Dieser Post ist dafür gedacht die Serverkosten für SteemWorld.org zu decken und mir in Zukunft weitere Entwicklungen zu ermöglichen.

One step forward, two steps back...

As always, it was a very busy week for me. In parallel to implementing the new Block Explorer I fixed a few bugs in my RC calculation logic and changed all API requests on the client and server side to use the new Condenser API. It's a bit disappointing to see that the available Steem JS Library is still a few weeks behind the important changes made in HF20. Lesson learned: Build your own solution whenever it is possible or you will have to rely on others. Changing all my code to use DSteem instead would take too long and I want to make progress here. But I'm glad about what I have accomplished and as we know: Inspiration is important, but most important experience comes from 'learning by doing'...

Block Explorer now available

- Transactions, same layout as in Account Operations: https://cdn.steemitimages.com/DQmaY5cCf8EvmHJ9WaejWFc7HEoUhu7aZXuAevwkppdPCX5/steemworld-block-explorer-1.png - Virtual Operations in a separate tab: https://cdn.steemitimages.com/DQmQT4sJrYRUm4ABfLZ94TByuaJNbjeMbm4ErQo4j1jpYCo/steemworld-block-explorer-2.png The reputation next to the account names is only being shown for already (on SteemWorld) cached accounts. I'm not sure, if I will change that in future, because it would require a huge amount of 'get_account' requests for larger blocks. https://cdn.steemitimages.com/DQmSxLGUHKzQG959mynpDEomMYAxfUcgjyD4vHdF1Js2J4e/steemworld-block-explorer-3.png - Exporting blocks and virtual operations as JSON: https://cdn.steemitimages.com/DQmYc4ir77ovvTNyQPQvrrxQSdeyHJLYrQoRVJ6SztuZeVk/steemworld-block-explorer-4.png https://cdn.steemitimages.com/DQmZtMaTLutv9CoyeJEZz3hEGrboyygXaNA38TEav4MKXk8/steemworld-block-explorer-5.png - Account Operations: A click on the transaction id or block number opens the Block Explorer in a popup and automatically filters the displayed data: https://cdn.steemitimages.com/DQmZNKKRsKom6vgbXP1fWW6SALbPXgWJh5jaWYQHcZyZpJ4/steemworld-block-explorer-6.png https://cdn.steemitimages.com/DQmfTP6iLBSDWUtNPTZgAWFAmnbLshU8F1EE2NBoot7RvGF/steemworld-block-explorer-7.png - The same goes for virtual ops: https://cdn.steemitimages.com/DQmRwhrbWbUtsMX1kiqdmvqoSyWMwMa6w8gR87bhA9hhjS4/steemworld-block-explorer-8.png https://cdn.steemitimages.com/DQmZaP7EV4rkMCgB21Ag61SKiJ8BSgXv81caFa7DaaWZpgK/steemworld-block-explorer-9.png https://cdn.steemitimages.com/DQmd5zGRvKoXedkoVKpEFimSwoYtXkvSb3Dw7778FSw9amw/steemworld-block-explorer-10.png - There is also a field for filtering the transactions of the opened block by text: https://cdn.steemitimages.com/DQmZ2KoRTYE8BAN3bjX1y8XwD7pRXoGetdM78PtSnJ2MTQP/steemworld-block-explorer-11.png - Additional information for each transaction can be shown by clicking on the icon in the right: https://cdn.steemitimages.com/DQmP9cd9k7T17D4TgsVYUrJaRqo7yPhA1v1EV5HGvZ4SqVX/steemworld-block-explorer-12.png - It is also possible to open the Block Explorer directly from an external link: ```https://steemworld.org/block/[block_num]``` or ```https://steemworld.org/block/[block_num]/[trx_id]``` https://cdn.steemitimages.com/DQmbYakCwq4m8xPdHEv2xRVGfxAcZPdapDXZecrZgf2WBCB/steemworld-block-explorer-13.png - Holding ```Ctrl``` while clicking on a block number or transaction id on SteemWorld will also open it in a new tab ;)

In the making

Improving the account refresh logic

Since the RPC nodes do no longer synchronize/return the account history and main account data in real time, I need to think about building and implementing a better solution. Maybe I can parse and store all blockchain data on one of my servers without having to rely on public node requests from the clients in future. I already do parse all blocks for some features on SteemWorld, but I do not have a solution for the account history yet. Would be great to store also the virtual operations, because that would enable me to have kind of a public node for my services without having to fulfil the huge hardware requirements for running a full steemd instance. I will take a look at Steemit's SBDS (Steem Blockchain Data Service), because I think it could be capable of exactly what I need. I prefer to work with SQLite as it is really fast on SSD and requires no additional database service working in background. As I stated before, in my opinion it would be possible to deploy kind of an own Full-API Service on a 16 GB RAM machine with enough SSD memory available. That would be much cheaper than running steemd and is the only solution I can think of given my current monthly earnings.
