Zcash Ironwood hard fork seals Orchard pool July 28 after 4-year bug
Zcash will activate the Ironwood hard fork on July 28 at block 3,428,143, sealing the Orchard shielded pool after a soundness bug that went undetected for four years. "The turnstile mechanism ensures the supply of ZEC is mathematically and publicly verifiable by anyone running node software," Zooko Wilcox, co-founder and lead developer of Zcash, said. The bug, discovered May 29 by Shielded Labs researcher Taylor Hornby, had been live since Orchard activated in May 2022. Developers patched the vulnerability via the NU6.2 hard fork on June 3, but zero-knowledge proofs leave no on-chain record of past transactions, making it impossible to confirm whether counterfeit ZEC was ever minted. Ironwood's turnstile caps withdrawals from the old pool at the total amount of legitimate deposits, trapping any forged coins inside permanently. Node operators, exchanges and wallet providers must upgrade before the activation block or risk falling off the canonical chain. The upgrade arrives alongside Zakura, a new full node from Zcash founding cryptographer Sean Bowe and Osmosis co-founder Dev Ojha, which achieves a four-hour sync time through pruning and snapshot support. The turnstile is not new to Zcash — the network used a similar mechanism during earlier pool migrations — but applying it to Orchard marks a more aggressive containment step. The old pool will accept no new deposits after the fork. Funds can only exit through the turnstile gateway, which enforces a strict balance check: only the total amount of ZEC that provably entered the pool over its lifetime can leave. Any excess, whether from the bug or otherwise, stays locked. Zakura, released July 16 at version 1.0.0, is maintained independently of the Zcash Foundation. It is a pruned fork of the Foundation's Zebra node software and includes a compatibility mode that reproduces the interface of the legacy zcashd client, which reached end of life on July 18. The team behind Zakura — funded by private ZEC donations rather than a foundation or company — has broader ambitions: matching Visa- and Mastercard-level throughput of more than 50,000 transactions per second through recursive proofs under Project Tachyon and private information retrieval techniques from Valar Group. For now, the immediate test is the July 28 activation. Exchanges and wallet providers that support ZEC have been given additional preparation time after the activation was pushed back one week from the original target. Users managing ZEC through private wallets may see their Orchard balances temporarily appear unavailable as nodes process the transition between the old and new pools.

Stablecoin supply hits $310B as Armstrong says Bitcoin missed Satoshi's goal
**Coinbase CEO Brian Armstrong said Bitcoin failed to become the peer-to-peer cash Satoshi Nakamoto envisioned, with stablecoins capturing the payments use case instead.** Bitcoin trades at $64,523, down 45% from its October 2025 peak of $126,080, as stablecoin supply hit a record $310 billion. "It's fair to say at this point that Bitcoin has succeeded as a store of value, and I don't think it has become a medium of exchange," Brian Armstrong, chief executive officer of Coinbase, said in an interview with Zerodha co-founder Nikhil Kamath on the People by WTF podcast. Nakamoto's 2008 whitepaper envisioned electronic cash moving directly between parties without a bank. Seventeen years later, Bitcoin's capped supply and volatility have encouraged hoarding rather than spending, Armstrong said. "People think it's going to be worth more in the future, so they don't really want to spend it right now," he added. Attempts to fix this, such as the Lightning Network, "never really took off." Meanwhile, stablecoins filled the gap. DefiLlama data shows total stablecoin supply near $310 billion, with Tether's USDT at $184 billion and Circle's USDC at $73 billion. Much of that activity now runs on Coinbase's Base and Solana, Armstrong said, crediting the GENIUS Act signed in July 2025 for giving the tokens legal clarity in the US. The divergence carries implications for capital allocation across crypto markets. With Bitcoin cemented as digital gold and stablecoins processing an increasing share of on-chain payments, investors face a structural choice between the two use cases — one that Armstrong said the Bitcoin chain itself has accepted. "They're not intending it to be used for high volume payments," he said. "They're digital gold." The shift also raises questions about Bitcoin's long-term value proposition relative to other networks. If stablecoins have captured the payments use case that anchored Bitcoin's original thesis, the primary remaining driver for BTC demand is its store-of-value narrative — a role that depends on continued institutional adoption and macro uncertainty. Bitcoin's market dominance has fluctuated as capital rotates between BTC, ETH, and stablecoin-denominated DeFi yields, with no clear trend emerging.

Bitcoin whales add 66,700 BTC as mid-sized holders sell into strength
**Bitcoin's largest wallets absorbed 66,700 coins last week while mid-tier holders shed 77,800, on-chain data shows.** Bitcoin whales accumulated 66,700 BTC as mid-sized holders sold 77,800 coins, on-chain data showed July 19, deepening a supply shift toward large investors. The divergence between wallet cohorts was identified by on-chain analytics firm CryptoQuant, which tracks Bitcoin supply distribution across address sizes. Whale addresses — those holding at least 1,000 BTC — have added to positions for three consecutive weeks, while wallets with 10 to 1,000 BTC have reduced holdings. The 66,700 BTC accumulated by whales represents roughly $4.3 billion at prevailing market prices. The mid-holder sell-off of 77,800 BTC amounts to approximately $5 billion in notional value. The redistribution comes as several long-dormant wallets have reactivated in recent days, drawing attention to the movement of older coins. The supply shift toward larger holders historically precedes sustained price appreciation, as whale-class investors tend to hold through market cycles rather than trade actively. With Bitcoin's supply cap fixed at 21 million coins, the net absorption by large wallets reduces the circulating supply available on exchanges — a dynamic that has supported price gains in prior cycles. ## Whale Activity Picks Up Amid Dormant Wallet Reactivations The accumulation by large holders coincides with a wave of dormant wallet movements that have drawn market scrutiny. A wallet linked to the "Noah Doe" litigation — an anonymous plaintiff seeking ownership of roughly 3.8 million dormant Bitcoin — moved 5,907 BTC to a new address on July 16, Galaxy Research said. The coins, originally received when Bitcoin traded near $17,000 in December 2017, had appreciated 291%. On July 12, a separate wallet transferred 2,931 BTC after seven years and nine months of inactivity. The sending address had last moved funds in October 2018 when Bitcoin traded at $6,475, according to Onchain Lens and Arkham Intelligence. Neither transfer went to a known exchange deposit address, suggesting the holders were reorganizing wallets rather than preparing to sell. ## Supply Dynamics Favor Long-Term Holders The net absorption of coins by whale addresses mirrors a pattern that CryptoQuant analyst J.A. Maartun described in December as a "great redistribution," during which Bitcoin held by long-term holders transfers to new owners in waves. Mid-sized holders — often categorized as retail and smaller institutional participants — have been net distributors during the same period, selling 77,800 BTC. Institutional "new whales" now control roughly $130 billion worth of Bitcoin, surpassing the approximately $126 billion held by long-term whales, according to CryptoQuant data from earlier this year. The continued accumulation by large wallets suggests institutional demand remains strong even as smaller participants take profits.
