Three years ago you borrowed money on Aave. Market volatility kept you from adding collateral in time, and you were liquidated. Now you want to borrow from another protocol, but your interest rate is higher than everyone else's. That is because the "overdue record" tied to your wallet address is still visible on-chain.

This problem is more complex than most people think. On-chain data is fundamentally different from traditional credit records, but saying it "follows you forever" is not completely accurate either.
How long does a record live? It depends on who reads it
First, separate two ideas: the on-chain data itself and how protocols use it.
On-chain data itself cannot be changed. The liquidation transaction, once included on-chain, will exist in Ethereum's history forever. This is not a technical weakness; it is how blockchain works. You can check every interaction an address has made from the genesis block to now. From this view, an "overdue record" really does stay with that address.
But how a protocol uses that data is a different story. Credit is really about "can future behavior be predicted", not "did you make a mistake in the past". That is also why a credit scoring model is different from a permanent blacklist.
The key difference: scoring models focus on behavior trends, blacklists focus on a single event.
Scoring models (such as Spectral Finance's MACRO score) combine your repayment history, current asset situation, wallet activity and other factors into a dynamic score. A liquidation record will affect the score, but if you later show stable repayment behavior, the score can recover. One academic study trained a random forest credit model on 1.1 million Aave transactions and reached an R² of 0.953. This shows that behavior patterns can be measured and are dynamic.
A hard blacklist is completely different. If a protocol or compliance tool labels your address as "high risk", gives no appeal process, and rejects all lending requests, then the effect of that record may really be "permanent" — unless the project team updates the blacklist.
Ways records are "removed" in practice: new addresses, cross-chain moves, and credit identity migration
On-chain records cannot be deleted technically, but in the real world people use several workarounds:
1. Using a new address is the most direct solution, but it has real costs. A brand-new address has no history, which means a blank credit profile and little access to credit. If you switch addresses several times and they are linked to you, you may also trigger Sybil detection.
2. Cross-chain migration hides records, but that is not always good. Your overdue record on Ethereum is invisible by default on Arbitrum. But you lose not only bad records, but also good ones. A new address cannot prove the repayment ability and activity you built on Ethereum. Credit scoring data does not automatically cross chains unless a special cross-chain identity aggregation system exists.
3. Credit identity protocols (such as Bloom and Spectral) offer another possibility: bind your credit record to a portable digital identity instead of the wallet address itself. Bloom's BloomScore model is based on the idea that "credit follows the person". In theory, you can migrate your credit identity to a new address and keep using your past credit history. But adoption of these solutions is still low, and the scoring model may still look at the original address's history.
The most common misunderstanding: treating "permanently unchangeable" as "permanently blacklisted"
On-chain records cannot be deleted, but that does not mean you can never borrow again. Credit scoring naturally needs updated data, not fixed labels.
A more realistic answer is: the specific on-chain record is permanent, but its continuing effect depends on the model used by whoever is evaluating you. As ChainScoreLabs has pointed out, permanent records with no appeal or recovery mechanism could create a "digital caste system".
But most lending protocols have not gone that far. In most cases, as long as you show good repayment behavior later, the effect of one past liquidation will gradually weaken. That is not because the on-chain record disappeared. It is because protocols care more about "your behavior over the last 12 months" than "a mistake you made three years ago".

How to check your own situation
If you are worried that your wallet history may affect future borrowing, you can do three things:
Check your wallet in mainstream scoring models: Use a platform like Spectral to check your MACRO score and see if there are any unusual flags.
Review recent repayment history: Have your repayments in the past six months all been on time? If you nearly got liquidated, keep things stable for a few months before applying again. Your score should recover naturally.
Consider whether cross-chain migration is necessary: If you plan to start over on a new chain, consider migrating your credit identity too, instead of abandoning an address that has a good history.
