May nag-send sa'yo ng Bitcoin tapos sabi, "Wait lang 10 minutes." After 30 minutes, wala pa rin? Nag-GCash ka, instant! Bakit ganun? Is Bitcoin really slow, or may deeper reason?
Sa article na ito, aalamin natin ang truth about Bitcoin's speed - the good, the bad, and why it's designed that way. Plus, the solutions being built para mas bumilis!
The Numbers: Bitcoin Speed vs Others
Transaction Speed Comparison
Bitcoin
- Transactions per second: 7 TPS
- Block time: 10 minutes
- Full confirmation: 60 minutes (6 blocks)
Traditional Payment Systems
- Visa: 65,000 TPS (wow!)
- PayPal: 193 TPS
- GCash/PayMaya: 1,000+ TPS
Other Cryptocurrencies
- Ethereum: 15 TPS
- Solana: 65,000 TPS
- XRP: 1,500 TPS
Looking at numbers, Bitcoin seems super slow! Pero wait, may reason yan...
Why 10 Minutes? The Design Decision
Si Satoshi Nakamoto deliberately chose 10 minutes. Hindi siya nag-random number generator! Here's why:
1. Network Propagation Time
Bitcoin nodes scattered worldwide - US, Europe, Asia, even sa Mars (joke!). Need time para:
- Transaction reach all nodes
- Nodes verify authenticity
- Consensus achieved globally
Too fast = some nodes left behind = network split risk!
2. Security vs Speed Trade-off
Fast transactions = Less secure
- 1 minute blocks = easier to attack
- 10 minute blocks = need massive resources
- Cost to attack Bitcoin: ₱750 million per hour!
Parang choosing between:
Habal-habal: Fast but risky
Armored car: Slow but secure
3. Preventing Double Spend
The 10-minute gap ensures:
- Same Bitcoin can't be spent twice
- Network has time to detect fraud
- Miners can properly order transactions
Real-World Bitcoin Transaction Timeline
Let's follow Juan sending 0.1 BTC to Maria:
0 seconds: Transaction Broadcast
Juan clicks "Send" - transaction spreads to network like chismis sa barangay!
1-3 seconds: Mempool Entry
Transaction enters "waiting area" with thousands others. Priority based on fees paid.
0-30 minutes: Mining Competition
Miners racing to include transaction in next block. Higher fee = better chance!
~10 minutes: First Confirmation
Transaction included in block! But wait, not yet final...
20-60 minutes: Full Confirmation
Standard practice: Wait 6 blocks (6 confirmations) for large amounts. Why? Super secure na!
The Scalability Trilemma
Blockchain has "impossible trinity" - pick only 2:
- Decentralization - Many nodes, no central control
- Security - Resistant to attacks
- Scalability - Fast and cheap transactions
Bitcoin's choice: Decentralization + Security
Sacrifice: Scalability (that's why slow!)
Other chains' choices:
- Solana: Security + Scalability (less decentralized)
- BSC: Scalability + partial Security (centralized)
Why Bitcoin Transactions Get Stuck
1. Network Congestion
Like EDSA traffic! When many transactions:
- Mempool fills up (300,000+ waiting)
- Only highest fees get through
- Low fee transactions wait... and wait...
Peak congestion times:
- Bull market peaks
- Major news events
- NFT launches (yes, on Bitcoin too!)
2. Low Transaction Fees
Kuripot sa fee? Prepare to wait!
- High priority: 50+ sats/byte (₱50-200)
- Medium: 20-50 sats/byte (₱20-50)
- Low: Below 20 sats/byte (antay ka!)
3. Block Size Limit
Each Bitcoin block = 1MB only
Average transaction = 250 bytes
Max transactions per block = 4,000 only!
Imagine jeepney with 4,000 seats, pero 50,000 waiting passengers!
The Great Block Size War (2015-2017)
Bitcoin community fought over how to scale:
Big Blockers Camp
"Increase block size to 8MB, 32MB, or more!"
- More transactions per block
- Lower fees
- Result: Bitcoin Cash (BCH) fork
Small Blockers Camp
"Keep 1MB, build second layers!"
- Maintain decentralization
- Anyone can run node
- Result: Bitcoin + Lightning Network
Who won? Bitcoin (BTC) kept 1MB and worth ₱2.5M. Bitcoin Cash (BCH) has big blocks but worth ₱25K only.
Lightning Network: Bitcoin's Speed Solution
Imagine Bitcoin as highway, Lightning Network as skyway above it!
How Lightning Works
- Open channel: Lock Bitcoin in smart contract
- Transact freely: Unlimited transactions off-chain
- Close channel: Final balance recorded on Bitcoin
Like bar tab - order many drinks (instant), pay once at end (on-chain)!
Lightning Network Stats
- Speed: Instant (milliseconds!)
- Capacity: Millions TPS possible
- Cost: Less than ₱1 per transaction
- Nodes: 15,000+ worldwide
- Capacity: 5,000+ BTC locked
Real Use Cases Today
- El Salvador: Chivo wallet uses Lightning

