SonicBeginnerSonic is a new EVM chain from the Fantom team: S replaced FTM 1:1, a rewritten client targets higher throughput with aBFT finality, apps can earn up to 90% of their gas fees, and the Sonic Gateway bridges to Ethereum.

Ethereum ClassicBeginnerETC is the original chain that rejected the 2016 DAO-hack fork. It stays proof of work on Etchash, caps supply near 210.7M, uses chain ID 61 and legacy gas pricing, and needs deeper confirmations.

Bitcoin CashBeginnerBCH forked in August 2017 to scale with bigger blocks instead of SegWit. Today it has a 32 MB adaptive limit, native CashTokens, CashAddr addresses, no SegWit or RBF, low fees and far less hashrate than BTC.

ArweaveBeginnerYou pay once into an endowment sized for about 200 years of storage, betting on falling disk costs, and mining requires holding data. Prices move with AR, most uploads go through bundlers, and nothing can be deleted.

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.

LitecoinBeginnerLitecoin is Bitcoin's code with Scrypt proof of work, 2.5-minute blocks and an 84M supply, plus opt-in MWEB privacy and its own address prefixes (L, M, ltc1). Confirmations, fees and libraries need small adjustments.

GeneralBeginnerBitcoin tracks unspent outputs and wallets compute balances, with implicit fees and change outputs. Ethereum stores a balance and nonce per account, so nonce management replaces coin selection.

BitcoinBeginnerMiners hash an 80-byte block header until its double SHA-256 falls below a target. Difficulty retargets every 2016 blocks, and nodes follow the chain with the most cumulative work.
