chain value.
This planned change is described in EIP-4399It You can also assess the app using on-chain applications. The Merge It occurred. From The EIP:
In Smart Contracts can also be used for verifying if PoS updates happened before the EIP proposals changes. This You You can do this by looking at its return value. DIFFICULTY opcode. A value bigger than 2**64 This This indicates that the transaction is completed in the PoS block.
Block Time
The The Mergers will affect the average block time Ethereum. Current Blocks arrive in 13 seconds on average, as per proof of work. Actual block times can vary broadly. Under ProofIf a validator fails to provide a block or is unavailable, -of–stake blocks are delivered every 12 seconds. In This There are currently only 1% available slots.
This It This means that average block times on the network will decrease by 1 second Smart Contracts This must be taken into consideration by those who use an average block time for their calculations.
Blocks Head Safe, done
Under Reorganizations If there is proof of work, they are always possible. Applications It It is normal to wait several blocks before removing any head from the Canonical Chains. “committed”. After The MergeWe Instead, you can use the concepts Finalized Blocks Secure Head Available In the execution layer These You You can use blocks with greater reliability than “confirmed” You You will need to understand proof-of-work blocks better in order to properly use them.
A completed block is one which has been acknowledged as canonical by more than two thirds of the validators. To An An attacker must stake at most 1/3 of the total amount ether to create a conflicting group. While While Although stake amounts are subject to change, the attacker is likely to lose millions of ETH in an attack like this.
A Secure Head Block This is a type block that has been Justified By Beacon ChainThis This implies that at least 2/3rds of validators have attested it. Under Normal It can be added to the Canonical Chain if it is possible due to network conditions. We You can anticipate it to be finalized eventually. For For To remove this block from the canonical chains, all validators had to agree to attack the network. Or The network would have experienced extreme latency during block propagation. PostThe The -merge APIs (eg JSON RPC) will expose the Secure
