New Bedford Upgrade: The Moment of Setting Sail on the New Mainnet
On February 17, 2026, we read together the official News and About, current ledger verification data, and migration criteria for the New Bedford upgrade.
To understand BTCMobick recently, the New Bedford upgrade is indispensable. The official About and News record the mainnet rail switch and address migration completion on February 17, 2026, as key events.
This event is more important than a simple announcement. Understanding the previous ledger, current mainnet, address migration, and explorer distinctions together prevents users from being confused about which ledger they are currently viewing.
On this page, New Bedford is described as 'the event where the new mainnet started at BTCMobick's current height 0, different from Bitcoin's block 0.' The previous mainnet 556760 is a record of past departure, and the current mainnet map restarts at height 0.
Plain words
First-time terms
- New Bedford
- The name of BTCMobick's recent mainnet transition event.
- Rail switch
- An official term meaning the base on which the current ledger operates has changed.
- Current ledger
- Refers to the current BTCMobick ledger read under the new rules after New Bedford.
Learning objectives
- Understand the New Bedford upgrade as the current mainnet transition event.
- Review official announcements and current ledger verification data together.
- Distinguish between the previous explorer, previous mainnet migration site, and current explorer.
Official Records and On-Chain Verification
The official About records the New Bedford upgrade and address migration completion. The current ledger verification data shows height 0 in January 2026 and the migration period in February 2026.
Here, height 0 is not Bitcoin's block 0 but the new starting point of BTCMobick's current mainnet. In other words, it is the basis for reading the rules after New Bedford and the current explorer.
In learning materials, it is safer not to merge these two but to view the official event description and ledger verification values side by side.
Why Do Two Explorers Appear?
Official links show both pre-New Bedford and post-New Bedford explorers. Beginners should first learn that the same project contains both the previous ledger and the current ledger.
If the ledger names are omitted, the same height numbers or address migration stories easily get mixed. Especially, the previous mainnet 556760 should be read as a record remaining in the migration site, not the current mainnet.
Details of the New Bedford Upgrade
For New Bedford, the migration targets and results are more important than the name. Official News provides details such as the number of addresses, number of UTXOs, total migrated BMB, maintenance of the existing chain's safety net, and non-migration of transaction history.
When examined deeply, numbers like 235,230 addresses, 382,060 UTXOs, and 3,879,641.131 BMB are verified separately through official explanations and migration records. Balance migration and past transaction history migration are not the same thing.
In the next reinforcement, user-perspective verification procedures will be added: how to check current balances on the new chain, how to check past traces on the previous explorer, and why the two screens look different will be separated.
The Upgrade Changes the User's Viewing Window
New Bedford is not just a topic to memorize by name. It changes which ledger the user views, which explorer they check, and where previous records are stored.
Therefore, this lesson is closer to a guide than upgrade promotion. Dividing the roles of the previous mainnet, migration site, and current mainnet helps users get less lost in actual queries.
Memory Points
Points to remember
Understanding New Bedford on One Screen
Officially, New Bedford is an upgrade, but to beginners, it looks like the explorer, address migration, current ledger, and previous ledger all changed at once.
Therefore, explanations should start with 'Which ledger are you currently viewing?' rather than the event name. The previous mainnet 556760 is a migration site record, and the current height 0 is a new mainnet starting point different from Bitcoin's block 0, which makes understanding easier.
Official News and About explain the event, while current ledger headers and migration criteria data handle actual ledger verification.
New Bedford Is the Starting Point of a New Voyage
The New Bedford upgrade is not just a name change but an event that makes the current mainnet read under new rules and a new baseline.
Records of the existing ledger do not disappear but remain in the previous mainnet and migration site. The ledger users currently view takes a different path from height 0.
If you view this structure like a treasure map, 556759 is the reference island of the old route, and the current height 0 is the port where the new voyage begins.
Address Migration Is Not Just Numbers but User Experience
The official address migration numbers show the scale of the upgrade. However, more important to users is which explorer they should view and what.
Since previous records, current balances, and new transaction queries may lead to different screens, ledger boundary guidance is necessary.
The New Bedford lesson trains users to distinguish between past maps and current maps to find their way.
Practice
Create an Upgrade Card
- Write '2026-02-17 New Bedford Upgrade'.
- Create four boxes next to it for official records, current ledger height 0, previous mainnet migration site records, and explorer distinctions.
- Attach one source ID to each box.
Learners can explain New Bedford as a recent event requiring both announcements and ledger verification.
Review New Bedford Guidance Phrases
- Explain New Bedford in one sentence as the new mainnet starting point.
- Write that previous mainnet records are not lost but checked in a separate window.
- Indicate separately the reference point users should see when querying current transactions.
Learners explain the upgrade focusing on ledger boundaries and user experience rather than just the event name.
Key takeaways
- New Bedford is a key event for understanding BTCMobick's recent ledger.
- The current mainnet's block 0 is not Bitcoin's block 0 but the starting point of new rules.
- Official explanations and current ledger verification data must be viewed together.
- Distinguishing previous mainnet and current mainnet is essential for beginner explanations.
- New Bedford should be read as an event that changes ledger boundaries and query paths rather than just a name.
