Switch in data center room

Infrastructure update

Wow.. 245 days have passed since the last big Maintenance work in the infrastructure. And more then 1 Year since the last upgrade.

Even if a high Uptime is considered good and the servers are present on the world map 24/7 it’s time for an infrastructure update. As the entire world is in isolation and i’m working from home I see an opportunity as I  have found the needed time to perform an overhaul of the servers.

The planned changes are:
Timeline 02-05 May 2020
– Upgrade the storage of each VM to 1 TB Disks. Right now each is using 3/4 of the allocated space and in order to grow without problems it would be good to provision it upfront.
– Update the Data center infrastructure by updating the software for hosts, the management, storage, performing driver and firmware updates, etc.

Timeline 29.05-02.06*
Hardware Upgrade –  Server Upgrade increasing capacity of compute and storage.

Again on the Tronscan Map..

And.. we are again back on the map! (14.09.2019 – 9 AM GMT+2)

How come we’ve disapeared?
Sadly.. in Romania, it seems that we are the only server (tron nodes) operators. There were some folks who ran the nodes but now ours are the only one. Once we dropped back to 10.. puf, the country was removed from the map.

Screenshot (before)

In order to address the issue I’ve deployed the 11th node. Now, all 11 that are shown on the maps belong to this SR Candidate (TronLabs Romania)

This is how it looks now

Odyssey-v3.6.0 was released

On the 21st of June 2019 the latest Odyssey version 3.6 was released. This introduces new TVM instructions, API, protocol data check as well as optimizations.

New Features

  • #2070 Add create2 instruction for TVM, which returns a predictable contract address before deploy. TIP #26
  • #2069 Add bitwise shifting instructions for TVM to reduce energy consumption of shift. TIP #29
  • #2075 Add extcodehash instruction for TVM which returns the keccak256 hash of a contract’s code. TIP#30
  • #2125 Add triggerConstantContract API to support contracts which have no ABI. TIP #31
  • #2125 Add clearABI API including http and grpc, contract’s deployer can use this to clear his contract’s existed ABI. TIP #32
  • #2093 Add built-in message queue for event subscribe. TIP #28
  • #2047 Add protocol data check
  • #2154 Add the Permission_id field when returning the created transaction, compatible with multi-signature transactions

Changes

  • #2142 Support event subscription without abi
  • #2173 Optimize erengy deduction strategy in TVM when transfer 、sendor transferToken failed
  • #2141 Optimize the HTTP interface by adding the visible parameter to support the convenience type of addresses and strings, and add the AccountID related interface
  • #2182 Optimize http/grpc broadcast transaction interface
  • #2155 Optimize the process of block broadcasting
  • #2219 Fix the problem that the http interface parses the long type value for a long time.

Notices

  • Add built-in message queue config. See here
    use event.subscribe.native.useNativeQueue to control whether using built-in message queue . If true, use native message queue, else use event plugin.
    use event.subscribe.native.bindport to control bind port.
    use event.subscribe.native.sendqueuelength to control max length of send queue.
  • For smart contact without ABI (after clear ABI or deploy without ABI)
    If you want to call the constant method, you must use the triggerConstantContract interface instead of triggerContract . More details: TIP #31
    If you need event subscription, you need to subscribe to and upload ABI using version 3.6+. More details: tron-eventquery.md
    After clearABI, it is not possible to re-add ABI to the same contract address.
  • For create2 instruction
    If you want to use create2 to genertate a new address . More details: TIP #31
    After suicide, the storage of create2 addresses will be reset.
    If deployed on a normal address (created by transfer trx), the address will be modified to the contract address. The resources (bandwidth and energy) previously delegated to this address are cleared, and do not affect the unfreeze operation of the client.

Bucharest Blockchain and DPoS is safe !

A few days ago I received the following message via e-mail from the Meetup Site.

Save Bucharest Blockchain and DPoS

The Meetup group that I’ve attended and got inspired to run for TRON SR was going to disappear in a couple of days, if no one would step up and save it.
Knowing that it might be an issue with the payment or just some glitch, I told myself to be patient and wait for a couple of days. I’ve waited until the 2nd of March at 10 PM. No renewal and no one else stepped up so I had to act.

Now our Meetup group is safe. I plan to continue what Crypto Girls have started and help our community to succeed. I plan for both in person meetings as well as for virtual ones.

Stay tuned for more.. good things are coming our way.
