The document discusses solutions to scalability issues facing bitcoin transactions, including increasing the block size limit and using payment channels. It provides examples of the Lightning project and Stremium, which enable microtransactions through off-blockchain payment channels. Payment channels allow multiple transactions to be aggregated into a single transaction through the use of multi-signature wallets and time-locked transactions. This could enable billions of transactions per day and provide programmable consumer protections like automatic refunds or arbitration.

Bitcoin - Passing Fad? Disruptive Technology? Either Way It's Now Taxable!Tom Hood, CPA,CITP,CGMA
Bitcoin has been making major headlines recently. Starting with a year-end high price of $817.12 which would have returned 56X or 5,600% in 2013 to the over $500 million theft from the Japanese exchange Mt. Gox in February. Then Apple removes the Bitcoin app from its app store and finally the IRS announces its position on the taxability of virtual currencies on March 25, 2014.
Which raises the question, is Bitcoin a passing fad or disruptive technology that we need to take seriously?
This deck covers the background and latest information about Bitcoin and the IRS guidance on taxation and virtual currencies.

Bitcoin - First Blockchain Implementation -- What is it? How can it be used? ...Prashant Shahi
This slide briefly explains what Bitcoin is, how can it be used, how it works and their limitations. This slide answers Often Asked Questions about Bitcoin !!
Blockchain has gained lots of attention in recent years. Bitcoin and Ethereum are leading the race. Crypto currencies in spite of uncertainty and volatility are here to stay. Smart contract programming is the future for the Internet 3.0.
Bitcoin Technology” Bitcoin is an innovative technology that offers several benefits, such as fast transaction speeds, low costs, and the elimination of the need for a third-party intermediary to process transactions. Unfortunately, BitCoin has faced resistance from regulators because the technology has been used for nefarious purposes, including online drug purchases and Ponzi schemes. This note provides a basic explanation of how BitCoin works and is currently regulated on federal and state levels. This note argues that BitCoin should not be forced into old regulatory frameworks that do not adequately balance security concerns with the benefits of BitCoin. BitCoin should not be regulated at the federal level. Instead, state regulations should focus on BitCoin providers that can unilaterally transfer or block transfers of BitCoin on behalf of users. State regulators should require such providers to register with their given states, maintain adequate books and records, implement advanced cyber security standards, conduct audits of their operations, and submit reports to state regulators. In crafting these regulations, regulators should keep in mind that vague or poorly drafted regulations will chill innovation. A Bitcoin would allow online payments to be sent directly from one party to another without going through a financial institution. Digital signatures provide part of the solution, but the main benefits are lost if a trusted third party is still required to prevent double-spending. We propose a solution to the double-spending problem using a peer-to-peer network.

Blockchain Fundamentals Explained In Simplest WayeTailing India
Currently, most people use a trusted middleman such as a bank to make a transaction. But blockchain allows consumers and suppliers to connect directly, removing the need for a third party.
Using cryptography to keep exchanges secure, blockchain provides a decentralized database, or “digital ledger”, of transactions that everyone on the network can see. This network is essentially a chain of computers that must all approve an exchange before it can be verified and recorded.
This presentation is about blockchain.
When Thomas Edison invented the electric lamp in 1879, he did not make a market analysis. The market did not have an identified need for a lamp but for light. This is a kind of disruptive original ideas.
Satoshi Nakamoto (a person or a group) did not do a market analysis neither . The blockchain was born after the financial crisis of 2008 as people lost trust in banks.
Satoshi Nakamoto introduced a new model of trust based on cryptographic proof in a decentralised & distributed ledger.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:

Programmable consumer protection and scalabiity
1. Scalability and Programmable
Consumer Protection
William K. Santiago (william@wksit.com)
Twitter (#williamsantiago)
Certified bitcoin Professional (CBP ID 69d4e6)
4. Solution Options
Payment Channels or Transaction Channels
Increase block size from 1MB to 20MB 8MB
1.No increase in block size, fork will
happen or Increase in block size, extend
functionality
2.Bitcoin XT is released it gets the majority
for a hard fork
6. Transactions per day
VISA handles on average around 2,000
transactions per second (tps)
PayPal, in contrast, handles around 10 million
transactions per day for an average of 115
tps
Today the Bitcoin network is restricted to a
sustained rate of 2 tps due to the bitcoin
protocol restricting block sizes to 1MB
7. 2015 The Year of MicroPayments
New technologies for MicroPayments
“Payment Channels” or “Transaction Channels”
Examples:
The Lightning project
Enables micro transactions and off-blockchain transactions
Potential solution for the block size limit
Reduce the burden on the blockchain for smaller transactions
Stremium
Platform for streaming video and receiving payment by the second
(micropayments)
8. Lightning project
A decentralized system whereby transactions
are sent over a network of “payment
channels” whose transfer of value occurs off-
blockchain
Bitcoin transactions may occur between
untrusted parties and secured by the bitcoin
blockchain
10. What are “Payment Channels”?
Introduced a while ago (not a new idea)
Uses multi-sig
Allows two people to send transactions to
each other without hitting the Bitcoin
blockchain
The use of nLockTime (ability to postdate a
transaction) transaction becomes valid or
gets mined at a certain time in the future
11. What does “Payment Channels” do?
Aggregates lots of transactions into a single
transactions
“Single Transaction” Create a multi-sig
transaction that gets funded and gets payed
post-dated into the future
“Micro Transactions” Exchange signed
transactions but do not get processed unless
either party wants to settle account
12. With “Payment Channels” or Block
Size Increase
Bitcoin can scale to billions of transactions per
day or 11,500 transactions per second (tps)
Provide Programmable Consumer Protection
13. Programmable Consumer Protection
Time trigger refund
3rd party escrow
Arbitration services
Example:
Payment channel between three parties where you pay a
merchant to buy a flat screen TV and part of that payment
you have an automatic 30 day refund. If there is a dispute
the 3rd party can step in and do an escrow transaction to
refund the consumer.
