Horizon Survey

SDF is creating technical roadmaps for all of their projects this year, and they are looking looking for feedback on Horizon. If you've used Horizon extensively in the past, please fill out this survey.


9.76% of Accounts Performed 10+ Transactions in the Past Month

LongHash - a blockchain data analysis firm - studied accounts on the Stellar network to identify the best recipient accounts for a theoretical airdrop. Their analysis indicates that 87% of accounts on the network have less than 10 lumens, and 9.76% of accounts performed 10 or more transactions in the past month. While the research is interesting, airdropping projects cannot target accounts in this way due to the need for trustlines and the related increase in the minimum account balance.


Kelp v1.3.0 released

New Kelp - an open-source trading bot for the Stellar DEX - updates:

  • mirror strategy supports offsetting trades on the backing exchange to reduce asset risk
  • balanced strategy reduces noise from unnecessary re-randomization of offers
  • support for randomized time intervals to avoid exploitation of kelp bot


SatoshiPay Launches Full Validators

SatoshiPay - a micropayments provider - has been operating basic validators for over a year and recently launched a cluster of three full validators in Iowa, Frankfurt, and Singapore. A basic validator participates in consensus but does not store the full history of the network, while a full validator both participates in consensus and stores the full network history. A full validator helps other nodes join the network and improves the resiliency of the network. According to SatoshiPay, they join three full validators from SDF, two from Coinqvest, and two from Lobstr.


Proceeding with Caution – a Survey on CBDCs

According to a survey of central banks by the Bank for International Settlements, a majority of central banks are researching CBDCs (central bank digital currencies), but "only a few intend to issue a CBDC in the short to medium term." The report focuses in on two countries where the circulating cash supply has decreased - Sweden and Uruguay - and their respective general purpose CBDCs - the e-Krona and the e-Peso.

Note: These are not on the Stellar network.


Deconstructing Decentralized Exchanges

Lin, Legal Counsel at Interstellar and the Stellar Development Foundation, lays out the the technical differences between different decentralized exchanges (0x, Stellar DEX, IDEX, EtherDelta, Bancor, Airswap, etc.) in an explanatory overview of decentralized exchange architecture for the Stanford Journal of Blockchain Law & Policy.

Stellar Protocol Values Released

SDF details “Stellar Protocol Values” to help guide people as they are submitting protocol changes (CAPs). Highlights:

  • “Stellar network should facilitate side-chain transactions to enable sub-networks.”
  • “The Stellar network should support decentralization wherever possible, but not at the expense of the majority of its values.”
  • “We should not over complicate the protocol itself, and the more outside of the core protocol, the better.”
  • Heavy emphasis on filtering changes through the goal of cross-border payments.

'Most financial institutions are not going to use bitcoin'

Yahoo Finance interviews McCaleb. Highlights:

  • "If it’s not a public chain, then you’re missing the point."
  • "In the rest of the cryptocurrency world now, there’s this big push for tokenizing different things, and now there’s the stablecoin hype, and Stellar has sort of been doing this all along, we just weren’t calling it that."
