain. Anyone can verify. Reputation damage would hurt future markets. Future versions could use DAO voting.

What if there's a flash crash right at deadline?

Answer: Hivebets can use time-weighted average or median price over a period to prevent manipulation.

What if nobody triggers resolveFromHivebets()?

Answer: Eventually someone will (to claim their winnings). Anyone can call it. We can also run a bot.

Comparison to Alternatives

Oracle Type	Pros	Cons	Hivebets Choice
Hivebets	Decentralized, proven, on BSC	Requires reporters	Primary
Chainlink	Most established	Not specialized for custom data	Not used
Manual Only	Simple	Requires trust	Fallback only
Snapshot Oracle	Free	Centralized	Not used

---

Future Enhancements

Potential improvements to oracle resolution:

1. Multi-Oracle

Query both Hivebets + Chainlink. Resolve only if both agree.

2. DAO Resolution

If oracles disagree, token holders vote on outcome.

3. Dispute Period

Mandatory 12-hour wait before finalization, allowing disputes.

4. TWAP by Default

Always use time-weighted average over last hour.

---

Transparency

All oracle interactions are publicly visible on BSCScan:

• Query submission

• Data returned

• Timestamp of data

• Resolution transaction

• Outcome

Anyone can verify:

1. Check BSCScan for market contract
2. Find Resolved event
3. See exact oracle data used
4. Verify correctness against DEXScreener/CoinGecko
