What is Blockchain?
as well as Blockbook™

Blockchain is the technology that underpins digital currencies (Bitcoin, Litecoin, Ethereum, etc). A blockchain, is a growing list of records, called blocks, that are linked using cryptography. Each block contains a cryptographic hash of the previous block, a timestamp, and transaction data.

Blockchain is resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without alteration of all subsequent blocks, which requires consensus of the network majority. This is immutability.

Blockbook™ is a decentralized system/platform powered by core Blockchain Technology

Blockbook™ leverages Blockchain Technology, to provide you with Smart Contracts, Semi-Decentralized Cloud and a Manipulation/Tamper-Proof history and storage of your data and documents, via Blockchain Posting and Timestamping.

10. What is the Blockbook™ Blockchain Network?

What is the Blockbook™ Blockchain Server?

The Blockbook™ Network is a decentralized system powered by the Blockbook™ cloud and the EOSIO Blockchain technology.

EOSIO is a blockchain platform designed for the real world. Built for both public and private use cases, EOSIO is customizable to suit a wide range of business needs across industries with rich role-based security permissions, industry-leading speeds and secure application processing.

How does the Blockbook™ Network work?
The Blockbook™ Network uses the Blockbook™ Blockchain Server for Posting, and the EOSIO Network for Timestamping.

How does the Timestamping work?
Timestamping creates a unique and universal fingerprint (called the hash) for every piece of content. If the input changes even the slightest, the hash becomes totally different.

This hash is added to the blockchain with a date and time. Because you have the input that results in this specific hash, you can prove that you had the content at that point in time.

Copyright Claim Helper Tool and Copyright Protection included, with Automated, downloadable proof using mathematical algorithms and the blockchain.

1. What is Blockchain Timestamping?

What is Blockchain Timestamping?

Blockchain Timestamping is the process of securely keeping track of the creation and modification time of a document or data in the blockchain. It allows interested parties to know, without a doubt, that a document in question existed at a particular date and time. By design a Bitcoin transaction includes a date and time, held on the Blockchain. By including a cryptographic digest of a file you can later certify that the data existed at that time.

From signing important documents like mortgage deeds and insurance contracts, to claiming contest winnings, to creating patents and even claiming scientific discoveries, there is no limit to the uses of this basic business functionality. Prior to the internet it was time and labor intensive.

In Blockchain timestamping, each block contains a Unix time timestamp. In addition to serving as a source of variation for the block hash, they also make it more difficult for an adversary to manipulate the block chain.

A timestamp is accepted as valid if it is greater than the median timestamp of previous 11 blocks, and less than the network-adjusted time + 2 hours. “Network-adjusted time” is the median of the timestamps returned by all nodes connected to you. As a result block timestamps are not exactly accurate, and they do not need to be. Block times are accurate only to within an hour or two.

Whenever a node connects to another node, it gets a UTC timestamp from it, and stores its offset from node-local UTC. The network-adjusted time is then the node-local UTC plus the median offset from all connected nodes. Network time is never adjusted more than 70 minutes from local system time, however.

Bitcoin uses an unsigned integer for the timestamp, so the year 2038 problem is delayed for another 68 years.

Document issuance history certification
Timestamping of issued documents can allow a public verification of the issue history which is permanently recorded on the public blockchains. There is absolutely no method of potential malicious amendment at a later stage.
Blockchain stamping allows a public verification of the document’s date, authenticity, origin, integrity & content without publicly exposing the content itself.

Certify possession of original content
Content signed by the user before timestamping, can be undeniably claimed to have been in the user’s possession & knowledge at the time of the blockchain time stamping.
A simple reference to the respective public blockchain ledger transaction ID can undeniably prove this with absolutely no doubt.

Blockchain based intellectual property
If the timestamped signed content is original, authentic, non-stolen, non-copied, unplagiarized work then the user has a very strong argument to support intellectual property.
The immutable blockchain timestamp can become proof of prior art existence to any subsequent claim of authenticity by others in the future for the same or similar content.

2. How long does Blockbook™'s Blockchain stamping take?

How long does Blockbook™’s Blockchain time-stamping take?

The document hash digest calculation and the rest of the process up to the transmittal of the hash on the selected cryptocurrency network should not take more than a few minutes.

After the user has finalized this procedure, it normally takes 15 minutes to 1 hour for the blockchain posting to be confirmed with the appropriate number of confirmations.

Blockbook™ will then email you with a pdf certificate showing all the details of the timestamping.

3. How can I use my Blockchain timestamp in the future?

How can I use my Blockchain timestamp in the future?

The user (you) keeps the original electronic file of the document together with Blockbook™’s provided timestamp details included in the emailed PDF certificate. These timestamp details may be used in the future by the user in order to locate and refer to the appropriate transaction within the publicly available blockchain public ledgers.

There are currently various online services that provide easy access to the publicly available blockchains (some examples are,,,,

Direct links to these currently available online services will be included within the PDF certificate emailed to the user after the blockchain timestamping confirmation.

