Security Model Comparison
See how TBA's 1-1-1 key distribution is designed to reduce single points of failure
Detailed Comparison Table
▼The question is not only “how many keys exist?” It is “who controls the keys, who understands the plan, and what happens if that person is gone?”
Single-Sig
(one key)
(one key)
DIY Multisig
(one person controls all keys)
(one person controls all keys)
Collaborative Security
(independent keyholders)
(independent keyholders)
Key control
One key, one person
Multiple keys, but one person still controls all of them
Distributed across the client and independent keyholders
Transaction approval
The single keyholder signs alone
The owner signs alone using their own quorum
Client initiates; quorum across independent parties; nobody signs alone
Loss of one key
❌ Funds may be gone
✅ Usually survivable if backups are intact
✅ Survivable by design, with a documented path
Theft of one key
❌ Funds can be drained
✅ One stolen key is not enough
✅ One stolen key is not enough
Death or incapacity
❌ The plan dies with the person
⚠️ Often still fails: one person held all the knowledge
✅ Designed for it: documented recovery and prepared keyholders
Inheritance readiness
❌ Heirs need the seed itself
⚠️ Heirs face a system nobody else understands
✅ Recovery process built for heirs and fiduciaries
Divorce or family conflict
⚠️ One party controls everything
⚠️ The same person still controls everything
✅ Independent keyholders limit unilateral moves
Jurisdictional risk
❌ One location, one jurisdiction
⚠️ Usually concentrated where the owner lives
✅ Can be distributed across jurisdictions
Documentation burden
Low
High, and entirely on the owner
Shared: documentation is part of the model
Technical complexity
Low
High: setup, backups, wallet files, testing
Moderate for the client; the process carries the rest
False sense of security
⚠️ “It’s a hardware wallet, I’m safe”
⚠️ Highest: technically multisig, humanly centralized
Lower, if the conditions are real: verify keyholder independence
Best use case
Small balances, learning, spending wallets
Technically careful users who document and test their own recovery
Families, businesses, estates, fiduciaries: continuity needs
Main weakness
One failure can mean total loss
One person remains the operational single point of failure
Coordination, fees, provider selection, less unilateral control
DIY Multisig, Honestly
Multisig itself is not the issue. The issue is multisig where one person still controls the entire operational system. Both sides deserve to be said plainly.
Where DIY multisig genuinely helps
- Better than single-sig when set up carefully
- One stolen or damaged key does not automatically mean loss
- More sovereignty and privacy than relying on an outside cosigner
- A strong option for advanced users who document and test their own recovery process
Where it can still fail
- All knowledge and recovery power can stay concentrated in one person
- Heirs, spouses, or fiduciaries may not know what to do
- More complexity creates more ways to make mistakes
- If all keys and instructions sit under one person’s control, the setup may still fail like single-person custody
Who is each model for?
- Single-sig: small balances, learning wallets, early practice, simple spending. Not wrong, just limited.
- DIY multisig: technically careful people who understand quorums, backups, and wallet coordination, will test recovery, and do not need outside continuity support.
- Collaborative security: families where heirs need a path, business owners, trustees and fiduciaries, older clients, meaningful balances, jurisdictional exposure, and anyone who does not want one person to be the only operational point of failure.

Protecting Your Family: Inheritance Planning
Interactive Inheritance Scenario
▼Scenario: Client Passes Away
Without Planning
Single-Sig or 2-Key Custody
- Heirs must find seed phrase
- Seeds often lost or destroyed
- No guidance on wallet recovery
- Technical barriers for non-experts
- Bitcoin effectively lost
→
With TBA Planning
Collaborative Security
- TBA holds one key independently
- Heirs work with TBA + provider
- Estate plan provides clear instructions
- TBA guides heirs through process
- Bitcoin successfully transferred
How TBA Facilitates Inheritance
1
Estate Plan Created
Client establishes documented inheritance plan with TBA, including heir information and verification procedures
2
Event Occurs
Client passes away; heirs contact TBA with death certificate and estate documentation
3
Verification Process
TBA verifies heir identity and legal authority per estate plan protocols
4
Coordinated Recovery
TBA coordinates with wallet provider and heirs to access bitcoin (2 of 3 signatures from: heir with client's key, TBA, provider)
5
Transfer Complete
Bitcoin transferred to heir's wallet; TBA provides ongoing education and security guidance
Why TBA's Independent Key Matters
True Independence
TBA holds key separately from wallet provider—prevents single company failure
Expert Guidance
TBA educates heirs who may have zero bitcoin knowledge
Documented Process
Clear procedures prevent confusion during difficult times
Jurisdictional Safety
TBA can be in different jurisdiction from heirs, adding protection layer
Advanced Protection: Time-Locked Recovery
Interactive Time-Lock Scenario
▼Scenario: Provider Disappears
Day 0-89
Requires: 2 of 3 keys
You
Adviser
Provider (missing)
✓ Normal operations continue
→
Day 90+
Time-lock activates: 1 of 2 keys
You
Adviser
Provider (locked out)
✓ Full recovery without provider
Why This Matters
No Single Point of Failure
If any party disappears, you're not locked out forever
Time Gives Security
Attackers can't rush transactions; you have time to respond
Guaranteed Recovery
Your bitcoin remains accessible even if services shut down
Inheritance Planning
Heirs can access funds after specified time periods
Real Stories: Why This Matters
Real-World Examples
▼Mt. Gox: $450M Lost
2014
Single-sig hot wallets. CEO had full control. Keys compromised over time, funds slowly drained.
✅ Multisig would have prevented: Required multiple parties to authorize withdrawals. Theft detected earlier. No single point of compromise.
Lost Inheritance: Billions Locked
Ongoing
~20% of all BTC likely lost forever. Owners died without sharing seed phrases. Heirs find hardware wallets but can't access them.
✅ TBA model solves: Independent key holder facilitates inheritance. Documented estate plan. Heirs guided through recovery process.
Canadian Trucker Protest
2022
Government froze bank accounts and pressured centralized exchanges. Single-jurisdiction custody vulnerable to seizure.
✅ Geographic distribution protects: Keys in 3 jurisdictions. No single government can freeze all cosigners. Maintained financial sovereignty.
Common Misconceptions
Let's clear up some myths about collaborative security
Common Myths Debunked
▼❌ "Multisig is only for institutions and whales"
✅ Reality: Any amount worth protecting benefits from multisig. Services available from $10k+. Cost of loss >> annual fee. Think insurance, not luxury.
❌ "I'll lose access if TBA goes out of business"
✅ Reality: You + provider still hold 2 of 3 keys—sufficient to move funds. Time-locked recovery paths provide backup. TBA shutdown doesn't trap your bitcoin.
❌ "Hardware wallet = complete security"
✅ Reality: Hardware wallets protect against digital attacks, not physical loss, inheritance, or $5 wrench attacks. Multisig adds layers hardware alone can't provide.
❌ "Multisig is too complicated for regular people"
✅ Reality: You interact with simple interfaces. Providers handle technical complexity. Signing transactions as easy as 2FA login. Simpler than managing seed backup alone.
❌ "Get your Bitcoin off exchanges" means single-sig only
✅ Reality: You control YOUR key + 2FA authentication. Cosigners can't move funds without you. You maintain sovereignty with professional backup.
