Bitcoin: eCash launches its testnet as the risk of a split remains intact

Bitcoin has just seen a new parallel chain appear. eCash launched its Alpha phase on August 23 at block 963,648. Not yet real ECX for BTC holders: the units currently produced are used for testing. The final hard fork is still scheduled around October 31, at block 973,728. Until then, several technical questions remain open.

Bitcoin sees the first eCash chain appear

The August 23 launch does not yet correspond to the final fork. eCash was already presented as one of the two major bifurcations planned around Bitcoin in 2026. The Alpha phase began at block 963,648. The chain produced its own blocks in parallel with Bitcoin. BTC itself continued to operate normally.

Coins created during this period are called pECX. These are practice units intended to test the network before its official launch. Not yet permanent ECX. The schedule plans a second rehearsal on September 20, around block 967,680. The transition to the Mainnet is then expected around October 31 at block 973,728.

At that time, Bitcoin addresses are expected to receive ECX at a 1-to-1 ratio. The project is led by Paul Sztorc, known for his work on Drivechain and BIP-300 and BIP-301. His idea is not to replace Bitcoin. eCash aims to start from its history then continue with its own rules.

The test has not yet solved all the problems

Alpha at least showed that the new chain could produce blocks. The initial start, however, is not yet a network that is stable. A competing block that became obsolete was notably observed around the activation height.

For a test chain, nothing extraordinary. There is still September to try again. The issue of replay attacks is more relevant for Bitcoin holders. eCash uses address formats close to those of BTC and replay protection does not yet seem to be enforced everywhere.

A transaction broadcast on one chain could therefore, under certain conditions, cause problems on the other if the coins have not been properly separated. Exchanges are already watching the situation. Coincheck indicated it might temporarily suspend BTC deposits and withdrawals around the fork if security requires it. Other platforms have not yet announced whether they will distribute ECX to their clients.

Bitcoin has just come out of another division episode. The fork linked to BIP-110 produced only two blocks during its first eight hours. eCash is trying another method. Alpha first. Beta next. The real fork at the end.

October 31 remains the real date to watch

For BTC holders, nothing has changed yet. Bitcoins remain on Bitcoin. pECX produced today do not yet represent the permanent balance promised at Mainnet.

October 31 should change the situation. From the expected block, eCash wants to take over the state of Bitcoin addresses and credit holders with ECX. Users who keep their keys themselves will theoretically have the means to access coins present on both chains.

For BTC kept on an exchange, it will be different. The platform will control the keys and decide whether it supports the new asset. The project must also convince miners. A chain derived from Bitcoin with little computing power can operate, but it starts with far less security than the main network.

The community already knows the problem. The eCash project had already sparked criticism since its presentation, notably about its technical and economic choices. The Alpha launch does not settle this debate. It simply shows that the rehearsal has begun. September will bring the second. On October 31, eCash will have to play for real.
