Daily Wager is a cross-chain gambling web application. It allows users to create and promote their own events with their own buy-in amounts, tokens and allow users to choose any sport event (ESPN API) or even enter their own custom event, even creating private events among friends utilizing a password. Event creators can choose to incorporate any ERC-20 approved token (Horizon bridge) or any approved HRC-20 token. Game creators are incentivized to not act maliciously by receiving 1% of their events total pot (validation rankings increase payout), the event creators job is to facilitate the event and promptly settle each event without malintent. After a winner is chosen, there is a dispute period, if a dispute is to arise, the disputer will stake 10% of the pot (preventing abuse) and a centralized authority will settle the dispute (future iteration could be an oracle feed, eliminating the need for event creators to act as settlement). Furthermore, creators are incentivized to tag their events with their Twitter accounts and get validated. Validation means you are a respected creator and entrants are at a lower risk of malintent. Validation rankings increase a validators payout, if they successfully curate 10 events, their payout increases to 2% and so forth. After 100 events successfully curated, they max out at 10% event payouts. One failed dispute and the event creator returns to zero. 8) arabya has started work.

A non-fungible token (NFT) is a special type of cryptographic token that represents something unique. Non-fungible tokens are not mutually interchangeable for a specific monetary amount. CryptoKitties, the popular collectibles on Ethereum, were some of the first non-fungible tokens to gain mass adoption. With the NFTFarm Contract, users can farm non-fungible tokens by staking an ERC20 token. 11) ysongh has started work.

Kawaii Battle Royale (KBR) is a NO-LOSS team-based first-person shooter DeFi Game that runs on the Harmony blockchain and bridges liquidity from Harmony and Ethereum money markets such as AAVE and CREAM Finance.
The game is similar to Overwatch or Fortnite, except that weekly and monthly "interest-bearing ESports no-loss tournaments" are ran, where users stake their entries (BUSD) into a tournament.
The pooled BUSD entries are then transferred from Harmony to the highest-yield earning money market on Ethereum (e.g. AAVE or CREAM) to earn interest. The interest is then used as the tournament's reward - hence the term "no-loss". Once the tournament ends, all staked entries are refunded back to the users.
Further, characters, weapons and skins are tokenized as NFTs and available for trading in our marketplace.

Lending Swap is an application used to swap atoms between tokens, native tokens from Ethereum to Harmony and vice versa.
Between two bridges of Ethereum - Harmony, there are 2 relayers to be able to mint corresponding tokens when swapping between the two platform.
There will be validators at each bridge to verify the atomic swaps, when 75% consensus is reached, the transaction will be executed by the relayer.
In order to be able to transfer the equivalent value of tokens, for example ETH -> ONE, KNC (ERC20) -> WETH (HRC20), we use price data taken from Band Oracle. 18) lyledavids has started work.

LegalAge is a privacy-preserving age-verification service based on zero knowledge cryptography and the HarmonyOne blockchain.
Many people feel uncomfortable to show a passport or an ID-card to strangers, because they can be stalked or their document may be secretly photocopied and their identity stolen. Using the service, anyone can prove that they are older or younger than certain age without presenting an ID or telling the exact date of birth. 20) zyra-zia has started work.

