I’ve taken a few weeks break from the blog, considering what to do next about financial systems. Today’s video though makes clear the major gap I see in blockchain.
Trust is at the core of the efficiency of today’s financial and business systems. But blockchain, as developed by Bitcoin, is premised on a “trustless” system.
One of the significant promises of blockchain is greater efficiency. And one can see how that can be possible through a shared ledger.
The problem is, that a trustless system adds such a burden to the shared ledger, that it becomes too costly; much more costly than today’s inefficient ledgers built on trusted transactions.
In a highly trusted relationship, such as in a family, pencil and paper have adequate security to record transactions in a ledger. In a slightly less trusted environment, such as a partnership, one might chose to use pen and ink, making things a bit harder to change.
Blockchain–the actual file format designed by Bitcoin developers–is like using a slab of granite and a jackhammer. Only in that way will I have confidence that when I have to fall asleep for eight hours each night, the counterparty won’t be able to sandblast the slab clean and re-chisel it with a fictitious set of transactions. But at the cost of using huge amounts of compute capacity recording each transaction all day long!
Fundamentally honest people–the “trustworthy”–have a significant competitive advantage over criminals. Blockchain in Bitcoin is effective for transactions with criminals, but will never replace the efficiency of today’s trusted systems of records.
A trust-based, shared ledger system will ultimately make today’s trusted systems of record even more efficient.
