Ethereum Blockchain Directory
Overview

The Ethereum Blockchain Directory is a collection of files that have been uploaded to the Ropsten Ethereum Blockchain. You may Download and Upload files at the Directory for FREE. After uploading, you will receive a unique URL that will allow anyone to easily download your file.

The Ropsten Blockchain doesn't perform financial transactions and has no fees. You can receive 1 Free Ether from the Ropsten Faucet every day, which allows you to upload more than 12MB.

You may optionally encrypt any file with a password, which must be entered for your file to be downloaded.


Download Files

To Download a file, click a File Name in the Blockchain Directory list. This will display that file at the top of the page, with a Download button.

When you click the Download button, the selected file will be downloaded to your 'Downloads' directory.

Password protected files: If 'Yes' is displayed in the Password column, then you will be prompted to enter a Password (to the right of the [Download] button).


Searching and Sorting

You may Filter the list of files that are displayed in the Blockchain Directory, by selecting Filter Field #1 and/or Filter Field #2 from the dropdown boxes, and entering Filter Criteria into the textbox to the right of each Filter Field dropdown box. You can select just one Filter, or both.

The Filter Criteria does not have to contain all the characters in the selected Filter Field. For example, if you entered 'mid' as the Filter Criteria, files containing 'mid' anywhere in the selected Filter Field would be retrieved.

You may begin a search by clicking [Apply Filters], or by pressing [Enter] when the cursor is in either Filter Criteria textbox.

Sort: You may Sort the files that are shown on the grid, by selecting a Sort Field from the dropdown box, and indicating Ascending or Descending in the Sort Order dropdown box.


Upload Files

Ropsten Address and Private Key: To Upload files, you must have a Ropsten Address and Private Key. If you do not have a Ropsten Address, click [Receive a new Ropsten Address], and a new Ropsten Address and Private Key will be displayed.

Your Ropsten Address must contain Ether to pay the 'gas' that is charged by the Ropsten Blockchain. You can receive 1 Free Ether from the Ropsten Faucet every day, which allows you to upload more than 12MB.

File Information: After you have received a Ropsten Address and Private Key that contain Ether, you can complete the form shown under "Upload File Step #2", which contains the following fields:
  • Description: Enter up to 32 characters which describe the file that you are uploading.
  • Keywords: Enter several Keywords, separated by commas, which will allow the file to be found if the user Filters the Directory by the Keywords column.
  • Password: This optional field will cause your uploaded file to be encrypted. The file may only be downloaded if that Password is entered.
    Important: A password-encrypted file consumes twice as much memory, so it costs twice as much 'gas', and takes twice as long to be uploaded.
  • Show in Directory: This box must be checked for the file to appear in the Blockchain Directory. However, the Creator (the user who uploaded the file) will see all their files, even if Show in Directory is unchecked.
  • Downloadable: This box must be checked for the file to be Downloadable.

Select File to Upload: The final step is to click the button to the right of Select a file to Upload:, and then choose a file. The screen will display an estimate of the time that will be required for the file to be uploaded. As described before, a password-encrypted file will take twice as long to be uploaded.

Ether and Time Estimates: The following calculations will estimate the Ether and Time required for an Upload:
  • Ether used for 'gas' = {Kilobytes * 0.00008}. For example, 1,500K would cost about .12 Ether.
  • Minutes to complete Upload = {Kilobytes / 250} to {Kilobytes / 125}. For example, 1,500K would take from 6 to 12 minutes to upload.

Download URL: When your uploaded file appears in the Blockchain Directory, you may give out the Download URL that is shown in the directory. The Download URL will cause your file to be initially selected when this website is displayed.


Edit File Information

Before you may edit files, you must click [Submit Ropsten Address and Private Key] to verify that you are the Creator of the files that you want to edit.

The Blockchain Directory will then display an [Edit] button in the Creator column for each file that you had Uploaded.

Clicking an [Edit] button will display an overlay frame allowing you to edit the File Information that you had previously entered.

Please note: You cannot delete data from the blockchain, so if you don't want anyone to download your file you should uncheck [Show in Directory] and [Downloadable].

When you click [Save Changes], it may take a minute before your changes will appear in the Blockchain Directory.


Save Parameters to Short URL

You may save the settings of all Sort and Filter parameters to a short URL, so you can easily reload the same settings.

Click the [Save] button (on the upper-right portion of the page), and an overlay frame will display the short URL. Click in that textbox, and you can copy the short URL to the clipboard (by pressing [Ctrl+C]).

Event Log Explorer
Overview

This feature can be displayed by clicking the Event Log Explorer link on the upper-right corner of the home page, or by clicking this link: Event Log Explorer

This webpage retrieves data from Event Logs in the Ethereum Blockchain. The 30 most active Dapps are shown in a dropdown box, or you can enter any other Dapp Contract Address.

The data is displayed in a grid that can be Sorted by an field, and Searched by any two fields. You may also enter a Time Span, from 'One Hour' to 'All Days'.

