Matt Hamilton didn’t mince words. Ripple’s former chief engineer called a proposed expansion of the XRP Ledger’s transaction Memo field “a really bad idea” — and he’s got reasons that go well beyond personal preference.
The proposal, backed by members of the XRPL Foundation, wants to raise the Memo field limit from 1 KB to 1.3 MB. That’s a 1,200-times increase. The idea is to let users embed files directly into ledger transactions, paying fees for the privilege of storing content on-chain. Supporters frame it as a freedom-of-use argument — if you’re willing to pay, why shouldn’t you be able to store what you want? But Hamilton sees something much more dangerous underneath that logic. He fears the XRP Ledger would stop being a payment ledger and start becoming an inefficient file-sharing service — a transformation that, in his view, would gut the network’s core value proposition.
Not a small concern.
What a 1.3 MB Memo Field Actually Means
Every node on the XRP Ledger keeps a full copy of the transaction history. That’s how the network works. It’s also why Hamilton’s warning carries weight. If users start embedding large media files into transactions — images, documents, audio clips, whatever — the database doesn’t just grow. It balloons. Fast. And it probably doesn’t stop.
Hardware requirements would follow. Bigger database means more storage, more processing, more cost. For large institutional node operators, that’s annoying but manageable. For smaller, independent participants — the kind that keep a decentralized network actually decentralized — it’s basically a death sentence. They can’t keep up. They drop out. The network concentrates. And the whole decentralization pitch that XRPL has built its reputation on starts to look pretty hollow.
Hamilton’s criticism isn’t just theoretical. He’s pointing at a structural reality: the ledger was never designed for this. Its architecture prioritizes speed and scalability as a payment tool. Packing it with large files works against both of those goals simultaneously.
Hamilton’s Fix: Use Filecoin, Leave XRPL Alone
Hamilton isn’t saying don’t store files. He’s saying don’t store them on XRPL. His suggestion is to use decentralized storage networks — he specifically names Filecoin — for large media content. Those platforms are built for exactly that job. They handle big files efficiently, they’re designed to scale that way, and they don’t drag a payment ledger into territory it was never meant to occupy.
The hybrid approach he’s pushing would link XRPL with specialized storage networks. Users get the functionality they want. The ledger stays lean. Node operators don’t face runaway costs. It’s a cleaner solution, and it’s not like the technology doesn’t exist — it does, right now, and it works.
There’s a broader point buried in his argument too. Blockchain communities keep running into the same tension: the pull toward adding new features versus the discipline of staying true to what a system was built to do. XRPL was built to move value quickly and cheaply. That’s its edge. Diluting that edge to accommodate file storage — when dedicated tools already exist — seems like a bad trade, and Hamilton is pretty clear that he thinks so.
The XRPL Foundation members backing the proposal haven’t backed down, though. The debate is ongoing, and it’s unclear yet how the community will ultimately land on this. No vote timeline has been specified publicly, and details on exactly which Foundation members are driving the push remain murky.
What’s clear is that the stakes aren’t trivial. If the proposal passes and large files start flowing through the ledger, the database growth could become unsustainable in ways that are hard to reverse. Pulling back from that kind of architectural shift — once node operators have already been priced out and the network has already concentrated — would be enormously difficult. Maybe impossible.
Hamilton’s read is that the right moment to stop this is now, before it starts. Use Filecoin. Keep XRPL fast. Don’t turn a payment ledger into something it was never supposed to be.
The XRPL Foundation has not publicly responded to Hamilton’s specific criticisms as of the time of writing.

Frequently Asked Questions
What exactly is the proposed change to the XRP Ledger Memo field?
The proposal seeks to increase the XRP Ledger’s transaction Memo field limit from 1 KB to 1.3 MB — a 1,200-times expansion — allowing users to embed files directly into ledger transactions by paying associated fees.
Why does Matt Hamilton oppose the XRPL Memo field expansion?
Hamilton, Ripple’s former chief engineer, warns the change could cause the ledger’s database to grow at an unsustainable rate, raise hardware costs for node operators, threaten network decentralization, and turn XRPL from a payment ledger into a file-sharing service.
