DogecoinIntermediateLitecoin miners commit a Dogecoin block hash in their coinbase, so any Scrypt hash below Dogecoin's easier target counts as AuxPoW. Dogecoin gets Litecoin's hashrate but also shares its pools and risks.

Internet ComputerIntermediateA canister is Wasm code plus heap and stable memory. It pays for compute, messages, storage and HTTPS outcalls in stable-priced cycles made from ICP; below its freezing threshold it freezes, and at zero it's wiped.
#dapp-development#gas-&-fees#smart-contracts
ZcashIntermediateTransparent ZEC works like Bitcoin; shielded Sapling and Orchard notes hide sender, receiver and amount with zk-SNARKs. Stay fully shielded: crossing pools or linking t-addresses leaks amounts and identity.

HederaIntermediateHashgraph has no block producer. Nodes gossip events that record who heard what, then compute the order and median timestamps locally through virtual voting, giving aBFT finality in seconds and fair ordering.

FilecoinIntermediateProviders seal data into sectors, prove it once with PoRep and then daily with WindowPoSt, backed by slashable FIL collateral. Proofs cover storage, not retrieval; use an onramp unless you have large data and DataCap.
#consensus#cryptography#storage
MoneroIntermediateRing signatures (CLSAG, 16 members) hide which output is spent, one-time addresses hide the receiver, and RingCT commitments with Bulletproofs+ hide amounts. Metadata, timing and exchanges still leak.

StarknetIntermediateCairo compiles to Sierra and CASM, uses felt252 plus checked integers, stores state in Map, makes every account a contract, and has no msg.value: ETH and STRK are ERC-20s. Build with Scarb and snforge.

SuiIntermediateMove treats assets as typed resources that can't be copied or dropped, stores state with owners instead of in contract mappings, uses signers and capabilities for access control, and avoids classic reentrancy.

EthereumIntermediateMEV is profit from ordering transactions. A sandwich attack front-runs and back-runs a public swap, capped by its slippage. Use tight minimum outputs from fresh quotes and private RPCs.

EthereumIntermediateApprove is safe; unlimited, forgotten allowances and unread permit signatures are not. Approve exact amounts, use permit with short deadlines, read every typed-data signature, and revoke old approvals.
#security#tokens#wallets
BaseIntermediateERC-4337 makes user accounts smart contracts via UserOperations, bundlers, an EntryPoint and paymasters, enabling batching, gas sponsorship and recovery. EIP-7702 lets existing EOAs delegate to such code.