4. If I use the Blockbook™ app for a data or document, will I be able to prove authorship?

If I use the Blockbook™ app for a data or document, will I be able to prove authorship?

Blockchain stamping can certify the existence of an electronic documents’s content at a particular point in time.

When a user stamps a document, the document’s imprint (i.e. the SHA256 hash of the document) is publicly linked with a certain date & time.

As the document’s hash digest can be easily derived from the document itself, the user is able to prove that his/her document existed at that point in time because its hash digest is publicly linked to that particular point in time. The publicly announced hash cannot be used to derive the document itself thus it depends on the user when to disclose the relation between his document and the publicly timestamped document hash imprint.

If the user blockchain timestamps the hash digest of authentic original work which includes a detailed ownership statement or signature, then this publicly timestamped statement can be used in the future by the user to justify that the content was in his possession at that particular time.

Therefore, if the blockchain stamped document is indeed original authentic non-stolen & non-copied work signed by the user and if no other previous public statement on the stamped content may be found anywhere (including mass media, public authorities, agencies, companies etc) then the user has a very strong argument to support being the author/creator of the content.

Of course, if a third party can actually prove theft of the content prior to the time of stamping, then the ownership justification is discounted.

Thus, blockchain timestamp certification of ownership may be justified for content which is properly signed and is the result of original authentic work not having previously existed.

5. Is it possible to derive the document or file contents using the SHA256 hash imprint?

Is it possible to derive the document or file contents using the SHA256 hash imprint?

No, only the the hash imprint can be derived through a one way function from the original file but not the other way around. It is impossible to derive the original document or file contents using the cryptographic hash imprint.

For more information about the Cryptographic Hash please refer to this article on Wikipedia.

6. Is It Really FREE?

Is It Really FREE?

It is 100% FREE to Timestamp your data and documents in the public Blockbook™ Blockchain Network powered by the EOSIO Blockchain Platform, however, it is not free to timestamp on other public blockchain networks.

1. What is a Smart Contract?

What is a Smart Contract?

A smart contract is a computer protocol intended to digitally facilitate, verify, or enforce the negotiation or performance of a contract. Smart contracts allow the performance of credible transactions without third parties. These transactions are trackable and irreversible.

Smart contracts help you exchange money, property, shares, or anything of value in a transparent, conflict-free way while avoiding the services of a middleman.

The best way to describe smart contracts is to compare the technology to a vending machine. Ordinarily, you would go to a lawyer or a notary, pay them, and wait while you get the document. With smart contracts, you simply drop a bitcoin into the vending machine (i.e. ledger), and your escrow, driver’s license, or whatever drops into your account. More so, smart contracts not only define the rules and penalties around an agreement in the same way that a traditional contract does, but also automatically enforce those obligations. If you are looking for a more detailed walkthrough of smart contracts please check out our blockchain courses on smart contracts.


Suppose you rent an apartment from me. You can do this through the blockchain by paying in cryptocurrency. You get a receipt which is held in our virtual contract; I give you the digital entry key which comes to you by a specified date. If the key doesn’t come on time, the blockchain releases a refund. If I send the key before the rental date, the function holds it releasing both the fee and key to you and me respectively when the date arrives.

The system works on the If-Then premise and is witnessed by hundreds of people, so you can expect a faultless delivery. If I give you the key, I’m sure to be paid. If you send a certain amount in bitcoins, you receive the key. The document is automatically canceled after the time, and the code cannot be interfered with either of us without the other knowing since all participants are simultaneously alerted.

You can use smart contracts for all sorts of situations that range from financial derivatives to insurance premiums, breach contracts, property law, credit enforcement, financial services, legal processes, and crowdfunding agreements.

2. What is Ethereum & ERC-20 Tokens?

What is Ethereum & ERC-20 Tokens?

Ethereum (Ether) is an open blockchain platform made to run decentralized applications (smart contracts) worldwide. With fast and low-cost transactions.

ERC-20 Tokens ERC-20 is a standard that implements a token interface. That allow to store, receive and transfer units of value (tokens). A token can be a cryptocurrency a certificate of property or any representation of value.

3. What Can I Use Smart Contracts For?

What Can I Use Smart Contracts For?

Insiders vouch that it is extremely hard for our voting system to be rigged, but nonetheless, smart contracts would allay all concerns by providing an infinitely more secure system. Ledger-protected votes would need to be decoded and require excessive computing power to access. No one has that much computing power, so it would need God to hack the system! Secondly, smart contracts could hike low voter turnout. Much of the inertia comes from a fumbling system that includes lining up, showing your identity, and completing forms. With smart contracts, volunteers can transfer voting online and millennials will turn out en masse to vote for their Potus.

The blockchain not only provides a single ledger as a source of trust, but also shaves possible snarls in communication and workflow because of its accuracy, transparency, and automated system. Ordinarily, business operations have to endure a back-and-forth, while waiting for approvals and for internal or external issues to sort themselves out. A blockchain ledger streamlines this. It also cuts out discrepancies that typically occur with independent processing and that may lead to costly lawsuits and settlement delays.