Other Scaling Solutions
1. Segregated Witness (SegWit)
Implemented 2017. Moves signature data outside block.
- Effective block size: 1MB → 4MB
- More transactions fit
- 40% capacity increase
2. Taproot (2021)
Privacy and efficiency upgrade
- Batch multiple signatures

- Lower fees for advanced uses
3. Sidechains
Liquid Network: For exchanges and traders
- 1-minute blocks
- Confidential transactions
- Used by 50+ exchanges
RSK: Smart contracts on Bitcoin
- 30-second blocks
- Ethereum-compatible
- DeFi on Bitcoin
Transaction Speed in Different Scenarios
Buying Coffee (₱200)
Bitcoin mainnet: Impractical - ₱100 fee, 10-minute wait
Lightning Network: Perfect! Instant, ₱0.50 fee
Verdict: Use Lightning for small purchases
Sending to Family (₱10,000)
Bitcoin mainnet: Good - ₱100 fee worth it
Bank transfer: ₱50-150 fee, 1-3 days
Verdict: Bitcoin competitive
International Business (₱1,000,000)
Bitcoin mainnet: Excellent - ₱200 fee negligible
SWIFT wire: ₱3,000-10,000 fee, 3-5 days
Verdict: Bitcoin wins big!
Emergency Remittance
High fee Bitcoin: 10-30 minutes
Western Union: Minutes but high fees
Verdict: Depends on urgency vs cost
Tips to Speed Up Bitcoin Transactions
1. Check Network Status
Websites to monitor:
- mempool.space - Visual mempool
- bitcoinfees.earn.com - Fee recommendations
- blockchain.com - Network stats
2. Use Dynamic Fees
Wallets with smart fee estimation:
- Electrum
- Blue Wallet
- Exodus
3. Replace-By-Fee (RBF)
Stuck transaction? Bump the fee!
- Enable RBF when sending
- Increase fee if stuck
- Miners prioritize higher fee
4. Time Your Transactions
Best times (Philippine time):
- Weekends: Lower volume
- 2-6 AM: US sleeping
- Avoid: US market hours
5. Use Lightning for Appropriate Amounts
- Below ₱5,000: Lightning better
- Above ₱50,000: Mainnet fine
- In between: Depends on urgency

- MAST: Complex scripts simplified
- Covenants: Advanced transaction types
Layer 3 Solutions
Building on top of Lightning:
- Fedimint: Community banks
- Cashu: Privacy-focused
- RGB: Smart contracts
Bitcoin Speed: Feature or Bug?
The truth? Bitcoin's "slowness" is intentional design for security. It's like comparing:
- GCash = Tricycle (fast for short trips)
- Bitcoin = Airplane (preparation time but crosses oceans)
Different tools for different purposes!
Common Misconceptions
"Bitcoin Will Never Scale"
Reality: Lightning Network already processing millions of transactions. Scaling happening on Layer 2!
"Other Coins Are Better Because Faster"
Reality: They sacrificed decentralization or security. No free lunch in blockchain!
"10 Minutes Is Too Slow for Modern World"
Reality: Credit cards take 60-180 days to truly settle. Bitcoin's 60 minutes is actually fast for final settlement!
"High Fees Make Bitcoin Unusable"
Reality: Fees depend on use case. ₱100 fee on ₱1M transfer = 0.01%. Try that with banks!
Practical Advice for Filipinos

Final Thoughts: Slow and Steady Wins?
Yes, Bitcoin is "slow" compared to Visa or GCash. But it's comparing apples to oranges. Bitcoin offers:
- True finality in 60 minutes (vs 180 days chargebacks)
- Global reach without permission
- Uncensorable transactions
- Predictable monetary policy
Speed isn't everything. Sometimes, security and decentralization matter more. And with Lightning Network, we can have both!
