Blockchain Networks Explained (In Plain English)
If you’ve ever tried to send USDT or another token and saw options like ERC-20, TRC-20, or BEP-20, you’ve already learned a key lesson: when you send crypto, you don’t choose only the asset — you also choose the network.
What is a blockchain network (and why it matters)
Think of a blockchain network as the route your transaction takes. The network you pick determines:
- Fees (how much you pay to send)
- Speed (how quickly you get confirmations)
- Reliability (congestion can cause delays)
- Compatibility (whether the receiving address supports that network)
Crucially, a token and a network are not the same thing. For example, USDT exists on multiple networks. If you send USDT via the wrong network to an address that doesn’t support it, funds may not arrive or may require complex recovery.
Why there are hundreds of networks, but people use only a few
Many blockchains exist, but most everyday activity concentrates in a small number of ecosystems. Different networks optimize for different goals:
- DeFi and finance: liquidity, security, and a strong app ecosystem
- NFTs and gaming: throughput and user-friendly transactions
- Meme tokens: fast launches and low friction
- Payments and transfers: predictable fees and fast settlement
That’s why the same asset can be available across multiple networks — and you choose based on what you need: pay more for a familiar route, or send faster and cheaper.
ERC-20 vs TRC-20 vs BEP-20: what’s the difference?
People often call these “networks,” but they’re token standards within specific blockchains (Ethereum, Tron, BNB Smart Chain). In real user interfaces, they function like network choices.
- ERC-20 (Ethereum): widely supported, huge DeFi ecosystem; fees can be higher during congestion
- TRC-20 (Tron): commonly used for USDT transfers; often low fees and fast confirmations
- BEP-20 (BNB Smart Chain): low fees and many apps; always confirm address/network compatibility
Practical rule: the “withdrawal network” on the sender must match the “deposit network” on the receiver. That single check prevents most losses.
How to choose the best network for sending USDT (or BTC)
- Confirm which networks the receiving wallet/exchange supports
- Match the selected network on both sides (don’t rely only on address format)
- Compare fees and expected confirmation times
- For large transfers, send a small test transaction first
- Save the TxID and verify status in a block explorer
How it works in OneSix
In OneSix, you choose both the token and the network when sending crypto. Right now, OneSix supports the TRC-20 network — one of the most popular options for USDT transfers thanks to low fees, fast settlement, and a straightforward user experience.
We started with TRC-20 intentionally because it covers a major real-world use case. More networks are in progress, and we’ll add options for different scenarios over time.
What if you need to move tokens between networks?
If you need to move an asset from one network to another, you typically use a bridge (cross-chain bridge). Bridges help you swap or reissue assets across networks.
Note: bridges add extra risk (phishing, wrong network selection, extra fees, delays). Use reputable providers and always verify the domain and transaction details before confirming.
