Twin Radar
Glossary
New L1 and blockchain words in plain English. Open “Technical detail” for more depth, and follow the links to the official docs.
A
- Account abstraction
- Smarter wallet accounts that can bundle several actions, use limited temporary keys, or have someone else pay the fee.
Technical detail
On New L1 it is native: transaction type 0x76 carries 1 to 64 atomic calls with one signature and nonce, supports delegated session/admin keys with scope, spend limits and expiry, sponsored gas, and secp256k1, P-256 and WebAuthn signatures. No bundler or EntryPoint contract is needed.
- Official docs ↗
- Airdrop
- Free tokens sent to wallets. Fake airdrop sites are one of the most common scams.
Technical detail
Twin Radar does not promise or run any airdrop. Never connect a wallet to a site offering one.
- Async execution
- New L1 agrees on the order of transactions first and runs them just afterwards, so blocks don't wait for heavy computation.
Technical detail
Ordering in slot N carries no execution result; execution completes later and its ExecutionCommitment is published in a later block header. The lag adapts to load, bounded by a governance-set maximum.
- Official docs ↗
B
- BLS signatures
- A type of digital signature where many validator signatures can be combined into one small proof.
Technical detail
New L1 validators sign a block's ordering with BLS; the next proposer aggregates votes from at least two-thirds of validators into an attestation used for fast finality.
- Official docs ↗
- BNB
- BNB Chain's native coin. It pays gas fees and is staked to secure the network.
Technical detail
On New L1, BNB is bridged in from BNB Smart Chain and remains the gas and staking asset. No new token is issued.
- Official docs ↗
- BNB Smart Chain (BSC)
- BNB Chain's established, general-purpose EVM blockchain.
Technical detail
New L1 runs alongside BSC as an additional chain; it does not replace it.
- Official docs ↗
- Bridge (cross-chain bridging)
- A way to move assets from one blockchain to another. Bridges are frequent targets for attacks.
Technical detail
The native BSC to New L1 bridge is in development and not live, according to the official docs.
- Official docs ↗
C
- Contract address
- The unique address of a token or smart contract. Fake tokens copy names, so the address is what you must verify.
Technical detail
No $TWINZ contract exists yet. Any address claiming to be $TWINZ is fake.
D
- Devnet
- An early network for developers. It can be unstable and reset at any time.
Technical detail
New L1 currently runs as a multi-validator devnet. Public testnet and mainnet have not launched.
- Official docs ↗
E
- EVM compatibility
- The chain can run the same smart contracts and tools as Ethereum and BNB Smart Chain.
Technical detail
New L1 keeps EVM execution semantics, so Solidity contracts and tools like Foundry, Hardhat, ethers.js and viem work unchanged; some RPC features differ (for example eth_getProof is unavailable).
- Official docs ↗
F
- Finality
- The moment a transaction can no longer be reversed.
Technical detail
New L1 separates order-finality (two-thirds BLS votes on ordering) from execution-finality (the result committed in a later finalized block). Wait for execution-finality before irreversible actions.
- Official docs ↗
G
- Gas
- The fee paid to have a transaction processed.
Technical detail
On New L1 you are charged for the gas limit you declare, not the gas actually used, and the base fee is zero, so the priority tip sets the price.
- Official docs ↗
- govBNB
- A non-transferable voting token you receive when you stake BNB on New L1.
Technical detail
Minted 1:1 by StakeHub against staked value. It only counts as voting power once delegated to yourself or a validator.
- Official docs ↗
- Governance
- How the network decides on changes: holders of voting power propose and vote.
Technical detail
New L1 uses on-chain Governor and Timelock contracts: proposals target GovHub.updateParam, pass by vote and quorum, wait a mandatory timelock delay, then execute.
- Official docs ↗
L
- Layer 1 (L1)
- A base blockchain that orders and records its own transactions and has its own validators.
Technical detail
New L1 is a new EVM-compatible Layer 1 in the BNB Chain family, designed for latency-sensitive activity.
- Official docs ↗
- LtHash
- The method New L1 uses to fingerprint the whole state of the chain efficiently.
Technical detail
A cumulative lattice-hash accumulator over a flat key-value store; updates cost O(1) per changed entry. Because there is no Merkle trie, eth_getProof and snap sync are unavailable.
- Official docs ↗
M
- Mainnet
- The live network where tokens have real value.
Technical detail
New L1 mainnet has not launched. No launch date is announced in the official docs.
- Official docs ↗
- Mempool
- A waiting room for transactions before they go into a block.
Technical detail
New L1 has no global public mempool; transactions are sent directly to the current and next block producers.
- Official docs ↗
- Multi-Lane
- Reserved space in every block for selected apps, so a rush of unrelated activity can't crowd them out.
Technical detail
Lanes map registered contract addresses to a basis-point share of the block gas limit via the governed LaneRegistry. It guarantees capacity, not inclusion of a specific transaction; ordering within a lane follows fee priority.
- Official docs ↗
P
- Parlia
- The consensus method BNB Chain uses, where staked validators take turns producing blocks.
Technical detail
A proof-of-staked-authority protocol. On New L1 validators rotate every 16 blocks, with up to 64 active validators elected daily by stake.
- Official docs ↗
- Pre-confirmation
- A very fast signal (about 20 ms) that your transaction is being included. It is not final.
Technical detail
A best-effort, validator-signed promise about ordering and inclusion delivered via sub-blocks. It is advisory and revocable, says nothing about execution success, and does not affect consensus or finality.
- Official docs ↗
R
- Rug pull
- When a project's creators take the money and disappear.
S
- Seed phrase
- The 12 or 24 words that control a wallet. Anyone who has them can take everything.
Technical detail
Never type or share it anywhere. Twin Radar and its admins will never ask for it.
- Session key
- A temporary key with limits, so an app can act for you without you approving every step.
Technical detail
On New L1, delegated access keys can be scoped to specific calls, given a spend limit and an expiry.
- Official docs ↗
- Shielded pool
- An opt-in way to make private BNB transfers. Officially not ready for real money yet.
Technical detail
A native system contract using zk-SNARKs (PLONK) for deposit, private transfer and withdrawal of native BNB. Deposits and withdrawals reveal amounts; network metadata is not hidden. The docs state it is unaudited and not production-ready.
- Official docs ↗
- Slashing
- A penalty where a validator loses part of its stake for misbehaving.
Technical detail
Double-sign evidence is submitted on-chain; the SlashIndicator system contract tracks downtime and drives slashing.
- Official docs ↗
- Smart contract
- A program stored on a blockchain that runs automatically when its conditions are met.
- Staking
- Locking coins to help secure a network.
Technical detail
On New L1, BNB is staked through the StakeHub system contract, backing validators and minting govBNB voting power.
- Official docs ↗
- Sub-block
- A small signed piece of a block streamed while the block is still being built.
Technical detail
Sub-blocks carry pre-confirmations; clients can verify them with newl1_subscribeSubBlocks.
- Official docs ↗
T
- Testnet
- A public practice network where tokens have no real value.
Technical detail
New L1's public testnet has not launched.
- Official docs ↗
- Timelock
- A mandatory waiting period between a governance vote passing and the change taking effect.
- Official docs ↗
V
- Validator
- A participant that checks transactions, produces blocks and helps secure the network.
Technical detail
New L1 has up to 64 active validators, elected once a day by stake through StakeHub.
- Official docs ↗
Z
- Zero-knowledge proof
- A way to prove something is true without revealing the details.
