I am a software developer based in Cambridge, UK. My work and expertise is focused largely on the STEEM blockchain. I support the growth of the network by maintaining a witness node, by developing applications, and community tools engineered to empower this emerging ecosystem.

I am a Utopian Moderator. I review submissions in the development category.

I am currently the 7-th most delegated account - currently 299 delegators! on the STEEM Blockchain.

Delegation

@justyy is the 7-th most delegated (299 Delegators ↓1) project on steem blockchain (See below).

Delegation Rewards

In last 7 days, 114.0440 SP were given out to the 299 delegators. Thank you!

The steem price is low and hence more delegations to @justyy as his delegation return APR% still stays the same.

Revenue and Expenses

1. Monthly SteemSQL cost: 10 SBD
2. Monthly Costs for Two Witness Nodes: around 100 USD
3. Monthly API server costs: around 150 USD
4. Monthly Domain Costs: 5 USD
   And not to mention time and efforts spent on: developing new tools, monitoring and upgrading the witness servers. It is profitable only (especially under such low STEEM price) if you are at Top 50, so please do support me by voting me as a witness or set as a witness proxy. Thanks.

I like STEEM and I do believe the STEEM - that is why I have been spending money and efforts on being a witness and promoting STEEM community via developing tools/applications, providing APIs, helping Utopian moderating work etc.

Delegate to @justyy

@justyy runs a automatic delegation service for a long time. Delegate to @justyy for at least 5 SP and start receiving daily payout as interests (from 8% to 10% APR). Also, as a supporter, the delegators will start to receive complimentary/curation upvotes (as a thank you) per day from e.g @justyy and a few other curation trails. For more information, read this. The voting weight algorithm is open source.

• Delegate to @justyy - at least 5 SP to join (automatically)
• Undelegate to @justyy (Quit) - SP returned by steem blockchain in 5 days
• View Current Delegators/Supporters

299 Delegators! Thank you!

@justyy is the 7-th delegated project on steem blockchain

Please note that the SP you enter is the final amount to delegate. For example, if you already delegate 10 SP and you want to delegate another 5 SP, you will need to enter 15 SP (instead of 5 SP) in the delegation form.
