TimeBinder vs ProofLedger: which file timestamp suits you?

ProofLedger is an API-first service that records proofs on Polygon. TimeBinder records file fingerprints on Bitcoin. Here’s a fair side-by-side.

Your files never leave your computer. With TimeBinder, each file is hashed locally on your own device. Nothing is uploaded or stored by TimeBinder.

TimeBinder vs ProofLedger: the short answer

Both services record a file’s fingerprint (its SHA-256 hash) on a public blockchain, and neither stores your file. ProofLedger anchors each proof on Polygon and is built around an API. Its Free plan includes 100 API proofs a month, and its paid plans cost $19 or $79 a month. TimeBinder records on Bitcoin and is built for people timestamping their own files in a browser. Its Free plan includes 1 Token a month for one Pooled TimeBind of up to 10 files, with no credit card required. If you’re building an app that records thousands of proofs, ProofLedger is designed for that. If you want a Bitcoin record of a few important files, with no code involved, TimeBinder is the simpler fit. Both show only that a file existed no later than a recorded time.

What is TimeBinder? TimeBinder is a blockchain timestamping service. It shows that a digital file existed no later than a specific time, and that it still matches its fingerprint, by anchoring the file’s SHA-256 fingerprint to the Bitcoin blockchain. Files are hashed in your browser and never uploaded, and each TimeBind comes with a Proof of Time Certificate that can be checked later. It does not prove who created a file or that its contents are true.

TimeBinder vs ProofLedger at a glance

	ProofLedger (from its own site)	TimeBinder
Blockchain	Polygon	Bitcoin
Built for	Apps and platforms using its REST API, plus web uploads	People and teams timestamping files in a browser; API access on the Business, Business Plus and Enterprise plans

Where ProofLedger is stronger

Volume through an API. Its plans are counted in thousands of proofs a month, with webhooks and proof bundles. That suits a product that timestamps on behalf of its own users.
Speed. It says Polygon anchoring usually happens within a minute. A Pooled TimeBind is usually recorded within 24 to 48 hours, and often sooner, depending on Bitcoin network activity.
A large free allowance for testing. 100 API proofs a month costs nothing.
Checking without the company. Its proof bundle can be checked offline with an open-source tool, which a Pooled TimeBind can’t.

Where TimeBinder may suit you better

No code. You drag files into the browser, and a certificate with a QR code is ready to share.
Up to 10 files in one record. A contract, its drawings and a cover email can sit under one certificate.
Bitcoin. If you or the person you’re showing the record to would rather rely on Bitcoin, that’s the chain TimeBinder uses. Both are public blockchains, so this is a preference, not a rule.
A plain choice between cost and independence:
– Pooled (1 Token): Your fingerprint is grouped with other users’ in one shared Bitcoin entry, usually recorded within 24 to 48 hours, and often sooner, depending on Bitcoin network activity. It’s checked through TimeBinder.
– ASAP (3 Tokens): It gets its own Bitcoin transaction, sent straight away, and can be checked independently, without relying on TimeBinder.

The Pooled vs ASAP explainer covers the detail.

What a TimeBind shows, and what it doesn’t

What it shows

That this exact file existed no later than the time recorded on the Bitcoin blockchain
That a file shown later still matches its fingerprint: the same file gives the same fingerprint, and any edit gives a different one
An independent record that anyone you allow can check, without relying on your own systems

What it doesn’t show

It doesn’t show who made a file, or who owns it.
It doesn’t show the contents are true or accurate, or whether AI was used.
It doesn’t stop anyone copying or changing a file. It shows whether a file still matches its fingerprint.
A Pooled TimeBind can’t be checked without TimeBinder.
It can’t say how a court, client or anyone else will treat it.

ProofLedger’s pricing page makes the same point about its own proofs: “A proof shows that a file existed by a date, not who made it.” A TimeBind likewise shows that a file existed no later than the recorded time. This is general information, not legal advice. For advice about your situation, speak to a lawyer in your country. Pooled TimeBinds are verified through TimeBinder. ASAP TimeBinds can also be verified independently, from the certificate and the public Bitcoin blockchain. Checking is always free.

When TimeBinder isn’t the right tool

You need thousands of records a month from your own software. ProofLedger’s API plans are priced for that. TimeBinder’s API access is included in the Business, Business Plus and Enterprise plans (Business Plus has 150 Tokens a month).
You need a record within a minute or so. Polygon anchoring is faster than a Bitcoin transaction.
You want free records you check yourself with command-line tools. See TimeBinder vs OpenTimestamps.
Your process asks for an RFC 3161 timestamp. See RFC 3161 vs a blockchain timestamp.
You need a signature or identity check. A timestamp isn’t one.

TimeBinder pricing

Free: $0. 1 Token a month (1 Pooled TimeBind). No credit card required. Use it each month, as it doesn’t carry over.
Essential: $20 a month for 5 Tokens (5 Pooled, or 1 ASAP + 2 Pooled). A paid plan replaces the Free plan’s monthly Token. Unused Tokens roll over. Cancel any time.
Expert: $50 a month for 15 Tokens (15 Pooled, 5 ASAP, or a mix).
Extra Tokens: 1 for $5, 3 for $15 or 9 for $40. Tokens you buy never expire.
Business Plus: $299 a month for 150 Tokens. See business plans for teams.

Enterprise plans have custom Token limits and dedicated support. API access is included in the Business, Business Plus and Enterprise plans. Service terms for every plan are set out in the TimeBinder Terms and Conditions. Checking a TimeBind is free. Which plan do I need shows the maths.

TimeBinder vs ProofLedger: FAQ

What is the main difference between TimeBinder and ProofLedger?

ProofLedger records on Polygon and is built around an API priced in thousands of proofs a month. TimeBinder records on Bitcoin and is built for timestamping up to 10 files at a time in a browser.

Does either service store my file?

No. ProofLedger’s terms say your device sends the hash with the file name and some other details. TimeBinder calculates the fingerprint in your browser and never uploads your files.

Which one records faster?

ProofLedger says Polygon anchoring usually happens within a minute. A TimeBinder Pooled TimeBind is usually recorded within 24 to 48 hours, and often sooner, depending on Bitcoin network activity. An ASAP TimeBind gets its own transaction, sent straight away.

Can I check the records without the company?

ProofLedger describes an offline check with its open-source verify-proof tool. A TimeBinder ASAP TimeBind can be checked from the certificate and the Bitcoin blockchain. A Pooled TimeBind is checked through TimeBinder.

Does TimeBinder have an API?

Yes. API access is included in the Business, Business Plus and Enterprise plans. Business Plus is $299 a month for 150 Tokens. For a few files a month, the browser and the Free plan are enough.
