Google Whitepaper Spotlights Algorand’s 44% Rally, PayPal Checkout Growth Slows
A Google quantum computing whitepaper published March 31 highlighted Algorand’s deployment of post-quantum Falcon signatures, fueling a 44% rally over the past week. PayPal’s branded checkout growth slowed to 1% in Q4 as alternatives like Apple Pay and Google Pay gain traction.
1. Google Publishes Post-Quantum Whitepaper
On March 31, Google released a whitepaper titled “Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities,” identifying Algorand as an early adopter of post-quantum cryptography. The report noted Algorand’s use of Falcon digital signatures for smart transactions and state proofs, with its first PQC-secured transaction executed in 2025.
2. Algorand Rallies on Quantum-Resistant Narrative
Algorand’s token price jumped 13% in 24 hours to $0.12 and surged 44% over the past week as investors focused on quantum computing risks. Its mainnet implementation of PQC key rotation and signature schemes has become a market theme backed by institutional research support.
3. PayPal’s Branded Checkout Faces Competition
In Q4, PayPal’s branded checkout growth decelerated to just 1%, prompting executive turnover and a $400 million investment to revitalize its payments button. Online merchants and shoppers increasingly favour mobile wallet options such as Google Pay and Apple Pay over traditional PayPal flows.
