Transaction

Signed message that changes on‑chain state, such as transfers or contract calls; includes nonce, gas, fee, and payload fields specific to each chain.

Timestamp

Recorded time associated with a block or transaction; may differ slightly from wall‑clock time and is bounded by protocol rules for validity.

Timelock

Mechanism that delays execution of privileged actions for a set period, giving token holders or users time to review and react to governance changes.

Trust‑Minimized Bridge

Cross‑chain bridge that reduces reliance on multisigs or custodians by using light clients, validity proofs, or on‑chain verification for safety.

Trustless

Property of a system where users need not trust a specific party; correct behavior is enforced by cryptography, consensus, and open verification.

Threshold Encryption

Scheme where decryption requires cooperation of at least t of n key shares, enabling secure committees and time‑locked reveals in protocols.

tECDSA, Threshold ECDSA

Threshold variant of ECDSA where multiple participants jointly create signatures compatible with standard ECDSA verification, used in bridges and MPC wallets.

Threshold Signature Scheme (TSS)

Cryptographic method where a signature is produced jointly by multiple parties without reconstructing the private key, improving custody and MPC wallets security.

Tendermint (CometBFT)

Byzantine fault tolerant consensus engine with fast finality used in Cosmos‑style chains; validator set votes in rounds to commit blocks deterministically.

Testnet Faucet

Service that distributes free test tokens to developers and users for deploying contracts and trying apps in non‑production networks.
