eth/65: transaction announcements and retrievals
EIP 2464. Péter Szilágyi , Péter Szilágyi , Gary Rong , Tim Beiko.
EIP 2464, eth/65: transaction announcements and retrievals. Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transaction request.
Status in the source: Final. A reading of the public specification, not a copy of it and not a certification.
eth/65: transaction announcements and retrievals is worth reading for the rule it actually adds: Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transact...

01 Claim ledger
What the paper is allowed to say
Each row is a sentence already in the study. The status is the same on every row: a model claim, not a live measurement.
Claim 01 · Paper model
The rule
Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transaction request.
Claim 02 · Paper model
What was already failing
A node that cannot fetch, filter, or relay the data it is supposed to validate is not a peer of the network the paper describes.
Claim 03 · Paper model
What the number does not mean
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
Claim 04 · Paper model
What a builder should be able to point at
An implementation either constrains eth/65: transaction announcements and retrievals or it is a different design.
02 Three cuts
Observation, model, falsifier
A desk does not stop at the summary. Each claim is cut three ways, using only this study's own assumptions and checks. Nothing here is a new figure.
01 The rule
Observation
What the study says
Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transaction request.
Model
What has to hold
The object that has to change is eth/65: transaction announcements and retrievals. A neighbouring document with a similar name is not this one.
Falsifier
What would retire it
Which message does eth/65: transaction announcements and retrievals add, and which old peer must still be answered?
02 What was already failing
Observation
What the study says
A node that cannot fetch, filter, or relay the data it is supposed to validate is not a peer of the network the paper describes.
Model
What has to hold
The object that has to change is eth/65: transaction announcements and retrievals. A neighbouring document with a similar name is not this one.
Falsifier
What would retire it
What does a node do when the short form fails and the full object is required?
03 What the number does not mean
Observation
What the study says
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
Model
What has to hold
You are implementing EIP 2464 at the status the text itself states: Final.
Falsifier
What would retire it
Which names are normative: eth/65: transaction announcements and retrievals?
04 What a builder should be able to point at

Which message does eth/65: transaction announcements and retrievals add, and which old peer must still be answered?
03 Sequence
One action, as an operating tape
- 01Open EIP 2464 and read the status line before the examples.
- 02Write down the rule in one sentence. A fair version of that sentence is: Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transaction request.
- 03Name the object that changes: eth/65: transaction announcements and retrievals.
- 04Ask what an old client, an old contract, or an offline counterparty does. If the document is silent, the silence is part of the design.
04 Load-bearing
The argument, and where a pitch drops it
What the text is allowed to settle
The cut
Ethereum Improvement Proposal 2464 can settle the shape of eth/65: transaction announcements and retrievals. It cannot settle whether a later client, a later fork, or a later wallet still does this.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
A peer protocol is not a consensus rule. A peer can disconnect. A block is still valid or not on its own.
What this page will not pretend
The cut
There is no benchmark, no adoption number, and no claim that the mechanism is safe outside the assumptions written in the source.
Why it carries weight
If this cut is skipped, the paper's name is being used without the mechanism that makes the name mean anything.
Where it is dropped
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it.
05 Register
What has to be true
Model · Not re-measured
You are implementing EIP 2464 at the status the text itself states: Final.
Model · Not re-measured
The object that has to change is eth/65: transaction announcements and retrievals. A neighbouring document with a similar name is not this one.
Network · Not re-measured
Measurements of delay in one year do not travel with the specification.
06 Divergence
What happened after the paper
The source marks this final. That is a statement about the text, not a promise that every wallet or node has shipped it. Later documents can narrow, replace, or ignore this one. Cite the number you mean.
A later client, parameter set, or reward formula is a different object. Cite this paper for the mechanism. Cite a primary release for the network. This desk has not re-run the proof.

08 Anatomy
The paper, in the order a builder needs
The problem it names
A node that cannot fetch, filter, or relay the data it is supposed to validate is not a peer of the network the paper describes.
What the design proposes
- Three additional message types into the eth protocol (releasing a new version, eth/65): NewPooledTransactionHashes (0x08) to announce a set of transactions without their content; GetPooledTransactions (0x09) to request a batch of transactions by their announced hash; and PooledTransactions (0x0a) to reply to a transaction request.
- This permits reducing the bandwidth used for transaction propagation from linear complexity in the number of peers to square root; and also reducing the initial transaction exchange from 10s-100s MB to len(pool) 32B ~= 128KB.
- The eth network protocol has two ways to propagate a newly mined block: it can be broadcast to a peer in its entirety (via NewBlock (0x07) in eth/64 and prior or it can be announced only (via NewBlockHashes (0x01)).
How the mechanism is specified
- Taken from the specification, the next constraint is: This permits reducing the bandwidth used for transaction propagation from linear complexity in the number of peers to square root; and also reducing the initial transaction exchange from 10s-100s MB to len(pool) 32B ~= 128KB.
- Locate eth/65: transaction announcements and retrievals in EIP 2464 and apply it to one transaction or call.
- Then check the failure the class of rule always has: a node that did not upgrade, a reverted call, a replayed signature, or a peer that does not speak the message.
What this page does not treat as proven
Why the desk still reads it
Use EIP 2464 when a pitch says 'eth/65: transaction announcements and retrievals' without saying whether the rule is consensus, policy, or an interface. The number is the citation. The pitch is not.
