đ What are miners & validators in crypto?
Miners, validators, confirmations, nodes, what does it all mean in crypto and how does it all come together on-chain?

â
For a long time, the story sounded like a single-chain showdown. But once you look at on-chain stablecoin data, itâs obvious that âon-chain dollarsâ donât pick one winner â they spread across networks based on the job being done.
The cleanest way to see that split is to look at where stablecoins are issued and circulating by chain (a useful proxy for âwhere dollars live,â even though itâs not the same as transfer volume).
â
Ethereum holds the largest share of both USDT and USDC supply in your snapshot. That matches its role as the chain with the most entrenched liquidity, integrations, and credibility for higher-value flows â the place where stablecoins often anchor even if activity happens elsewhere.
â
Tronâs dominance is very specific: itâs a USDT superhighway. The chainâs economics (very low fees) make it ideal for high-frequency transfers and payment-like usage, which is exactly where USDT is strongest.
â
Solanaâs stablecoin profile is more aligned with USDC-heavy app liquidity. The network is optimized for rapid trading loops, frequent interactions, and consumer-grade throughput â which fits USDCâs role as a widely used base asset inside fast-moving on-chain economies.
â
TONâs USDT presence is still small next to Ethereum/Tron, but itâs meaningful because the use case is different: consumer distribution. TON is less about being the main settlement layer and more about making stablecoins usable inside messaging, via Telegram-native flows.

â
If you step back, the data supports a simple market structure:
â
Stablecoins arenât just âon Ethereumâ or âon Solana.â Theyâre turning blockchains into financial infrastructure layers, with different networks acting like different parts of the same system: settlement, liquidity, payments, distribution.
â
Stablecoins arenât a âmarketâ anymore, theyâre the operating system: deposits, withdrawals, quotes, payments, and settlement all run on them. The dollars have gone on-chain. For operators, it is critical to get the future dollar system integrated into their business. This means all the optionality, backend control and complicated UX under one fintech and payment service.
