BLOCKCHAINS BACK IN 2015
CAN’T COMMUNICATE
POOR GOVERNANCE
CAN’T SCALE
NO CUSTOMIZATION
UPGRADES ARE DIFFICULT
Interchain communication was never part of the design
Decisions on many legacy networks are made by one powerful individual or group
These networks can’t handle a lot of traffic
One-size-fits-all application platforms do not work for every blockchain use-case
Users of the network must independently upgrade their software
THE FUTURE OF WEB3 ISN’T BASED ON A SINGLE BLOCKCHAIN.��THERE IS NO ‘ONE SIZE FITS ALL’.��WEB3 DEPENDS ON OPENNESS AND INTEROPERABILITY.
POLKADOT VISION
POLKADOT IS A SET OF BLOCKCHAINS THAT CAN TALK TO EACH OTHER AND WORK TOGETHER SECURELY.
POLKADOT IS A HETEROGENEOUS MULTICHAIN PROTOCOL THAT SECURES AND CONNECTS BLOCKCHAINS WITH POOLED SECURITY AND INTEROPERABILITY.
