Bitcoin holders are lined up to receive a matching balance of a new asset called ecash (ECX) when the project kicks off its three-stage hard-fork rollout with an alpha launch around Bitcoin block height 963648.

Key Takeaways

After the failed BIP-110 fork, another hard fork is now barreling toward Bitcoin, this time creating a new crypto asset called ecash (ECX).Paul Sztorc, the developer behind Drivechains and BIP 300/301, crafted the idea.While nearly every BTC holder gets ECX 1:1, a slice of Satoshi’s addresses gets cut out.

ECX Will Leverage a 3-Phase Launch

A beta phase is scheduled around Sept. 20 at Bitcoin block height 967680. That round is expected to lean harder on exchanges, wallet providers, miners, and custodians, the companies that safeguard assets for others.

The proposed technology surfaced in BIP 300 and BIP 301, technical proposals Sztorc developed in 2017 and 2019. BIP 300 lays out a mechanism for moving assets between a main chain and sidechains. BIP 301 describes blind merged mining, which would let miners collect sidechain fees without running all of the software for every sidechain.

ECX plans to launch with seven specialized sidechains, including Thunder for high-throughput payments, Zside for shielded transactions, Bitnames for decentralized identity, Bitassets for token issuance, Photon for quantum-resistant signatures, Truthcoin for prediction markets, and Coinshift for cross-chain trading. The wager is that users can pick features without forcing every bitcoin user to swallow new base-layer rules.

Bitcoin Will Remain Unchanged

The project uses the same SHA-256d mining algorithm as Bitcoin and keeps its base layer close to Bitcoin Core, the dominant Bitcoin software. However, it will run its own network identifier and ports, keeping ECX nodes from mistakenly connecting to Bitcoin. The chain will reset mining difficulty to the minimum at launch before returning to normal adjustments, a setup likely to make early mining conditions fairly volatile.

Self-Custody and Claiming Free Coins The ECX snapshot credits coins straight to bitcoin (BTC) addresses, meaning whoever holds the private keys controls the matching ECX. If BTC sits on an exchange, the exchange holds those keys and effectively controls the forked ECX, leaving customers at its mercy for distribution. Self-custody cuts out that middleman, putting the keys in the holder’s hands and giving them direct control over the corresponding ECX. Image source: ecash.com.

The real fight starts after Oct. 31. ECX will need working sidechains, stable software, willing exchanges and enough miner participation to show that its combined fee model actually works. Bitcoin holders seeking direct access should track the snapshot heights, maintain control of their keys and stick with official guidance. They should also remember that ECX has nothing to do with XEC, the separate cryptocurrency that uses the same ecash name.