Hack the Horizon
This is going to be an amazing hackathon. Details are below and please check out our main landing page to view the list of AMAZING judges and mentors.
Prize Bounty
A total of $55,000 worth of prizes will be allocated to this hackathon. The breakdown of these prizes to be awarded are the following:
First Prize (5 winners)
Second Prize (7 winners)
Third Prize (10 winners)
Band Protocol Partner Prize
Binance.us Partner Prize
Challenge Description
Priority will go to applications that utilize Horizon, our Harmony-to-Ethereum Bridge. And while we'll consider submissions that don't use our bridge, for this hackathon, we are prioritizing applications that will help build our ecosystem in 3 major categories:
Cross-chain Infrastructure
We are focused on bridging Harmony with other layer 1 blockchains. We are looking for developers to build protocols for cross-chain lending, DEX and additional components for the trustless Horizon bridge.
Cross-chain lending protocols: create a money market lending protocol that allows users to lock assets on Ethereum and access an equivalent value of assets on Harmony, and vice versa. The protocol should be non-custodial and could include an additional mechanism to immediately provide liquidity for assets transferred cross-chain for a fee.
Cross-chain liquidity: build a cross-chain DEX aggregator that allows users to get liquidity and the best prices across different DeFi products including cross-chain DEXes.
Build bots /smart contracts that identify arbitrage opportunities across chains and automatically fulfills orders.
Cross chain staking derivatives: build a protocol for users to stake ONEs on Harmony and receive a derivative token on Ethereum to use in other applications.
Build out components for Harmony’s trustless Horizon bridge including: Provers: a program that provides a proof of user transaction. Relayers: downloads blocks from chains, extracts relevant information and sends it to light client smart contracts. Light clients and verifiers: smart contracts that maintain cross-chain information and verifies the proofs sent by the user.
Build ONE<>BTC (using XCLAIM and BTC-Relay) bridge components: Port BTC-Relay (a stateful SPV client for Bitcoin) as a Harmony smart contract that stores BTC headers and verifies merkle proofs
Implement the ONE-BTC issue and redeem protocols
Vault manager modules for vault register and replace, and treasury smart contract for handling of the ONE-BTC currency (mint, transfer, lock, burn), Collateral module that handles locking, releasing and slashing of collateral & exchange rate manager for getting oracle price
Staked relayers & security module that handles registration and stake of Staked Relayers as well as voting on bridge status changes
Harmony has integrated the Rosetta API. Create a new CLI tool specific to Harmony to view blocks, transactions, sign transactions, deploy contracts view chain information, etc.
DeFi Showcases
We are looking for developers to build and port finance protocols utilizing our Horizon bridge. Bridge liquidity from Ethereum and demonstrate applications that take advantage of Harmony’s fast finality and low fees.
Swoop DEX: fork the Swoop cross-chain DEX and build additional components including a governance token, similar to the UNI token for Uniswap, dashboard info, mobile wallet support and analytic page with all user and pool information/earnings.
DEX ecosystem: build out other features for DEXes including integrating with centralized and decentralized exchanges to bring liquidity, on-chain oracles, and arbitrage bots to mitigate price discrepancies. Also build stop loss protocols to protect liquidity providers against impermanent losses.
On-chain decentralized order book: implement a matching engine as a smart contract on Harmony that also allows users to create limit orders for trading pairs.
Money market lending protocol native on Harmony: build both lending protocols and aggregators with a single interface consolidating lending protocols, including cross-chain protocols, for the best rates. This also could include aggregators for yield farming.
Tokenized synthetic assets: build an issuance protocol to mint and support tokenized synthetic assets using Chainlink and Band oracles and listing the assets on Swoop or other Harmony DEXes.
Build other DeFi showcases including collective savings (PoolTogether, Flavor.finance), decentralized mutual funds (Supertrader), insurance for deposits and smart contract risks (Opyn, Nexus Mutual), prediction markets (Augur, catnip.exchange), decentralized stablecoins (Maker on Harmony).
Build NFT and gaming showcases: build applications that allow users to create, share, sell and buy digital collectibles.
Fiat Utility
Build integrations that would allow fiat currency holders to access ONE and HRC20 tokens and connect ONE to fiat merchants and users.
Fiat loans & lending: build an app for users to deposit Harmony ONE token and receive a fiat (USD, EURO, etc.) loan at a specific collateral ratio.
Remittance and vouchers: allow users to send remittance in the form of cash or gift cards and vouchers across borders to their home countries.
Fiat gateways: build a non-custodial peer-to-peer on/off ramp for ONE tokens and fiat currencies using open banking API for country markets such as India and other countries.
Decentralized currency pegged stablecoins: build a digital currency that keeps a 1:1 peg to the price of that currency with a primary market that buys/sells for the spot rate of 1:1 currency or another mechanism.
Integrations with fiat gateways and merchants: integrate ONE for payments and allow merchants to accept ONE while denominating and settling sales in their national currency.
Investment products: build applications that allow users to invest in a derivative of the equity of any company.
