Following years of hard work, Ethereum's proof-of-stake upgrade is finally here! The successful upgrade of all public testnets is now complete, and The Merge has been scheduled for the Ethereum mainnet. The Merge is different from previous network upgrades in two ways. First, node operators need to update both their consensus layer (CL) and executi...
Timing
The Merge is a two-step process. The first step is a network upgrade, Bellatrix, on the consensus layer triggered by an epoch height. This is followed by the execution layer's transition from proof-of-work to proof-of-stake, Paris, triggered by a specific Total Difficulty threshold called the Terminal Total Difficulty (TTD). The Bellatrix upgrade is scheduled for epoch 144896 on the Beacon Chain -- 11:34:47am UTC on Sept 6, 2022. Paris, the execution layer's portion of the transition, will be...
Client Releases
The following client releases support The Merge on the Ethereum mainnet. Node operators must run bothan execution and consensus layer client to remain on the network during and after The Merge. When choosing which client to run, validators should be especially mindful of the risks of running a majority client on both the EL and CL. An explainer of these risks and their consequences can be found here. An estimate of current EL and CL client distribution and guides for switching from one client...
Upgrade Specifications
Consensus-critical changes for The Merge are specified in two places: 1. The consensus layer changes under the Bellatrix directoryof the consensus-specs repository 2. The execution layer changes under the Paris specin the execution-specs repository In addition to these, two other specifications cover how the consensus and execution layer clients interact: 1. The Engine API, specified in the execution-apis repository, is used for communication between the consensus and execution layers 2. Opti...
All Merge-related bounties for vulnerabilities have received a 4x multiplier between now and the 8th of September. Critical bugs are now worth up to $1 million USD. See the bug bounty programfor more details.
As a node operator, what should I do?
Post-merge, an Ethereum full node is the combination of a consensus layer (CL) client which runs the proof-of-stake Beacon Chain and an execution layer (EL) client which manages the user-state and runs the computations associated with transactions. The EL and CL client communicate over an authenticated port using a new set of JSON RPC methods called the Engine API. The EL and CL client authenticate each other using a JWT secret. Node operators should refer to their clients' documentation for...
As a staker, what do I need to do?
As explained above, validators on the Beacon Chain will need to run an execution layer client after The Merge in addition to their consensus layer clients.Pre-merge, this was strongly recommended, but some validators have outsourced these functions to third-party providers. This was possible because the only data required on the execution layer were updates to the deposit contract. Post-merge, validators must ensure that user transactions and state transitions blocks that they create and atte...
Why is the estimated date for the Terminal Total Difficulty so broad?
The incremental difficulty added per block is dependent on the network hash rate which is volatile. If more hash rate joins the network, TTD will be reached sooner. Similarly, if hash rate leaves the network, TTD will be reached later. In the event of a significant drop in hash rate levels, a TTD Override could be coordinated as was done on Ropsten.
Ethereum's transition to proof-of-stake has been a loooongtime coming. Thank you to everyone who contributed to researching, specifying, developing, analyzing, testing, breaking, fixing, or explaining everything that got us to The Merge. There have been far too many contributors over the years to list here, but you know who you are. Without all of ...
Aug 25, 2022 · As the Foundation describes, the Merge is a two-step process. The first step is the aforementioned Bellatrix upgrade, due to go live on September 6th at 11:34:47AM UTC.
Sep 6, 2022 · The merge is still expected to happen around Sep 13-15. What's happening today is the Bellatrix hard fork, which *prepares* the chain for the merge.
Aug 12, 2022 · Bellatrix is activated at the chosen epoch. Paris is the Merge transition itself, in which Ethereum Mainnet hot-swaps its consensus from Proof-of-Work to the Beacon Chain's Proof-of-Stake. The Paris upgrade activates at the chosen Terminal Total Difficulty (TTD).
Sep 7, 2022 · Ethereum has successfully launched the Bellatrix Upgrade, an upgrade that marks the beginning of Ethereum’s transition from proof-of-work (PoW) to proof-of-stake (PoS).