Display the Sum of any field. For example, calculate the total deposits for any ether address.

Save the parameter settings to a short URL, so you can easily reload the same settings.


Selecting Event Logs

The 30 most Active Dapps are shown in the Dapp dropdown box. When a Dapp is selected, the Event dropdown box contains the Events that are exported by the selected Dapp.

To see Events for Dapps that are not shown in the Dapp dropdown box, enter an Address in the New Dapp Contract Address textbox, and press [Enter] (or click [Display New Dapp]). You must then select an Event from the Event dropdown box, before Event Logs will be displayed.

Time Span: The Time Span dropdown box allows you to select the earliest date/time that Event Logs are retrieved.

A maximum of 1,000 Event Logs are displayed for each search, so if you select a large Time Span, all the Event Logs may not be displayed. If you select a small Time Span, then sometimes no Event Logs will be displayed. For example, if you select 1 Hour, then no Event Logs will be shown unless they occurred in the past hour.


Searching, Sorting, and Summing

You may Filter the list of Event Logs that are displayed, by selecting Filter Field #1 and/or Filter Field #2 from the dropdown boxes, and entering Filter Criteria into the textbox to the right of each Filter Field dropdown box. You can select just one Filter, or both.

The Filter Criteria does not have to contain all the characters in the selected Filter Field. For example, if you entered '834' as the Filter Criteria, Event Logs containing '834236762' or '000834' in the selected Filter Field would be retrieved.

You may begin a search by clicking [Apply Filters], or by pressing [Enter] when the cursor is in either Filter Criteria textbox.

Range of Dates: The Filter Criteria #1 textbox may contain a Range of Dates, separated by a hyphen. For example, "01/10/19-01/15/19" will retrieve Event Logs that are Dated on or after 01/10/19, and on or before 01/15/19.

Sort Event Logs: You may Sort the Event Logs that are shown on the grid, by selecting a Sort Field from the dropdown box, and indicating Ascending or Descending in the Sort Order dropdown box.

Show the Sum of any Field: You may Sum the Event Logs that are shown on the grid, by selecting a Sum Field from the dropdown box. The Total of all numeric values in the selected field will be shown to the right of the Sum Field dropdown box.


Show Distinct Entries (for Sort Field)

Clicking this button will display an overlay frame which lists the Distinct Entries for the field selected in the [Sort Field] dropdown box, and a Count for each entry.

For example, if a field named 'account' is selected in the [Sort Field] dropdown box, then you will see how many Event Logs Entries each user created. This feature allows you to see which users are performing the majority of a Dapp's actions.

If the [Sort Field] dropdown box is set to 'Date/Time', then the Distinct Entries will show you how many Event Logs occurred on each Date.


Select Initial Dapp

You may select the Dapp that is initially used by this website, by adding one of the following two parameters to the website's URL:

Save Parameters to Short URL

You may save the settings of all parameters to a short URL, so you can easily reload the same settings.

Click the [Save] button (on the upper-right portion of the page), and an overlay frame will display the short URL. Click in that textbox, and you can copy the short URL to the clipboard (by pressing [Ctrl+C]).


Search Ether Transactions

These features can be displayed by clicking this link: Search Ether Transactions

When the Search Ether Transactions home page is displayed, enter an Ether Address and click [Search Transactions].

This module has the same Sort, Filter, Sum, and Save features as the Event Logs module, which were previously described in this Help file.

Micro Token: Most Tokens use the Wei numeric system, which is: 1000000000000000000 units = 1 Token.
However, some Tokens use the Micro numeric system, which is: 1000000 units = 1 Token.

The Sum Field dropdown box allows you to select between these two numeric systems.

If the [Token Value] column contains all zeroes, then select Micro Token in the Sum Field dropdown box.


Augur User Report

These features can be displayed by clicking this link: Augur User Report

This report lets you view the Net Proceeds of every Augur User (since Augur was launched in July 2018), and the last activity of each user.

Net Proceeds: This data is received from the getAccountTransferHistory function in the Augur API. This report adds all the REP and ETH withdrawals that each user has ever made, and subtracts all their deposits, to calculate their Net Proceeds.

The Net Proceeds are shown for the following time periods:
  • All-time
  • Last 30 Days
  • Last 7 Days
  • Last 24 Hours

Last Activity: The date is shown for the last time that each user performed the following actions:
  • Market Created
  • Order Created
  • Order Filled
  • Dispute Contribution
  • Report Submitted

You may click any date to see the Market that the action pertained to.

Filter Settings: You may filter the report by Market ID, Low Date, or High Date.

For example, you may retrieve all users that performed any action pertaining to the Midterm Election Market, by entering 0xbbbc0a8baa03535e0a680ee2f057162aaaafd570 in the Market ID field.

This module has the same Sort and Save features as the Event Log Explorer, which were previously described in this Help file.
