Bitcoin 09 v0.1.11

Bitcoin 09 v0.1.11

Changes:

• Adds explorer supply endpoints for listing/audit integrations:
  • /api/supply
  • /api/circulating_supply
  • /api/circulating-supply
• Excludes the burned genesis reward from circulating supply.
• Adds halving and emission fields to /api/status.
• Adds a fast path for normal tip extension so node/explorer startup no longer replays the full chain from genesis for every stored block.
• Adds QUICKSTART.md and a simple markets note for early community OTC trading.
• Adds Discord setup support for #??-otc-trading.

Notes:

• There is no official 09C price.
• Early trading is community OTC only.
• Current block reward remains 50 09C.

Bitcoin 09 v0.1.10

Bitcoin 09 v0.1.10

Sync and wallet-display improvement release.

• faster fresh-node sync: peers now send bounded batches of up to 64 blocks instead of one block per round trip
• balance changes now log immediately when the local chain sees them, instead of only waiting for the 30 second heartbeat
• startup update notice: mainnet nodes check GitHub for a newer release and print a notice if one exists
• added -no-update-check for users who want to skip that check
• docs now show how to run a node without mining

Run a node without mining:
btc09 node

Mine:
btc09 node -mine

Bitcoin 09 v0.1.9

Bitcoin 09 v0.1.9

Block explorer release.

• new: built-in web block explorer, run with -explorer :8009
• shows height, difficulty, supply, peers, recent blocks, block detail and address balances
• JSON status at /api/status
• public instance: http://82.22.32.82:8009

Bitcoin 09 v0.1.8

Bitcoin 09 v0.1.8

Maintenance release.

• btc09 version now reports the real release version (was stuck saying v0.1.0)
• includes all v0.1.6/v0.1.7 sync and fork-recovery fixes

If you downloaded v0.1.0 or v0.1.1: those builds have no built-in seed and a
sync bug. Upgrade and just run:

btc09 node -mine

The seed 82.22.32.82:9009 is built in from v0.1.2 onward.

Bitcoin 09 v0.1.7

Bitcoin 09 v0.1.7

Network hardening release.

• v0.1.6 fixed catch-up from stale forks
• v0.1.7 disconnects peers that keep sending invalid fork blocks instead of logging them forever

Upgrade recommended for all miners and seed nodes.

Run:
btc09 node -mine

Bitcoin 09 v0.1.6

Bitcoin 09 v0.1.6

Network sync fix.

This release fixes peer catch-up when a node is behind or has mined on a stale fork:

• block sync now requests the next received height instead of tip plus one
• orphan recovery walks back and rebuilds the competing branch
• seed write queues no longer explode during catch-up

Upgrade is recommended for all miners. If your node was stuck behind the seed, restart with this release.

Run:
btc09 node -mine

Bitcoin 09 v0.1.2

Bitcoin 09 v0.1.2

Display ticker update:

• project name stays Bitcoin 09
• ticker is now 09C
• binary names remain btc09 for compatibility
• consensus salt remains BTC09/pow/v1 so the already-launched chain is not forked

Run:
btc09 node -mine

Bitcoin 09 v0.1.1

Bitcoin 09 v0.1.1

This release makes BTC09 closer to Bitcoin's original rules:

• mainnet difficulty retarget interval is now 2016 blocks, same as Bitcoin
• the first seed node is built into the client, so btc09 node -mine works without passing -seeds
• added BOOTSTRAP.md for the early network plan
• source archive now includes the btc09 CLI source

Seed node:
82.22.32.82:9009

Run:
btc09 node -mine

BTC09 remains the same idea: Bitcoin economics, CPU proof of work, no premine.

Bitcoin 09 v0.1.0
