1. eCash Uses a Hybrid Model

eCash is not a fully PoS blockchain like Avalanche or Aptos.

Instead, it combines:

a Proof-of-Work (PoW) base layer similar to Bitcoin
with an additional Avalanche Pre-Consensus layer for fast confirmations.

The process looks like this:

User sends XEC
        ↓
Avalanche Pre-Consensus confirms (~2–3 seconds)
        ↓
Transaction becomes nearly locked/finalized
        ↓
PoW miners include it in a block
        ↓
Block is mined (~10 minutes average)
        ↓
Traditional PoW finality achieved

2. What Is Avalanche Pre-Consensus?

This is eCash’s fast confirmation layer.

When a transaction is broadcast:

Avalanche nodes vote on the transaction
if enough nodes agree,
the transaction is considered “locked” almost instantly

This usually takes only a few seconds.

As a result:

users get fast transaction confidence
double-spend risks are greatly reduced
the experience feels similar to modern high-speed blockchains

This is why the eCash community often says:

“XEC has instant finality in 2–3 seconds.”

3. So Why Does Chainspect Still Show 10 Minutes?

Because websites like Chainspect usually measure:

the finality of the actual blockchain block
meaning the moment the PoW block is successfully mined

Since eCash still uses:

a PoW structure
with an average block time of around 10 minutes

these sites display:

SystemDisplayed FinalityAvalanche layer~2–3 secondsPoW block finality~10 minutes

4. Why Doesn’t eCash Remove PoW Completely?

The goal of eCash is to combine:

Bitcoin-level security
with modern fast transaction speeds

If eCash used only Avalanche:

transactions would be faster
but it would lose traditional PoW characteristics

If it used only PoW:

payments would feel too slow for real-world usage

So eCash combines both:

5. Can Transactions Still Be Reversed After Avalanche Confirmation?

In theory, yes.

If there were:

an extreme attack,
a major software bug,
or a very large chain reorganization,

a transaction could still potentially be reversed.

However, an attacker would need to:

overcome the Avalanche consensus layer,
and also control enough PoW power

This makes attacks significantly harder compared to a standard PoW chain.

6. Simple Conclusion

Today, eCash provides:

fast confirmations within seconds using Avalanche Pre-Consensus
while still maintaining traditional PoW finality of around 10 minutes

In simple terms:

Avalanche provides fast confirmation.
PoW provides long-term security.

That’s why:

the eCash community describes XEC as extremely fast,
while blockchain statistic sites still display a 10-minute finality.

Why does eCash claim transactions confirm in 2–3 seconds, while Chainspect shows a 10-minute finalit
