Stablecoins and the dollar — dollars on the blockchain

Dollars on the blockchain

A stablecoin is a token designed not to fluctuate. The commonest kind is the dollar stablecoin: one token worth one dollar because the issuer holds the same amount of dollars in reserve. Tether (USDT) and USDC are the best known. In the Mobick ecosystem, Harvest MOVN paper wallets and Crypto Literacy fees can be paid in USDT or USDC.

FIG. 1The general structure of a dollar stablecoin. Reserves back the coins 1:1, and since reserves are held in Treasuries, more coins mean more Treasury demand.

Reserves are usually cash and short-term US Treasuries. The more stablecoins are used, the more Treasuries issuers must buy. In 2025 the US passed its stablecoin law (the GENIUS Act), setting rules such as full reserves, regular audits and redemption rights. The Mobick blog describes New Frontier Labs’ FYUSD — Mobick’s April 2026 partner — as following that law, issued and held in custody by a US bank trust.

How Oh Taemin reads it

This part is interpretation, summarising Oh Taemin’s view:

A new container for the dollar — on 4 October 2025 he argued that influential circles in the US see dollar stablecoins as a way to ease the Treasury problem and extend the dollar’s reach, since stablecoins create demand for Treasuries.
Blocking only makes it bigger — in April 2026 he said that even if Korea blocks foreign apps and tightens rules, people will end up trading tokenised shares through US apps, and stablecoins will come back in through DeFi. His 3 October 2026 stream was titled “The more they block it, the bigger crypto gets.”
In books — these ideas run through his 2026 books on the dollar problem, the dollar paradox and the end of finance.

Where Mobick fits

Mobick does not mint a dollar stablecoin itself, but sits alongside the trend:

What	Nature
MOVN	BMB-backed, aims at $1, does not insist on a 1:1 peg; swaps with USDT on Uniswap
New Frontier Labs partnership	Strategic partnership with the maker of the FYUSD dollar stablecoin and payment rails (details to follow)
Mobick halls	Pictured on 19 September as emergency hubs where even dollar stablecoins change hands person to person

Summary

Dollar stablecoins are blockchain dollars backed 1:1 by reserves (cash, short Treasuries).
The US set rules with the 2025 GENIUS Act, and stablecoins link to Treasury demand.
Oh sees them as a new container for dollar influence that blocking cannot stop (interpretation).
Mobick sits alongside via MOVN (BMB-backed, aims at $1) and the FYUSD partnership.