Case history:
In 2015, the Depository Trust & Clearing Corp. (DTCC) used a blockchain ledger to process more than $1.5 quadrillion worth of securities, representing 345 million transactions.

Supply Chain
Smart contracts work on the If-Then premise so, to put in Jeff Garzik’s words,
“UPS can execute contracts that say, ‘If I receive cash on delivery at this location in a developing, emerging market, then this other , many, many links up the supply chain, will trigger a supplier creating a new item since the existing item was just delivered in that developing market.’” All too often, supply chains are hampered by paper-based systems, where forms have to pass through numerous channels for approval, which increases exposure to loss and fraud. The blockchain nullifies this by providing a secure, accessible digital version to all parties on the chain and automates tasks and payment.

Case history:
Barclays Corporate Bank uses smart contracts to log a change of ownership and automatically transfer payments to other financial institutions upon arrival

There’s no doubt that we’re progressing from slothful pre-human vertebrates to super-smart robots. Think of a future where everything is automated. Google’s getting there with smartphones, smart glasses, and even smart cars. That’s where smart contracts help. One example is the self-autonomous or self-parking vehicles, where smart contracts could put into play a sort of ‘oracle’ that could detect who was at fault in a crash; the sensor or the driver, as well as countless other variables. Using smart contracts, an automobile insurance company could charge rates differently based on where, and under which, conditions customers are operating their vehicles.

Real Estate
You can get more money through smart contracts. Ordinarily, if you wanted to rent your apartment to someone, you’d need to pay a middleman such as Craigslist or a newspaper to advertise and then again you’d need to pay someone to confirm that the person paid rent and followed through. The ledger cuts your costs. All you do is pay via bitcoin and encode your contract on the ledger. Everyone sees, and you accomplish automatic fulfillment. Brokers, real estate agents, hard money lenders, and anyone associated with the property game can profit.

Personal health records could be encoded and stored on the blockchain with a private key which would grant access only to specific individuals. The same strategy could be used to ensure that research is conducted via HIPAA laws (in a secure and confidential way). Receipts of surgeries could be stored on a blockchain and automatically sent to insurance providers as proof-of-delivery. The ledger, too, could be used for general healthcare management, such as supervising drugs, regulation compliance, testing results, and managing healthcare supplies.

4. What Can Smart Contracts Give Me?

What Can Smart Contracts Give Me?

Autonomy – You’re the one making the agreement; there’s no need to rely on a broker, lawyer or other intermediaries to confirm. Incidentally, this also knocks out the danger of manipulation by a third party, since execution is managed automatically by the network, rather than by one or more, possibly biased, individuals who may err.

Trust – Your documents are encrypted on a shared ledger. There’s no way that someone can say they lost it.

Backup – Imagine if your bank lost your savings account. On the blockchain, each and every one of your friends have your back. Your documents are duplicated many times over.

Safety – Cryptography, the encryption of websites, keeps your documents safe. There is no hacking. In fact, it would take an abnormally smart hacker to crack the code and infiltrate.

Speed – You’d ordinarily have to spend chunks of time and paperwork to manually process documents. Smart contracts use software code to automate tasks, thereby shaving hours off a range of business processes.

Savings – Smart contracts save you money since they knock out the presence of an intermediary. You would, for instance, have to pay a notary to witness your transaction.

Accuracy – Automated contracts are not only faster and cheaper but also avoid the errors that come from manually filling out heaps of forms.

The types of Smart Contracts you can build with our platform are:

A. Cryptocurrencies (Coins)
B. Crowd Funding
C. Initial Coin Offerins (ICO)

A. Cryptocurrencies (Coins):
1. A standard ERC-20 token implementation focused on gas saving, meaning that the users of your token will spend the minimum amount of ether in each transaction. This is recommended for personal or small projects.

2. A standard ERC-20 token implementation focused on security. This implementation improves the security of the smart contract, considering edge cases. This is recommended for public, valuable or sensitive tokens.

3. A standard Pistachio ERC-20 token implementation, so this is also focused on security, but also it has some advanced features for token management like ability to burn or mint tokens and pause/resume token activity.

B. Crowd Funding
1. A simple crowdfunding campaign that can receive contributions in Ether. The owner can spend the donations only on contributors approval.

C. Initial Coin Offerins (ICO)
1. A basic ICO that can receive contributions directly with a transfer in Ether or using a GUI with Metamask.

2. An advanced crowdsale to create Initial Coin Offerings that can receive contributions directly with a transfer in Ether or using a GUI with Metamask, plus optional features like a hard capped limit and opening and closing times.

8. Is Ethereum Safe & Secure?

Is Ethereum Safe & Secure? Ethereum is the leader in smart contracts platforms and is really strong and secure, but using a smart contract that hasn’t been properly tested and audited can compromise your project and your funds. In WP Smart Contracts we use only community audited smart contracts that have been proven to be trustworthy and safe.
