State Street Explains...
Blockchain in Five
It powers the Bitcoin
system, but can enable many
other financial applications
and interactions.
Having a shared, validated
and distributed ledger can
help speed reconciliation,
shorten settlement time
and automate processes.
Blockchain applications
behave the way we
need them to — open and
public, or permission-
based and private.
Cryptography is a key
part of a blockchain.
It ensures the data
can be distributed and
still be secure.
Huge potential that will
only be unlocked through
experimentation and
by addressing regulatory,
governance and
technical challenges.
