#proof-of-work

Live on-chain data from the Litecoin network (LTC), the long-running silver-to-Bitcoin's-gold proof-of-work UTXO chain with 2.5-minute blocks and Scrypt mining, via the public litecoinspace.org explorer. Like Bitcoin, Litecoin is UTXO-based. Resolve any address's confirmed LTC balance, the total it has ever received and sent, its transaction count and any unconfirmed mempool balance. Look up a transaction's fee, size, input and output counts, total output value and confirmation status. Read a block's height, hash, timestamp, transaction count, size and difficulty. Get the live chain state — the tip height, the recommended fee rates, the mempool size and fees, and the next difficulty adjustment. Live, no key, nothing stored. Distinct from the Bitcoin, Kaspa, XRP Ledger, Cardano, Hedera, Cosmos, Sui, NEAR, MultiversX, Starknet, Solana and EVM on-chain APIs and from price feeds — this is Litecoin's UTXO address state, transactions, blocks and fees. Perfect for wallets, explorers and payments apps.

Live on-chain data from Kaspa (KAS), the fastest proof-of-work Layer 1, via the public api.kaspa.org indexer. Kaspa is not a linear blockchain but a blockDAG running the GHOSTDAG protocol, mined with kHeavyHash at one-or-more blocks per second, so its native state is the UTXO and its native measure of progress is the DAA score. Resolve any address's KAS balance and lifetime transaction count. Pull the unspent outputs an address holds, each with its amount, the transaction that created it, its DAA score and whether it is a coinbase. Read the live blockDAG state — block and header counts, the virtual DAA score, the difficulty, the tip count and pruning point — plus the network hashrate and the circulating-versus-max KAS supply with the share already mined. Look up any transaction with its acceptance status, accepting-block blue score, mass and outputs. Live, no key, nothing stored. Distinct from the XRP Ledger, Stellar, TRON, Aptos, Algorand, Tezos, Cardano, Hedera, Solana and EVM on-chain APIs and from price feeds — this is Kaspa's blockDAG state, UTXO holdings, address balances and transactions. Perfect for wallets, explorers, mining and analytics apps.
