THE TRUST MACHINE


Definition N2

Ledgers, the foundation of accounting, are as ancient as writing and money.

A DISTRIBUTED LEDGERWHAT IS THE BLOCKCHAIN?

Definition N3


• A blockchain is a tamper-proof, shared digital ledger that records transactions(history) that take place between the peers in a peer-to-peer network.

• All the confirmed and validated transaction blocks are linked and chained from the beginning of the chain to the most current block, hence the name blockchain.

MORE DETAILS

• 1 Vote = 1 CPU (Proof-of-work), Byzantine general problem.

• Only miners add Blocks (Data) to the blockchain.

• Everybody could become a miner.

• One miner is rewarded at time and its block is added to the blockchain.

HOW IT WORKS?

The computing power of the Bitcoin network is 7468 times higher than the one of the cumulative 500 world supercomputers.

Nascent technology

Resolving challenges such as lack of standards transaction speed, the verification process, and data limits will be crucial in making blockchain widely applicable.

Uncertain regulatory status

Because modern currencies have always been created and regulated by national governments, blockchain and Bitcoin face a hurdle in widespread adoption by pre-existing financial institutions if its government regulation status remains unsettled.

Cost & volatility

Blockchain offers tremendous savings in transaction costs and time but the high initial capital costs could be a deterrent.

Control, security, and privacy

While solutions exist, including private or permissioned blockchains and strong encryption, there are still cyber security concerns that need to be addressed before the general public will entrust their personal data to a blockchain solution.

Integration concerns

Blockchain applications offer solutions that require significant changes to, or complete replacement of, existing systems. In order to make the switch, companies must strategize the transition.

Cultural adoption

Blockchain represents a complete shift to a decentralized network which requires the buy-in of its users and operators.

Scalability

Data inside a blockchain cannot be deleted.
