A unique identifier on a blockchain — like a bank account number. On TRON (TRC20), addresses begin with “T” and are 34 characters. Derived from a public key and safe to share publicly to receive tokens.

A container holding a batch of validated transactions. Each block includes a cryptographic hash of the previous block, forming the chain. TRON produces a new block approximately every 3 seconds.

A distributed, append-only ledger where data is stored in cryptographically linked blocks. Once confirmed, data cannot be altered without invalidating all subsequent blocks — providing immutability and transparency.

The count of blocks added after the block containing your transaction. More confirmations = greater finality. 20+ confirmations on TRON is considered highly secure and practically irreversible.

The protocol by which distributed nodes agree on the valid blockchain state. TRON uses Delegated Proof of Stake (DPoS), with 27 elected Super Representatives producing and validating blocks.

Self-executing code deployed on a blockchain that enforces its rules automatically when conditions are met. TRC20 tokens — including USDT on TRON — are governed by smart contracts defining supply and transfers.

The computational fee required to execute a transaction. On TRON this is “Energy” and “Bandwidth.” Insufficient energy causes a transaction to fail. In the private FC Network, gas mechanics may differ from the public chain.

A fixed-length string produced by a cryptographic hash function. A TXID is a unique fingerprint for each transaction — 64 hexadecimal characters on TRON. A valid TXID can be verified on Tronscan to confirm on-chain existence. FC Network transaction hashes return “Not Found” on public explorers.

A record-keeping system tracking balances and transactions. A blockchain is a distributed ledger — copies exist across thousands of nodes simultaneously, making fraudulent alteration computationally infeasible.

Short for “memory pool.” A temporary holding area where unconfirmed transactions wait before validators include them in the next block. High congestion increases fees and delays confirmation times.

A computer participating in a blockchain network by storing a ledger copy and relaying transactions. Full nodes validate every transaction against consensus rules. TRON has thousands of nodes worldwide.

A secret 256-bit number proving wallet ownership and authorizing transactions. Anyone with your private key controls your funds completely. Never share your private key — there is no legitimate reason for any third party to request it.

Derived mathematically from your private key and used to generate your wallet address. Safe to share. The derivation is one-way — you cannot reverse a public key to obtain the private key.

A human-readable wallet backup — typically 12 or 24 words in a specific order. Anyone with your seed phrase can restore your wallet and access all funds. Store offline only. Never share it digitally.

A digital asset created on top of an existing blockchain (not a native coin). TRC20 tokens run on TRON. USDT on TRON is a TRC20 token. Tokens inherit chain security but are governed by their own smart contract.

A signed instruction to transfer tokens or execute a smart contract function. Every transaction is broadcast, validated, and permanently recorded in a block. Transactions are irreversible once confirmed.

The technical standard for tokens on the TRON blockchain, analogous to Ethereum’s ERC20. TRC20 defines compatibility rules across wallets and exchanges. USDT (Tether) on TRON is a TRC20 token.

Software or hardware that stores your private keys and lets you manage blockchain assets. A wallet does not “hold” tokens — tokens live on the blockchain. The wallet provides the keys to authorize transactions from your address.
