Deep dives into the 50+ chains Zelcore supports.
Each guide covers what the coin does, how its chain works, how to hold it in Zelcore, and what quirks to watch out for — fees, address formats, memo fields, staking rules.
Celestia is Cosmos tech's biggest win and ATOM's sharpest indictment at once — and now Ethereum's own blobs are squeezing the business it built.
Osmosis, Neutron, and Stride made three different bets on chain sovereignty vs. borrowed security — including one pair that started identically and ended in opposite places.
Cosmos built IBC, the SDK, and Interchain Security to route ecosystem value back to ATOM. The numbers show none of it worked — and 2026's tokenomics rewrite proves it.
IBC replaced trusted bridge signers with light clients and cryptographic proofs, and Eureka just extended that model to Ethereum. How it actually works, and where its trust assumptions still lie.
Cosmos bet that the fix for shared blockchain congestion isn't a bigger chain — it's no shared chain at all. What appchains buy you, what sovereignty costs, and why two big projects left in 2026.
Cardano's 2026 scaling story in two parts: Hydra and Mithril actually work, but the "1 million TPS" number was disowned by Cardano's own technical lead years ago.
Cardano's Midnight chain is live and federated. Its NIGHT/DUST split makes privacy programmable, not anonymous — a serious bet, but early and regulatorily risky.
The real Cardano governance handover happened with Chang and Plomin in 2024-25, not Protocol 11. Here's the actual timeline, the three-body system, and the honest turnout numbers.
The mechanics behind Cardano in 2026: Ouroboros consensus, non-custodial staking, the eUTXO ledger, and ADA's tokenomics — plus an honest look at the 'ghost chain' critique.

A technical guide to the XRP Ledger: federated consensus, 100B pre-mined XRP in escrow, burned transaction fees, and the 1 XRP account reserve.
Tron moved $7.9T in USDT in 2025, rivaling Visa—but its scale rests on two control points: Tether's freeze switch and a founder whose SEC case just closed.
A practical self-custody guide to TRC-20 approvals, fake-USDT airdrops, address poisoning, the Energy trap, and Tron's account-permission takeover vector.
How TRC-20 USDT became the default dollar for remittances and inflation hedging—and why fee economics and network effects keep it dominant.
Understand Tron's DPoS consensus, TRX burn mechanics, and the Energy/Bandwidth resource model that makes USDT transfers near-free at scale.
TON's code is open-source and its validator set is growing — but its economy orbits one private company. How to price that risk before you self-custody.
How Telegram mini apps work on TON, why tap-to-earn tokens collapsed 98%+ after airdrop, and how to stay safe connecting wallets inside your chat app.
Telegram's Wallet hides two services with opposite trust models. Learn which one you're really in, how native USDT on TON works, and how to self-custody it.
TON started as Telegram's Gram project, survived SEC shutdown, and revived as The Open Network. Understand Toncoin, workchains, infinite sharding, and Jettons.

Solana has ~1,414 validators, a Nakamoto coefficient of 19, and ~95% of stake on Agave-lineage code. Here is what Firedancer changes — and what it doesn't.
How Solana fees really work: a flat 5,000-lamport base fee, a priority-fee auction in micro-lamports per CU, and the Jito MEV bundle market.
Proof of History and Tower BFT explained: how Solana uses a SHA-256 VDF and doubling vote lockouts to hit 400ms slots and ~13s rooted finality.
