an electronic payment system based on cryptographic proof instead of trust, allowing any two willing parties to transact directly with each other without the need for a trusted third party. The beginnings of Bitcoin on the internet in 2008-2009

Bitcoin as described on sourceforgeBitcoin is a decentralized P2P (peer-to-peer) electronic cash system without a central server or trusted parties.
Users hold the crypto keys to their own money and transact directly with each other, with the help of the network to check for double-spending.

networks.Adapted from Lvy 1997

14Here is a quotation from Pierre Levy, a researcher who studies collective intelligence, or . He says, No one knows, but I have adapted this to be that all knowledge resides in networks. What good is knowledge if you cannot access it? Knowledge is created and transferred through networks. How many of you have heard of six degrees of separation? (raise hands)this means that we are collected to all other human beings on the face of the planet through six links, where a link is from me to person x in audience. Thus, each of us actually has access to all knowledge and resources that exist. (Next slide)

How does Bitcoin work?https://99bitcoins.com/get-your-first-bitcoin/
https://bitcoin.org/en/
https://bitcoin.org/en/how-it-works: The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.

The chances are that when Alice wants to send bitcoins to Bob, she wont have exactly the right number of bitcoins from other transactions. Perhaps she only wants to send 1.5 BTCto Bob.None of the transactions that she has in her bitcoin address are for that amount, and none of them add up to that amount when combined. Alice cant just split a transaction into smaller amounts. You can only spend the whole output of a transaction, rather than breaking it up into smaller amounts.Instead, she will have to send one of the incoming transactions, and then the rest of the bitcoins will be returned to her as change.Alice sends the two bitcoins that she got from Jane to Bob. Jane is the input, and Bob is the output. But the amount is only 1.5 BTC, because that is all she wants to send. So, her wallet automatically creates two outputs for her transaction: 1.5 BTC to Bob, and 0.5 BTCto a new address, which it created for Alice to hold her change from Bob.

Displaces roles of trusted third partiesCant do same transaction twice No transaction repudiation Initial entry requires trust but then system operates on trustless basis

Enabling smart contractsImagine a blockchain-based script that is activated when two parties sendbitcoins to an escrow Bitcoin account controlled by the script, and which willrelease the bitcoins in the future to whoever wins a bet on the average level of rainfallover a certain period. This smart-contract is programmed to read data from weatheragencies, and after a set amount of time releases the bitcoins from the escrow, sending itto a farmer who requires protection against low rainfall. This is a blockchain-basedweather derivatives contract.-Brett Scott

"In the absence of a centralized server brokering messages, supporting file storage and transfers, and arbitrating roles and permissions, any decentralized IoT solution should support three foundational types of transactions: Trustless peer-to-peer messaging Secure distributed data sharing A robust and scalable form of device coordination."

Most of what we need to know to make good decisions today is outside our comprehension: We dont even know its there.
