clients, organizations and even investors
left Bitcoin

came into existence raising the block size
limit to 8MB as a component of a huge on-
chain scaling approach.

Cash has expanded the breaking point to
8MB,

Problem with Bitcoin

causing problem in transaction

block size but no agreement in the
community
• hit the ‘invisible wall’ in 2017

delay in confirmation of
transactions.

Bitcoin Security &
Privacy

Introduction
There are number of privac
y and security risks th
at comes along this virt
ual currency e.g risk of
hacking
Public and private keys
Bitcoin does not have any physi
cal existence that makes it
difficult to safeguard them

01 Theft From
Storage
Device
 Private keys and sensitive information
 How to avoid from theft ?
 Australian bitcoin holding bank
02 Theft From
Coinbase
Accounts
 Coinbase accounts
 Danger of hacking
 Protection of coinbase accounts
 Two way authentication
03 Theft from
Email
 Private keys are on risk of being stolen
 Don’t share private keys
04 Theft from
Unreliable
Third Party
 Unreliable exchane or mining market
 Nicehash,one of the largest crytocurrency mining
place got hacked on Dec 06,2017
 How to avoid such incident / Hot wallet and cold
Theft

How to Secure
Double exchanges of blockchain and distorting the bitcoin
represent the most serious issue. A protected wallet is
expected to tackle such security issues. The security of the
electronic wallet in cell phones must be checked as cell
phones have gotten well known.
 The base innovation should likewise be confirmed since
vulnerabilities vary as per the programming language and
stage utilized for the improvement of the electronic wallet
condition.
The electronic wallet must have measures for secure
rebuilding whenever encroached by an assailant, check of a
double introduced for self-insurance, and assurance of the
rest of the information for reclamation.

How to Secure
The mining process of the Bitcoin is potentially vulnerable
under attacks like 51% attacks and ‘Selfish-mining’ attacks. To
provide security against the attack on mining process, the
framework of Bitcoin protocols needs to be changed and
since the Bitcoin is indeed a decentralized cryptocurrency.
We should be careful of the bitcoin company with which we
choose to do the business.
It can be stored offline like in USB.
While transferring the fund to someone, one should confirm
the wallet address is genuine.
