Introducing Dahym

World’s First Transient StableCoin – Designed for Digital Spending & Legitimate Consumption

What is Dahym?

Dahym, short for “Dah, Your Money”, rhymes with “dime” and is conveniently valued at 10 cents. It’s a transient stable coin – a temporary currency designed for spending within 6 months. Beyond that, it must be converted to other stablecoin like USDC or USDT.

How Does It Work?

  1. First 3 months: Can only be used at the sponsoring business.
  2. Next 3 months: Usable across any sponsoring business.
  3. After 6 months: Dahyms must be converted to a stablecoin like USDC or USDT

Rollup Ledger

The centralized ledger maintained in Dahyms supports debit, credit, and two unique roll-up unlocks. The first unlock releases Dahyms to all active merchants; the second fully unlocks them for conversion to USDC. Once converted, the Dahyms are removed from the account.

How to Earn Dahyms?

  • Win games (skill or luck based, retro style, with AI elements)
  • Gifted by friends or family
  • Incentive for legitimate licensed digital content consumption

How to Spend Dahyms?

Spend Dahyms at sponsoring businesses within the 6-month period. Merchants receive payment instantly in stablecoins of their choice (USDC, USDT, etc.). Dahyms use cryptographic keys for signing, but not blockchain.

Dahym Gift & Sponsor Cards

  • Gift Cards: Dispatched directly from TVs. No phone or email needed.
  • Sponsor Cards: Businesses sponsor game prizes, giving players spendable Dahyms.

Dahym Kiosk

Minimal kiosk system is now ready for Proof of Concept testing. Contact us to try it out.

Combating Piracy Through Incentives

Dahym fights digital piracy differently — by rewarding legitimate purchases. A portion of digital content purchases funds the stable coin reserve. Dahyms are then credited to the buyer. Live events may earn double incentives via our Legitimate Use API.

Dahym StableCoin
Formula in RollEdge

A credit transaction is recorded in Dhayms. Source of Credit must be gift card or Sponsor card created at Dumbwood Site.This will be recorded as BAL-M1 and BAL-M2 theoretically. M1 stands for Merchant 1 and M2 stands for Merchant 2

.Spendable Balance at M1 = BAL-M1
.Spendable Balance at M2 = BAL-M2

If a customer receives a generic gift card(G). Balance is available to All merchants. BALANCE G Would single balance regardless of the gift cards received.

.Spendable Balance at M1 = BAL-M1 + BAL-M2+BAL-G
.Spendable Balance at M2 = BAL-M1+ BAL-M2+BAL-G
.Spendable Balance at M3 = BAL-M1 + BAL-M2+BAL-M3+BAL-G

The customer did not spend any Dahyms for 3 months. No new Dahyms are received by Customers. Now the customer

.Spendable Balance at M1 = BAL-M1 + BAL-M2
.Spendable Balance at M2 = BAL-M2 + BAL-M1

Now Customer received some Dahyms by winning a game sponsored by Merchant 3. Spendable Balance at M3 = BAL-M1 + BAL-M2 + BAL-M3
After 6 months

.Generic Balance BAL-G = BAL-G + BAL-M1 + BAL-M2

After 9 months

.Generic Balance BAL-G = BAL–G + BAL-M1 + BAL-M2 + BAL-M3

No rollups can happen automatically. It needs to be done by the customer. However
customers will be shown an available rollup balance and an option to roll up. This roll up has
nothing in common with optimistic rollup in the block chain world.

Security of the Rollup Ledger

The account identifier for the Roll up Ledger is public Key. The private key is not stored in the ledger. Any credit or debit needs to be signed by the customer who owns the private key. This makes the ledger secure and makes the ledger publicly accessible.
Since there is a signing requirement for both Credit and debit, automatic credit or debit will not be available to keep the ledger secure.
