What T.A.L.A. is and why time locks matter.
Security Stack
Encryption, blockchain, IPFS, and audit trails.
Real World Use
Education, governance, legal, and safety.
Mathematical Trust
Unlock rules live on chain and cannot be bypassed.
User-Controlled
Keys stay with you. We never see your data.
Auditability
Every action is recorded and independently verifiable.
WHAT IS T.A.L.A.?
A transparent authority for time locked data, built on encryption, smart contracts, and decentralized storage.
T.A.L.A. Stands For
Transparent Authority Locked Assurance
A blockchain based system where time, encryption, and cryptography replace trust in institutions.
Core Promise
Lock sensitive data with guaranteed unlock times
Encrypt with keys only you control
Verify integrity through blockchain audit trails
Key Difference
Traditional Systems: Trust institutions
T.A.L.A.: Trust mathematics
The Problem We Solve
✗ TRADITIONAL SYSTEMS
- ✗Depend on institutional trust
- ✗Servers can be hacked
- ✗Audit trails can be altered
- ✗Early access possible
- ✗Single point of failure
T.A.L.A. APPROACH
- Mathematical certainty
- Blockchain enforces rules
- Immutable audit trail
- Time lock guarantees
- Decentralized & resilient
HOW T.A.L.A. WORKS
Six steps, zero shortcuts. Everything is enforced by math, not by policy.
Choose a future unlock time and upload files
Connect your wallet. Set the unlock date and time. Files are encrypted on your device using AES-256-GCM. Your key never leaves your computer.
Smart contract records the vault on the blockchain
The contract stores the vault ID, creator address, unlock timestamp, and file hashes. Once created, the unlock time cannot be changed.
Time passes. The blockchain enforces the schedule
You receive notifications 24 hours before unlock. During this period the vault remains locked, files are encrypted, and access is not possible.
At the timestamp, the contract changes state automatically
At the exact time, the contract state changes and the vault becomes accessible. Anyone with the ID can retrieve the encrypted files.
Recipients use the encryption key to decrypt files
Only the encryption key you control can decrypt. You share the key out of band. T.A.L.A. never sees it. Decryption happens on the recipient device.
The blockchain proves vault history and integrity
All actions are verifiable on chain, including creator, timestamps, and file hashes. The audit trail cannot be altered.
The Timeline Guarantee
Unlock time is fixed and cannot be changed.
• Unlock time is stored by smart contract
• The creator cannot modify the schedule
• T.A.L.A. cannot override the contract
• Early access is not possible
• Access begins only at the exact timestamp
SECURITY ARCHITECTURE
Five overlapping layers protect every vault. Compromise one, four still stand.
Layer 1: Device Encryption
AES-256-GCM encryption on your device. Keys are never sent to servers. Authenticated encryption prevents tampering.
Layer 2: Blockchain Lock
The smart contract enforces unlock time. It is immutable and cannot be overridden. This is guaranteed by the Polygon network.
Layer 3: Decentralized Storage
Files are stored on IPFS, not on centralized servers. Multiple pinned copies reduce dependency on any single host.
Layer 4: Access Control
Wallets prove ownership through cryptographic signatures. No passwords. No credential database. Resistant to guessing attacks.
Layer 5: Audit Trail
All actions are logged on the blockchain. The record is permanent and cannot be altered.
What This Means
- • Even if T.A.L.A. servers are compromised, files remain encrypted
- • Even if a node fails, IPFS storage remains accessible
- • If a wallet is lost, the vault stays locked until the scheduled time
- • The audit trail remains immutable and verifiable
CORE FEATURES EXPLAINED
Each feature is designed to remove human trust and replace it with cryptographic guarantees.
AES-256-GCM Encryption
Bank grade encryption used by governments and financial institutions. Files are encrypted locally before upload. Keys never reach our servers. Authenticated encryption detects tampering.
Smart Contract Time Locking
Unlock times are enforced by immutable blockchain code. This is a cryptographic guarantee and cannot be bypassed.
Non Custodial Key Management
You hold your encryption keys. T.A.L.A. never stores them. Even administrators cannot decrypt your vaults.
IPFS Decentralized Storage
Files are stored on IPFS, not on T.A.L.A. servers. They are pinned to Pinata nodes for reliability and resilience.
Immutable Audit Trail
Every action is logged on Polygon, including vault creation, file uploads, sharing, and access attempts. This creates a tamper evident record.
Instant Access After Unlock
Once unlocked, vaults are accessible immediately. There is no approval workflow or manual intervention required.
REAL WORLD USE CASES
Education
Exam Security
Instructors create time locked exam papers. Papers unlock at the scheduled exam time. This prevents early access and replaces trust with cryptographic certainty.
REAL EXAMPLE:
A university publishes 100 exam papers locked until 9:00 AM. At 9:00 AM, all students get access.
Governance
Fair Procurement
Agencies lock contractor bids until the official opening. Bids remain encrypted until the public opening time, improving fairness and auditability.
REAL EXAMPLE:
A city publishes an RFP with five bids. At 2:00 PM on opening day, all bids unlock simultaneously.
Legal
Evidence Protection
Whistleblowers encrypt documents with a future unlock date. Journalists can lock investigations until a publication date while keeping the content private.
REAL EXAMPLE:
A journalist locks an investigation until publication day. The release cannot be stopped once locked.
Security
Inheritance and Contingency Release
Users lock sensitive data to unlock at a scheduled time, supporting digital legacy planning without intermediaries.
REAL EXAMPLE:
Recovery codes are locked to unlock in five years and release automatically on schedule.
